The Swedish Model
... for integrated water and waste water
management

• In Sweden the private and public water sector has
  worked with the device that high standards for
  water supply and sewage is the basis for high
  living standards. To reach those objectives it is
  necessary to consider the overall water
  situation, which is the foundation of the Swedish
  model.
• The Swedish model means putting all of the pieces
  together. Social, environmental and technical
  aspects. To ensure sustainable water usage,
  reliable water supplies, better water quality,
  environmental stewardship, efficient urban
  development, protection of agriculture, and a
  strong economy.
• In more detail this means an integrated view
  regarding waste water treatment, drinking water
  supply, rain water treatment, sanitation and
  energy production. The model has, regardless of
  project size (e.g. single plants or entire
  regions), rendered in optimised usage of water,
  raw materials and energy both in short and long
  term.
• The key driver of the Swedish Model is the close
  collaboration between Swedish private and public
  water sector, academia, financing and
  governmental bodies, which has resulted in a
  world leading water and waste water management.

Drinking Water Supply
Benefits Safeguarding public health Sustainable
production systems

• Rationale
• Nothing has greater impact on our lives than
  water. Water is fundamental for our health,
  comfort and prosperity. We believed water to be
  an endless resource, and Nature would take care
  of any irresponsible misuse. Today, we know
  better! CleanWater has the knowledge and
  experience to handle any aspect of fresh water
  production, from an sustainable point of view.
• History
• Swedish members of the CleanWater have worked
  within this area for over 140 years! Export
  started 1903! In the early days focus was on
  providing freshwater and fire fighting. Today the
  focus are from a broader perspective including
  environmental, social and economical effects,
  reaching from a whole region to a single plant.
  The development in Sweden has given the
  CleanWater Group members an extensive experience
  and knowledgebase. Only in Sweden, the CleanWater
  Group members has designed, constructed, serviced
  and maintained more than 2000 public water
  plants. This knowledge and experience has been
  exported throughout the globe, to more than 100
  countries.

Wastewater Services and Systems
Benefits Sanitation Decreased eutrophication

• Rationale
• Adequate wastewater treatment is fundamental in
  order to avoid sanitary and health problems in
  populated areas. It also serves as a measure for
  environmental protection, thus preventing
  contamination and eutrophication of receiving
  waters. Another aspect of wastewater treatment is
  the potential for nutrient recovery re-cycling
  of nutrients for fertilisation of cultivated
  land. 
• History
• Thanks to its long history of municipal
  wastewater treatment, today Sweden has one of the
  most far-reaching effluent standards in the world
  for treated wastewater. Sewage treatment plants
  were introduced as early as the 1930s.
  Mechanical treatment was followed by biological
  treatment in the 1950s and chemical treatment by
  means of precipitation in the 1970s, thereby
  reducing discharges of the nutrient phosphorus.
  During the final decade of the century, nitrogen
  reduction was introduced for all major coastal
  plants.
• Projects
• The several thousand reference projects covers
  all the aspects within this business area, from
  the idea stage through feasibility,
  planning/designing, construction, management and
  monitoring of new or existing water or waste
  water plants in conjunction with energy
  production facilities, to turn-key and functional
  sales contracts. Demonstrations and educational
  services can be provide around the globe as well
  as funding support.

Bio Gas Energy Production
Benefits Decreased environmental impact Waste
to raw-material Renewable fuel production

• Rationale
• One of the laws of nature states that energy
  cannot be destroyed. It can never be used up,
  only transferred between bodies and converted
  into different forms. It is also true that energy
  can destroy. Poorly utilized energy can have a
  negative effect on both the environment and
  financial profits. Fortunately, there are many
  good examples of sensible and efficient energy
  applications, creating biogas is one of them.
  Biogas is recovered from biological waste such as
  sewage sludge and food and farm waste. It is an
  efficient, renewable form of fuel that does not
  compound the greenhouse effect since there is no
  emission of carbon dioxide. Furthermore, biogas
  emits considerably less nitrogen oxides, carbon
  oxide, carbon monoxides and hydrocarbons than
  petrol and diesel.
•  
• History
• Production of biogas has been a known technology
  since the middle of the 19th century. In Sweden
  it became more commercially used during the
  energy crisis in the 70s. One of the first
  commercial biogas recovery plants was built in
  Sweden in the early 90s. This product evolved
  from the broad experience within energy systems,
  which also has positioned the CleanWater partners
  in the forefront of product development. The RD
  within the area has given new state-of-art low
  emission and high-yield products, which covers
  all the stages from design and  construction to
  turnkey renewable fuel production plants.
• Projects
• The CleanWater's genuine experience provides Bio
  Gas -Energy Production solutions, from design to
  turn-key responsibility, covering the whole
  production chain. That is from the wastewater
  treatment plant to biogas to fuel, ending with
  infrastructure for refuelling vehicles. In recent
  years, many municipalities, transportation firms
  and bus companies have chosen the partners of
  CleanWater to design, build and service gas
  refinement plants and filling stations worldwide.
  CleanWater is well experienced to raise funding
  together with the client for these projects.

Planning of Water ResourcesReference project
Lyckebyån

• Background
• The new EU framework about water means that all
  water resources are supposed to be planned on
  river basin level. The river Lyckebyån concerns
  three municipalities and three counties in the
  southeast of Sweden. To have influence on coming
  rules for the use of the water resource in
  Lyckebyån the three municipalities Emmaboda,
  Lessebo and Karlskrona intend to provide the
  water authority with a vision plan.
• The project
• The legal Association of River Lyckebyån,
  including the three municipalities, decided that
  the best way to influence on the decisions about
  the acceptable use of the water resource was to
  create a plan that considered all demands on the
  water resource. Such a planning must involve all
  stakeholders in the river basin landowners,
  municipalities and their water and waste water
  treatment plants, industries, hydro power plants,
  organisations of different kind etc and
  consider all demands for the future. Of course a
  good water status must be in focus but also
  variety in quantity. To achieve these goals a
  Water Advise Unit will be settled as responsible
  for the vision plan and the contacts with The
  Water Authority.
• Important experiences
• The organisation for the planning of the water
  resource according to the EU Framework is shown
  in this illustration. Taking initiatives the
  stakeholders of the river basin will fulfil
  demands from EU but will also have the
  possibility to influence on decisions about the
  water resource.

Constructed WetlandReference project Kalmar
Dämme

• Background
• The water in the river Törnebybäcken is polluted
  by urea from the airport of Kalmar and storm
  water from industrial areas of the city Kalmar.
  The environmental demands on the airport mean
  that they have to purify the water especially for
  the load of nitrogen. To solve the problem was
  decides to design a constructed wetland.
• The project
• The project started with a pre study and an
  approval according to the environmental laws of
  Sweden. This approval was accepted and detailed
  design was followed by construction work. The
  organization and the financing of the project
  were shared by the airport of Kalmar and Kalmar
  Municipality. The monitoring program has shown
  that the nitrogen load has been decreased by
  1080 percent during the running period of 10
  years. Some possible adjustments have been
  findings from research in the wetland.

Systems Analysis Wastewater and Biowaste in
Gothenburg, Sweden

• Project
• The objective was to develop support for
  decisions on the future sustainable management of
  wastewater and biowaste in the Göteborg region.
  Eight system alternatives were studied within a
  time frame from now to the year 2050 with five
  criteria for sustainability based on the Urban
  Water Framework Hygiene, Environment (divided
  into Emissions and use of Resources), Economy,
  Socio-cultural and Technical function.
• Conclusions
• Considerable differences between the studied
  alternatives when single indicators were
  considered, but small with multicritera analysis.
• No indication to abandon the centralised system
  of today.
• Using wastewater sludge or to extract a pure
  phosphorus product at the treatment plant are the
  most sustainable ways to return phosphorus to
  agriculture.
• If more than 1530 of the nitrogen is to be
  returned in wastewater and biowaste, this will
  require too much energy.
• Considerably more nutrients in the wastewater
  than in the biowaste. It is more sustainable to
  digest biowaste than to compost it.
• It will always pay off to reduce the pollutant
  sources in the society.

Pilot plant for sewage treatment experiments
Hammarby Sjöstad, Stockholm

• Problem
• Sewage treatment methods are normally well
  established. However, changes in effluent
  demands, hydraulic or organic load or changing
  prices for energy, chemicals or sludge handling
  can demand changes in technology. New processes
  or combinations of unit operations or alternative
  equipment should be tested in smaller scale
  before investment in full scale.
• Solution
• An advanced pilot scale equipment was constructed
  in 20022003 by Stockholm Water Ltd. The direct
  purpose was to compare different methods to treat
  a relatively concentrated sewage from a new city
  area that was built to approach sustainability,
  Hammarby Sjöstad.
• The aim was to reach strict effluent limits and
  possibly also get nutrients in forms that could
  be accepted by farmers. After four years of
  testing the equipment was in 2008 handed over to
  IVL and KTH for further testing of systems and
  components
• There are now two aerobic and two anaerobic
  complete lines (including sludge treatment and
  membrane technology) that can be greatly modified
  for different purposes, and used by researchers
  and companies.

Drinking Water SupplyWater Treatment Plant
Lofsdalens vattenverk

• Background
• Härjedalen in Sweden is well known for its
  beautiful surroundings. The area is not heavily
  populated most of the year but during the winter
  season the sleepy villages becomes ski paradise
  for ski yearning people coming. Heavy variations
  as far as number of drinking water consumers are
  concerned and long distances between the existing
  water purification plants has challenged the
  authorities responsible for the drinking water
  supply.
• The project
• Surface water is used as raw water for production
  of drinking water at Lofsdalens water
  purification plant. The surface water is
  contaminated with organics and humic acids which
  made it unsuitable for drinking without water
  treatment. The demands as far as drinking water
  consumption is concerned vary during the year,
  the spectra is between 100-700 m3/day. In the
  past the solution was flocculation and filtration
  with chemicals. With the variation in flow and
  low temperatures of the water at winter time the
  plant needed a lot of manual attendance for
  regulating the chemical addition. The maintenance
  people from the main city was located 100 km from
  the plant and the travel costs was big with
  several visits a week to the plant.
• A complete NF plant, delivered by HOH
  Vattenteknik AB became the solution for cost
  efficiency. The plant is totally automatized and
  the steering and control of the plant can be made
  from a central control room in the main city
  which saves money and environment due to long
  distances in the area.
• Reflections
• The plant has been operating as originally
  planned for over 10 years. In order to save both
  economical and environmental recourses solutions
  with low maintenance needs must be taken into
  consideration. According to roomers the skiers in
  Härjedalen enjoy their drinking water just as
  much as their skiing, in other words- we are
  satisfied!

Drinking Water SupplyUppsala water treatment
plants
Background The Uppsala ridge is one of Swedens
largest ground water basins. The soil, which is
rich in lime, makes the water very hard. The hard
water dissolves copper from copper pipes in
buildings, which will cause problems. In the two
new water treatment plants, Bäcklösa and Gränby,
the water is treated before distribution. The
project Uppsala municipality awarded Malmberg the
contract to design, deliver and install all
mechanical equipment, stainless steel pipes,
fittings and instruments to both of the new water
treatment plants. The process is almost
identical for both plants and consists of the
following steps Aeration Aeration is done in
two parallel connected staircase aerators for
aeration and evaporation of carbon dioxide.
Water softening The water will be softened in
fluidized sand beds, where the hard raw water
will be pumped into the bottom of the five 11
meters high reactors. The upward flow lifts the
grit, and the bed is fluidized. By adding lye,
the pH value will increase and the lime will
deposit on the grit, which makes the grit
particles grow and settle to the bottom. A
fraction of the raw water bypasses the reactors.
It is mixed with softened water to receive the
desired degree of hardness. Filtration
Filtration is done in six two-media filters in
each plant. For backwashing the filters, there
are flush pumps and aerators for combined
air/water flushing. Bäcklösa WTP has also been
equipped with ten carbon filters for further
treatment. Important experiences After start up
of the two plants, the city today has a drinking
water of high quality that fulfills all
requirements and needs.

Capacity Building on Cleaner Production
Hyderabad Region, India

• Background
• The cost of environmental damage is estimated to
  be over 5 of Indias GDP. India currently
  generates over 110,000 million litres of
  wastewater a day, and over 12,000 tonnes of
  hazardous waste. Untreated wastewater places
  increased stress on existing water supply. With
  an industrial production growth rate of 7.4 per
  year, waste generation is set to exponentially
  increase in the next 20 years. Proper treatment
  and discharge of industrial waste is an immediate
  need.
• The untreated effluent of most companies will not
  fulfil the requirements that should be set by the
  common effluent treatment plant. Therefore a
  pre-treatment is needed.
• The project
• The concept of cleaner production and
  resource-efficiency is very useful for
  implementing a pre-treatment, but also for
  process optimisation. In general, the concept
  implies to treat effluents where they are
  generated, and try to recycle valuable resources
  like chemicals, water and energy. Also hazardous
  substances and substances that might harm
  treatment processes at a common treatment plant
  can be prevented from leaving the factory in
  harmful concentrations.
• This three year project shows how to implement
  solutions for cleaner production in different
  Indian industries and address cleaner production
  as a tool for efficient treatment of industrial
  emissions and effluents. The project will
  demonstrate how cleaner production can contribute
  to an improved environmental situation and
  sustainable water use, in combination with
  economical savings for the industries. It will
  also establish contacts with Swedish technology
  suppliers with interesting cleaner production
  solutions.

plant

• Background
• Ellinge WWTP serves the community of Eslöv and
  the Procordia Food production plant. Depending on
  the season, the load varies from approximately
  25,000 p.e. to 100,000 p.e. This calls for a
  highly flexible treatment process.
• The project
• During 2005-2006 Malmberg made, on a total
  contract, a comprehensive reconstruction and
  expansion for improved biological reduction of
  nitrogen and sludge treatment. The contract
  included site preparation, building construction,
  machinery and sanitation installations, and
  electrical installation and automatic control
  equipment. Malmberg also carried out the project
  planning, design, installation, commissioning,
  fine tuning and testing for this turn-key
  contract. The two old trickling filters were
  converted into basins where the return sludge is
  fed to Procordias pretreated waste-water and
  reject water. The activated sludge basins were
  modified, internal pumping of water from
  Procordia was built, and new pipes and blowers
  were installed. The whole sludge treatment area
  was reconstructed, including new pipes and new
  receiving stations for external sludge from the
  municipality and industry. A sludge silo was
  erected for the collection and mixing of all
  sludge streams before digestion, and a mechanical
  thickening step was added. A great number of new
  pumps were mounted, e.g. pumps for primary and
  return sludge. A sampling room was also built.
  numerous rebuilding measures were also made
  throughout the treatment plant. The contract was
  carried out in an atmosphere of excellent
  co-operation with Eslöv Municipality, as well
  process personnel at Ellinge WWTP.
• Reflections
• There has been a thorough analysis of treatment
  results from the two years following start up,
  evidence that the chosen technology works to full
  satisfaction.

Bio Gas Green Gas concept of BiogasKönnern
Biogas upgrading plant

• Background
• The Biogas Plant Könnern in Germany was planned
  to produce biogas from green gas products and
  then to be burnt in gas engines (CHPs). According
  to Malmbergs customer, this was in the beginning
  of the project the best solution according to the
  subvention guidelines, EEG. A new version of the
  subvention was launched and a technical bonus was
  added so that upgraded biogas by Malmberg was the
  most profitable solution.
• The project
• Malmberg Biogas got in April 2007 an order to
  deliver the biggest biogas upgrading plant in
  Germany, also the biggest one in the world to
  produce clean methane to the natural gas grid
  from green products. The plant is based on the
  principle of a water scrubber and Malmberg
  Technologies in the field of upgrading biogas had
  then been focusing on the best solution for
  optimizing the upgrading plant together with the
  production plant. So that biogas in the total
  values chain could be produced to the lowest
  cost.
• The scope of delivery was an upgrading plant
  including injection station to the natural gas
  grid the delivery time was set to inject gas at
  20 December 2007 in Könnern. The upgraded biogas
  should be distributed by the gas company MITGAS
  (owners RWE), and to be sold as a new product
  launched as MitBioGas, both private and
  commercial purpose. The profit for the customer
  was to sell green gas at the same cost as for
  fossil natural gas.

Bio Gas Green Gas concept of BiogasKönnern
Biogas upgrading plant

• Important experience
• In the past the traditional way of using biogas
  in Germany was to inject electricity direct to
  the electric grid at the biogas production plant.
  
• With Malmberg Biogas the customer has found a new
  way through the natural gas grid the customer
  can higher the efficiency in total by injecting
  the electricity in other locations and then make
  use of the heat losses, which today stands for
  2/3 of the input to the gas engine. Heat resource
  by biogas plants was in the past seen as a
  surplus, today must the total energy demand be
  optimized.
• New heat solutions are implemented for a total
  decreasing of the energy demand. Energy from
  biogas will therefore only allow heat from green
  energy, which has resulted in that products with
  low heat demand, both in production and
  upgrading, will be the most optimal ones.

Bio Gas Energy ProductionSkellefteå Biogas
Plant

• Background
• The municipal biogas plant, situated at Tuvans
  wastewater treatment plant in Skellefteå,
  receives domestic waste, slaughterhouse waste and
  liquid waste
• The project
• The plant has three receiving units, of which two
  are for source-separated domestic waste and one
  for slaughterhouse waste.
• The units for domestic waste are equipped with
  four bottom screw conveyors each for
  decomposition and homogenisation of the incoming
  substrates and discharge to the transport
  conveyors for further transport to two mixers. In
  the mixers, the substrate is diluted to the right
  DS concentration. From the mixers, the substrate
  is led to a bio-separator for separation of
  non-digestable material. After that, the
  substrate passes through a disperser for further
  decomposition and is then led to the buffer
  tanks.
• The slaughterhouse waste is transported with a
  bottom screw conveyor to the disperser for
  decomposition and from there to the buffer tanks.
  
• Liquid waste is pumped to the buffer tanks via
  the disperser.
• From the buffer tanks the substrate is pumped to
  two hygienisation tanks where the substrate is
  heat-treated at 70 C before it is pumped to the
  digester. To avoid too high temperature in the
  digester, the incoming substrate is cooled with
  the dilution water flow that is recycled to the
  process.
• The produced biogas is then upgraded to vehicle
  fuel.

Bio Gas Energy production Himmerfjärdens waste
water treatment plan

• Background
• Himmerfjärdens waste water treatment plant south
  of Stockholm has a load of 300.000 pe. Major
  energy consumption is found in the inlet pumping
  station biological treatment with full
  nitrification Sludge is digested and a large
  portion of the biogas is flared. A sharp
  increase in electricity cost triggered an energy
  conservation project to reduce opex.
• The project
• An energy survey with sensitivity analyses was
  undertaken in co-operation with experts from
  university and consultants. The project was
  initiated by Himmerfjärdens WWTP who financed the
  studies that resulted in significant energy
  savings and several projects being implemented,
  e.g. refurbishment of inlet pumps (energy savings
  of 23 percent), improved thickening before
  digestion, (lower heating cost and higher biogas
  production), a new gas engine connected to a
  blower, reduce electrical energy consumption with
  350 kW, upgrading biogas to vehicle fuel creating
  a revenue, calculated payback within 3 years.
• Important experiences
• Based on a thorough evaluation and sensitivity
  analyses significant energy savings and optimized
  usage of biogas, heat and electricity can be
  reached

  Offer, was to a larger extent promote the Swedish
  model for integrated water and wastewater
  management abroad. Behind the initiative are the
  internationally most well merited and experienced
  private and public water management corporations
  of Sweden.
• SymbioCity CleanWater Offer is organised as a
  consortium and is managed by the Swedish
  Environmental Technology Council, Swentec. The
  consortium which constitutes of more than 50
  members includes all the resources necessary for
  long and prosperous bilateral collaborations,
  involving the Swedish private sector,
  municipalities, research institutions, funding
  and Swedish governmental institutions.

The Swedish knowledgebase

• Nothing has greater impact on our lives than
  water. Water is fundamental for our health,
  comfort and prosperity. We believed water to be
  an endless resource, and nature would take care
  of any irresponsible misuse. Today, we know
  better. We know that careless water usage will
  cause a great environmental impact.
• Members of the SymbioCity CleanWater Offer have
  worked with water management for over 140 years.
  Export started 1903 with a sewage plan for St.
  Petersburg, Russia. In the early days focus was
  on providing freshwater and fire fighting,
  thereafter sanitation by sewage treatment.
• Since the 1960s the environmental aspects have
  been the focus for Sweden, with a major
  construction period of wastewater treatment
  plants in the 60s and 70s. This has resulted in
  what might be the most far-reaching effluent
  standards in the world being enforced in Sweden.
  The water issue is ever evolving. Today the
  SymbioCity CleanWater Offer focus on integrated
  wastewater and water management, which optimizes
  water and energy resources from a broader
  perspective including environmental, social and
  economical effects, reaching from a whole region
  to a single plant.
• The development in Sweden has given the
  CleanWater members an extensive experience and
  knowledgebase. Only in Sweden, the CleanWater
  members have designed, constructed, serviced and
  maintained more than 4000 public wastewater and
  water treatment plants and approximately 30
  meters of piping per capita to handle the
  infrastructure. This knowledge and experience has
  been exported throughout the globe, to more than
  100 countries and 10 000 projects!
