• It is unrealistic to assume that a community can
  completely prevent waste generation or recycle
  all the waste in its program
• There will always be the need for treatment and
  disposal of waste

Description

• Waste management program
• waste characterization
• Program development
• financing waste management

Continue- waste characterization

• Waste characterization means what types of waste
  are generated, what quantities and how much can
  realistic be prevented through source reduction
  and collected for recycling
• Source reduction and landfill projects require
  only gross waste volumes for estimates
• Recycling and waste to energy projects require
  accurate prediction of waste quantities and
  composition

6
Continue-waste characterization

• Different techniques
• Modeling techniques
• Physical separation techniques
• Direct measurement techniques

7
Program development-crucial items

• Formulating and following a well devised and
  comprehensive plan
• Basing decisions on sound economic analysis
• Keeping public participation rates high over a
  number of years based on a ongoing education and
  publicity plan
• Acquiring and maintaining continuous political
  support for the program
• Developing the program having a long term vision
  covering all stage of its life

• Significant commitment alternative methods to
  finance program
• Tipping fees at publicity owned of financed
  facilities at non competitive prices
• Taxes
• User fees or surcharges

• Basis for involvement of private sector in the
  provision of waste management services in
  developing countries-sound economic analysis is a
  requirement to ensure a sustainable financing
  schemes for waste management programs

Waste water treatment

• Treatment technologies and verification systems
  used to evaluate the systems operational
  efficiency
• From verification and regulation perspectives
  waste water treatment technologies are defined as
  the available treatment systems that are used for
  decentralized treatment of domestic ,commercial
  or industrial waste water

11
continue

• Technology will provide total treatment of waste
  water, rendering it suitable for disposal to a
  particular environment
• Some technologies may require some form of pre
  treatment e.g. screening ,pH correction or post
  treatment e.g.disinfection

12

• Waste water treatment can be
• Biological
• Physical
• Physical-chemical or
• combination

13
A waste water treatment system

• Schematic of technology, showing all major
  components, including any pre-treatment process
• Engineering and scientific concepts of waste
  water treatment equipment
• Full description of each unit process along with
  relevant photographic perspectives or schematics
• Equipment capacity and dimension
• Physical construction/components of equipment
  included material of construction

14
continue

• General environmental requirements and
  limitations
• Required consumables
• A description of the application of technology,
  the flow and load capacity and the expected
  removal capabilities of the technology
• An estimate of the operation an management
  requirements, included chemicals and materials
  requirements, power and labor requirements

15
continue

• Instructions on installation ,start up,
  operation, routine maintenance and trouble
  shouting
• Environmental controls (e.g. nutrient supply ,pH
  control, dissolved oxygen level, biomass
  concentration etc)
• A description of the physical an chemical nature
  of waste generated by the technology and the rate
  of waste produced (e.g. concentrates ,residues,
  waste products, material replacement frequencies)
• Requirements and /or recommendation for residual
  handling
