Hazardous Liquid Waste Treatment

Hazardous Liquid Waste Treatment Total solution
2
Problem definition High levels of toxicity in
the lagoons and considerable generation of gasses
to the atmosphere, about which the Ministry of
the Environment has expressed concern. Because
the margins for error are high for employing
conventional solutions, in our view the off-
gasses that are being generated within the sludge
are then further exacerbated by the toxicity of
the water producing the current effects.
Solution Our recommendation offers a total
solution. Environmental concerns are high on the
global agenda and it addresses all the
environmental issues.

Recommendation

• A.     Temporarily treat the off-gases at the gas
  phase
• B.     Manage the effluent outflow from the plant
  as part of
• the program
• C.     Remove and treat all stored sludge and
  water
• D.     Create an effluent treatment system that
  will meet current
• legislation and future legislational
  changes. Create an
• industry standard with no future legacy.
• E.     Give added value - through recycling the
  water,
• generating electricity and selling spare
  capacity
• F.      Significantly reduce the current
  footprint
• Return the land to nature or agriculture /
  horticulture

Hazardous Liquid Waste Treatment Plant

• A Development of Various Integrated Technologies,
  Based on Thermal Treatment of Polluted Liquids,
  by Utilization of Microwave Driven Plasma Torch
  Technology.

What is Plasma?
10
What is Plasma?

• Plasma is an ionized gas, the change to plasma
  phase occurs when the ions are separated from the
  electrons and try desperately to renew the
  connection.
• The temperatures of material in the plasma phase
  range from 500 to 100.000ºc.
• On earth, the plasma phase does not exist in
  natural form (except phenomena such as
  lightning), but in the universe, more than 97 of
  all materials are in the plasma phase (sun and
  stars).

11
High Powered Plasma Torch
Utilization of Off the shelf technologies by
installing a compact microwave driven plasma
torch enables thermal treatment of all kinds of
waste liquids. This system uses high pulsed
microwave, in order to produce an uninterrupted
plasma plume under atmospheric conditions. The
Plasma Torch has an extreme high efficiency rate,
which makes it economic and environmentally
friendly in use.
12
How Does the Plasma Torch Operate?

• With the help of a microwave resonator, micro
  wave power waves are pulsed through a gas flow
  (in this case air).
• The friction between gas and power forces the
  ions out their path around the electron.
• The agitated flow of ions cause extreme high
  temperatures (heat without combustion) ranging
  from 500 till 100.000ºc.
• The flame-like plume after leaving the torch
  housing is a non extinguishing super-heated
  region, with determinate length and diameter.

The Principles of Thermal Treatment

• The to-be treated liquids are forced through the
  super-heated plasma plume, in this case with
  temperatures around the 5.500ºc.
• The water contents (approx. 99 of the total) of
  the liquid will evaporate and rise in the reactor
  when reaching the temperature of 100ºC. The
  change from water into water vapour will take
  less than a second.
• The organic and acid materials in the liquid will
  continue to heat up in the plume, until it
  reaches the stage of gasification. Organic and
  acid gasses are heavier than air, causing them to
  descent in the reactor.
• The remaining an-organic matter will fluidize at
  high temperatures, and as they are also heavier
  than air, they will fall into the water reservoir
  at the bottom of the reactor.

18
Temperatures Required for Change of Phase.

• From water to water vapour - 100ºC
• Organic residue to gas from 700 to 2,000ºC
• Liquidizing inorganic materials up to 1.200ºc

19
The Vapour Path

• The steam (water vapour) rise upwards in the
  reactor, and leave through an one way escape
  valve into a steam pressure chamber.
• The high pressured steam is flown into a turbine,
  which powers an electric generator, producing
  electricity power.
• By turning the turbine heat is lost and water
  vapour returns to its original liquid phase
  water.

Facts on Water / Steam Quantities

• 5 cubic meters of water 5,000 kg steam.
• Water converted into steam will expend approx.
  1,600 times in volume.
• A plant treating 5 cubic/meters per hour is
  capable in producing 1,250 kilo watt electricity
  (according experts at Ormat).
• In the picture below, a steam drying plant with a
  discharge of 3.5 cubic/meters/hour.

Distilled and Drinking Quality Water

• The water produced from steam is distilled water,
  which does not contain any material dangerous for
  human consumption.
• Distilled water is dead, without any kind of
  structure and containing none of the essential
  minerals and trace elements to make it living
  water.

23
Water Energizing and Mineralizing
Structured water is essential for all living
organisms. This is especially true for the human
body, but also the soil and any body of
water. The scientific evidence and the wide
interest in the quality of water in the last 20
years has resulted in the development true
energizing systems. The process is rapid, and it
is now possible to truly have structured,
alkaline, mineralized and energized water on a
large scale
