The heart of the
Wastewater Engineers, Inc. system for wastewater treatment is our clay based
Reactant Powder. When mixed with wastewater, these powders form a heavy floc,
which removes the contaminants and encapsulates them into an easily filtered
solid.
Shown here is one of our Reactant Powders and an
ink wash water that has been chemically treated. Not only does the water appear
clean, it is now sufficiently free of oils, dissolved heavy metals, and solids,
to go to sewer.
The following is a brief overview of the chemistries involved
and how they work.
Wastewater Engineers, Inc.
Reactant Powder is a clay based chemical that removes suspended solids,
emulsified oils, and dissolved heavy metals from water. When mixed in water, the
powder chemically reacts with the contaminants and forms a large floc. This
process is known as flocculation and encapsulation. The result is a sludge cake
which is suitable for disposal in non-hazardous landfills, and treated water
which is sufficiently free of oils, suspended solids, and heavy metals to be
discharged to a municipal sewer. The treated water is also an excellent
candidate for recycling, since soaps and other expensive chemicals are left
untouched during the treatment process. This allows for reuse of the water in
the production process without need to add more chemicals. After factoring in
carry-off and spillage, a realistic savings of 85% on chemical replenishment is
typically realized.
Flocculation and encapsulation
is a process of waste fixation. The Wastewater Engineers, Inc. Reactant Powder
coats coagulated droplets of oil and other contaminants with a webbing that
permanently traps the waste. The webbing forms by chemical reaction just
after flocculation. The floc starts a curing process which improves with
age.
The encapsulation process
produces a safe, non-leaching sludge that can be disposed of in non-hazardous
landfills. This type of disposal costs 3 to 5 times less than the disposal
costs of concentrates or leaching sludge in hazardous waste landfills and
eliminates the possibility of groundwater contamination. Future liability for
environmental cleanup is also eliminated. The sludge produced by the Wastewater
Engineers, Inc. treatment process is guaranteed to meet TCLP compliance for
disposal to landfills.
