Packaged Wastewater Treatment Plants

|
|
General
|
These pre-engineered, packaged systems provide the end-user with an
economical approach to treatment of wastewater by an aerobic
process. This Modular approach also provides our customers with an
efficient, compact, easy to operate, and cost effective method of
wastewater treatment. This Biological Treatment utilizes Extended
Aeration/Activated Sludge process rendering an environment with
sufficient oxygen levels and agitation to allow Bio-oxidation of contaminants
to take place, lowering the pollutants' thresholds to levels
suitable for discharge. The active Microorganisms introduced with
the Biomass, coupled with sufficient air and agitation will oxidize the
Biodegradable constituents into carbon dioxide, water and stable sludge.
Typically, these packaged plants are used for treatment of Domestic
effluents. However, they can also be utilized for treatment
of Industrial wastewater in which biodegradable
constituents are encountered. In either case, the effluent of this
treatment can be safely discharged or further treated in a polishing
loop for the purpose of Reuse
or Recycle.
