We provide communities with scientifically proven and environmentally sound solutions for collection, treatment and release. Introduction to Waste Water Treatment: ADVERTISEMENTS: The composition of municipal waste water varies from place to place. The major aim of wastewater treatment is to remove as much of the suspended solids as possible before the remaining water, called effluent, is discharged back to the environment. To check these systems, smoke is released into the pipes to check the condition of the pipes, like for a leak or a broken pipe. 2. Secondary Treatment The secondary stage of treatment removes about 85 percent of the organic matter in sewage by making use of the bacteria in it. Respirometry System for Biomass Activity Testing; .
