Wastewater Treatment Career Guide and Counseling

Question: wastewater treatment? what is the basic type of wastewater treatment?

Answer: Where waste goes to a WWTP, it gets screened to remove the big pieces (towels, branches, alligators...). Then grit is allowed to settle out and the foam is skimmed. This primary sludge is landfilled. A few old plants stop here and discharge the sewage to a stream. Most plants go on to secondary treatment, allowing bacteria to attack the organic matter. Usually, this involves spraying the sewage onto rocks or pieces of plastic on which the bacteria live. Then the sewage, now lower in biological oxygen demand, is released to a stream. All too few plants have tertiary treatment, designed to reduce the nutrients (P & N) in the sewage before discharge.Sludge from each stage is landfilled; water is discharged to a stream or wetland. A septic system is usually just secondary treatment for a single building.
