Wastewater Industry Solutions - Complete And Reliable Liquid Analysis
Years ago, sewage was treated by simply dumping it into waterways. The purification process was accomplished by microorganisms consuming sewage and turning it into carbon dioxide and other products. Dilution was on our side, but today, due to higher population and greater volume of both domestic and industrial wastewater, nature needs a helping hand. This is where wastewater treatment comes in.
Typically, wastewater treatment includes four basic treatment stages: primary, secondary, sludge and final treatment. In the primary treatment stage, larger solids are removed from wastewater by screening and settling. Secondary treatment is a large biological process for further removal of the remaining suspended and dissolved solids. Sludge is generated during the first two stages and is treated to convert it into a stable organic solid. In the final treatment, wastewater is disinfected to kill any remaining harmful microorganisms prior to being released.
