Clarifier / Clarification Tanks For Wastewater Treatment

Enduramaxx’s Clarifier / Clarification Tanks are used for the continuous mechanised removal of suspended solids or solid particles from a liquid. These plastic tanks, otherwise known as Conical Clarification Tanks or Clarification Cone Bottom Tanks are available in a range of sizes. Clarifier water treatment is part of the primary water treatment process.

What Is The Clarification Process?

Primary (mechanical) treatment/Clarification is designed to remove gross, suspended and floating solids from raw sewage. It includes screening or a weir to trap solid objects and sedimentation by gravity to remove suspended solids. This level is sometimes referred to as “mechanical treatment“, although chemicals see Enduramaxx chemical dosing tanks are often used to accelerate the sedimentation process.

Primary treatment through a Clarifier / Clarification Tanks can reduce the BOD (biological oxygen demand) of the incoming wastewater by 20-30% and the total suspended solids by some 50-60%. Primary treatment is usually the first stage of wastewater treatment Enduramaxx Cone tanks make ideal Primary treatment tanks. Many advanced clarifier water treatment plants in industrialised countries have started with primary treatment. They have then added other treatment stages as wastewater load has grown, as the need for treatment has increased, and as resources have become available.

Primary Treatment Through Sedimentation

Primary treatment of sewage is the removal of floating and settleable solids through sedimentation. Primary clarifiers reduce the content of suspended solids as well as the pollutant embedded in the suspended solids. Because of the large amount of reagent necessary to treat domestic wastewater, preliminary chemical coagulation and flocculation are generally not used, remaining suspended solids being reduced by following stages of the system. However, coagulation and flocculation can be used for building a compact treatment plant (also called a “package treatment plant”), or for further polishing of the treated water.

Secondary Clarifiers

Sedimentation tanks called “secondary clarifiers” remove flocs of biological growth created in some methods of secondary treatment including activated sludge, trickling filters and rotating biological contactors.
