Equalization meaning in wastewater treatment

In many water treatment systems, it is useful to implement flow equalization downstream of the plant, because the downstream demand is not steady, but in general, the treatment processes work more efficiently if the flow rate through them is steady. In treating wastewater, the rate at which the waste arrives at th Flow equalization is the process of controlling hydraulic velocity, or flow rate, through a wastewater treatment system. The equalization of flow prevents short term, high volumes of incoming flow, called surges, from forcing solids and organic material out of the treatment process The primary objective of flow-equalization basins for municipal wastewater plants is simply to dampen the diurnal flow variation, and thus achieve a constant or nearly constant flow rate through the downstream treatment processes

Generally speaking, flow equalization is not a treatment process or treatment method; it's a method to improve wastewater treatment processes, whether they are physicochemical processes or biological processes EPA-600/2-79-096 May 1979 EVALUATION OF FLOW EQUALIZATION IN MUNICIPAL WASTEWATER TREATMENT by J.

Preliminary Treatment of WasteWater by Screening, Grit

Wastewater treatment process occurs via several major steps such as preliminary treatment, primary treatment, secondary or biological treatment, tertiary treatment and anaerobic digestion. Biological wastewater treatment is the key step in the wastewater treatment process, and it is carried out by organisms such as microorganisms, nematodes. Membrane bioreactor (MBR) is a wastewater treatment system that combines a membrane process with a suspended growth biological treatment method. Typically, the membrane is either low-pressure microfiltration or ultrafiltration, and the suspended growth step is an activated sludge process It is a modification of a dual-lagoon system. Wastewater flow travels through screening and then into the treatment system. During high flow periods, the old primary lagoon can be used as an equalization basin. After primary treatment, flow goes through two circular clarifiers (30) Equalization basin--A treatment unit designed primarily to dampen fluctuations of flow or concentration before wastewater flows into a subsequent treatment unit.
