English: This diagram depicts the process and benefits of sewage treatment. Sewage treatment helps to protect the environment and all organisms as this process aims to remove contaminants such as bacteria, nutrients, pathogens and any other chemicals that may contaminate surface waters.
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.

Combined sewer outflow into the Anacostia River in Washington, D.C. Ratcliff Beach CSO discharges into the River Thames in London [7]. These relief structures, called "storm-water regulators" (in American English - or "combined sewer overflows" in British English) are constructed in combined sewer systems to divert flows in excess of the peak design flow of the sewage treatment plant.

Process flow diagram for a sewage treatment plant with subsurface flow constructed wetlands. Constructed wetland systems can be surface flow systems with only free-floating macrophytes, floating-leaved macrophytes, or submerged macrophytes; however, typical free water surface systems are usually constructed with emergent macrophytes.

Construction of a regional sewage treatment plant to prevent effluent being pumped into the sea in the west will begin early next year. Plans for the Peel Sewage Treatment Works, situated west of ...
Sludge treatment in the sewage treatment plant of Birsfelden, Germany. Mechanical dewatering (centrifuge) at a large sewage treatment plant (Arrudas Treatment Plant, Belo Horizonte , Brazil). Water content of sludge may be reduced by centrifugation, filtration, and/or evaporation to reduce transportation costs of disposal, or to improve ...
Sewage treatment plant (a type of wastewater treatment plant) in La Crosse, Wisconsin. Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment.
A Zero Liquid Discharge (ZLD) process diagram that highlights how wastewater from an industrial process is converted to solids and treated water for reuse via a ZLD plant. Concept of ZLD Zero Liquid Discharge (ZLD) is a classification of water treatment processes intended to reduce wastewater efficiently and produce clean water that is suitable ...
