Sewage treatment is a type of wastewater treatment that aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharge.
Design aspects
• Population equivalent
• Process selection
• Odor control
• Energy requirements
• Co-treatment of industrial effluent
• Design aspects of secondary treatment processes
• Non-severed areas
SBR Sewage Water Treatment Plant (SBR-Sequencing Batch Reactor) – is an activated sludge process used for waste-water treatment. To reduce the organic matter, oxygen is bubbled through the mixture of wastewater and activated sludge.
MBR Sewage Water Treatment Plant (MBR-Membrane Bio Reactor) combines the membrane and biological waste-water treatment processes. It is one of the most widely used processes.
MBBR Sewage Water Treatment Plant (MBBR-Moving Bed Biofilm Reactor) – is a biofilm process requiring less space than activated sludge systems. This process was invented in the late 1980s.
A Sewage Treatment Plant (STP) is a facility designed to treat wastewater or sewage from residential, commercial, and industrial sources to remove pollutants and make it safe for release into the environment or reuse.
STPs are essential for protecting public health and the environment by removing harmful contaminants from sewage and preventing water pollution.
STPs use a combination of physical, biological, and chemical processes to separate and treat wastewater. This includes processes like screening, primary treatment, secondary treatment, and disinfection.
STPs remove various pollutants, including organic matter, suspended solids, pathogens (bacteria and viruses), nutrients (nitrogen and phosphorus), and potentially toxic chemicals.
Sewage treatment plants specifically treat domestic and municipal sewage, while wastewater treatment plants treat a broader range of water sources, including industrial wastewater.
