Collection tank: Collect all the wastewater on the channel leading to the treatment system.
Conditioning tank: Stabilize flow, contaminant concentration, pH. Preliminary ventilation to avoid anaerobic decomposition causing odors.
Aerobic tank: The amount of gas supplied to the device for the purposes of: (1) providing oxygen for aerobic microorganisms to convert dissolved organic matter into water and carbon dioxide, organic nitrogen and ammonia into nitrate NO3-, (2 ) evenly mix wastewater and activated sludge to create favorable conditions for microorganisms to come into good contact with the substrates to be treated, (3) release gases that inhibit the microbial life process, These gases are generated. in the process of microorganisms breaking down pollutants,
(4) positively affects the reproduction process of microorganisms.
MBR Membrane: Enhanced air is brought in by an air supply through the piping systems at the bottom of the module, ensuring an adequate supply of oxygen for microbial life to decompose organic compounds in wastewater. .
Disinfection tank: Contact with Chlorine to completely destroy Coliforms and other disease-causing germs, the treated water meets discharge standards into the receiving source.
