Biological wastewater treatment is designed to degrade pollutants dissolved in effluents by the action of microorganisms. The microorganisms utilize these substances to live and reproduce. Pollutants are used as nutrients.
Biological STP's
- The Moving Bed Biofilm Reactor (MBBR) is a sewage treatment plant method utilizing suspended plastic carriers to foster microbial growth, effectively eliminating organic and inorganic contaminants from wastewater.
- The Sequential Batch Reactor (SBR) is a sewage treatment plant technique designed to eliminate organic and inorganic contaminants from wastewater. It functions in batch mode, wherein various treatment stages (filling, reacting, settling, decanting) take place consecutively within a single reactor tank.
- The Membrane Bioreactor (MBR) is an advanced sewage treatment method integrating biological treatment and membrane filtration to separate treated water from suspended solids and microorganisms. MBR systems find extensive application across diverse sectors, including municipal, industrial, and decentralized wastewater treatment.
- A Rotating Biological Contactor (RBC) is a sewage treatment technology employing a rotating biological contactor for wastewater treatment. RBC systems find frequent use in small to mediumsized wastewater treatment plants and decentralized treatment facilities.
