2. Decentralized wastewater system - Wikipedia

   en.wikipedia.org/wiki/Decentralized_wastewater...

   Decentralized wastewater systems (also referred to as decentralized wastewater treatment systems) convey, treat and dispose or reuse wastewater from small and low-density communities, buildings and dwellings in remote areas, individual public or private properties. [ 1] Wastewater flow is generated when appropriate water supply is available ...

3. Membrane bioreactor - Wikipedia

   en.wikipedia.org/wiki/Membrane_bioreactor

   Membrane bioreactors are combinations of membrane processes like microfiltration or ultrafiltration with a biological wastewater treatment process, the activated sludge process. These technologies are now widely used for municipal and industrial wastewater treatment. [ 1] The two basic membrane bioreactor configurations are the submerged ...

4. Advanced oxidation process - Wikipedia

   en.wikipedia.org/wiki/Advanced_oxidation_process

   Advanced oxidation process. Advanced oxidation processes ( AOPs ), in a broad sense, are a set of chemical treatment procedures designed to remove organic (and sometimes inorganic) materials in water and wastewater by oxidation through reactions with hydroxyl radicals (·OH). [ 1] In real-world applications of wastewater treatment, however ...

5. Wastewater treatment - Wikipedia

   en.wikipedia.org/wiki/Wastewater_treatment

   Wastewater treatment. 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. It is also possible to reuse it.

7. Sewage treatment - Wikipedia

   en.wikipedia.org/wiki/Sewage_treatment

   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. [ 2]

8. Activated sludge - Wikipedia

   en.wikipedia.org/wiki/Activated_sludge

   The white bubbles are due to the diffused air aeration system. The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa. It is one of several biological wastewater treatment alternatives in secondary ...

9. Industrial wastewater treatment - Wikipedia

   en.wikipedia.org/.../Industrial_wastewater_treatment

   Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater ...
