2. Anaerobic digestion - Wikipedia

   en.wikipedia.org/wiki/Anaerobic_digestion

   Anaerobic digestion is particularly suited to organic material, and is commonly used for industrial effluent, wastewater and sewage sludge treatment. [77] Anaerobic digestion, a simple process, can greatly reduce the amount of organic matter which might otherwise be destined to be dumped at sea, [ 78 ] dumped in landfills , or burnt in ...

3. Waste stabilization pond - Wikipedia

   en.wikipedia.org/wiki/Waste_stabilization_pond

   In the treatment of sewage, systems composed of anaerobic ponds followed by facultative ponds usually have overall BOD removal efficiencies between 75 and 85%. Higher efficiencies are difficult to achieve because the effluent contains high concentrations of particulate organic matter, in the form of algae, naturally produced during treatment.

4. Septic tank - Wikipedia

   en.wikipedia.org/wiki/Septic_tank

   The term "septic" refers to the anaerobic bacterial environment that develops in the tank that decomposes or mineralizes the waste discharged into the tank. Septic tanks can be coupled with other onsite wastewater treatment units such as biofilters or aerobic systems involving artificially forced aeration. [3]

5. Anammox - Wikipedia

   en.wikipedia.org/wiki/Anammox

   Anammox, an abbreviation for "anaerobic ammonium oxidation", is a globally important microbial process of the nitrogen cycle [1] that takes place in many natural environments. The bacteria mediating this process were identified in 1999, and were a great surprise for the scientific community. [2]

6. Anammox for wastewater treatment - Wikipedia

   en.wikipedia.org/wiki/Anammox_for_wastewater...

   Treatment of wastewater to improve sanitation is a major challenge in developing countries, as untreated wastewater can contaminate drinking water. Anammox bacteria treatments have been implemented in treatment facilities to help convert sewage wastewater into sludge ash, which is then used as a fertilizer source for agriculture. [8]

7. Upflow anaerobic sludge blanket digestion - Wikipedia

   en.wikipedia.org/wiki/Upflow_anaerobic_sludge...

   Upflow anaerobic sludge blanket (UASB) technology, normally referred to as UASB reactor, is a form of anaerobic digester that is used for wastewater treatment. The UASB reactor is a methanogenic (methane-producing) digester that evolved from the anaerobic clarigester .
