One common process in wastewater treatment is phase separation, such as sedimentation. Biological and chemical processes such as oxidation are another example. Polishing is also an example. The main by-product from wastewater treatment plants is a type of sludge that is usually treated in the same or another wastewater treatment plant. [2]:
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 .
In Thailand, the total volume of the wastewater from industries is much greater than that of the domestic sewage. [2] As a result, an effective method is needed. Microbial remediation of xenobiotics has shown to be effective and the low-cost technology, but it still has several limitations.
This is why low speed surface aerators are mostly used in sewage or industrial treatment as WWTP [clarification needed] are bigger and sparing energy becomes very interesting. Biological oxidation processes are sensitive to temperature and, between 0 °C and 40 °C, the rate of biological reactions increase with temperature.
The RBC process allows the wastewater to come in contact with a biological film in order to remove pollutants in the wastewater before discharge of the treated wastewater to the environment, usually a body of water (river, lake or ocean). A rotating biological contactor is a type of secondary (biological) treatment process.
English: This diagram depicts the process and benefits of sewage treatment. Sewage treatment helps to protect the environment and all organisms as this process aims to remove contaminants such as bacteria, nutrients, pathogens and any other chemicals that may contaminate surface waters.
