Sedimentation (water treatment)
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.
A rotating biological contactor or RBC is a biological fixed-film treatment process used in the secondary treatment of wastewater following primary treatment. [1][2][3][4][5] The primary treatment process involves removal of grit, sand and coarse suspended material through a screening process, followed by settling of suspended solids.
Coagulation (water treatment)
Bar screen. A bar screen is a mechanical filter used to remove large objects, such as rags and plastics, from wastewater. [ 1] It is part of the primary filtration flow and typically is the first, or preliminary, level of filtration, being installed at the influent to a wastewater treatment plant. They typically consist of a series of vertical ...
