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 steel bars ...
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]
Sewage sludge treatment describes the processes used to manage and dispose of sewage sludge produced during sewage treatment. Sludge treatment is focused on reducing sludge weight and volume to reduce transportation and disposal costs, and on reducing potential health risks of disposal options. Water removal is the primary means of weight and ...
The treatment process passed wastewater through the bar screen, which filtered out large solids, then to a measuring followed by a finer bar screen flume. Solids from the bar screens went to a sludge pond, while coarsely filtered water went to a pre-sedimentation tank, which separated grease and additional solids.
Fecal sludge is defined very broadly as what accumulates in onsite sanitation technologies and specifically is not transported through a sewer.It is composed of human excreta, but also anything else that may go into an onsite containment technology, such as flushwater, cleansing materials and menstrual hygiene products, grey water (i.e. bathing or kitchen water, including fats, oils and grease ...
t. e. 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 ...
Trash rack. A trash rack (US) or debris screen is a wooden or metal structure, frequently supported by masonry, that prevents water-borne debris (such as logs, boats, animals, masses of cut waterweed, etc.) from entering the intake of a water mill, pumping station or water conveyance. This protects water wheels, penstocks, and sluice gates from ...
A traveling screen is a type of water filtration device that has a continuously moving mesh screen that is used to catch and remove debris. [1] This type of device is usually found in water intake systems for drinking water and sewage treatment plants. Screening is considered the first step in conventional sewage treatment processes.
