Solids such as stones, grit, and sand may be removed from wastewater by gravity when density differences are sufficient to overcome dispersion by turbulence. This is typically achieved using a grit channel designed to produce an optimum flow rate that allows grit to settle and other less-dense solids to be carried forward to the next 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.
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.

The plant includes six fine screens to remove large objects from wastewater flowing into the plant, which then makes its way into grit removal basins to settle out sand and other particles; debris removed from the wastewater are taken to the Quarantine Road Landfill in south Baltimore.
Secondary treatment (mostly biological wastewater treatment) is the removal of biodegradable organic matter (in solution or suspension) from sewage or similar kinds of wastewater. [ 1 ] : 11 The aim is to achieve a certain degree of effluent quality in a sewage treatment plant suitable for the intended disposal or reuse option.

Sand filters are used in various sectors and processes, where far-reaching removal of suspended matter from water or wastewater is required. Sectors where sand filtration is implemented include drinking water production, swimming pools, car washes, groundwater treatment, RWZI, slaughterhouses, fruit and vegetable processing industry, drinks ...
