SUBSTANCE: method of purification lies in running water through layer of granular charge until latter is contaminated, stopping filtration process, supplying air and/or washing water towards widening of granular charge layer until it is washed from contamination, mixing reagents and/or sorbents with washing water, supplying said mixture to widened layer of grain charge until its main part is filled with mixture, stopping supply of washing water

Drinking Water Purification: Water is purified for drinking through a system of filters and by chemical disinfectant. Pumping and Containment: Water is pumped from the source into holding tanks. Screening: Water is passed through a screen filter to remove large debris. Storage: Water is stored in reservoirs, tanks, and water towers in ...

Sand wash water filter. This works more like a bag filter although it can handle more solids at a higher flow rate. It is ideal for removing solid particles from wastewater by straining them from the treatment stream. The water is pumped on sand filter vessel and as the solids laden, the water trickles through the sand.

2021-3-22 The entire wastewater purification process can (thanks to the now absent fine sand particles) then be carried out in a way that very much protects the components and results in very low wear and tear. Therefore, constructors of wastewater treatment plants generally aim to have as little sand

Car wash wastewater treatment and water reuse - a case study. Recent features of a car wash wastewater reclamation system and results from a full-scale car wash wastewater treatment and recycling process are reported. This upcoming technology comprises a new flocculation-column flotation process, sand filtration, and a final chlorination.

1999-4-22 Waste water 21 is pumped through the moving bed granular filter 22 and purified. The wash water, containing the metal loaded biomass, is drained to a lamella separator 23. The water, coming from the lamella separator, is reintroduced in the sand filter (24). The sludge (wash water+metal laden biomass), is, possibly after dewatering, preferably recycled in a pyrometallurgic treatment facility.

2021-6-15 Wash Sand Filter. The passage of suspended particles in the water over time causes a large volume of them to be placed on the body of sand and silica on the nozzle and reduce the quality of the output water. For this purpose and like other water purification methods, it is necessary to wash the device periodically.
