Water to be filtered is then applied to the filter surface until the filter clogs and the backwash cycle needs to be repeated. [3]: 264–8 [4]: 10.53–10.58 [5]: 937–9 [6]: 8.11–8.18 [7]: 353–6 Some water treatment filters use surface wash systems that break up the heavily clogged, granular media surface layer.
An example of a water distribution system: a pumping station, a water tower, water mains, fire hydrants, and service lines [1] [2]. A water distribution system is a part of water supply network with components that carry potable water from a centralized treatment plant or wells to consumers to satisfy residential, commercial, industrial and fire fighting requirements.
A backflow prevention device is used to protect potable water supplies from contamination or pollution due to backflow. In water distribution systems, water is normally maintained at a significant pressure to enable water to flow from the tap, shower, or other fixture. Water pressure may fail or be reduced when a water main bursts, pipes freeze ...

Dissolved air flotation. Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.
