Media Expansion Monitoring Improves Filter Performance ...
A 20 mgd Ohio plant uses the instrument for direct process control by varying its wash water rate to secure the desired amount of expansion rather than using a stipulated rate of flow. One plant recently identified a faulty backwash pump check valve and another found a faulty flow meter by observing unexpected reductions in expansion.
Sand Washing Plants. McLanahan Sand Washing Plants process sand from its raw state into products that meet various specifications. The process requirements vary depending on the input and desired output, but plants typically scrub, liberate, deslime, wash, classify, decontaminate and dewater the sand, as well as process the effluent stream that ...
Slow Sand Filtration - an overview | ScienceDirect Topics
The filtration rate is from 0.08 to 0.4 m/h. In the usual operating mode, influent water is introduced above the filter bed in a way that does not disturb the sand (Edzwald, 2011). In Europe, slow sand filtration is used in facilities supplying drinking water to large communities such as in London and Amsterdam (Crittenden et al., 2005).

Sand Filtration by means of a sandfilter. Depending on the type of water, suspended solids concentration, oil and grease, COD/ BOD, iron contents, sand filters are sized differently, but the basic design data to clarify natural waters are the following:
Backwash Water - an overview | ScienceDirect Topics
Spent filter backwash water. Filtration practices employed in water treatment plants produce large volume of wash water containing a low concentration of suspended solids, ranging from 30 to 400 mg/l, depending on the turbidity of the treated raw water and the amount of recycled backwash water.The backwash water volume is usually 2-3% of the treatment plant flow.
