High-rate backwash, which expands the media by at least 10%. Backwash rates of 12-15 gpm/ft² or higher are common for sand, and rates for anthracite may range from 8 to 12 gpm/ft². Low-rate backwash, with no visible bed expansion, combined with air scouring. Where only water is used for backwash, the backwash may be preceded by surface washing.

The total backwash time of these filters is composed of several operations, but the actual time of backwash for cleaning the clogged filter bed, in terms of the time during which the backwash water flows and collected in the washwater troughs, is usually 3-8 min. Johnson and Cleasby (1966) have reported backwash duration in the range 3-12 min.

Soil Washing | Geoengineer

Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone to bind to fine grained soils (silts and ...
