'schmutzdecke' that collects in the filter. Sand removed is usually washed and returned to the filter. These filters are still in use in some small plants, especially in the western United States as well as in many developing countries. They may also be used as a final step in wastewater treatment.
Discfilters are an ideal filtration system for tertiary filtration and wastewater reuse. By employing woven cloth filter elements installed vertically on multiple discs, the Discfilter supplies a large filter area within a small footprint that is up to 75% smaller than a traditional sand or multimedia filter which means a lower total installed cost.
The DynaSand filter removes ammonia from wastewater by creating favorable conditions for treatment bacteria to flourish within the sand filter, providing a highly effective process to reduce ammonia pollution in the environment. By Kevin Marsh
Sand filters are a viable addition/alternative to conventional methods when site conditions are not conducive for proper treatment and disposal of wastewater through percolative beds/trenches. Sand filters can be used on sites that have shallow soil cover, inadequate permeability, high groundwater, and limited land area.
The performance of rapid sand filters was evaluated in three tertiary wastewater treatment plants in the State of Kuwait. These plants are located at Ardiya, Rikka and Jahra, and receive municipal wastewater flows of 220,000, 95,000 and 42,000 m 3 d −1, respectively. The Ardiya plant uses a twostage activated sludge process for the secondary treatment of wastewater whereas both the Rikka and Jahra plants .
Sand media filters are one of the oldest onsite wastewater treatment technologies known. If properly designed, constructed, operated and maintained, a sand filter produces a very high quality effluent.

Multimedia water filters typically utilize three layers of media for multimedia filtration: anthracite, sand and garnet. These media are often chosen for use in multi media filters due to the distinct differences in .
The slow sand water filter In Water Treatment field Slow sand filter is the largescale water filter. It is very old type water filtration or water treatment system. In the slow sand filter, water entering first through about 32 36 inches of sand, then through a multi size layer of gravel (This layer is known as schmutzdecke, which is German for "dirty skin.") before entering the underdrain.
The wastewater first receives primary treatment in a septic tank or an aerobic treatment unit, and then is pumped from a screened vault in the septic tank or separate dosing tank to the watertight lined sand bed or module where it is evenly distributed over the top of the sand filter bed.
