Pretreatment is becoming an integral part of wastewater treatment. The Schreiber Fuzzy Filter™, with its compressible media filter, is a high rate (30+ gpm/ ft2) filter for water and wastewater solutions. The filter takes 20% of the space of most sand filters and combines advantages of a depth filter and multimedia filter with solids storage of up to 1.2 lbs/ cu. ft of media. Membrane treatment systems can benefit from removal of up to 90% of suspended solids.

Wet well washing
Anue Environmental has released the new EP-1300 series for agitating, oxygenating and cleaning pump stations, all without the use of external power or potable water. The mechanical system is a “green solution” for eliminating fat, oil, grease (FOG) and bio-film plus H2S and odors associated with bio-film in the well. Its mechanical action increases dissolved oxygen and promotes aerobic respiration. Users can expect to lower costs for well vacuuming, water cleaning and dumping of wastes. Even more savings are realized when chemicals for odor abatement are eliminated.
