Mechanical treatment of fish and other aquatic ponds is the only possible way to separate waste and uneaten food, which is done by DRUM FILTERS steel filter drum model H2. Currently, almost all fish farms that operate with limited water treat the outlet water of the ponds with filter drums that have nets with springs of 40 to 100 microns. Due to limited water supply in many parts of the country, the use of filter drums is an advantage. Also, water quality management is much easier in terms of heating or cooling and hygienic control of water in this type of farms. Low-water aquaculture is much more environmentally friendly for commercial fish production, and water-soluble waste is the best fertilizer for agriculture. Solid aquatic discharges in farming ponds should be directed to the mechanical filter in the shortest time possible (water circulation dynamics play an important role in the pond) and without breaking. Because the more solid the masses, the higher the harvest. For example, on a 30-ton fish farm, which uses a mechanical filter (filter drum) with a yield of 50 percent, it produces 75 tons of sludge during the growing season, including 85 percent moisture. Steel filter drums are produced in 3 series with drum diameters of 80, 120 and 160 cm, with a maximum treatment capacity of 750 liters per second. The drum filters are all made of 304 or 316 stainless steel and are available in three forms: framed, tubular and tank. All parts of the filter drum (chassis, drum, mesh net and mesh support) are made of stainless steel (steel 304 or 316). All drama filters of Abzi Gostar Green Company have a 2-year warranty.
