Shandong High Efficiency Filter: The most commonly used method for sewage treatment by mechanical filtration. According to the different filtration media, the mechanical filtration equipment can be divided into two categories: granular media filtration and fiber filtration. The granular media filtration mainly uses granular media such as sand and gravel as filtration media, through the adsorption of granular media and the suspension of solid in the pore between sand particles. The advantages of substance interception for filtration are easy backwash, but the disadvantages are slow filtration speed, generally not more than 7m/h; less sewage interception, the core filter only has the surface of the filter layer; low filtration accuracy, only 20-40um, which is not suitable for rapid filtration of wastewater containing high turbidity.
High efficiency asymmetric fiber filter system uses asymmetric fiber bundle material as filter material. Its filter material is asymmetric fiber. On the basis of fiber bundle filter material, a core is added to make it have the advantages of both fiber filter material and granular filter material. Because of the special structure of filter material, the porosity of the filter bed quickly forms gradient density up and down, which makes the filtration process easier. The filter has the advantages of fast filtration speed, large contamination interception and easy backwashing. Through special design, the process of adding medicine, mixing, flocculation and filtration can be carried out in a reactor. The equipment can effectively remove suspended organic matter in aquaculture water, reduce COD, ammonia nitrogen and nitrite in aquaculture water, and is especially suitable for the filtration of solid suspended matter in circulating water of temporary culture pond.
