Mechanical filtration The most commonly used method of sewage treatment, according to the different filter media, mechanical filtration equipment is divided into two types of particulate media filtration and fiber filtration, granular media filter mainly sand and other particulate media as a filter medium, through the particulate filter adsorption and The shortcoming is that the filtering speed is slow, generally not more than 7m / h; interception of pollutants is small, the core filter layer only filter surface; filter (filter), the filter layer, Low accuracy, only 20-40μm, not suitable for high turbidity sewage with rapid filtration.
Efficient asymmetric fiber filter system using asymmetric fiber bundle material as a filter, the filter is asymmetric fibers, fiber filter media based on the addition of a nuclear, so that both the fiber filter and particulate filter media Advantages, due to the special structure of the filter, the filter bed porosity quickly formed on the large gradient density, the filter filter speed fast, large amount of interception, easy to backwash, through a special design, the dosing, Mixing, flocculation, filtration and other processes in a reactor, so that the equipment can effectively remove suspended organic matter in aquaculture water, reducing water COD, ammonia nitrogen, nitrite, etc., particularly suitable for holding water circulating solids suspended solids filter. Use range:
1, aquaculture recycling water treatment;
2, cooling circulating water, industrial circulating water treatment;
3, rivers, lakes, family water features such as eutrophic water treatment;
4, the water reuse mechanism:
