The microporous filtration of a Drum Filter Screen is a mechanical filtration method. The Drum Filter Screen is suitable for separating the tiny suspended substances in the liquid, mainly Phytoplankton, Zooplankton and organic residue to a large extent, so as to achieve the purpose of liquid purification or recovery of useful suspended substances. The fundamental difference between microfiltration and other filtration methods is that the filtering medium used - a stainless steel wire mesh or microfiltration mesh - has a particularly small and thin total pore size. This type of filter has a relatively high flow rate characteristic under low hydraulic resistance, making the size of suspended solids intercepted always smaller than the micropores on these filters. Microfilters are water treatment equipment made using this principle. Microfilter is a new economic water treatment equipment, which can be used for raw water filtration (such as algae removal) in waterworks, industrial water filtration in power plants, chemical plants, textile printing and dyeing plants, Paper mill and other industrial water filtration, circulating cooling water filtration, wastewater purification and sewage treatment. A typical example of using microfiltration machines to recover useful suspended solids from liquids is the pulp (fiber) recovery of papermaking white liquor, with a recovery rate of up to 98%. After the white liquor is recycled and purified, it can be reused and also meets national emission standards.
The Drum Filter Screen is suitable for maximizing the separation of small suspended substances (such as pulp fibers) present in liquids, achieving the goal of solid-liquid two-phase separation. The difference between microfiltration and other methods is that the clearance of filter medium is very small. With the centrifugal force of screen rotation, the microfiltration machine has a high flow rate under low water resistance, and can intercept and retain Suspended solids. Its efficiency is 10-12 times that of inclined screen. The fiber recovery rate can reach more than 90%, and the recovered fiber concentration can reach more than 3-5%. Microfiltration machines are specially developed to address the issues of easy blockage, damage, heavy maintenance workload, and high secondary investment in existing microfiltration machines. They are one of the practical technologies suitable for papermaking wastewater treatment. Micro filter is a new type of micro filter developed based on foreign technology and tailored to China's national conditions. Microfilters are widely used in various occasions that require solid-liquid separation, such as urban domestic sewage, aquaculture, papermaking, textile, printing and dyeing, chemical wastewater, etc., especially for the treatment of papermaking white water, which can achieve the goal of closed circulation and reuse.
