The suspension was filtered residue layer has filtration, depth filtration and sieving three ways. ① residue level filtering: initial filtration filter media only large solid particles entrapped small particles with filtrate passes through the filter media. After an initial residue layer, layer of filter residues play a major role, then large and small particles are trapped, such as plate and frame filter press filter. ② depth filter: The filter medium thick, containing solid particles in suspension no less HEPA filter manufacturer, and the particles are smaller than the filter media channels. Filtration, after being adsorbed on the particles into the pores, such as porous plastic tube filter, sand filter filtration. ③ sieve: filtration of solid particles trapped in the pores are larger than the filter media, filter media does not adsorb inside solid particles, such as a drum filter screen filtered sewage coarse impurities. In the actual filtering process, three ways often occur simultaneously or sequentially. Performance air filter contaminated air is clean to the state of production and living needs, which is the air up to a certain cleanliness. How air filter air: general air filter air purification equipment roughly divided into the following methods and procedures. 1, multiple filters --- prevent airborne dust and bacteria into the interior of multiple carbon filter dust and germs effectively intercept, filter air HEPA filter production equipment to ensure clean air into the room. 2, titanium antivirus --- degradation of indoor air formaldehyde, benzene and other organic toxic pollution nanoscale titanium dioxide is activated by ultraviolet light, air filter effective degradation of radioactive contamination in the air formaldehyde, benzene and other organic poison gas. 3, anion oxygen --- increase the indoor air and the right amount of oxygen to keep the content of stable oxygen anion generator to the indoor air, make sure to enter the home of a sufficient amount of oxygen in the air to keep vibrant automatic sewage filter accuracy, strengthen Water Filters Air Filter> 4, PTC ceramic heating --- heated indoor air to a comfortable temperature PTC ceramic heating plate into the interior of the new winter wind assisted preheating, appropriately increase the indoor temperature filter to filter the air and let the warmth of home comfortable. 5, UV sterilization --- potent kill airborne bacteria pandemic virus has a strong effect of ultraviolet light to kill viruses and bacteria in the air of the epidemic, people far away from the source of infection, filtered air, family health care.
