What is the ultra-high efficiency filter process

In many places are used to filter the role of the filter is very big, is an essential part of many places, efficient filter filter is a kind of technology is more sophisticated, many people do not understand the high efficiency filter, small make up today about the simple introduction for everyone - the process flow and characteristics of super high efficiency filter under.

Each HEPA filter has been tested by the nano flame method, with high filtration efficiency, low resistance, large dust capacity and other characteristics of HEPA filter can be widely used in optical electronics, LCD liquid crystal manufacturing, biomedicine, precision instruments, beverages, food,PCB printing and other industries of dust-free purification workshop air conditioning end supply. High efficiency and ultra efficiency filters are used at the end of the clean room. They can be divided into: high efficiency filter with separator, high efficiency filter without separator, high air volume filter, ultra efficiency filter and so on. There are also three kinds of high efficiency filters, one is ultra-high efficiency filter, can do purification of 09.995%. One is an antibacterial type HEPA filter without separator, which has an antibacterial effect and prevents bacteria from entering the clean workshop. The other is a sub-HEPA filter, which is cheap and used for purification space with low requirements before.

Hepa filter by adding flocculating agent in the pump to the circulating water, raw water through the booster pump, flocculating agent after the pump impeller stirring mixing tiny solid particles suspended and colloidal substance in the raw water of micro flocculation reaction, quickly generate greater than 5 micron floc size, flows through the filter system piping into efficient asymmetric fiber filter; The flocculant is intercepted by the filter material. The system uses air-water combined washing backwash air provided by the fan, backwash water directly provided by tap water. Wastewater from the system (high efficiency automatic gradient density fiber filter backwash wastewater) is discharged into the sewage treatment system.

Mechanical filtration sewage treatment the most commonly used method, according to different mechanical filter medium filtering equipment is divided into Sang granule medium filter and fibre filter two kinds of granules medium mainly sand as filter medium, the particle filter, such as through clever grain of filter material in between adsorption and sand pore water interception function of filtering of solid advantage is easy to recoil defect is filter speed is generally not more than slow 7m/h the core filter layer is only the surface of the filter layer; The low filtration accuracy is only 20-40um, which is not suitable for rapid filtration of sewage containing high turbidity. Efficient asymmetric fiber filter system USES asymmetric fiber bundle as the filter material, the filter material for asymmetric fiber, on the basis of fiber bundle filter material, added a nuclear makes it both fiber filter material and particle filter material due to the advantages of the filter material of special structure, the pore porosity of filter bed soon formed under the big small gradient density, filter speed fast, sewage star is big, easy to reverse wash through special The design, so that the dosing, mixing, flocculation, filtration and other processes in a reactor so that the equipment can effectively remove the suspended organic matter in aquaculture water, reduce water COD, ammonia nitrogen, nitrite, etc., especially suitable for temporary pond circulating water solid suspended solids filtration.
