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 filtration: filtration media thicker, the suspension containing small solid particles, and the particles are smaller than the filter media pores. Filtration, after being adsorbed on the particles into the pore water filter, such as a porous plastic tube filter, sand filter filtration. ③ sieve: filtering solid particles entrapped pores are larger than the filter medium, the filter medium does not adsorb the internal solid particle filter, such as a drum filter screen filtered sewage coarse impurities. In the actual filtration process pipe filters, three ways are often simultaneously or one after another. Shanxi Run-Environmental Engineering Limited was founded in 2005, is a professional sewage treatment, waste gas treatment, dust handling and other environmental projects and research and design of high-tech enterprises. The following is a filter Features 1. Fully automatic operation, continuous water: between the units in the filter combination, alternating between the backwash process, work, automatic switching between backwashing state, to ensure continuous water; anti- rarely wash water consumption, accounting for only 0.5% of the water; such as with air-assisted backwash, since more water consumption can be reduced to 0.2%. Speed ??and thorough backwashing, just tens of seconds to complete 2. Long life: new plastic filter elements sturdy, no wear, corrosion, fouling rarely, after years of industrial and practical verification, use 6 to 10 years and no wear and tear, not aging, filtration and backwash effects are not due to the use of time and worse. 3. high quality, low maintenance: products meet appropriate quality standards, all products in the factory have been testing and commissioning of simulation conditions, without special tools, parts rarely; easy to use, just a regular inspection, hardly require routine maintenance.
