The filtering steps of pure water equipment are as follows:
Water purification: the use of water purification technology to remove a large amount of organic components, heavy metal ions, harmful impurities and bacteria, and retain the beneficial trace elements of the human body, clear, sweet, rich oxygen can be directly consumed, known as water purification.
Purified water: the use of reverse osmosis technology to remove the organic components in water, inorganic components, heavy metal ions, harmful impurities and bacteria and minerals, can be directly consumed, known as pure water.
Activated carbon is a porous carbon compound is developed, the gap structure extremely rich (per 1000 square meters, thus Donetsk) has strong adsorption capability, is one of the most commonly used water treatment water purification materials. To remove the odor, color, organic matter, residual chlorine, improve the taste of water.
The filtering precision is generally 0.03-15 microns, is a kind of static pressure driven separation process by using membrane sieving effect sieve filtration medium medium mesh, microfiltration membrane has a porous structure is neat and uniform, the static pressure difference under film hole smaller than the particle through the membrane, membrane pore than large particles be trapped on the membrane surface, the different sizes of the group allocated to separate.
All kinds of common PP filter, ceramic filter are microfiltration category, sediment, rust and other large particle impurities in the water can be filtered.
The filtration precision between microfiltration and nanofiltration, the pore size of 0.002 microns -0.1 microns, is a kind of using pressure membrane separation technology, is under pressure from high pressure to low pressure water filtration end end, ultrafiltration can generally be removing rust, Qin sand, colloid, bacteria, and other harmful organic molecules. The material, and can retain some mineral elements beneficial to human body. Is a core component of mineral water, spring water in the production process.
Nanofiltration membrane between reverse osmosis and ultrafiltration membrane, which is characterized with high removal rate of only melt specific, mainly removed as a solute particle diameter nm, the MWCO 100-1000MWCO is mainly used for removal of hardness components, three halogenated methane in body, odor, color, pesticide, synthetic detergent, the soluble organic matter and evaporation residues in drinking water. At very low pressure still has high softening, desalination performance. Desalination of high hardness water is the largest field of application of nanofiltration membrane.
Reverse osmosis technology is a kind of ultra high precision by using the United States at the beginning of 60s to develop a space pressure membrane separation technique. Its principle is in the raw water side on natural osmotic pressure higher than the pressure, reversing the natural penetration direction, the pressure to the other side of the pure water in the RO film, which is the reverse osmosis the process and nature.
Reverse osmosis filtration precision in 0.00001 micron, theoretically which can filter impurities (including water almost all harmful and beneficial), only allows water molecules to pass through. Generally used in drinking water, industrial manufacturing pharmaceutical ultra pure water, ultra pure water. Reverse osmosis technology needs to back pressure. Water backwash the use of reverse osmosis membrane control system, improve the service life of the membranes.
KDF is the abbreviation of KDF, is a kind of high purity copper and zinc alloy by electrochemical oxidation reduction of water treatment, it can remove up to 99% of the chlorine and water containing lead, mercury, nickel, chromium and other metals. The melting control of bacteria, fungi, algae, water and dirt the breeding of outstanding achievements. To a certain extent, improve the pH of the water, reduce the mineral crystals to prevent fouling.
Scope of application of pure water equipment:
Space water, purified water, distilled water, etc;
Water for production and reduction of alcohol;
Prior preparation of water for pharmaceutical, electronic and other industries;
Concentration, separation and purification of chemical process and preparation of water distribution;
The boiler water supply in salt water.
Seawater and brackish water desalination; water and wastewater treatment of paper making, electroplating, printing and dyeing industry, etc..
