Pure water machine
close Water Purifier refers to the water purification equipment that removes or reduces the salt in water (mainly the strong electrolyte dissolved in water) to a certain extent. 1.0 - 10.0 μ S/cm, resistivity (25 ℃) 0.1-1.0 * 106cm, salt content of 1-5mg/L Function: it is used to filter the floating objects, heavy metals, bacteria, viruses, etc. in the water. It has a high filtration technology, generally five levels of filtration, the first level is the pp cotton filter element, the second and third levels are activated carbon, the fourth level is RO reverse osmosis membrane, and the fifth level is precision activated carbon, It is mainly used to improve the taste, so the water purifier is more suitable for the product classification in areas with serious tap water pollution: 1. From the perspective of use, it can be divided into: 1. domestic drinking water purifier (household water purifier); 2. Laboratory pure water machine (also called ultrapure water machine); 3. Industrial water purifier 4. Large industrial water purifier. 2、 According to the usage, it can be divided into: 1. Manual type, also called economic type. The economical water purifier uses manual backwash valve. 2. Automatic type, the automatic type is a full computer automatic washing pure water machine, which can be washed through the computer control panel. 3. Self cleaning type, also known as self cleaning type, is self cleaning. It is the reverse osmosis series of self cleaning water purifiers. Its advantage is that it does not require economic manual operation or automatic electrical components. It is not only simple in structure, but also can achieve self-cleaning of the whole machine. 3、 According to the combination of main engine and water storage barrel, it can also be divided into split type and integrated type. The split type covers a large area, and the water storage barrel is separated from the body; The main engine of the integrated water purifier is together with the water storage bucket, which occupies a small area and has a beautiful appearance. Ion exchange of ion exchange ultrapure water machine is a special solid adsorption process, which is carried out in the electrolyte solution of ion exchanger. The general ion exchanger is a kind of solid granular material that is insoluble in water, namely ion exchange resin. It can absorb a certain cation or anion from the electrolyte solution, and replace another ion with the same charge sign contained in itself in equal amount, and release it into the solution, which is called ion exchange. According to the types of ions exchanged, ion exchangers can be divided into cation exchangers and anion exchangers. Components Industrial water purifier consists of pretreatment system, fine treatment system and post-treatment system. After raw water passes through PP filter element (sand bar filter), activated carbon unit, water softener unit and other pre-treatment systems, the content of suspended solids (particulate matter), colloid, organic matter, hardness, microorganism and other impurities in the water is greatly reduced, so as to reduce the processing load of subsequent reverse osmosis, electric desalting and other polishing systems and extend their service life.
