Guangdong industrial pure water machine manufacturer Guangzhou filter water purification equipment limited company dedicated to water treatment industry, the company has a professional R & D personnel, long-term production of a variety of different specifications of large industrial water treatment equipment.

Industrial pure water machine water front filter pretreatment system can make the suspended material in the water ( particulate matter ), colloid, organic matter, hardness, microorganisms and other impurities are greatly reduced, in order to reduce subsequent reverse osmosis, electric salt and other refined processing system processing load, prolonging its service life. It consists of pretreatment system, precision processing system, processing system three system and purification column unit, water softener, reverse osmosis unit unit unit unit, activated carbon, ultrafiltration, UV unit,

Purification column unit six filtering elements.

Water softener unit

Large and medium-sized water systems often use fully automatic water softener to remove calcium and magnesium ions in raw water. Fully automatic water softener by sodium ion resin tank, regenerating salt box and multi-way control valve component, can set the program control, automatic regeneration ( time / flow type two control modes ), regeneration using siphon principle of suction salt, salt and water regeneration time, usually for 2 hours. A small desktop machine generally use 10 inch / 20 inch water softener resin filter to reduce the water hardness.

Purification column unit

Purification column filled with the United States Haas / Dow company produced UP nuclear grade resin, when the raw water through a purification column, water cations and cation resin in H + exchange, anionic and anion exchange resin OH - ion exchange, exchange after entering the water of H + and OH - will immediately be combined to generate a H2O, thereby the raw water in ion can be removed, the water resistivity of up to 18.3 M & . Cm.

The reverse osmosis unit

RO ( Reverse Osmosis ) reverse osmosis technology is the use of pressure difference for the dynamic membrane filtration technology, derived from the United States of America nineteen sixties Aerospace Science and technology research, after gradually into civilian, it is widely used in scientific research, pharmaceutical, food, beverage, desalination and other fields. The RO reverse osmosis membrane pore size as small as nanoscale ( 1 nm = 10-9 meters ), under a certain pressure, H2O molecules may pass through a RO film, while the source water inorganic salt and heavy metal ions, organic matter, colloid, bacteria, virus and other impurities can not pass the RO membrane, so that through water and not by the the condensed water to distinguish strictly. RO membrane to ions, colloid, bacteriological and molecular weight of greater than 300 Dalton organic material ( including heat ) high removal rate reaches above 99%, to a low ion ( NA +, K + ) removal rate reaches 95%, when the source conductivity < 3505&micro; s / cm, RO pure water conductivity is usually less than or equal to 55&micro; s / cm, in line with national level three water standard. After the atomic ion exchange column filtration cycle, water rate up to 18.2M & . Cm. Reverse osmosis is up to 90% ~ 99% impurity removal rate the most economic method, but also the reagent grade water system the best pretreatment method.

Activated carbon unit

Activated carbon with large specific surface and pore size, with minimal ( 10 ~ 30 angstroms ) microporous, organic colloid, residual chlorine, iron ion with an apparent adsorption filtering effect. Type pure water machine, water purifiers and other commonly used 10 inch / 20 inch activated carbon filter. Large water unit common glass steel / stainless steel active carbon filtration tank.

Ultrafiltration unit

Ultra filtration membrane is also known as the hollow fiber ultrafiltration membrane. The aperture between reverse osmosis and microfiltration, about 0.01 ~ 0.1 M, commonly used as a water system after treatment device, can be used to intercept solutions of various particles, large molecules, bacterial, virus, pyrogen. Ultrafiltration membrane aperture is formed by certain molecular weight substances being tested, and the molecular weight of the numerical representation, can remove pyrogen in the ultrafiltration of molecular weight is usually 6000 Dalton ( Dalton ).

Ultraviolet detector unit

Ultraviolet light is an invisible light, were present in the spectra of ultraviolet end outside, it is called ultraviolet, according to different wavelength range, is cut into A, B, C three band, wherein the band in C ultraviolet wavelengths between 240 and 260nm, as the most effective sterilization band, band the wavelength is strongest 253.7nm. When the ultraviolet device generates an adequate dose of strong UV exposure to water, liquid or air, in which a variety of bacteria, viruses, parasites, microorganisms or other pathogens in the ultraviolet UV-C radiation, the cells in the tissue of DNA, RNA is damaged, thereby preventing sub cell regeneration, ultraviolet disinfection equipment without using any chemical pharmaceutical circumstances, a relatively short period of time ( usually 0.2-5 seconds ) to kill the water, liquid or air in more than 99.9% of the bacteria and virus. Scientific experiment to prove that, at wavelengths of 240-280nm ultraviolet light with high bactericidal function. Modern ultraviolet disinfection technology is based on the modern epidemic prevention science, optics, biology and physics and chemistry based on the use of special design, high efficiency, high strength and long life C band ultraviolet generating device, to produce the strong ultraviolet C irradiation water ( air or solid surface ), when the water ( air or solid surface ) in a variety of bacteria, viruses, parasites and other pathogens, algae by a certain dose of ultraviolet C radiation, the cells in the DNA structure was destroyed, thus does not use any chemical drug cases killing aquatic bacteria, virus, and other viruses, to achieve the purpose of disinfection and purification.
