The filter is the key to the ultrapure water machine

Nov 20, 2019

 In ultrapure water machines, the filter cartridge is a very critical component, and it is an indispensable material for purifying water.  With the rapid development of the laboratory, medicine, and chemical industries driving the growth of the ultrapure water machine market, competition between enterprises is becoming fiercer. Nowadays, when choosing ultrapure water machines, users pay more and more attention to the filtration accuracy and life of the filter element.  etc.

 It is understood that the filter cartridges of current ultra-pure water machines mainly include reverse osmosis membranes, precision filters, activated carbon filters and other types.  Among them, reverse osmosis membranes are used more in small ultrapure water machines, with a typical life of about 2-3 years; precision filters, also known as filter filters, wire-wound filters and PP meltblown filters, mainly filter large particles in raw water.  Its life is generally 36 months; the activated carbon filter is divided into compressed activated carbon filter and bulk activated carbon filter, which integrates adsorption, filtration, interception and catalysis, and can effectively remove organic matter, residual chlorine and other radioactive substances in water, and has decolorization.  The effect of removing odor.

 At present, PP filter cartridges and activated carbon filter cartridges are widely used in the industry.  In addition, for the current filter market, in order to enhance market competitiveness, some ultrapure water filter research and development manufacturers increase research on filter technology according to user needs, and improve from the aspects of structure, material selection, filtration accuracy, and life.

 For example, some companies have developed a new type of composite filter. The filter is equipped with high-purity copper-zinc alloy filter material / activated carbon fiber / ULU slow-release scale-inhibiting crystals, which can continuously remove residual chlorine and iron-manganese heavy metals in source water.  Ions, and have the effect of inhibiting bacteria and other microorganisms.  Compared with conventional filters, this composite filter greatly improves the efficiency of water treatment, and extends the replacement period of the filter to 6-12 months, which saves costs and improves production efficiency for the enterprise.

 At present, domestic technical research and product innovation research and development of ultra pure water filter cartridges have become more and more effective.  However, some ultra-pure water machine manufacturers remind that the filter has a certain life, so when using the ultra-pure water machine, the user needs to replace the filter of the device regularly to ensure the normal operation of the device.  The reason for regularly replacing the filter is mainly due to two considerations.

 First, if the filter of the ultrapure water machine is not replaced for a long time, the trapped pollutants will continue to accumulate on the surface layer. Over time, more and more pollutants will occur, and a series of chemical reactions with the water body will cause internal bacteria.  Breed.

 Secondly, the filter has a service life.  If the filter is not replaced in time after the use cycle is reached, the inside of the ultrapure water machine will be easily blocked due to the accumulation of pollutants. At this time, the purification effect of the equipment on the raw water has begun to be greatly reduced.  The blockage will become more and more serious, and may even cause secondary pollution, leading to substandard water quality and reduced water production efficiency.

 Therefore, in order for the ultrapure water machine to exert its due effect and role, and to ensure the quality of water quality, regular replacement of the filter is necessary.

 "Many customers report that it is troublesome to replace the filter, but there will be various conditions if the filter is not changed for a long time. In fact, it is because there are many problems with irregular replacement, so we need to replace the filter."  You can also contact the manufacturer's after-sales personnel to replace it, saving a lot of trouble.

 With the increase of water treatment environment, pure water machine is considered as a market with great potential.  Relevant water treatment equipment enterprises have ushered in a new round of development opportunities, and advanced pure water machine equipment has been continuously introduced, and it is very important for how to apply pure water machines.  In ultra-pure water machine equipment, the filter is a very critical component and an indispensable material for purifying water.
