The ultra-pure water machine adopts pretreatment, reverse osmosis technology, ultra-purification treatment and post-stage treatment to remove the conductive medium in water almost completely, and removes the colloidal substances, gases and organic substances that are not dissociated in the water to a very low level. Water treatment equipment is widely used in medicine and other industries. In ultrapure water equipment, the filter element is a very critical component and it is an indispensable material for purifying water. With the rapid development of the pharmaceutical industry driving the growth of the ultra-pure water machine market, the competition between enterprises and enterprises has become more intense. Nowadays, when users choose ultra-pure water machines, they pay more and more attention to the filtration precision and life span of the filter elements.
It is understood that the current filter elements of ultra-pure water machines mainly include reverse osmosis membranes, precision filter cartridges, and activated carbon cartridges. Among them, reverse osmosis membrane is used in small ultra-pure water machine, the general life is about 2-3 years; precision filter is also called filter element, split-line filter and PP melt-blown filter, mainly filtering large particles in raw water, Its life is generally 36 months; activated carbon filter is divided into compressed activated carbon filter and bulk activated carbon filter, which integrates adsorption, filtration, interception and catalysis. It 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 elements and activated carbon filter elements are widely used in the pharmaceutical industry. In addition, in order to improve the market competitiveness of the current filter market, some ultra-pure water filter cartridge R&D manufacturers have increased the research on filter technology according to the needs of users, and improved from the aspects of structure, material selection, filtration precision and life.
For example, some companies have developed a new type of composite filter element, which is equipped with high-purity copper-zinc alloy filter material/activated carbon fiber/ULU slow-release scale-reducing crystal, which can continuously remove residual chlorine and iron-manganese heavy metals in source water. Ions, and have the effect of inhibiting the proliferation of microorganisms such as bacteria. Compared with the conventional filter element, this composite filter element greatly improves the efficiency of water treatment, and the filter replacement cycle is extended to 6-12 months, which saves the enterprise cost and improves production efficiency.
At present, domestic technical research and product innovation research and development for ultra-pure water machine filter elements have become more and more effective. However, there are ultra-pure water machine manufacturers to remind that the filter has a certain life, so when using the ultra-pure water machine, the user needs to periodically replace the filter element to ensure the normal operation of the equipment. The reason for replacing the filter element regularly is mainly due to two considerations.
First, if the filter element of the ultra-pure water machine is not replaced for a long time, the trapped pollutants will accumulate on the surface layer. As time goes on, more and more pollutants will occur, and a series of chemical reactions occur with the water body, resulting in internal bacteria. Breeding.
Second, the filter element has a service life. If the filter element fails to be replaced in time after the service life is reached, the inside of the ultra-pure water machine is easily blocked due to the accumulation of pollutants. At this time, the purification effect of the raw water on the equipment has begun to be greatly reduced. If the filter element is not replaced in time, it will be over time. Blockage will become more and more serious, and may even cause secondary pollution, resulting in poor water quality and reduced water production efficiency.
Therefore, in order to allow the ultra-pure water machine to perform its due effect and function, and to ensure the quality of the water quality, regular replacement of the filter element is necessary.
“Many customers have reported that it is troublesome to change the filter element, but there will be various conditions in the long-term non-replacement of the filter element. In fact, it is because of the irregular replacement of many problems, so we need to replace it.†The manufacturer’s technician said that the ultra-pure water machine The filter element can be purchased and replaced by itself, or it can be contacted by the factory after-sales personnel to save a lot of trouble.
