What is the reason for the formation of a sticky diaphragm on the surface of the pre-reverse osmosis security filter cartridge? The result is that the filter element is replaced once every 2~3 days.
It should be the inlet water quality does not meet the standard, we recommend that you do a water quality test.
What factors affect the turbidity of the water from the security filter?
1. The quality of incoming water, because the precision filter is used as a filtration medium, the higher the turbidity of the incoming water, the heavier the load of the filter element, the greater the possibility of clogging and contamination. That is to say, if the turbidity of the incoming water does not meet the standard, the turbidity of the produced water is difficult to meet the standard.
2. Filter cleaning frequency, to achieve 1um filtration accuracy, generally only PP cotton filter can be done, but PP cotton filter in the use of a period of time, there will be a layer of filter residue on the surface of the filter element, these residues will contaminate the filter element, clogging the aperture. Therefore, the need for regular cleaning of the cartridge. At the same time, the service life of PP cotton cartridge is relatively short, generally a few months to be replaced, even if there is no damage, to the service life must be replaced.
3. Filtration process, in order to achieve a low turbidity water, we must ensure that the filtration process is designed reasonably.
How to improve the turbidity of the water from the security filter
1. Improve the quality of incoming water
2.Do a good job of 1um precision filter routine maintenance work
3. Regular cleaning and replacement of filter elements
Security filter filtration characteristics
1. The security filter features highly efficient removal of water, oil and solid particles, and can completely remove impurities above 0.0.1μm. The concentration of particles and oil can be controlled at 0.01ppm/wt. For liquid-solid filtration, the smallest particle that can be filtered is about 0.45um, and for gas-solid filtration, the smallest particle that can be filtered is about 0.3um, and the filtration rate can be 99.9%, and the filtration pressure difference is low.
2. The overall structure of the security filter is reasonable, small in size and light in weight.
3. high regeneration efficiency. The simple gas-liquid rapid recoil and blowback method can regenerate the blocked microporous tube efficiently and quickly, and when the filter tube is used for a certain period of time, it can be regenerated by chemical methods, so that the service life of the filter tube is longer.
4. The security filter has superior chemical corrosion resistance, and the microporous tube is resistant to various acids, alkalis, salts and most organic solvents, and is non-toxic, odorless, and free from dissolution of foreign substances, which is extremely suitable for pharmaceutical, food, chemical, environmental protection and other industrial applications.
5. The security filter has three-stage segmented purification treatment, replaceable filter element and long service life.
6. The security filter has high dirt-holding capacity, good temperature resistance, large flow rate, convenient operation and no fiber shedding.
