After non-woven or PP fiber filter, the filter is clogged holes are generally difficult to rinse with water, replace the filter regularly. pure water systems Types of water equipment, function and maintenance of water flow gradually decline. Without timely treatment, along with an increase in the resistance of solid impurities trapped sharp rise in the strainer. pure water systems Subsequent disposal can not meet the requirements of the process water flow. Sand filters, pressure rises to a certain level should be promptly after the backwash. When there are local backwash sand filters are flushed out, so sand filter should be periodically supplemented with sand, sand after repeated backwashing, increasing fragmentation levels, while backwash not one hundred percent every punch clean and sand the remaining pure water systems sludge is gradually increasing, pure water systems the sand will be "harden" is like, you should replace the sand. After non-woven or PP fiber filter, the filter is clogged pure water systems holes are generally difficult to rinse with water, replace the filter regularly.
Therefore, a good reverse osmosis maintenance work is key to ensuring the quality of water. In the course of the reverse osmosis membrane the membrane surface is higher than the salt concentration in the body fluid concentration after filtration became water. This phenomena is called concentration polarization. Concentration polarization effects is to make some salt deposited on the outer membrane, blocking production of reverse osmosis membrane water channel, so that the membrane water production decreased. Will be deposited on the surface of the membrane, in particular the appearance of some organic pure water systems material charged to the reverse osmosis membrane of the water is not continuously flushed or rinsed off periodically, it will attract the charged pure water systems organic material and its viscosity at the membrane surface. In the accumulation of organic matter pure water systems on the membrane surface of the membrane damage caused by salt precipitation than the surface of the membrane worse, sometimes the damage is irreversible film appearance and various salts of organic matter concentrations are much higher than the main flow, which is the reproduction of bacteria provides a wealth of nutrition. pure water systems A large number of microbial groups produced not only clog the water channel, and because of the reverse osmosis membrane itself is organic matter will be decomposed by microorganisms, causing irreversible damage. Water, such as chlorine and other oxidizing substances enriched in membrane form, enriched to a certain pure water systems level beyond the film itself pure water systems can bear concentration, reverse osmosis membranes will quilt oxidative decomposition.
