   Many well known, household water purifiers, also known as "reverse osmosis water purifier," and RO reverse osmosis membrane is the essence of household water, and along with the peoples living standards improve penetration also increasingly higher. But many consumers RO reverse osmosis membrane has a deep understanding for the RO reverse osmosis membrane fouling do not know how to deal with, then the following small series just like a look at it.

鍑€姘村櫒 How to prevent clogging of the RO membrane

   1. Learn local water wherein

   To understand the raw water quality to the user, TDS indicators do not represent calcium and magnesium ions the content of water is sometimes not high TDS measurement, but the hardness index is already beyond the normal parameters several times or more, if this is the case, it is preferable to increase the pre-stage in pure water softener, water softening after the first re-entering the water purifier, it can greatly increase the life of the RO membrane.

   2. Regular cleaning of the RO membrane

   After prolonged use, the surface of RO membrane fouling and deposition likely to occur, clogging of the membrane pores, decreased production of water, so the film is periodically pollution cleaning is necessary, but can not wait until after the reverse osmosis membrane system to clean the pollution is very serious, this will increase the difficulty of cleaning, but also an increase in the cleaning step and cleaning time extension, to correctly grasp the opportunity to clean, timely removal of dirt. .

   3 See RO membrane properties

   Usually the proportion of pure water and waste water are controlled in 3: 7 or 1: 3, but some manufacturers and purifier franchisees excess flow valve used reached this standard, so that less waste water discharge, which in turn has increased the workload of the RO membrane, under overload, it is easy to plug the RO membrane, which is the most common problem.

   RO membrane plugThe plug solution

鍑€姘村櫒 1 first determines whether the RO membrane is really clogged;.

   2 for water quality in the region, whether the main component of the scale is mainly composed of calcium, magnesium salts thereof;.

   3 detergents (detergents market scale cleaning) arranged syrup (10% HCl) composition according to the scale, or diluted, or special purpose cleaners RO membrane bubble 24 hours ;

   Next, an RO membrane 4 after the bubble rinsed with RO water produced ultrafiltration membrane pressure washing, to close the outlet when the rinsing water, waste water outlet opening only;.

   5. ultrafiltered water produced simultaneously with high pressure water from the RO membrane flushing water inlet and water outlet, the water inlet pressure RO membrane is less than the pressure from the water inlet port, but pressure the difference is not too large to prevent the filters break and allow water to wash away the fouling material film adhering to the surface, which can effectively solve the clogging.
