Purified water conductivity high root cause analysis and solution

1, in general, high electrical conductivity is refers to the whole water treatment system in line with the initial state, no change. This time cause of high conductivity is the reverse osmosis membrane component aging led to the decrease of the desalination rate, correct treatment method is to change the reverse osmosis host of reverse osmosis membrane, usually change frequency ( Cycle) Is 2 - 3 years. 2, other conditions: a sudden rise, making machine run normally, conductivity, displacement increases. This kind of situation is due to the reverse osmosis membrane module connection seal leak caused a dramatic increase in conductivity, recommend replacing seal ring. Water quality of the concrete method is to test each film components, find out the leak part replacement. B, making machine in a second conductivity increases boot when it is difficult to come down or fall time is too long, this kind of situation general common in two-stage reverse osmosis, in the middle of the primary and secondary general by sodium hydroxide to adjust the amount of carbon dioxide removal from water, and the quantity of sodium hydroxide adding conductivity, suggest adding quantity adjustment. C, making machine in the running for a period of time after water rate did not change, the conductivity increases, displacement increases. That film by oxidizing dielectric degradation, the conductivity increases, the membrane module needs to be replaced. D, sand making machine pretreatment of carbon purification filtering effect to reduce or failure, not regular, timely backwash ( Water conductivity will be relatively higher) 。 E, RO water security filter dirty plugging pressure difference did not change in time 3, in addition, the reverse osmosis making machine is a big system and other factors, it is recommended that you appear problem, leave daily operation records and contact analysis problems. Familiar with making machine manufacturers for making machine system, can quickly find out the problem. Detergent packing machine, laundry detergent packing machine, reverse osmosis water treatment making machine washing powder production factory house, the last, the basic requirement of reverse osmosis water treatment device
