Pure water equipment, incorrect operation problems - 【 3 m filter.

Pure water equipment usually USES the reverse osmosis technology, reverse osmosis is a kind of with the aid of choice through ( Half through) Sex film skill to pressure as the driving force of membrane separation technology, when system and the pressure is greater than in the aqueous solution of osmotic pressure, the water molecules through the membrane unceasingly, after producing water flows into the central tube, and then out in the end the impurities in the water, such as ion, organic matters, such as bacteria, viruses, interception on the inlet side of the membrane, and then in the thick water outflow water end, so as to achieve separation and purification.
pure water equipment or improper operation will cause membrane water treatment filter performance of damaged
1, osmosis device of residual gas under high pressure operation, form can be damaged by pneumatic hammer film
always have two things happened: after emptying,
A, equipment to run, gas out of everything and booster to run fast. Should be under the pressure of 2 ~ 4 bar will do the rest of the air, gradually step up running again.
B, the joint between pretreatment equipment with high pressure pump seal is bad or leaking, Especially after micro filter and its pipeline leaking) When pretreatment water supply is not very enough, such as micro filter clogging, in the place with bad sealing part due to the vacuum will be sucked into the air. Should be clean or replace the filter, ensure the line does not leak.
all in all, the absence of air bubbles in the flow meter should be gradually step up running, found in the operation of the air bubbles should be gradually step-down check reason.
2, osmosis equipment shutdown method incorrect
A shutdown, when quick buck did not thoroughly rinse. Due to the membrane thick water side of inorganic salt concentration higher than that of raw water, easy fouling and membrane pollution.
B, with adding the chemical pretreatment water rinse. Because it contains chemical reagent water may cause membrane fouling during the equipment stoppage.
when preparing to turn it off, reverse osmosis equipment should stop adding the chemical reagent, gradual step-down to about 3 bar with pretreatment of good water rinse 10 min, until the condensed water TDS TDS with raw water is very close.
