softener resin
Thread Content
Today I received a reverse osmosis system design task. The customer requested a softener for pretreatment, and the softener should be disinfected with hot water. Is there any softening resin that can withstand 85 degrees? Or is the customer's request unreasonable? ?
There are 85 degree resistant resins, 001x7 sodium type is fine.
It should be ok, normal 001* The resin Na type of 7 can withstand 120 degrees, and the H type can withstand 100 degrees.
Resin's ability to withstand high temperatures is not a big problem, but why use a resin softener for pretreatment? We all first use sand filtration, carbon filtration, reverse osmosis, and then pass through the resin, so the pollution to the resin should be relatively small.
Oh, thank you everyone for downloading the information of 001×7 resin today. The sodium type is resistant to 120 degrees.
The use of resin after reverse osmosis mentioned on the 4th floor should be the traditional mixed bed after reverse osmosis. Most of the ones I come into contact with now are pre-treatment to soften first, and then reverse osmosis. If the water quality requirements are high, add EDI.
At present, it is true that this application method of oil has not been exposed to water treatment for a long time!
