water treatment plant Reverse osmosis membrane
Vontron is the biggest RO membrane manufacturer in China . Perfect option for house-hold RO units with feed water lower than 2000ppm, like tap water, municipal water, underground water.
EWP is Vontron's global distribution partner and we have been working with Vontron since its establishment.

Normally, we have below three series
Extra Low pressure element-XLP series:
working under extremely low pressure, applicable to feed water with low salinity that requires low rejection rate.
Ultra low pressure element-ULP series:
working under ultra low pressure, applicable to feed water with fairly low salinity.
Brackish water element-LP series:
working under low pressure, applicable to regular or high-concentration brackish water.

ULP21-4040
Ultra-low pressure compound RO membrane element working under the conditions of ultra low operating pressure, ULP membrane series can achieve as high permeated flow and rejection rate as regular low-pressure membranes can. It runs under approximately two thirds pressure of that of regular low pressure compound membranes, and can achieve a rejection rate of as high as 98.0%.
