Performance characteristics

DowFLMTECTMNF270-400Nanofiltration membrane elements have a large area and high water production, and are specifically designed to highly remove total organic carbon.TOCAnd trihaloalkanesTHMThe product developed based on the precursor allows a moderate passage of hardness components and a moderate or high degree of passage of other salts.

DowFLMTECTMNF270-400It is an ideal membrane element for removing organic matter from surface water and groundwater and partially softening it to achieve specific water hardness requirements, maintain taste, and keep the water supply network stable. The net driving pressure required for the membrane area of this component is low, enabling it to remove organic compounds from water during low-pressure operation.

Product specification

1,The water production capacity and desalination rate are based on the following test conditions:500ppmCaCl2,0.48MPa,25℃,15%Recovery rate.2000ppmMgSO4,0.48MPa,25℃,15%Recovery rate.

2,The flow rate of specific components may vary, but it will not be lower than the given value15%.

NF270-400The component can be placed with an inner diameter of203Inside a pressure vessel in millimeters.

Work limit

aWhenpHThe value exceeds10At that time, the highest temperature for continuous operation is35℃

bIn some cases, the presence of free chlorine and other oxidants can lead to the failure of water production membrane elements. It is recommended to remove the residual free chlorine through pre-treatment before the membrane elements come into contact with these oxidants.
