Products & Technologies

a type of ultra-low pressure with the molecular cutoff of 100~500 Dalton, and the soluble inorganic salt passes selectively.

Product features

Stable performance: Edge cutting equipment and process which makes the performance of the elements uniform and stable.

Low operational pressure: DF membrane runs under low operational pressure compared to traditional nanofiltration and reverse osmosis, which makes DF membrane lower operational cost.

High product water: higher product water under same operational pressure compared to traditional nanofiltration and reverse osmosis.

Excellent molecular cutting off: the molecular cutoff is 100~500 Dalton, which keeps the organic pollution and heavy metal out. 

Outstanding contaminant resistance: the membrane surface is smooth and slippery with good hydrophilicity which is close to electric neutrality.

Appropriate rejection: retains the mineral matters that human body needs.

High COD removal: water can achieve higher than Level III of Surface Water Quality Standard with lots of COD serious reduction after treatment of National I-A Class feed water.
