NX Filtration receives order from GreenTech for full-scale advanced water treatment applications in China
NX Filtration, the global provider of breakthrough direct nanofiltration (dNF) membrane technology for pure and affordable water, was selected by GreenTech Environmental, a leading publicly listed company in advanced water treatment and wastewater recycling in China, to supply its dNF membranes for large-scale water supply projects in China.

The commercial agreement follows a pilot program of approximately one year, in which NX Filtration’s dNF technology was tested on the removal of emerging micropollutants from surface waters in China. The new full-scale project developments will use dNF membranes to produce drinking water from micro-polluted surface water and quality reclaimed water from alternative water sources, which are increasingly important sources for water production across China.

In anticipation of additional large-scale drinking water projects in China, GreenTech and NX Filtration also concluded a partnership agreement that forms the basis for further expansion across China. In this context, Greentech has started the development of standard pre-engineered modular systems, each with a capacity of 10,000 m3 per day, based on NX Filtration’s dNF technology. These standard building blocks will enable fast delivery of future large-scale projects.

David Wang, Senior Vice President at GreenTech, explains: “We are very happy to engage NX Filtration on this first large-scale project based on their direct nanofiltration technology. Based on our extensive pilot tests we see the great potential of this technology, that effectively removes micropollutants from surface water, whilst at the same time provides strong environmental benefits. We are looking forward to continue to work with NX Filtration to engage in various drinking water projects across China.”
