GreenTech starts pilots with NX Filtration for drinking water production in China

Enschede, the Netherlands, 20 January 2022

GreenTech Environmental, a leading company in advanced water treatment and wastewater recycling, headquartered in Beijing, starts a pilot program with NX Filtration’s direct nanofiltration (dNF) membranes for the production of drinking water in the Chinese provinces of JiangSu and Zhejiang.

GreenTech Environmental Co. Ltd from Beijing focuses on engineering, construction, operation management and financing for advanced water treatment and waste-to-resources using membrane technologies. Surface water from rivers and lakes is a vital source for water production in China. Similar to European surface waters, the removal of a variety of emerging micropollutants is an increasing challenge. To address this challenge, GreenTech will start a pilot program on surface water treatment with NX Filtration’s dNF technology.

In January 2022, the first pilot project, based on NX Filtration’s fully automated Mexpert pilot system, will start at a drinking water production location in the JiangSu Province. In the course of 2022, a second pilot will be initiated for drinking water production in the Zhejiang province.

Mr. David Wang, Senior Vice President at GreenTech, explains: “We are very happy to start working with NX Filtration’s direct nanofiltration technology. With the pilot projects we are looking to research the removal efficiency for a variety of organics  and emerging micropollutants, such as pharmaceuticals, personal care products and endocrine-disrupting compounds.”

Robert Gerard, sales director at NX adds: “We are proud to deploy our unique direct nanofiltration membranes for GreenTech to produce drinking water from surface water in China. As we control membrane properties on a nanometer level, we have developed a highly effective way of removing contaminations, while containing minerals that are desirable in drinking water. Contrary to other filtration technologies, our direct nanofiltration membranes are capable of treating polluted waters in a simple one-step process, with lower energy usage and avoiding the use of chemicals in pretreatment.”
