NX Filtration supplies its direct nanofiltration membranes to Envirogen for industrial water recycling in the UK
Envirogen, a leading international provider of industrial water treatment solutions and process filtration, selected NX Filtration for the delivery of its direct nanofiltration (dNF) membranes for an industrial water recycling project for a leading manufacturer of advanced materials and components in the North of England. This project follows previous deliveries of microfiltration and ultrafiltration membranes from NX Filtration to Envirogen.

The customer was looking for an optimal and sustainable solution enabling them to recycle more than 75% of their wastewater stream. Envirogen piloted various technologies on-site and selected NX Filtration’s hollow fiber direct nanofiltration (dNF) membranes as the most effective and sustainable solution to remove or reduce key contaminants from the wastewater and enable the reuse at the customer’s facilities.

The current set-up has a capacity of 45 cubic meters per hour and has been designed in a modular way, facilitating efficient future extensions to enlarge the capacity.

Envirogen and NX Filtration previously worked together on projects related to microfiltration for a beer filtration application and ultrafiltration for a large industrial water treatment project in the UK.

Billy Denyer, European CEO at Envirogen comments: “We are pleased to expand our cooperation with NX Filtration from previous engagements based on micro- and ultrafiltration to their direct nanofiltration membranes. This dNF membrane is used as a single-step replacement for multiple process stages, including coagulation, clarification, sand filtration, ultrafiltration and reverse osmosis. The system has a low chemical requirement and delivers significant energy savings, making it an excellent choice for surface water treatment, waste stream recycling and providing rejection of dissolved solids.”

Gerard Ruiter, sales manager at NX Filtration adds: “We are pleased to continue and further intensify our relation with Envirogen. Having started our cooperation in 2020 based on our micro- and ultrafiltration membranes, we are proud to now also supply our most innovative membranes based on direct nanofiltration technology. As such we can contribute to an efficient and sustainable water recycling process for this important project in the UK. Water recycling is a very powerful tool in managing companies’ water footprint. Globally we experience growing acceptance for this sustainable circular economy principle. Our dNF technology is perfectly suited for both municipal and industrial water recycling.”
