NX Filtration - Food&Beverage

NX Filtration is a provider of direct nanofiltration (dNF) membranes that retain micropollutants (including pharmaceuticals, medicines, PFAS and insecticides), color and selective salts, but also bacteria, viruses and nanoplastics, from water in a one-step process, requiring less energy and less chemical dosing compared to traditional membrane technologies. NX Filtration also offers ultrafiltration (UF) and microfiltration (MF) membranes.

The Product Star award underscores NX Filtration's achievements in delivering innovative and sustainable solutions for water treatment, and marks the high appreciation for its breakthrough hollow fiber nanofiltration (dNF) membrane technology by the Chinese water industry.

dNF membranes are specifically suited for micropollutant removal, and provides a sustainable and energy-saving approach for efficient clean water production. NX Filtration is honored to receive this prestigious recognition and will continue to drive advancements in the water sector, contributing to a sustainable and cleaner future.

Also at the conference renowned and listed system integrator GreenTech announced the successful validation of their intelligent coagulation and dNF membrane based treatment process “GTMOST”. The efficient GTMOST water treatment process received unanimous acclaim from the Review Board of water treatment technology experts; GTMOST offers a safe, intensive, efficient, and intelligent solution for high-quality drinking water production using surface water as the water source, and on top it holds substantial technical and economic added value. The experts strongly encouraged Greentech to advance and prompt start the engineering and construction of the full scale treatment plant, and widespread promote this innovative solution.

About Desalination Branch of China Water Enterprises Confederation (DBCWEC)
Desalination Branch of China Water Enterprises Confederation (DBCWEC for short) is the branch of Water Enterprises Confederation and voluntarily grouped by the enterprises and public institutions who are engaged in desalination and water treatment industry and is a non-profitable association.
The goals of the Association will be the development and promotion of the appropriate use of desalination and desalination technology world-wide in water supply, water reuse, water pollution control, water purification, water treatment, and other water sciences and technology. We have about 350 members. The Association is managed and supervised by Water Enterprises Confederation, other relative confederation of Ministry of Water Resources and Ministry of Civil Affairs.

In Melbourne, Florida, Jacobs Engineering, Harn RO, and NX Filtration teamed up to prove these sustainability claims through extensive testing with a full scale demo unit against traditional technologies as microfiltration plus spiral wound nanofiltration (MF+SWNF) and advanced oxidation plus granular activated carbon (AOP+GAC). The Melbourne Water Treatment Plant draws surface water from Lake Washington, which experiences high organic content during summer and turbidity spikes caused by rainfall and lake turnover events in winter. The perfect place for this demonstration.

Only a 200-micron strainer was used as the only pre-treatment before the dNF membrane. The demo system was provided by NX Filtration and designed by Harn R/O Systems, with Jacobs as the testing entity. We demonstrated stable flux and effective removal of contaminants, making it a viable option for water treatment. dNF exhibited lower capital costs and operating costs compared to the alternative treatment options. The NPV analysis indicated a 9% and 22% lower cost for HFNF compared to MF+SWNF and upgrading the existing AOP+GAC process, respectively. Future designs with an increased dNF skid size are expected to further decrease capital and operating costs even further, making dNF the most sustainable, cost-effective and efficient solution for water treatment.

GJ Schers, Project Manager of Jacobs Engineering, stated:
“We are very pleased to see that our first pilot with NX Filtration’s direct nanofiltration technology has been very successful. We achieved stable operations at each different recovery tested. We realized a high operational recovery of 85%, minimizing water waste. The permeate produced was of excellent quality, particularly for colour, DOC, sulphates, and turbidity, while allowing monovalent ions to pass through. The full-scale system will be further optimized for sufficient hardness removal to improve compliance with the Lead and Copper Rule. ”

Tony Fuhrman, NX Filtrations Country Manager Americas adds:

"NX Filtration's dNF membranes offer sustainable surface water treatment, proven through collaboration with Jacobs Engineering and Harn RO in the USA. With excellent micropollutant retention, low energy consumption, and minimal chemical dosing, our membranes outperform traditional methods. The Melbourne demo showcased stable flux, effective contaminant removal, and lower capital and operating costs compared to alternatives. Our dNF technology is the most sustainable, cost-effective, and efficient solution for water treatment."

Our direct nanofiltration (dNF) membranes offer the unique combination of a low fouling hollow fiber configuration with the ability to remove organics and salinity (hardness) from water in one simple step. Other than a strainer, no further pre-treatment is required. We manufacture our membranes with a patented layer-by-layer process, where multiple nano-scale layers are deposited on a membrane support. This method enables very precise and controlled rejection and flux properties of the membrane.

Compared to conventional pretreatment, HYDRAcap™ allows for higher fluxes for RO and NF systems while maintaining longer intervals between cleanings. In some cases it replaces conventional pretreatment for potable applications, ground water recharging and water recycling.

HFNF membranes effectively remove over 95% of organic compounds, microbes, and certain heavy metals with minimal pretreatment, eliminating the need for coagulants or other chemical additives. This chemical-free operation significantly reduces environmental impact and simplifies waste management. Additionally, the technology is energy-efficient, reducing operational costs while maintaining high production capacity.

The future is now: chemical-free water treatment

This project, part of SAPAL’s ERA (Estaciones Regeneradoras de Agua, or Water Regeneration Stations) program, aims to produce drinking water from the Desbaste wastewater treatment plant using an indirect potable reuse (IPR) scheme that incorporates HFNF and advanced oxidation technologies. This water reuse concept is a crucial step to address water scarcity issues in the region. The project will be executed in two phases, each with a capacity of 17 million liters per day (MLD).

Chemical-Free Water Treatment

HFNF offer a chemical-free, energy-efficient solution for water reuse and desalination, removing over 95% of impurities with minimal pretreatment.
