Industrial water
The NX Filtration membrane portfolio includes Hollow fiber nanofiltration- (NX Nano), ultrafiltration (NX Ultra) and microfiltration (NX Micro) solutions for various applications in the food and beverage, textile, pharmaceutical and paper industries.
Industrial water
Securing water supply is of high importance for many industries. Whether for use in breweries, pulp & paper, textile, electronics, pharmaceutical or cooling tower applications; water is indispensable. To put this into perspective, industry accounts for about 40% of total water abstraction globally. Many industries are located in water-scarce parts of the world, and more than two-thirds report on exposure to water risks for their business.
With our hollow fiber nanofiltration (HFNF) technology, we enable:
- treatment of surface water and well water to remove color, humic acids, dissolved solids, organics, micro plastics and micropollutants;
- wastewater reuse for industrial processes or preventing discharge of polluted wastewater;
- recovery of valuable raw materials from wastewater streams, such as indigo in the textile industry or cleaning chemicals such as caustic in breweries.
Industrial wastewater treatment and reuse
Treatment of wastewater can significantly reduce discharge costs and bring the discharge within compliance. Wastewater is becoming a valuable resource in many regions around the world and wastewater reuse will reduce the water footprint by reducing the raw water intake. Biologically treated waste water effluent is an excellent water source to treat with our direct nanofiltration membranes. In many cases waste water streams can also be treated directly with hollow fiber nanofiltration, resulting in a very compact and efficient reuse process.

Surface water treatment for process water
Due to increasing water stress and high cost of drinking water, alternative sources increasingly come into play for process water in myriad industrial processes including surface water, well water and rain water. Our hollow fiber nanofiltration membranes convert these water sources into drinking water quality, enabling efficient process water preparation whilst enabling significant savings in energy usage and chemical consumption in comparison to traditional membrane technologies.

PFAS removal
Water contaminated with per- and polyfluoroalkyl substances (PFAS) poses a public health and environmental risk. Most conventional water treatment plants are not suited for PFAS removal. Our hollow fiber nanofiltration membranes offer an effective and efficient barrier for different PFAS molecules and can be integrated into processes to produce safe and PFAS free water, or for remediation of contaminated water sources.

CIP recovery
In most industries efficient Clean-in-Place (CIP) systems are implemented for cleaning of process equipment, producing large amounts of chemically contaminated wastewater. By applying our direct nanofiltration membranes, these costly chemical solutions can be regenerated efficiently for direct reuse in the process resulting in significant savings on chemicals. The recovery of concentrated and alkaline solutions offers significant sustainability benefits and reduced cost for many process industries, including the food and beverage industry. Our hollow fiber nanofiltration membranes (NX Nano) have an excellent stability at extreme pH levels. This unique property enables the recovery of solutions of sodium hydroxide.

Cooling water blowdown water recycling
Cooling tower make-up water; the water level in the cooling tower has to be controlled and managed by adding makeup water in order to account for loss of water due to evaporation, blow down and mechanical carryout of water droplets (drift) during operation of cooling tower. Hollow fiber nanofiltration is the go to membrane technology for recycling of the blow down water, thus saving water in an efficient and sustainable way.
Dye recovery
The textile industry produces large quantities of wastewater in various stages of the production process such as dyeing and washing. The effluent emerging from these processes contains contaminants such as dyes, detergents and fixing agents, which are both costly and damaging to the environment. Hollow fiber nanofiltration membranes can be used to treat the effluent wastewater enabling the concentration and recovery of the dyes.

F&B applications
Incoming water streams can be optimally tailored for the production of high-quality food and beverage products with hollow fiber nanofiltration membrane technology. This includes the removal of unwanted organics, micropollutants, color, viruses and bacteria, iron and heavy metals in a robust one-step process, while maintaining the mineral balance of the water. In addition, wastewater from e.g. cleaning (CIP) and utilities can be treated efficiently and recycled.
