NX Filtration supplies advanced nanofiltration membranes for paper mill wastewater treatment

NX Filtration, a global leader in advanced membrane filtration technologies, has been selected by Lantania, the Spanish Infrastructure, Water and Energy Group, to supply its cutting-edge hollow fiber nanofiltration membranes for a wastewater treatment project at a paper mill. This project, currently under construction, marks a significant step towards achieving enhanced sustainability and compliance with strict water quality standards in industrial wastewater management.

The paper mill’s existing wastewater treatment plant faced challenges in meeting stringent COD (Chemical Oxygen Demand) discharge limits. As such, the wastewater treatment system required an additional step to ensure compliance. NX Filtration’s hollow fiber nanofiltration membranes were chosen for their exceptional performance in reducing COD levels effectively and efficiently.




The upgraded treatment system will integrate the hollow fiber nanofiltration membranes with existing technologies, including coagulation, dual sand-anthracite filtration, cartridge filtration, and activated carbon filtration. This innovative combination is designed to ensure superior water quality and operational reliability for the paper mill.

Lantania Water, the specialised water company of Lantania Group, has extensive experience in projects related to the integral water cycle such as desalination plants, urban and industrial water and wastewater treatment, and all types of hydraulic infrastructure. Have a team of experts in the design and implementation of both traditional biological solutions and specific processes more geared towards industry. Lantania Water covers the entire water cycle supplying turnkey EPC facilities and even in B.O.T. (Build, Operate and Transfer) mode, from the pilot plant study, process simulations, analytical campaigns, basic and detailed engineering, manufacturing and procurement of mechanical and electrical equipment to assemblies, start-up, operation and maintenance.
