Global group in advanced hollow fibre membrane technology NX Filtration will supply its hollow fibre nanofiltration (HFNF) membrane modules to an indirect potable water reuse system in Mexico, marking NX Filtration’s largest project to date.

The project part of SAPAL’s Estaciones Regeneradoras de Agua (ERA), or water regeneration stations programme — aims to produce drinking water from the Desbaste wastewater treatment plant (WWTP), in an indirect potable reuse (IPR) scheme including HFNF and advanced oxidation technologies.

This water reuse concept is a step to address water scarcity in the region. The project will be executed in two phases with a capacity of 17MLD each, with the awarded contract covering phase 1. This marks another repeat project for NX Filtration, as SAPAL has already operated a smaller wastewater recovery project using its technology since 2022.

The application of HFNF membranes is cost-effective and largely chemical-free, as its large-scale water treatment contribute to enhanced water quality and environmental sustainability. NX Filtration CCO Alejandro Roman said, “This continuation of our collaboration with SAPAL and our Mexican partner EcoAzur underscores the importance of advanced membrane technology in addressing water challenges and creating a water positive future.”

The project is expected to be commissioned before the end of 2024. SAPAL’s intention is to subsequently release the tender for phase 2, doubling the capacity to further highlight the long-term impact and scalability of the project.
