NX Filtration Expands World's Largest HFNF Plant in Mexico

NX Filtration has received a repeat order to supply its hollow fiber nanofiltration (HFNF) modules, effectively doubling the capacity of the world’s largest HFNF facility in Mexico. The plant forms part of a water reuse initiative led by SAPAL (Sistema de Agua Potable y Alcantarillado de Leon) and implemented through distributor EcoAzur.

Developed under SAPAL’s Estaciones Regeneradoras de Agua (ERA) program, the facility treats municipal wastewater using a combination of HFNF and advanced oxidation technologies. The project delivers indirect potable reuse (IPR), transforming treated wastewater into drinking water. With this second phase, following an initial order in 2024, the facility will reach a total capacity of 34 million liters per day.

Alejandro Román, Chief Commercial Officer, NX Filtration, described the new order as a key milestone in the company’s collaboration with SAPAL and EcoAzur. “It underscores the importance of advanced membrane technology in addressing water challenges,” he said. Fernando Cortés, Managing Director, EcoAzur, added that the project sets a benchmark for future water reuse initiatives in Mexico and globally.

The project aligns with NX Filtration’s broader strategy of providing sustainable, largely chemical-free filtration solutions to address global water scarcity. The company’s membranes allow for efficient water recovery by removing contaminants while reducing energy use and chemical dependency compared to traditional treatment methods.

According to NX Filtration’s interim financial results for the first half of 2024, revenue rose 57% year-over-year, driven by the conversion of pilot projects into full-scale deployments and by repeat orders—highlighted by the largest order in the company’s history, related to the Mexican plant’s initial 17 million liters per day capacity in phase one.
