June 14, 2024

ENOWA and Nanostone Water, Inc. (NSW) are pleased to announce an agreement to collaborate on the application of Ceramic Ultrafiltration Membrane for Brine Mining in NEOM, located in northwest Saudi Arabia. The signing ceremony of a Memorandum of Understanding (MoU) will take place during the prestigious Singapore International Water Week (SIWW), held from June 18 to 22, 2024.

This partnership marks a significant step towards advancing sustainable water solutions and transforming desalination brine waste into valuable resources. The MoU outlines the collaborative efforts of ENOWA and NSW to develop and implement Ceramic Ultrafiltration (CUF) technology for brine mining, an important component of ENOWA’s circular economy strategy.

The MoU will focus on a one-year pilot testing of CUF membranes to harvest minerals and metals from desalination and cooling tower blowdown brine. This project aims to create a revenue stream while developing an environmentally sustainable method of managing desalination waste. Successful pilot results will pave the way for scaling up the design for commercial facilities.
