RecovOAR™
Osmotically Assisted Reverse Osmosis
Chlor-Alkali & Soda Ash Production
Embrace an advanced low-energy brine concentration technology engineered to address the critical challenges of the chlor-alkali and soda ash industries. This innovation enhances operational reliability, streamlines processes, and optimizes costs, while supporting the key objectives of minimum liquid discharge (MLD) and zero liquid discharge (ZLD).
The chlor-alkali and soda ash industries heavily rely on external salt and water to prepare brine, largely due to inefficient on-site brine management. This dependency increases operational costs and creates additional transportation and logistics challenges, along with complexities regarding hardness removal. Rising regulatory pressure and growing water scarcity further complicate effective brine minimization.
To address this critical need, RecovOAR™, developed by Aquatech and FTS H2O, offers an advanced, low-energy brine concentration solution based on osmotically assisted reverse osmosis (OARO), enabling efficient resource recovery and water reuse.
Unlike conventional RO systems, RecovOAR™ is specifically designed to maximize water reuse, significantly reduce brine volumes, produces on-site high purity NaCl brine, and support zero liquid discharge/minimum liquid discharge goals. The process achieves brine concentration levels of up to 250 g/L TDS, while consistently producing high-quality permeate water.

Brine Mining Solutions
Case Study
Learn how RecovOAR helped one of the largest seawater desalination hubs at Saudi Arabia’s Al-Jubail to produce sodium chloride locally from concentrated seawater. The facility produces over 1.4 million m³/day of potable water, along with a massive volume of high-salinity brine. Traditionally discharged back into the sea, this brine represents a lost opportunity for resource recovery. With the implementation of RecovOAR, the plant consistently delivered a recovery rate of 75-78%, producing 0.5 m³/h of high-purity brine and achieving a 5.7-fold reduction in volume, with an energy consumption of 4.5 kWh/m³ of processed brine. Reduced OPEX and CAPEX significantly.
