Salinity Solutions Ltd is a UK-based clean tech company pioneering a transformative approach to water purification. Founded on breakthrough research from Aston University and the University of Birmingham, the company is tackling global water scarcity with its patented Hybrid Batch Reverse Osmosis (HyBatch™) technology—an innovation poised to redefine the economics and sustainability of reverse osmosis (RO).

Traditional continuous flow RO systems, suffer from high energy demands, limited adaptability, and costly maintenance. Salinity Solutions’ HyBatch™ system replaces this model with intelligent batch processing, enabling precise control over pressure and flow during each cycle. This results in significantly reduced energy consumption, higher water recovery rates, and 30-50% lower operational costs.

Unlike conventional systems, HyBatch™ dynamically adjusts to varying feedwater conditions, maintaining consistent performance even with fluctuating salinity levels. This adaptability not only improves efficiency but also extends membrane life and reduces chemical usage—delivering both economic and environmental benefits.

The technology is compact, scalable, and versatile, with applications across municipal water reuse, industrial Zero Liquid Discharge (ZLD), brine minimisation, and lithium extraction. By reducing energy use and carbon emissions, HyBatch™ supports global sustainability goals while making clean water more accessible.

Backed by strategic partnerships and international licensing agreements, Salinity Solutions is rapidly expanding its impact. Pilots and commercial deployments in UK, France, Germany and India have demonstrated the system’s effectiveness in real-world conditions, from vertical farming, municipal reuse, ZLD to mineral recovery.

At the 2025 Desalination Technology Expo, Salinity Solutions Ltd invites you to explore how intelligent batch RO is reshaping the future of desalination—delivering smarter, cleaner, and more sustainable water treatment.
