For many years, reverse osmosis (RO) has been the backbone of water treatment and desalination, helping industries and utilities transform saline and contaminated water into a valuable resource. It remains one of the most widely deployed water treatment technologies in the world and has played a critical role in addressing growing global water demand.
Yet the challenges facing industry today are changing. Water scarcity is increasing, regulations are becoming more stringent, energy costs remain volatile, and businesses are under pressure to improve both environmental and economic performance. Against this backdrop, the opportunity for innovation is enormous.
The global water and wastewater treatment market was valued at more than £280 billion in 2025 and is projected to exceed £535 billion by 2034*, driven by increasing water scarcity, industrial demand and tighter environmental regulations.
At Salinity Solutions, we believe the next major step forward in membrane technology is HyBatch™ hybrid batch reverse osmosis, hailed as one of the biggest developments in 50 years.
Unlike conventional RO systems, which operate continuously at maximum pressure, HyBatch uses a patented batch process that dynamically controls pressure and concentration throughout a treatment cycle. By working with the natural osmotic properties of water, rather than constantly fighting against them, HyBatch can deliver significant improvements in efficiency and performance.
The benefits are compelling:
• Water recovery rates of up to 95%, enabling operators to recover more water from challenging streams.
• Energy savings of up to 50% compared with conventional RO.
• Lower operating costs through reduced energy consumption by up to 30% and extended membrane life.
• Reduced chemical consumption, helping simplify operations and minimise environmental impact.
• Improved handling of difficult waters containing high levels of silica and other scaling compounds.
These advantages become particularly important in industries where water is both a critical resource and a growing cost.
Across a wide range of industries, organisations are under increasing pressure to reduce freshwater consumption, increase water reuse and improve sustainability. In sectors such as food and beverage, chemicals, pharmaceuticals, textiles and agriculture, higher water recovery can help lower operating costs while reducing environmental impact.
In semiconductor manufacturing, where ultra-high-purity water is essential, even small improvements in recovery rates can deliver significant cost savings. The rapidly expanding data centre sector is also driving demand for advanced water treatment technologies as operators seek to reduce water consumption and meet sustainability targets.
Medical, pharmaceutical and life sciences facilities require high-purity water for critical processes, creating opportunities for technologies that maximise water recovery while maintaining stringent quality standards. Mining and power generation operations face similar challenges, particularly when managing saline water streams and silica-related scaling issues.
Agriculture, which accounts for the majority of global freshwater withdrawals, is increasingly adopting water reuse and desalination technologies to improve water security, particularly in regions affected by drought, water stress and declining groundwater resources.
Municipal water utilities are also looking for more efficient solutions as they contend with population growth, increasing water scarcity, drought and ageing infrastructure. Together, these drivers are creating a growing global market for technologies that can recover more water, reduce waste and improve resilience in water-intensive operations.
HyBatch also can play a major role in Zero Liquid Discharge (ZLD) systems. By recovering more water before downstream treatment, the technology can reduce the volume requiring further processing, lowering overall system costs and improving project economics.
As water resources become increasingly stressed around the world, the ability to extract more value from every litre of water will become a competitive advantage. Technologies that reduce energy use, increase recovery rates and improve sustainability are no longer optional. They are becoming essential.
That is why HyBatch is more than an incremental improvement to conventional reverse osmosis. It represents a smarter approach to water treatment, helping industries and utilities achieve greater efficiency, resilience and sustainability while addressing one of the world’s most pressing challenges.
An investment in Salinity Solutions will help bring the next generation of water treatment technology to a global market.
