Waste heat powered Forward Osmosis for water re-use and desalination

Waterwhelm has developed a patented Forward Osmosis (FO) technology for water reuse and desalination, validated through our pilot plant at a Veolia Wastewater Treatment Works, in Seafield, Edinburgh. The technology operates at low pressures (2-4 bar) and is powered by waste heat, therefore, in comparison with reverse osmosis (RO), our FO technology uses 80% less electricity and 35% less CAPEX, realising a significant reduction in CO2 emissions. The product water can be used as potable or industrial water supply. Waterwhelm will implement this technology across many wastewater treatment and desalination sites, and other sectors such as hydrogen production, power plants, chemical plants and refineries, to utilise waste heat in the context of zero-waste, circular economy and contribute to achieving net-zero emissions globally.
