Waste heat powered Forward Osmosis for waste water recycling/reuse and desalination

Waterwhelm currently has multiple projects for its waste heat powered forward osmosis (FO) water recycling/water re-use and desalination technology. Including with Veolia, Diageo, Northumbrian Water, and internationally. Waterwhelm uses waste heat, readily available at industrial sites, to treat waste water to the same quality as reverse osmosis (RO). The technology operates at low pressures (2-4 bar) and since it is powered by waste heat (14-28 kWh/m3), instead of electricity, our FO technology uses 80% less electricity and 35% less CAPEX than RO. Recycling wastewater / desalination at 0.3-0.5 kWh/m3, realising up to 79% reduction in CO2 emissions. The product water (recycled/desalinated) can be used as industrial water supply water to make industrial sites more self-sufficent in terms of their own water use. Waterwhelm is beginning to implement this technology across many industrial sites in 2025. The technology is applicable to any industrial site with waste heat and waste water/near seawater including hydrogen production sites (product water has been used with hydrogen electrolyser), power plants, chemical plants, refineries and offshore desalination. Waterwhelm can provide a pilot system, at cost, to demonstrate the technology to new customers, or it is now in position to offer a full scale commercial plant.
