Led by: Waterwhelm, partnered with AtkinsRealis
A new technology for desalination and water re-use that operates at low pressure, resulting in lower capital and maintenance costs. Powered by waste heat, this circular solution achieves the lowest-ever rate of electricity consumption and CO2 emissions. Waterwhelm has developed a game-changing forward osmosis (FO) technology for desalination of brackish and sea water to potable water, as an alternative to reverse osmosis (RO). The technology is powered by waste heat, therefore in comparison with RO uses 80% less electricity, 35% less CAPEX with a 79% reduction in CO2 emissions. Through this project, Waterwhelm will design a prototype for utilising low-grade waste heat sources at wastewater treatment works and assess its applicability/viability by engaging with the water sector. This will subsequently lead to a new desalination method enhancing circular economy approaches and reducing emissions/costs in the water sector.
Waterwhelm was announced as one of 10 winners in the Water Discovery Challenge on 20 February 2024 – read more in the announcement blog.
