The Aporia · Chinese desalination plant cuts 60% energy use by turning waste brine into industrial salt

A Chinese desalination plant in Caofeidian industrial zone, Tangshan, Hebei province, has begun trial production and uses technology that reduces energy consumption by 60% while converting waste brine into industrial salt. The facility processes seawater at a ratio where three parts of waste brine produce one part of refined concentrated seawater with 120 grams per liter salinity and two parts fresh water. This innovation addresses the global issue of discharging highly saline by-products from desalination plants into the ocean.

Story summary

A new desalination plant in Tangshan, Hebei province in China has started its trial production stage and is reported to cut energy use by 60% compared to conventional plants. Situated in the Caofeidian industrial zone, the facility processes waste brine at a three-to-one ratio, producing 1 tonne of refined concentrated seawater (with salinity of 120 grams per litre) and 2 tonnes of fresh water simultaneously. This innovative technology could address the global issue of discharging highly saline by-products back into the sea, offering a more sustainable solution for desalination waste management.
