Bohai Bay plant cuts desalination energy use by more than half
A large desalination plant in the Caofeidian industrial zone of Tangshan, Hebei province, has entered trial production.
It takes concentrated seawater left over from desalination and processes it into fresh water and refined salt.
The plant uses more than half as much electricity as before, according to the report.
For every tonne of refined concentrated seawater it produces, it also yields two tonnes of fresh water.
The salt has industrial value, and the process could offer a way to reduce the problem of discharging concentrated seawater into the sea.
The plant is at the trial production stage; no further steps are specified.
A desalination plant on Bohai Bay has cut electricity use by more than half while processing waste brine into industrial salt.
The facility is in the Caofeidian industrial zone of Tangshan, Hebei province.
It has recently entered trial production.
The process yields 1 tonne of refined concentrated seawater and 2 tonnes of fresh water for every 3 tonnes of waste brine processed.
The technology is presented as a way to address the challenge of discharging concentrated seawater into the sea.
