Desalination pours more toxic brine into the ocean than previously thought

Desalination pours more toxic brine into the ocean than previously thought

Depending on location and type of technology, desalination alone can cost between $0.50 and over $2 to produce 1,000 liters of drinkable water — about what two people in the United States use in a day. Further evaporating the brine waste only increases the cost.

Modern desalination technologies, such as graphene oxides, are becoming more cost effective and releasing less brine discharge (SN: 8/20/16, p. 22). But they are not universally distributed and are uncommon in the Middle East where desalination is most used. “We need to make sure that with our efforts, we are able to use more of those types of technology which produce more desalinated water than brine,” Qadir says.
