Desalitech Says Dead Sea Works Desalination Rate to Rise 50%Rachel Layne
Desalitech Inc., a developer of desalination and industrial water-treatment technologies, is increasing the production rate of Dead Sea Works Ltd.’s reverse-osmosis system by 50 percent.
Desalitech, founded in Israel and based in Newton, Massachusetts, said today that the closed-circuit plant it designed for the Dead Sea unit of minerals harvester Israel Chemicals Ltd. now yields 100 gallons of purified water per minute for drinking water and pharmaceutical manufacturing.
The closed-circuit reverse-osmosis system, run by Environmental Protection Technologies Ltd. of Israel, purifies brackish water that’s been clogged with algae and solids near the site including debris from the desert, Rick Stover, a Desalitech executive vice president, said by e-mail. EPT will start offering the system globally. Terms weren’t disclosed.
The expansion will help Desalitech tap a desalination market expected to reach $22 billion by 2018, double the current market, according to International Desalination Association estimates. About 60 percent of current desalination capacity is for seawater and 21 percent for brackish waters.
In reverse osmosis, water is forced by pressure through semi-permiable membranes, leaving behind dissolved and particulate materials. In a closed circuit system, batches are put through the system without stopping pumps using a lower average membrane feed pressure and less energy consumption, according to Desalitech.
“Desalitech’s high-recovery water systems provide a better solution in challenging conditions” than traditional reverse-osmosis, Yechiel Menuchin, EPT’s chief executive officer, said in the statement.
