Desalitech says its water treatment system — located at the Dead Sea Works chemical plant in Israel — has cost and wastewater disposal advantage that can benefit manufacturing plants worldwide.
The company today said that Environmental Protection Technologies (EPT) of Israel will increase the production rate of its reverse osmosis (RO) water treatment system by 50 percent.
The closed circuit desalination (CCD) RO plant (pictured) designed by Desalitech is owned and operated by EPT and currently produces 100 gallons of purified water per minute to supply drinking water for an industrial compound and process water for pharmaceutical manufacturing.
Desalitech says the RO plant’s reliable performance spurred an increased demand for purified water at the site, leading to the planned expansion.
Low humidity and temperatures that regularly exceed 105 degrees Fahrenheit during summer contribute to limited water supplies in the Dead Sea region, where local industries must often rely on expensive deliveries by water trucks. The existing Desalitech RO plant has enabled EPT to use a brackish water source near the site, producing high-quality purified water despite high amounts of organic matter and minerals in the pond and the extreme variations in water chemistry, temperature and dust.
EPT CEO Yechiel Menuchin says Desalitech’s plant makes the maximum of scarce water resources while minimizing water-treatment costs.
EPT will begin offering Desalitech systems to other industrial customers around the world, the company says.
Changes in feedwater composition, temperature and membrane age could cause flux imbalance, premature membrane wear, loss of productivity and increased energy and operational costs for conventional RO systems. Desalitech says its system is able to operate at high recovery and automatically adjust for feedwater quality and provides natural resistance to scaling and fouling. These advantages can benefit other manufacturing plants, either as retrofits or a new product, the company says.
Earlier this year Desalitech supplied a water purification system to the Kittansett Club golf course in Marion, Mass., where wells at the course that have historically supplied essential irrigation water are being affected by accelerating seawater intrusion. The company’s CCD RO system will treat 100 gallons of well water per minute, varying from 1,000 to 10,000 parts per million of dissolved salts, Desalitech says.
