Dow Water & Process Solutions Unveils New Electrodeionization Technology
New module aims to lower operating costs by up to 15% for electronics manufacturers, refineries, chemical operations and power generation facilities
Dow Water & Process Solutions (DW&PS), a business unit of The Dow Chemical Co. and its consolidated subsidiaries (Dow) and a global supplier of advanced technologies for purification and separation processes, announced at Singapore International Water Week (SIWW) that the next generation of its electrodeionization (EDI) product for industrial water treatment is available globally. The Electrodeionization 310 module aims to lower operating costs by up to 15% for electronics manufacturers, refineries, chemical operations and power generation facilities, and has been named one of SIWW’s top innovations.
“Dow EDI modules optimize performance, maintain continuous product quality and can produce up to 18 megaohm-cm of water for high-purity and industrial water applications,” said Lance Johnson, global commercial director for Dow Water & Process Solutions. “The Dow Electrodeionization 310 module incorporates this product performance into an advanced design that minimizes system complexity and shrinks the overall system footprint.”
The 310 module eliminates the need for a brine recirculation loop, lowering both capital and operating costs, Dow said. Dow also offers spiral-wound EDI, a design innovation that aims to simplify maintenance, decreases module weight and increases system design flexibility for OEMs.
“Lower operating expenses and maintenance requirements make EDI a cost-effective solution for many plants,” said Chris Sacksteder, strategic marketing manager for industrial water, Dow Water & Process Solutions. “At Dow, we’re further developing EDI so that industry can benefit from the environmental, reliability and performance advantages it offers.”
In addition to the Dow Electrodeionization 310, Dow is utilizing SIWW to launch version 7.2.1 of ROSA design software for systems using reverse osmosis and nanofiltration. ROSA 7.2.1 is upgraded to more accurately predict ammonium and nitrate rejection rates, better represent the effect of operating conditions and to enable multiple simulations with incremental temperature and flow factors.
