Scientists from the University of Illinois at Urbana-Champaign (edlinks.chemengonline.com/6517-551) have developed a catalyst that uses hydrogen to efficiently destroy harmful perchlorate in contaminated groundwater. The catalyst is composed of palladium and rhenium supported on activated carbon. The rhenium removes an…
Water is an essential resource for the chemical process industries (CPI), with steam, cooling water and process water as just a few examples of its many applications. When readily available, this essential commodity is often taken for granted.…
Ecovation, Inc. (Victor, N.Y.; edlinks.chemengonline.com/6516-539) has constructed a waste-treatment and renewable-energy-production facility for CoolBrands International (North Lawrence, N.Y.) — a cottage-cheese and yogurt production plant that will use Ecovation’s patented Mobilized Film Technology (MFT) to biologically treat wastewater containing cheese…
The U.S. DOE estimates that uranium contaminates more than 2,500 billion liters of groundwater nation wide; for the past 10 years, the agency has supported research into the ability of naturally-occuring microbes that can stop the underground migration of uranium…
The world’s increasing demand for water brings with it technological challenges as well as opportunities for the chemical process industries (CPI). Recent forecasts show that the need and opportunities for water treatment are on the rise and will…
Dow Chemical Co. (Midland, Mich.; edlinks.chemengonline.com/6515-546) has acquired Zhejiang Omex Environmental Engineering Co., Ltd. (OEE; Huzhou, Zhejiang, China). The acquisition will enable Dow to expand its water-purification offerings into three component technologies: ultrafiltration, membrane-bioreactor (MBR) membranes and electrodeionization.
Battelle (Columbus, Ohio; edlinks.chemengonline.com/5830-544) has licensed the Samms technology, developed at Pacific Northwest National Laboratory (PNNL; Richland, Wash.), to Steward Environmental Solutions (Chattanooga, Tenn.; edlinks.chemengonline.com/5830-545). Samms (self-assembled monolayers on mesoporous supports) is a technology that can be tailored to selectively…
Researchers at the Lawrence Livermore National Laboratory (LLNL; Calif.; edlinks.chemengonline.com/5830-551) have constructed a membrane of carbon nanotubes (CNTs) on a silicone chip, which has the potential to reduce the energy costs of desalination by up to 75%, compared to conventional…
Continuously measure chlorine in water The Model TCL (photo, upper left) is a complete system for the measurement of total chlorine in water. Comprised of a sample conditioning system, an analyzer and a sensor, this system provides continuous measurement and…
Vortex Corp. (Prescott, Ariz.; edlinks.chemengonline.com/5828-538) has been awarded a Phase Two, $750,000 Homeland Security Advanced Research Project Agency Small Business Innovation Research contract to develop chlorine-free water-purification systems for municipal water-treatment plants.
