For a biological denitrification process that selectively converts ammonia into nitrogen gas, Paques B.V. (Balk, Netherlands; edlinks.chemengonline.com/6891-536) was among the winners of the EEP environmental award, which was presented at Pollutec 2006 (Lyon, France; 28 November–December 1). Developed in collaboration…
Researchers from Pacific Northwest National Laboratory (PNNL; Richland, Wash.; edlinks.chemengonline.com/6519-554) and their collaborators have discovered that certain microorganisms can be stimulated to bind uranium from soil when served ethanol for an hour per day. The microbes could be used to…
The mountains of used tires piling up around the world may be a source of a new filtration media that promises to be a cheaper and more efficient alternative to sand or anthracite, which are commonly used for filtering wastewater.…
Ostara Nutrient Recovery Technologies Inc. (Vancouver, B.C., Canada; edlinks.chemengonline.com/6518-533) has constructed the first large-scale reactor to demonstrate the struvite recovery technology first developed by the University of British Columbia (UBC). The e700,000 reactor, located at the Edmonton Gold Bar sewage…
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.
