A detailed follow up of the cations present in the wastewater of the Monsanto Europe site in Antwerp, Belgium, has led to an increased understanding of changing wastewater treatment plant performance. The chemical process industries' (CPI) other wastewater…
Pure water is an essential ingredient in the manufacture of a vast amount of products in the U.S. and, of course, throughout the world. In the industry for which I work, electricity generation, high-purity water is an absolute…
The rise of the salty water table in many areas of Australia is threatening a large area of agricultural land. In a two-year research, development and demonstration project, scientists have been looking for ways to solve the problem by producing…
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.…
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…
