Water scarcity is one of the most serious global challenges of our time. Desalination and water reuse are effective and reliable means to provide new water resources. Among the many methods available to treat water, reverse osmosis (RO) has widely…
With the C-XI decanter series, sewage treatment plants can achieve higher dry-substance values, saving money on disposal and further processing, says the company. The new decanters are said to offer optimum conveying of solids, greater purity of the liquid phase,…
The world’s largest environmental technology trade show, IFAT (www.ifat.de), takes place in Munich May 5–9. A record of nearly 3,000 companies from 50 countries are presenting innovations and services in water, sewage, waste and raw materials management, covering some 230,000…
The new software package, Ocean, can contribute to turning a sewage treatment plant from a disposal facility into an opportunity to generate electricity, recover resources and recycle water. For example, Ocean can identify energy-saving solutions and change wastewater treatment from…
Remox — the latest addition to this company’s Aquamove fleet of mobile water treatment solutions — is a membrane degasser that removes carbon dioxide and oxygen from water. The first membrane degasser available on the rental market, Remox is housed…
Currently, there are around 13,000 desalination plants in operation or under construction in 150 countries, according to the Institution of Chemical Engineers (IChemE; Rugby, U.K.; www.icheme.org). A number of these plants are in, or are planned for, locations that might…
Chemical, pharmaceutical and related industries produce large amounts of wastewater in their production and cleaning processes. The wastewater characteristics are often diverse, and may include minimally biodegradable or toxic substances, or both. To protect the environment, these wastewaters typically must…
This company’s Bio-Cell sheet, which makes up the core of its Bio-Cell MBR (membrane bioreactor) module, has a self-healing mechanism. Due to its sandwich-like and self-supporting structure, the membrane “heals” itself, even though it might be damaged by deep scratches,…
The pending water shortage I thank you for the exciting editorial titled The pending water shortage in CE, June 2013 [p. 5]. I fully agree with you that voluntary efforts are needed immediately to do everything possible to drastically bring…
Researchers from the University of Texas at Austin (www.utexas.edu) and the University of Marburg (Germany; www.uni-marburg.de) are developing a process, called electrochemically mediated seawater desalination, that promises to be an inexpensive way to desalinate small volumes of water. The patent-pending…
