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…
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…
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…
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…
Scaling, fouling and corrosion have long been the enemy of cooling-tower water. While these issues still present significant water-treatment hurdles, today’s processors are also dealing with “impaired” water streams and increasing restrictions affecting intake and discharge water, among other challenges.…
Last month at Aquatech China (Shanghai; June 5–7), this company introduced a new addition to its range of membrane-separation elements for reverse osmosis (RO)-based water treatment, namely, Low-Energy (LE) elements. Operating pressures of the LE elements are around 20 to…
There is an emerging crisis brewing for the chemical processing industries (CPI) in many regions of the world. Those regions include China, the world’s manufacturing powerhouse; swaths of the U.S., including large parts of its South; and chunks of Europe.…
