For wastewater treatment, membrane bioreactors (MBRs) provide superior effluent quality in a small footprint compared to alternative activated-sludge treatment methods. However, MBRs are prone to fouling, and thus may require frequent membrane cleaning with the associated manpower and chemical costs. Microdyn-Nadir GmbH (Wiesbaden; www.microdyn-nadir.de), in cooperation with Darmstadt University (both...

Coal is typically cleaned by gravity separation to reduce ash and pyrite content, with flotation used to recover fines. Various methods have been applied to disperse fine clay particles from the surface of coal particles and thus improve coal flotation performance. A team of researchers from the Ian Wark Research Institute, University of South Australia (Adelaide; www.unisa.edu.au), has studied the effect...

With last month’s proclamation by President-elect Barack Obama that his administration would move to cut U.S. greenhouse-gas emissions, it appears that the U.S. may finally get in step with the 182 countries that have signed the Kyoto Protocol. Obama pledged to establish a cap-and-trade system with the goals of lowering emissions to 1990 levels by 2020, then reducing them an additional 80% by 2050...

When it comes to dust collection in the chemical process industries (CPI), there exists a wide variety of needs. For example, folks in dyes and pigments have a different set of dust collection challenges than those in the pharmaceutical industry, who have differing requirements from processors working with paints and varnishes. However, any and all chemical processors can boost process efficiency by...
