Crossflow (CF) filtration is widely used for separating substances with poor filtration properties. As the method’s name implies, a crossflow of the feed continuously flows across the filter membrane in order to wash away material accumulations that clog the membrane pores. Nevertheless, conventional methods rely on a pump to adjust the feed overflow rate, which requires substantial energy, even for...

    In the chemical process industries (CPI), pressure is constantly on to improve filtration. The filtration step has to be performed quickly (time is money), efficiently (product loss is money lost), and effectively (energy costs for pumping and drying are soaring). As a result, vendors of filtration equipment — be it for dust removal from fluegas or product recovery from a gas or liquid...

    Improvements in cartridge dirt-holding capacity has led to new designs, as well as to new equations for filter selection and specification, which are linked to dramatic improvements in the time between turnarounds and filter changeout. Cartridge filtration serves the process industries in a host of applications. Ironically, however, filtration principles are not taught adequately in many...

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. The patented technology, developed by Yuefeng Xie, associate professor of environmental engineering at Penn State Harrisburg (Pa.; edlinks.che.com/6519-555), uses crumb rubber...

Manufacturing soda ash by either the Solvay or Hou process produces a large amount of waste sludge. About 10 m3 of waste — mostly liquid with 2–8 wt.% solids — is generated per ton of soda ash produced, says Trevor Sparks, marketing director, chemical process industries at Larox Corp. (Lappeenranta, Finland; edlinks.che.com/6516-537). The waste is composed of solid calcium carbonate and...
