  • Rolled Filters Move Filtration in a New Direction

    When selecting filtration technology, industrial users have long wrestled with the tradeoffs of dirt-holding capacity versus particle selectivity or quick-and-dirty change-outs versus process time. For many applications, a self-contained rolled filter offers an effective solution to both problems. Constructed with polypropylene hardware and various media in a spiral-wound design, rolled filters ...

  • The Dangers of Hydrogen Sulfide and Filtration with Activated Carbon

    Hydrogen sulfide (H2S) is a poisonous, highly flammable, colorless gas that is associated with a ‘rotten egg’ odor. As stated by cchealth.org, “hydrogen sulfide is created naturally by decaying organic matter and is released from sewage sludge, liquid manure, and sulfur hot springs.” It also is a by-product from industrial processes such as natural gas processing, ...

  • Dewatering waste-activated sludge using dissolved gas-flotation followed by filtration

    After the successes of flotation of waste-activated sludge (WAS), using the new technique utilizing CO2 gas as well as using model gas (80% N2+20% CO2) in previous research because of the high water solubility of CO2 gas, the aim of this study is to develop a simple method for dewatering WAS for easier reuse and safe disposal. The paper introduces a laboratory model for dewatering WAS in two ...

  • Using Biological Filtration to Remove Arsenic from Drinking Water

    In 2001, the U.S. Environmental Protection Agency changed the standards for arsenic levels in drinking water. At that time, the agency had estimated that more than 36 million Americans were drinking water that contained arsenic levels at or above 3 parts per billion. A new standard was set, lowering the maximum contaminant level to 10 parts per billion (ppb) from the previous standard of 50 ppb. ...
