  • Ozone Brings Better Bottled Water

    The proliferation of bottled beverages worldwide and an increased awareness of consumer health issues have beverage bottlers rethinking how to keep their liquids safe for consumption. One problem they face is the need to deliver a product that is free of bacteria, to provide extended shelf life and product quality. Ozone has quickly become the disinfectant of choice among water bottlers ...

  • A clinoptilolite-PDMS mixed-matrix membrane for high temperature water softening

    A mixed-matrix membrane composed of polydimethylsiloxane (PDMS) as the continuous phase and clinoptilolite, a naturally occurring zeolite, as the active phase has been used to decrease the conductivity of water by more than 80% across the membrane. Testing was carried out using a cross-flow configuration at temperatures as high as 160 °C using a constant transmembrane pressure of 8 bar. The ...

  • Oil and Water Don’t Mix – But Can They Co-Exist? - A GLOBE-Net Editorial

    Real progress is being made to reduce the environmental impacts of oil sands activities. But that message is being lost in the flood of bad press about contamination of adjacent waterways and the concerns about those ugly tailings ponds. Oil and water do not mix. But can they co-exist? GLOBE-Net, September 1, 2010 - August has not been a good month for the Alberta oil sands industry. The tidal ...

  • Flocculation of Cu, Zn, Pb, Ni and Mn during mixing River Water with Caspian Seawater

    Rivers are the major transporting means for dissolved and particulate matter from the continents into the seas and lakes (Meybeck, 1988). Dissolved metals come into the particulate phase due to flocculation processes during estuarine mixing (Eckert and Sholkovitz, 1976; Sholkovitz, et al., 1977 and Boyle, et al., 1977). Many investigations have been carried out on ...

  • Finding Breathing Room - New aeration/mixing system manages tight nutrient limits, tight footprint

    Problem: Not enough capacity and an inability to meet stringent effluent limits for phosphorus. Solution: Installing combined mixing and aeration technology, as well as an automated control system. Aeration Industries International's Tri-Oval system enabled the city of Heyburn, ID to meet tight effluent requirements and increased loading on a small footprint and ...

  • Case study - Supplemental aeration nearly eliminates filamentous sludge bulking

    The Dubai Investments Park Wastewater Treatment plant in the United Arab Emirates faced challenges in their oxidation ditch due to filamentous sludge bulking, resulting in poor sludge settling in the secondary clarifier. Supplemental aeration was needed to eliminate the filamentous sludge bulking. Challenge: The oxidation ditch is treating an ...

  • The design of static mixer heat transfer equipment for adhesives, sealants, resins and polymers.

    The fluids handled within the adhesives and sealant industries are amongst the most difficult to handle of any in the main process industries globally. The characteristics which make them particularly difficult to handle include: High viscosities (typically 1-2000 Pa.s, or 1000 to 2 million cP). Often non-Newtonian (viscosity is not constant and varies with shear rate). Some ...

  • Energy from waste: the recycling of limed fleshings

    Leather products have been around a long while - there are those who claim that it is the second oldest business in the world. Going back a few millennia, when our earliest ancestors decided that sitting on hard rock was not a soft option, they turned to other materials in order to create more comfortable seating, as well as warmer bedding and improved clothing. Animal skins became the fabric ...

  • The principles of aeration and mixing utilizing process aerator technology

    Aeration and mixing are necessary elements for aerobic biological wastewater treatment processes to maintain a healthy, stabilized biological population and thus, insure optimal treatment of the wastewater assuming there is adequate contact time and substrate available. In the design of wastewater treatment plants, aeration typically involves supply of both oxygen and mixing. Aeration is a large ...

  • Valuable product production from wood mill effluents

    Fibreboard production is one of the most important industrial activities in Galicia (Spain). Great amounts of wastewater are generated, with properties depending on the type of wood, treatment process, final product and water reusing, among others.
