  • Bissell Point, Missouri - Trickling Filter installations applications - Case Study

    Bissell Point, the largest wastewater treatment facility in Missouri, expanded their facility in the mid-1980s to provide secondary treatment. The goal of the upgrade was to select a reliable process that would achieve high-rate BOD removal. They opted for trickling filter technology and worked with Brentwood to install roughly 3 million cubic feet of plastic media in 6 towers. Nearly 25 years ...

  • Case study - Filtration for Alcan (France) swarf recovery at an aluminium billet plant

    In 1998 this Glosfume ceramic filter system was originally installed at British Aluminium plant in the UK to filter oily fumes from an induction furnace smelting oily swarf recovered from billet sawing. The filter is injected with 2C talc before being recycled back to the inlet ducting. At a pre-set time, the talc is discharged to a collection drum and the cycle is repeated. During 2006 British ...

  • Warm Springs, GA Radium Removal - Case study

    The City of Warm Springs is a small community of approximately 500 residents located in central Georgia. In 2010, water testing found a radium level between 8 – 11 pCi/L and a Gross Alpha level of 25 pCi/L, both above state and USEPA drinking water regulations of 5 pCi/L and 15 pCi/L respectively. Engineering Management Inc (EMI) conducted a pilot test in late 2010 to test a manganese ...

  • Nature inspires a better way to block biofilms

    In many industries where equipment comes in contact with water, including those that rely on water treatment membranes, equipment fouling is a huge problem. Biofilm fouling occurs when living organisms — including bacteria, algae, and even mollusks — become attached to boat hulls, harbor structures, and other equipment. The resulting damage can be costly. Coatings and other chemical ...

  • How can you measure Peracetic Acid separately from Hydrogen peroxide, Isn’t there hydrogen peroxide in PAA?

    We receive questions of this sort frequently and the questioner is partly right. Peracetic acid (PAA) is formed in an equilibrium mixture with hydrogen peroxide and acetic acid, so in a mixture of PAA, hydrogen peroxide and acetic acid, PAA is being continually formed by the reaction of hydrogen peroxide and acetic acid, and peracetic acid is continually breaking down to reform hydrogen peroxide ...
