  • 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 ...

  • 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 ...

  • Comparison of the water purification efficiency of two different flocculation-sediment-filtration (FSF) processes in Chaohu Lake in China

    A novel biofilter (BF) with the potential to improve pollutant removal when used as a substitute for sand filters in water purification processes is presented. To investigate BF's pollutant removal performance, a flocculation-sediment-biofiltration (FSBF) process was compared with a flocculation-sediment-sand filtration (FSSF) process on a lab scale, with water collected from Chaohu Lake. The ...

  • 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 ...

  • Fabrication of sulfated nanofilter membrane based on carboxymethyl cellulose

    The aim of this study is to prepare sulfated carboxymethyl cellulose (SCMC) nanofilter membrane using sulfur trioxide pyridine complex (SO3/pyridine) as sulfating agent and glutaraldehyde (GA) as a crosslinking agent onto polysulfone supporting membrane. The prepared nanofilter was characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, atomic ...

  • Treatment of petrochemical secondary effluent by an up-flow biological aerated filter (BAF)

    In this study, petrochemical secondary effluent was treated by a 55 cm diameter pilot-scale biological aerated filter (BAF) with a media depth of 220 cm. Volcanic rock grains were filled as the BAF media. Median removal efficiency of chemical oxygen demand (COD) and ammonia nitrogen (NH3-N) was 29.35 and 57.98%, respectively. Moreover, the removal profile of the COD, NH3-N, total ...

  • Recycling Using Antifreeze with Electrodionization

    Recycling used antifreeze makes sense for two reasons: 1) It is cost-effective, and 2) It saves resources. Ethylene glycol, the primary active ingredient in antifreeze, is produced from natural gas, which is a finite, non-renewable resource. For businesses that use a lot of antifreeze, like automobile repair shops, setting up an antifreeze recycling program can significantly reduce management ...
