  • 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 ...

  • 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 ...
