  • Low Energy Biological Nitrogen Removal by Cation Exchange, Thin Film Oxygen Transfer, and Heterotrophic Nitrification in Sequencing-Batch, Packed-Bed Reactors

    Sustainable solutions for biological nitrogen removal (BNtR) in wastewater require new treatment process concepts to lower energy requirements. A novel configuration of six packedbed, flood and drain (PFAD) reactors were used in a pilot study to remove nitrogen from a manufactured wastewater comprised of urea, cheese whey, and well water. The reactors operated in a sequencing-batch manner in ...

  • Recycling and use of wastes/co-products from the iron/steel and alumina industries

    The current and potential uses for Blast Furnace (BF) slag, steel slag and red mud, and their environmental implications, are outlined and discussed as are the difficulties associated with red mud disposal and subsequent rehabilitation of the disposal sites. Whilst practicable bulk uses for the large amounts of slags that are produced have been found, the uses for red mud are limited and only ...

  • Study of Leaching and Adsorption of Heavy Metals by the Activated Carbon Derived From Sewage Sludges

    Six types of activated carbons were produced from digested sewage sludge by different manufacture routes and characterized by the surface area and porosity analysis. They were then subjected to the leaching tests and adsorption tests for heavy metals by batch technique. The results show that all these activated carbons had a notable surface area and porosity. For most sludge-derived activated ...


  • New play on organoclay

    AquaBlok, Ltd., a manufacturer of innovative clay-based composite materials, has announced the introduction of a new organoclay product that provides for ease of delivery and improved performance of this well known remedial material technology. What the company calls 'AquaBlok+ORGANOCLAY' will preferentially adsorb and sequester a wide range of hydrocarbon and petroleum based contaminants. It can ...

  • Treatment and reuse of wastewater in pesticide 2,4-D production

    Waste-water from the production of pesticide 2,4-D often contains high concentrations of 2,4-DCP and 2,6-D as the primary pollutants. Treatment of waste-water collected from a 2,4-D manufacturer was carried out using a technology combining acidification with hyper-crosslinked resin NDA-150 adsorption process. The overall process recovered 5.4 kg of 2,4-DCP and 0.6 kg of 2,6-D per cubic metre of ...
