  • Looking Beyond Chemical Water Treatment Case Study

    When you think of an environmentally friendly company, a steel processing plant does not typically come to mind. However, Stripco Inc. of Mishawaka, IN, a manufacturer of production-ready, cold-rolled steel coils, is the exception. In August of 1995, Stripco made a wise decision that also proved to be cost-effective and environmentally- friendly when they installed a Superior Environmentalist ...

  • From Waste in Anodising Plant to New Chemical Product in Sewage Treatment Plants

    Aluminium containing caustic soda used as a pickling agent in the pre-treatment of aluminium before anodising and aluminium containing sulphuric acids used as electrolytes for the formation of oxide layers in anodising plants can be utilised in municipal sewage treatment plants to reduce phosphates and improve precipitation. From the anodiser's point of view, these products are spent once they ...


  • Sustainable wastewater treatment chemicals in a dairy

    Problem/Definition Atana Ltd has been tasked in reducing sludge generation produced at the sites effluent plant by introducing a new chemical regime.

  • Chemical monitoring strategy for the assessment of advanced water treatment plant performance

    A pilot-scale plant was employed to validate the performance of a proposed full-scale advanced water treatment plant (AWTP) in Sydney, Australia. The primary aim of this study was to develop a chemical monitoring program that can demonstrate proper plant operation resulting in the removal of priority chemical constituents in the product water. The feed water quality to the pilot plant was ...

  • AFM water treatment for biodiversity

    The discharge of List 1 bio-accumulated chemicals into the marine environment is one of the most serious forms of pollution that we inflict on our environment. The marine enviroment is responsible for the production of most of our oxygen and reduction of carbon dioxide. Tropical rainforrests and terestial plants are also extremely important in dictating our local climate, however they ...

  • Water treatment technology for produced water

    Large amounts of produced water are generated during oil and gas production. Produced water, as it is known in the oil industry, is briny fluid trapped in the rock of oil reservoirs. The objective of this study was to test produced waters from a Montana USA oilfield using a mobile station to design a plant to cost efficiently treat the produced water for agricultural irrigation. We used combined ...

  • Nanofiltration As a Post-Treatment at a Conventional Water Treatment Plant

    Introduction The Clifton Water District (Colorado) covers roughly 20 square miles stretching east of Grand Junction to Palisade, and extending south from I-70 to the Colorado River. The District has approximately 7,400 service connections serving a population of 30,000. Utilizing the Colorado River as its primary source, the District's Charles A. Strain Water Treatment Plant has a capacity of 12 ...


  • Anaerobic-aerobic treatment of toxic effluents from the production of fine chemicals using biomass immobilised on LEVAPOR carrier

    1. The problem The effluents of such production sites are polluted both, with Biologically acting active substances and their byproducts, respectively with Solvents (methanol, aromates, etc.). Waste water flow ~ 200 to 300 m³/day COD ~ 15,0 to 20,0 g/L, NH4N ~ 0,4 g/L to 0,6 g/L 2. The solution Lab scale tests ...

  • 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 ...

  • The application of potassium manganate in water treatment

    This paper explores the feasibility of using potassium manganate (K2MnO4) in water treatment. Manganate (Mn(VI)), like ferrate (Fe(VI)), can act as both an oxidant and a coagulant/adsorbent arising from the formation of insoluble manganese dioxide (Mn(IV)) from the chemical reduction of MnO42−. In this paper the basic properties of K2MnO4 are described, including the standard electrode potential ...
