  • Sonocatalytic treatment of baker's yeast effluent

    Baker's yeast effluent is a major source of pollution with a high organic load and dark colour. It can be treated by using advanced oxidation processes (AOPs). AOPs, such as ultrasonic irradiation, are ambient temperature processes involving the generation of free radicals. We have investigated sonocatalytic treatment of baker's yeast effluent by using ultrasound. TiO2–ZnO composites were used ...

  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • Anaerobic effluent treatment at a chemical industrial complex

    In order to test the feasibility of anaerobic treatment of an effluent from a chemical factory producing intermediates for synthetic fibres, test work with a 45 l UASB pilot plant was conducted. After conducting a successful pilot study a full-scale anaerobic effluent treatment plant including a 400 m3 combined buffer/pre-acidification tank and a 990 m3 Biopaq®-UASB reactor was constructed. The ...

  • Treatment for woolscouring effluent through bioacidification by acidithiobacillus thiooxidans

    In this study, a promising process called bioacidification was used to remove organic pollutant from Woolscouring Effluent (WSE) by emulsion destabilisation. Chemostat experiments of bioacidification treatment inoculated with Acidithiobacillus thiooxidans were operated at high wastewater recycle ratios to achieve shorter Hydraulic Retention Time (HRT). Results exhibited high COD removal ...

  • Soil aquifer treatment using advanced primary effluent

    Soil aquifer treatment (SAT) using primary effluent (PE) is an attractive option for wastewater treatment and reuse in many developing countries with no or minimal wastewater treatment. One of the main limitations of SAT of PE is rapid clogging of the infiltration basin due to high suspended solid concentrations. Some pre-treatment of PE before infiltration is likely to reduce this limitation, ...

  • Final effluent monitors protect wastewater treatment efficiency

    Southern Water operates 370 wastewater treatment plants (WWTP), many of which are unmanned for most of the time and most have numeric environmental permits, so a network of online monitors has been established to improve treatment and protect discharge compliance. This has involved the installation of final effluent monitors at over 300 sites in a programme that has lasted for more than ten ...


  • Zero Effluent by Application of Biological Treatment at High Temperature

    For the production of high quality corrugated medium and test liner it has been shown since 1995 at a new large size mill in Germany, that no or practically no effluent discharge is necessary when the process water is treated in an anaerobic/aerobic conventional treatment plant, which is followed by sand filtration. In this paper, three different projects are described which show, that the number ...

  • Optimised treatment of Palm Oil Mill Effluent

    In this paper, we study experimentally the problem of separating oil from the oil?water emulsion that emulates Palm Oil Mills Effluent (POME). The investigations are focused on the effects of hydrochloric acid (HCl) and treatment conditions, e.g., operating temperature and magnetic stirring, on the separation process. The experiment results reveal that a higher flotation rate of oil is achieved ...

  • Pilot-scale studies on the treatment of tannery effluents by electroflotation

    A pilot-scale electroflotation system with a treatment capacity of 0.8 m³ per hour has been designed and built. The system is equipped with a conditioning tank, a rectifier, flow meters, an energy meter and pumps. Iron, aluminium and titanium coated with oxides of tantalum, ruthenium and iridium were used as electrodes. The system was installed within the premises of the Common Effluent Treatment ...

  • Treatment of hospital wastewater effluent by nanofiltration and reverse osmosis

    Considerable concern exists regarding the appearance and effects of trace and ultra trace pollutants in the aquatic environment. In this context, it is necessary to identify relevant hot spot wastewater – such as hospital wastewater – and to implement specific wastewater treatment solutions. Membrane bioreactor (MBR) technology seems to be a suitable pre-treatment approach for the subsequent ...

  • Treatment of Water-Wash Paintbooth Effluents in the Automotive Industry

    During the coating process of car bodies in water-wash spray booth, around 40% of the sprayed paint does not reach the support; these paint particles sprayed into the air are called “overspray”. By using a dawn-draft positive air pressure coming from the ceiling of the cabin, the polluted air is forced vertically downward toward a grating on the floor under which a constant stream of water is ...

  • Sewage/effluent treatment by growth of diatom algae

    A new process to treat sewage/e²uents, by using Nualgi, a patented product that aids the growth of diatom algae in the waste water is described. The growing diatom algae absorb nutrients and carbon dioxide from the water and produce oxygen by photosynthesis at micro plant level. The oxygen released during photosynthesis helps aerobic bacteria in breaking down the organics and converting the ...

  • Improved Effluent Treatment Systems: Australian National Railways

      An environmental audit of Australian National Railways' facilities in various States identified a serious problem with the performance of wastewater and effluent treatment systems at several sites. Implementation of cleaner production measures has resulted in improved environmental performance and cleaning efficiencies at reduced operational cost. Background In late 1995, ...


  • Use of ozone in the treatment of cyanide containing effluents

    The treatment of effluents of the gold and silver cyanidation process is one of the main problems that the precious metals industry faces. These effluents contain variable quantities of free cyanide, weak complexed cyanide, strong complexed cyanide and thiocyanate. Different methods are used for the removal of cyanide but most of the times the consumption of reagents raises the operation cost to ...
