  • 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 ...

  • 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 ...

  • Incorporating sustainability in textile effluent treatment facilities

    Sustainable development encompasses environmental, social and economic considerations. As such, the stakeholders include industry, government, individuals and communities. When designing or operating an industrial plant, it is insufficient to consider only the economic viability of the facility. This paper examines the background to current sustainability awareness and presents a case study that ...

  • Airport deicing effluent treatment and regulatory guidelines

    Airport and airplane deicing is employed with the use of brines, salts, alcohols or glycols to remove and prevent or delay the formation of snow and ice.  In the United States (US), the Federal Aviation Administration requires airlines that operate during icy conditions to perform deicing and anti-icing of aircraft and airfield pavement (USEPA 2011a).  These deicing operations use large ...

  • A hybrid flotation: microfiltration cell for effluent treatment

    The investigated hybrid cell combines the advantages of both flotation and membrane filtration, while overcoming their limitations and having as outcome clean water from wastewater. The specific objective of the current paper was to apply the process for the efficient separation of effluents containing toxic metals (zinc cations and chromate anions). The main examined parameters were the sorbent ...

  • 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 ...

  • 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 ...

  • 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, ...
