  • Vibratory Finishing

    The treatibility required no pH adjustment from the initial 7.5 pH. The treatment required 0.15 grams of Floccin-J in a 100 ml sample. The dosage equates to a treatment of 12 lbs/1,000 gallons. Based on $1.25/lb for Floccin-J, the treatment costs will be about $15/1,000 gallons = 1.5 cents/gallons. Based on the water clarity, the facility might be able to reuse the water and reduce their fresh ...

  • Quantification and molecular characterisation of human sapoviruses in water sources impacted by highly polluted discharged wastewater in South Africa

    Sapoviruses (SaVs) were detected and quantified in 8/10 water samples collected from wastewater treatment works (WWTWs) and water sources impacted by these WWTWs in Limpopo Province, South Africa. The median SaV concentration was 2.45 × 106 copies/L and SaV genotypes I.2 and IV were characterised. This study provides new data on the high concentrations of clinically relevant SaVs in rivers and ...

  • Wickford junction

    Wickford Junction sits atop a gravel aquifer recharge zone. A Walden SBR system was chosen to treat the wastewater flow from a proposed shopping center in order to remove contaminants prior to discharge to a disposal field. The shopping center was to be built in phases and the developer wanted the flexibility to incrementally add treatment capacity as additional store fronts were added. ...

  • Decolourisation of dye solution using an electrical discharge with TiO2 suspension

    An electrical discharge in water with TiO2 suspension has been applied for the decolourisation of methyl orange as a model of dye. The results showed the decolourisation was successful in the reactor. The increase in the flow rate of gas injection enhanced the decolourisation rate. Oxygen injection had a stronger influence when compared with Ar injection. The suspension of TiO2 improved the ...

  • Effluent polishing at STW`s Ruurlo and Wehl, The Netherlands

    At the end of 1997 STW's Ruurlo and Wehl, from Waterboard Rijn en IJssel (WRIJ), were completely renewed and expanded with an effluent polishing using Astrasand continuous filtration. This is the first time that a post treatment filtration has been applied to municipal wastewater in the Netherlands. By using this method it is possible to produce a high quality effluent, which can be discharged ...
