  • Performance of airlift MBR for on-site treatment of slaughterhouse wastewater in urban areas of Vietnam

    In many cities in Vietnam, wastewater generated in slaughterhouses is normally discharged directly into surface waters without treatment. Management of slaughterhouse wastewater (SHWW) is difficult due to the lack of infrastructure for conveyance to centralized facilities. On-site treatment presents one cost-effective way of managing SHWW compared to mass improvement of infrastructure. This ...

  • Optimisation of bioflocculant production by a biofilm forming microorganism from poultry slaughterhouse wastewater for use in poultry wastewater treatment

    Poultry slaughterhouse wastewater contains nutrients that are sufficient for microbial growth; moreover, the wastewater has microorganisms which can be harnessed to perform specific functions. Additionally, these microorganisms can grow either in planktonic (free floating) mode or sessile (attached) mode. This study focused on the optimisation of bioflocculant production by quantifying ...

  • The potential of ultrasonic membrane anaerobic systems in treating slaughterhouse wastewater

    Direct discharge of slaughterhouse wastewater causes serious environmental pollution due to its high chemical oxygen demand (COD), total suspended solids (TSS) and biochemical oxygen demand. In this study, an ultrasonic-assisted membrane anaerobic system was used as a novel method for treating slaughterhouse wastewater. Six steady states were achieved, using concentrations of 7,800–13,620 mg/l ...

  • Imposex and novel mechanisms of reproductive failure induced by tributyltin (TBT) in the freshwater snail Pomacea canaliculata

    The effects of TBT on mortality and reproduction were studied in this invasive snail. The nominal fifty percent lethal concentration (LC50) was 9 µg TBT/L, after 28 days. The nominal ‘no observed effect on lethality concentration’ (NOECL) was 6 µg TBT/L after the same period. Male‐female couples and females that had been group‐mated but were isolated from males during the experiment (isolated ...
