  • Membrane Selection and Optimal Ammonium Nitrate Chemistry for Reverse Osmosis Treatment of Explosive Wastewater

    A process for manufacturing explosives produces an ammonium nitrate-laden wastewater, which can be successfully treated with reverse osmosis (RD). Key to RD use is balancing the competing waste solution chemistry requirements of the two target solutes, to enhance the performance of the particular RD membrane chosen. While the EPA requires only the reduction of the N03 and NH4+ discharge levels ...

  • Chemical wastewater treatment applying a membrane bioreactor (MBR)

    IntroductionAt the current time Membrane Bioreactors (MBR) are the primary focus of wastewater treatment technologies. MBR is a combination of biological activated sludge process for the removal of nutrients and a membrane filtration for separation of biomass and treated water. In industrial wastewater treatment MBRs have proven to be a particularly reliable technique [Cornel et al., 2006]. The ...

  • Oily wastewater treatment using membrane bioreactor

    A novel implementation of a membrane bioreactor (MBR) has been studied in this paper. It is utilised as combination of rotating biological contractor (RBC) and an external membrane for oily wastewater treatment. The performance of MBR was compared with the standalone RBC. The RBC used in this investigation is the same one combined with the membrane to form the MBR. Wastewater biodegradability has ...

  • Optimization of cyanide extraction from wastewater using emulsion liquid membrane system by response surface methodology

    To solve the disposal problem of cyanide wastewater, removal of cyanide from wastewater using a water-in-oil emulsion type of emulsion liquid membrane (ELM) was studied in this work. Specifically, the effects of surfactant Span-80, carrier trioctylamine (TOA), stripping agent NaOH solution and the emulsion-to-external-phase-volume ratio on removal of cyanide were investigated. Removal of total ...
