  • Forward osmosis for the treatment of reverse osmosis concentrate from water reclamation: process performance and fouling control

    While high quality water reuse based on dual membrane filtration (membrane filtration or ultrafiltration, followed by reverse osmosis) is expected to be progressively applied, treatment and sustainable management of the produced reverse osmosis concentrate (ROC) are still important issues. Forward osmosis (FO) is a promising technology for maximising water recovery and further dewatering ROC so ...

  • The significance of interactions between organic compounds on low pressure membrane fouling

    Fouling of hollow fibre microfiltration and ultrafiltration membranes by solutions of pure organic compounds and mixtures of these compounds was studied with a backwashable membrane filtration apparatus. Small molecular weight compounds resulted in little fouling, while their polymeric analogues resulted in more severe fouling. Neutrally charged dextran resulted in minor, irreversible fouling, ...

  • Mitigating Environmental Impact Of Gold Mine Wastewater Through Ozone Oxidation And Aquifer Re-injection

    US Environment Protection Agency (USEPA) regulations require mining operations to remediate their waste streams prior to environmental discharge. Wastewater streams from gold mine operations can be particularly toxic due to the potential for cyanide contamination and the concentration of metals contained in the wastewater effluent. This paper reviews the challenges and success of installing and ...

  • Membrane filtration of agro-industrial wastewaters and isolation of organic compounds with high added values

    The aim of the current study was the exploitation of agro-industrial wastes or by-products such as olive mill wastewater (OMW) and defective wines. A cost-effective system for their maximum exploitation is suggested, using a combined process of membrane filtration and other physicochemical processes. Wastewaters are first treated in a membrane system (prefiltration, ultrafiltration, ...
