  • Using Nanofiltration in Beverage Production

    The following article is based on a paper presented in August, 1990 at the 21st Annual Meeting of the Fine Particle Society in San Diego. Soft drink manufacturers, not to mention manufacturers of other beverage products, have always had a keen interest in the water that goes into their products. After all, it is the water that typically makes up 80%-90% of the product. In the past the water has ...

  • Treatment of landfill leachate by hybrid precipitation/microfiltration/nanofiltration process

    This paper describes a promising method to treat stabilized landfill leachate. Such method consists of a combination of chemical precipitation processes, a cost-effective technique with high potential to remove contaminants with foulant nature, microfiltration aimed at removing the produced precipitate and nanofiltration (NF) for final polishing. This study was carried out on a bench unit ...

  • Treating Industrial Water with Membrane Technology

    A variety of industries are finding that it makes sense to reevaluate the way they treat industrial process water, both to improve the quality of their products and increase the efficiency of their processes. Purification systems utilizing crossflow membrane filtration, such as reverse osmosis (RO), nanofiltration (NF) or ultrafiltration (UF) can be a good alternative to traditional filtration ...


  • Analyzing the spatial and temporal characteristics of membrane fouling

    Fouling characteristics of crossflow flat-sheet membranes for two Nanofiltration (NF), one Ultrafiltration (UF), and one Microfiltration (MF) membranes were analyzed using 12.5 parts per million (mg/L) FeCl3 solution and 350 mg/L copper nanofluid. FeCl3 solution represents dissolved contaminant whereas copper nanofluid simulates particulate contaminant. The spatial and temporal fouling ...
