  • Wastewater Recovery Using Reverse Osmosis

    INTRODUCTION If one were to select a single word describing the most important factor when applying membrane technology to a wastewater application, it would be chemistry. That is not to say that other factors are not important; certainly fluid dynamics and other physical science factors play a major role as well. But it is the chemistry that is so important to success. And it is the ...

  • Evaluating impact of fouling on reverse osmosis membranes performance

    Abstract Membrane fouling is commonly defined as an undesirable formation of deposits on mem- brane surfaces and it is considered a major problem in most brackish, seawater, and waste water reclamation applications. Depending on nature of the scale and foulant, fouling pro- cesses will lead to decreased membrane fluxes, increased pressures needs, and/or increased permeate conductivity. ...

  • Ultrafiltration and Reverse Osmosis for Landfill Leachate Treatment

    Lanchester Landfill serves Eastern Lancaster County and Western Chester County in PA for disposal of household and construction waste. The facility produces around 10,000 gals per day of leachate. The Problem The facility ran a single basin sequential batch reactor (SBR) and a filter press to dewater the solids for many years, but found that they first, could not sustain a ...
