The fear that contaminated leachate could escape from the Trail Road Municipal Landfill Site, and the need for a cost-effective on-site treatment alternative, has led to an evaluation of the options for treating the leachate. One treatment option being examined is the use of low-pressure reverse osmosis (RO), which is becoming increasingly attractive with the development of new technology. The purpose of this study is to evaluate the technical feasibility of this treatment process for synthetic and real landfill leachate. Membrane 'coupon' experiments were conducted to study three types of low-pressure membranes (supplied by Hydranautics, Fluid Systems, and Saehan Industries), to determine the membrane with the highest permeate flux and rejection capabilities, to conduct statistical analysis on the testing apparatus and to test how the selected membrane was able to cope with different concentrations of synthetic leachate at different operating pressures. Membrane 'coupon' experiments were conducted on the Hydranautics' membrane with actual Trail Road leachate to determine the effect of leachate concentration and operating pressure on the product flux and on the TOC, NH3, and the Cl-- removal efficiencies. Tests on Trail Road leachate samples were conducted with a lab-scale Hydranautics' spiral-wound membrane at operating pressures of 40, 50, and 60 psi (276, 345, and 413 kN/m2).
