N2 - This paper aims to investigate the implementation of membrane processes to recover potable water for reuse from wastewater from a soluble coffee manufacturing plant. An initial screening study was conducted to evaluate flux performance and contaminant rejection for a range of membranes, including microfiltration, ultrafiltration, nanofiltration, and reverse osmosis membranes. Major contaminants considered were chemical oxygen demand (COD), turbidity, and conductivity. All membranes provided similar flux values after 60 minutes of processing. The nanofiltration and reverse osmosis membranes provided excellent contaminant rejection at over 98% for COD and turbidity for both membranes. Conductivity rejection was 51.9% and 98.5% for nanofiltration and reverse osmosis membranes, respectively. Preliminary results of dynamic filtration, by vibration, show increases of steady state flux by a factor of 4 and 1.7 for nanofiltration and reverse osmosis membranes respectively.
