Abstract

A packed-bed column was developed to study the performance of Ceiba pentandra (L). Gaertn. (kapok) for oily water filtration using a three-level, two-factor factorial design. This was based on the effects of packing density and flow rates on chemical oxygen demand (COD) and turbidity of the effluent. CODwas significantly affected by the quadratic effects of flowrates. The optimum packing density and flowrate forminimumCODwere predicted at 0.07 g/cm3 and 1.09 L/h,whichwerewithin the range tested. About 99% of CODreductionswere observed at all packing densities and flow rates. Similarly, more than 87% of turbidity reductions were achieved at all packing densities and flow rates. A deep-bed kapok filtration column constructed in this study had been successful in achieving oily water separation under different packing densities and flow rates. The oil and water front movements were shown to be influenced by the affinity of liquid to kapok fibers. Thismay suggest the excellent physicochemical property of Malaysian kapok for oil removal from water.
