Abstract

In this study solidification/stabilization SIS of nickel hydroxide sludge using ordinary Portland cement OPC and oil palm ash OPA was carried out. Results indicated the optimum mix design for SIS of nickel hydroxide sludge using both OPC and OPA at B/Sd 1 in terms of cost-effectiveness and treatment efficiency was 15 wt OPA 35 wt OPC and 50 wt sludge. The sufficient DCS and low leached nickel concentrations shown for this mix design indicate the viability of using OPA as substitute of OPC as it can significantly reduce cost normally incurred by usage ofhigh amounts ofOpe. The optimum mix design for this study was also compared with other SIS studies.
