Zero discharge-orientated water management strategies for coal conversion facilities indicate that process wastewater is a prime source of cooling tower make-up water, and that a demineralisation technology will be used for process wastewater to achieve the quality criteria necessary for operating cooling towers at high cycles of concentration. Reverse osmosis was considered to be the most appropriate of available demineralisation processes, and laboratory-scale RO experiments were carried out with a phenolic coal gasification wastewater which had been processed through a series of pretreatment steps including activated carbon adsorption. Tests using a polyamide membrane gave somewhat higher product water quality, which a cellulose triacetate membrane provided greater flux rates.
