The removal of cadmium (II), onto agricultural waste biomass carya shell (CS) over a wide range of reaction conditions was studied from aqueous solution. These conditions including the effect of solution pH, initial concentration, contact time on sorption efficiency. The cadmium (II) adsorption was favored with maximum adsorption at pH 7.0. The uptake amount of cadmium (II) onto CS was increased with...
This paper studied the effect of microbial species grow speed(MPGS), soluble microbial populations(SMPs) on the excess sludge production in the oxic-settling-anoxic process (OSA process), a modification of conventional activated sludge process by inserting a sludge holding tank in a sludge return line. The OSA process may provide a cost-effective way to reduce excess sludge production in activated...
