Full Description

This slide presentation investigates the use of both nanoporousmagnesium aluminate spinel andaluminium oxide coated filter media forfiltration of microbial contaminates duringdrinking water filtration. Topics outlined under Experimental Setup include Aluminium Oxide Preparation and Magnesium Aluminium SpinelPreparation. Conclusions were thatwith a greater isoelectric point thanaluminium oxide, magnesium aluminatespinel will have a greater positive chargeat normal drinking water pH, and thereforeit will have greater electrostatic attractionto negatively charged water contaminates. Includes table, figure.
