Behaviour Of Waterworks Alum Sludge For Phosphate Removal

Research output: Contribution to conferencePaper

Abstract

In the agricultural sector, fertilizer and animal waste are main pollutants to water
course. Excessive phosphorus in water bodies may increase the growth of algae and aquatic plant
in a pond which leads to eutrophication phenomena. Disposal of alum sludge in landfills can lead
to contaminant issues thus, researchers are searching for ways to reduce excessive disposal of
waste including alum sludge in landfills. This study provides available options to reuse alum
sludge. The continuous column tests were conducted with different initial pH and contact initial
phosphate concentrations. The Scanning Electron Microscope test (SEM) indicates that rough
alum sludge surface possibility to adsorb phosphate molecules. This result shows that phosphate
removal rate is higher in acidic condition but lower in alkaline condition. In wastewater
treatment industries, changing wastewater to pH 4 needs a large amount of chemical additive and
suggests that the pH 7 ±0.5 is more suitable in wastewater applications. In the agricultural sector, fertilizer and animal waste are main pollutants to water
