Performance results have demonstrated the benefits of the alum sludge cakes in a lab-scale system in enhancing phosphorus (P) removal from an animal farm wastewater. Although P and organic matter were concurrently removed in the system, there was a probable “one off” release of organics from the system, and this coincided with an increase in inlet P concentration from 39.2 mg-P/l to 163.0 mg-P/l. A conceptual model was then proposed to explain and discuss this.||Funding Details:||Other funder||Type of material:||Journal Article||Publisher:||DesTech Publications||Journal:||Journal of Residuals Science & Technology||Volume:||4||Issue:||3||Start page:||147||End page:||152||Keywords:||Adsorption; Dewatered alum sludge; Phosphorus; Vertical flow constructed wetland; Waterworks sludge; wastewater treatment; Organic matter||Subject LCSH:||Water treatment plant residuals
