Characteristics and mechanisms of phosphate adsorption on dewatered alum sludge

Yang, Y. ; Zhao, Y.Q. ; Babatunde, A.O. ; Wang, L. ; Ren, Y.X. ; Han, Y. (Elsevier, 2006-09)

The adsorption characteristics of phosphate adsorption on the dewatered alum sludge were identified as a function of pH and ion strengths in solution. In addition, adsorption mechanisms were investigated by conducting batch ...
Co-conditioning of the anaerobic digested sludge of a municipal wastewater treatment plant with alum sludge : benefit of phosphorus reduction in reject water

Yang, Y. ; Zhao, Y.Q. ; Babatunde, A.O. ; Kearney, P. (Water Environment Federation, 2007-12)

In this study, alum sludge was introduced into co-conditioning and dewatering with an anaerobic digested activated sludge to examine the role of the alum sludge in improving the dewaterbility of the mixed sludge and also ...
From "fills" to filter : insights into the reuse of dewatered alum sludge as a filter media in a constructed wetland

Babatunde, A.O. ; Zhao, Y.Q. ; Yang, Y. ; Kearney, P. (DesTech Publications, 2007-07)

Dewatered alum sludge, a by-product of drinking water treatment plants, hitherto consigned to landfills was used to develop a novel bio-filter in form of a constructed wetland. Performance results have demonstrated the ...
Influence of ageing on the structure and phosphate adsorption capacity of dewatered alum sludge

Yang, Y. ; Zhao, Y.Q. ; Kearney, P. (Elsevier, 2008-12-15)

In line with the increasing studies on the beneficial reuse of alum sludge from a “waste” into useful raw material, this paper reports an in-depth investigation of the effects of ageing time on the structure and the phosphate ...
