Constructed wetlands using aluminium-based drinking water treatment sludge as P-removing substrate : should aluminium release be a concern?

Babatunde, A.O. ; Kumar, J.L.G. ; Zhao, Y.Q. (RSC Publishing, 2011-06)

This study investigated an important issue of aluminium (Al) release in a novel reuse of Al-based water treatment sludge (Al-WTS) in constructed wetland system (CWs) as alternative substrate for wastewater treatment. Al-WTS ...
Dewatered alum sludge : a potential adsorbent for phosphorus removal

Yang, Y. ; Tomlinson, D. ; Kennedy, S. ; Zhao, Y.Q. (IWA Publishing, 2006-06)

Alum sludge refers to the by-product from the processing of drinking water in Water Treatment Works. In this study, groups of batch experiments were designed to identify the characteristics of dewatered alum sludge for ...
Fluoride removal from drinking water by adsorption using bone char as a biosorbent

Ma, W. ; Ya, F. ; Wang, R. ; Zhao, Y.Q. (Inderscience, 2008-04)

As a biomass material, bone char was investigated for the feasibility to be used as a cost-effective biosorbent for fluoride removal from drinking water in groundwater environment. Based on the batch tests with natural ...
An innovative solution for managing waterworks sludge : developing an alum sludge-based multi-stage constructed wetland system for wastewater treatment

Zhao, Y.Q. ; Babatunde, A.O. ; Zhao, X.H. (ASTM, 2009-06)

Waterworks sludge continues to be an inescapable by-product of the potable water treatment process. Accordingly, final disposal of the sludge remains one of the most significant pressing problems for the potable water ...
Pilot field-scale demonstration of a novel alum sludge-based constructed wetland system for enhanced wastewater treatment

Zhao, Y.Q. ; Babatunde, A.O. ; Hu, Y.S. ; Kumar, J.L.G. ; Zhao, X.H. (Elsevier, 2011-01)

In this study, beneficial reuse of the alum-contained drinking water treatment sludge is extended into developing a novel constructed wetland system (CWs) using the alum sludge as main substrate. The study reports on the ...
Removal of glyphosate from aqueous environment by adsorption using water industrial residual

Hu, Y.S. ; Zhao, Y.Q. ; Sorohan, B. (Elsevier, 2011-04)

This study investigated the glyphosate adsorption by water treatment residual (termed as alum sludge) in dewatered form (DAS) and liquid form (LAS). Batch adsorption tests were carried out with DAS at different pH, particle ...
Reuse of aluminium-based water treatment sludge to immobilize a wide range of phosphorus contamination : equilibrium study with different isotherm models

Zhao, Y.Q. ; Razali, Melanie ; Babatunde, A.O. ; Yang, Y. ; Bruen, Michael (Taylor & Francis, 2007-10)

The adsorption equilibrium of a wide range of phosphorus species by an aluminium-based water treatment sludge (Al-WTS) was examined in this study. Four kinds of adsorption-isotherm models, namely Langmuir, Freundlich, ...
