Alum sludge-based constructed wetland system for enhanced removal of P and OM from wastewater : concept, design and performance analysis

Babatunde, A.O. ; Zhao, Y.Q. ; Zhao, X.H. (Elsevier, 2010-08)

The concept, design and performance analysis of a four-stage novel constructed wetland system (CWs) capable of enhanced and simultaneous removal of phosphorus (P) and organic matter (OM) from wastewaters is described. Alum ...
Decolouration of H2SO4 leachate from phosphorus-saturated alum sludge using H2O2 and advanced oxidation processes in phosphorus recovery strategy

Zhao, X.H. ; Zhao, Y.Q. (Taylor & Francis, 2009-11)

As a part of attempt for phosphorus (P) recovery from P-saturated alum sludge, which was used as a low-cost P-adsorbent in treatment reed bed for wastewater treatment, decolouration of H2SO4 leachate obtained from previous ...
Development of alum sludge-based constructed wetland : an innovative and cost-effective system for wastewater treatment

Zhao, Y.Q. ; Babatunde, A.O. ; Zhao, X.H. ; Li, W.C. (Taylor & Francis, 2009-05)

This paper describes (in a summarised manner) a research attempt to integrate the dewatered alum sludge, a residual by-product of drinking water treatment process, into a constructed wetland (CW) system for the purpose of ...
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 ...
Investigation of phosphorus desorption from P-saturated alum sludge used as a substrate in constructed wetland

Zhao, X.H. ; Zhao, Y.Q. (Elsevier, 2009-04-07)

Phosphorus (P) desorption from P-saturated alum sludge, which was used as main substrate in a novel constructed wetland for wastewater treatment, was studied. Groups of batch experiments were designed and conducted to ...
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 ...
A two-prong approach of beneficial reuse of alum sludge in engineered wetland : first experience from Ireland

Zhao, Y.Q. ; Babatunde, A.O. ; Hu, Y.S. ; Kumar, J.L.G. ; Zhao, X.H. (Springer, 2010-06)

Effective management of the industrial waste requires a sustainable approach that maximizes its value of reuse/recycle for other industrial demands and the environment needs. This paper aims in exploring the potential of ...
Use of dewatered alum sludge as main substrate in treatment reed bed receiving agricultural wastewater : long-term trial

Zhao, Y.Q. ; Zhao, X.H. ; Babatunde, A.O. (Elsevier, 2009-01)

This study aims to explore a novel application of dewatered alum sludge cakes (DASC) as the main medium in a single model reed bed to treat phosphorus-rich animal farm wastewater under "tidal flow" operation on a long term ...
