(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 ...
-
(Taylor & Francis, 2010-07)The generation of alum sludge from drinking water purification process remains inevitable when aluminium sulphate is used as primary coagulant for raw water coagulation. Sustainable managing such the sludge becomes an ...

(Springer, 2010-08)Concept and purpose Virtually all water treatment facilities worldwide generate an enormous amount of water treatment residual (WTR) solids for which environmentally-friendly end-use options are continually being sought ...
-
(Taylor & Francis, 2010-11)Currently, organic polymers are adopted in alum sludge (aluminium-coagulated drinking water treatment sludge) conditioning. However, there are important concerns regarding the use of these polymers because of the unknown ...

(Elsevier, 2010-12-15)Excess phosphorus (P) in wastewaters promotes eutrophication in receiving waterways. A cost-effective method such as use of novel low-cost adsorbents for its adsorptive removal would significantly reduce such impacts. Using ...

(Taylor & Francis, 2010-09)In this study, dewatered alum sludge cakes were used as substrate in a laboratory scale tidal vertical flow reed bed system treating animal farm wastewater. The “tidal flow” operation was employed to enhance oxygen ...
-
(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 ...
-
(Elsevier, 2011-05)Dewatered alum sludge, a widely generated by-product of drinking water treatment plants using aluminium salts as coagulants was used as main substrate in a pilot on-site constructed wetland system treating agricultural ...
-
(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 ...
-
(Taylor & Francis, 2010-10)This study assessed the potential reuse of an aluminium coagulated drinking–water treatment sludge (Al–DWTS) as a main substrate in constructed wetland to replace soil for the treatment of P-enriched wastewater. The ...
