Detection of salmonella in composted wastewater sludge: a report on a research project carried out for the Water Authority of Western Australia [PDF]
, 1995 It is likely that Australian sludge management guidelines will require monitoring of composted wastewater sludge for the presence of salmonellae. However, methods to perform this monitoring are not well established and it appears that methods used in the

Decolorization of Disperse Dyes in Textile Polyester Recycling Using Activated Carbon
Chemie Ingenieur Technik, EarlyView.Decolorization of disperse dyes from disodium terephthalate solutions is examined using two activated carbons with varying pore structures and surface properties. The potential impact of pore size distribution and surface charge on the adsorption process is assessed to support optimized adsorbent selection.

CONVERSION OF SLUDGE TO OIL: A NOVEL APPROACH TO SLUDGE MANAGEMENT
Water Science and Technology, 1988 Experiments at the Wastewater Technology Centre have shown that low temperature conversion of sludge to oil represents a promising alternative to sludge incineration. A 1kg/h bench-scale reactor produced oil yields ranging from a low of 13% for an anaerobically digested sludge to a high of 46% for a mixed raw sludge.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C
