Alum treatment of runoff has been used as a stormwater retrofit option for the past 20 years. This technology has evolved from the initial demonstration research projects to a viable retrofit option for urban areas. A considerable amount of data has now been collected on the water quality and ecological impacts of alum treatment systems. Alum treatment of stormwater consistently provides remova...

Pigs (25-45 kg) were fed on either cereal or semi-purified basal diets supplemented with either high or low levels of sugar-beet pulp or wood cellulose (Solka-floc). The apparent digestibility and retention of N and apparent digestibility and metabolizability of energy (GE) and the apparent digestibility of non-starch polysaccharides (NSP) and their constituent monomers were measured during wee...

We present a fast local clustering service, FLOC, that produces nonoverlapping and approximately equal-sized clusters. The clustering is such that all nodes within unit distance of a clusterhead belongs to its cluster, and no node m units away from the clusterhead may belong to its cluster. By asserting m ≥ 2 FLOC achieves locality: effects of cluster formation and faults/changes at any part of...

OBJECTIVE To determine the health status of people in Australian immigration detention centres and the effect of time in, and reason for, detention. DESIGN, SETTING AND SUBJECTS An analysis of the health records of 720 of the 7375 people in detention in the financial year 1 July 2005-30 June 2006, with oversampling of those detained for > 3 months. MAIN OUTCOME MEASURES Health encounters an...

In order to observe the impact of different water compositions on sludge dewaterability, assessments of floc sizes using a particle size analyzer and of sludge dewaterability based on the capillary suction time (CST) test were carried out. Synthetic raw water had small floc sizes, and synthetic domestic wastewater had both larger median floc sizes and a better correlation between sludge dewater...
