• Fully enclosed system The remoteness of the iron ore mines in Western Australia means the workers facili es need to be supplied with their own infrastructure including sewage treatment plants. The solid waste produced from these plants, otherwise known as biosolids, needs to be disposed of in an appropriate manner.

1. Introduction. With the continuous development of modern industry, the increasing amount of wastewater inevitably adds to the burden of sludge treatment (Ling et al., 2022).For example, the amount of sludge produced by urban sewage treatment plants in China increased from 13.784 million tons in 2019 to 14.535 million tons in 2020 …

Overview of sludge thickening and dewatering. Thickening and dewatering processes both provide a concentrated, consolidated product − retaining most of the solids from the original sludge – along with a diluted stream which is predominantly water. For both process types the dilute stream is usually directed back to the inlet of the …

Sludge conditioning is a crucial step in sludge dewatering aimed at minimizing excessive sludge production. The Fenton process, which harnesses oxidative radicals to dismantle extracellular polymeric substances (EPS) and microorganisms, has been unequivocally proven to enhance sludge dewaterability. However, the widespread …

The tailings slurry samples were taken from the Choghart iron ore processing plant in Bafq, Yazd, Iran. Dewatering of the slurry (containing less than 20% iron) in the plant is performed in thickeners by adding commercial polyacrylamide flocculants. The slurry had a turbidity of higher than 10000 NTU and a pH of about 8.
