Effect of proteins, polysaccharides, and particle sizes on sludge dewaterability
Journal of Environmental Sciences, 2009Four batch experiments of hydrolysis and acidification were carried out to investigate the distributions of proteins (PN) and polysaccharides (PS) in the sludge, the PN/PS ratio, the particle sizes, and their relationship with sludge dewaterability (as determined by capillary suction time, CST).

Effects of explosive explosion shockwave pretreatment on sludge dewaterability
Bioresource Technology, 2012The potential benefits and mechanism of explosive explosion shockwave pretreatment on sludge dewatering treatments were investigated in this study. Water content of sludge cake after centrifugation was used to evaluate sludge dewaterability. Particle size, viscosity, turbidity, and micrograph were determined to explain the observed changes in the ...

Dewaterability characteristics of sludge conditioned with surfactants pretreatment by electrolysis
Bioresource Technology, 2011The potential benefits of electrolysis-conditioned sludge dewaterability treatments with surfactants were investigated in this study. Capillary suction time (CST) and specific resistance of filtration (SRF) were used to evaluate the sludge dewaterability.

Ion exchange and dewaterability of clay sludges
International Journal of Mineral Processing, 1980Abstract Two clay gel systems, a sample of settled oil sands clay tailings and a montmorillonite gel, were effectively dewatered by conversion to calcium forms by ion exchange, followed by freezing and thawing in the case of the montmorillonite gel and by either centrifugation or freezing and thawing in the case of the oil sands slime.

Struvite formation for enhanced dewaterability of digested wastewater sludge
Environmental Technology, 2013One of the main advantages of controlled struvite formation in digested sludge is an improvement in dewaterability of the digested sludge, which eventually leads to lower volumes of dewatered sludge that need to be transported. The effects of the control parameters for struvite formation, magnesium concentration and pH, on digested sludge ...
