Upgrading waste activated sludge into valuable biosolids via an integrated biochemical approach
Water Research XSludge management is a significant challenge for water utilities worldwide. High costs are largely driven by poor digestibility and dewaterability, while elevated concentrations of pathogens and toxic metals limit the safe and beneficial reuse of sludge.

Influence of water treatment residuals on dewaterability of wastewater biosolids
Water Science and Technology, 2013 Co-dewatering of water treatment residuals (WTR) and wastewater biosolids can potentially benefit municipalities by reducing processing equipment and costs. This study investigated dewaterability (using capillary suction time, CST) of combined alum residuals (Al-WTR) and anaerobically digested biosolids at various blending ratios (BR), defined as the ...
