Enhanced Electro-Dewatering of Sludge Through Inorganic Coagulant Pre-Conditioning

Separations
Sludge electro-dewatering technology is an attractive dewatering technology, but its application is limited by high energy consumption and filter cloth clogging caused by the dissolution of extracellular polymeric substances (EPSs). Thus, the addition of

Waste activated sludge high‐rate treatment of septage: Biodegradability studies and contact phase trials towards a cleaner environment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The waste activated sludge high‐rate (WASHR) process, developed in our previous study, is used for septic wastewater treatment. This high‐rate contact stabilization pre‐treatment uses typical waste streams found in wastewater treatment plants to reduce a portion of the loadings on the main treatment trains.

Effects of acid-heat combined treatment on sludge dewatering performance at low temperature [PDF]

E3S Web of Conferences, 2019
The effects of different initial pH value, temperature and heating time on sludge dewatering performance were studied by treating sludge with acid-heat combination at low temperature and taking dewatering rate (amount of filtrate per unit time) and ...

SiC/Si ceramic hollow fibres: A new approach to Chlorella vulgaris biomass harvesting

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Efficient harvesting of microalgae is a critical challenge for the viability of biorefineries, requiring technologies that combine high selectivity, low cost, and scalability. The current work evaluated the performance of an asymmetric hollow fibre ceramic membrane (HF‐SiC70Si30), fabricated by phase inversion and sintered at 1250°C, in the ...

Tunable amylopectin graft copolymers for flocculating and dewatering iron ore tailings

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Polyacrylamide (PAM), the standard flocculant for mining tailings, often produces turbid supernatants and poorly dewatered sediments, limiting water reuse and tailings densification. We synthesized amylopectin‐graft‐poly[(2‐methacryloyloxy)ethyl]trimethylammonium chloride (AP‐g‐PMETAC) copolymers with systematically varied graft frequency (N =
