Preparation and performance of a novel starch-based inorganic/organic composite coagulant for textile wastewater treatment
TL;DR: In this paper, a novel inorganic/natural polymer composite PAFC-Starch-g-p(AM-DMDAAC) (polyaluminum ferric chloride-starch graft copolymer with acrylamide and dimethyl diallyl ammonium chloride) was prepared, and applied for textile wastewater treatment.
Journal ArticleDOI
Rice straw biochar modified by aluminum chloride enhances the dewatering of the sludge from municipal sewage treatment plant.
TL;DR: The effectiveness of using the modified RSB to enhance the dewatering of the sludge is substantial and promising and performs significantly better than that of the raw RSB.
Journal ArticleDOI
Insight into the improvement of dewatering performance of waste activated sludge and the corresponding mechanism by biochar-activated persulfate oxidation
TL;DR: Three-dimensional fluorescence spectroscopy for EPS proved that the disintegration of tryptophan protein and humic acid was responsible for the improvement of WAS dewatering, demonstrating that the biochar-activated persulfate oxidation was a feasible application in improving WAS de watering.

Optimization of flocculation conditions for soluble cadmium removal using the composite flocculant of green anion polyacrylamide and PAC by response surface methodology.
Zhao Caifeng,Sai Shao,Yaoyu Zhou,Yahui Yang,Shao Ying,Leping Zhang,Yiji Zhou,Linian Xie,Lin Luo +8 more
TL;DR: Results from these studies demonstrated that PAC had a greater capability to change the Zeta potential of collide under alkaline conditions, while APAM played a critical role in the bridging, enmeshment, and sweeping effect.
Journal ArticleDOI
Feasibility and Mechanism of Combined Conditioning with Coagulant and Flocculant To Enhance Sludge Dewatering
TL;DR: In this article, the feasibility of applying the coagulation-flocculation process using PACl and BF-ADSW for sludge dewatering and the related mechanism were explored.

A rapid and sensitive method for the quantitation of microgram quantities of protein utilizing the principle of protein-dye binding
TL;DR: This assay is very reproducible and rapid with the dye binding process virtually complete in approximately 2 min with good color stability for 1 hr with little or no interference from cations such as sodium or potassium nor from carbohydrates such as sucrose.
Journal ArticleDOI
Stratification structure of sludge flocs with implications to dewaterability.
TL;DR: The results suggest that PN and PN/PS in the supernatant and slime layers, which are usually decanted due to their assumed lower content of organic matter, markedly impact sludge dewaterability.
Journal ArticleDOI
Bioflocculant production by culture of Serratia ficaria and its application in wastewater treatment
TL;DR: The bioflocculant was found to be effective for flocculation of a kaolin suspension over weakly acidic pH (5-7); divalent cations enhanced the flocculating activity, while the co-presence of Al3+ and Fe3+ resulted the negative effect.
Journal ArticleDOI
The potential role of aluminium in Alzheimer's disease.
TL;DR: The article discusses the role of aluminium in two mechanisms that have been linked to neurodegenerative disorders, including AD, and suggests that long-term exposure to supra-physiological amounts these metals should be avoided.
Journal ArticleDOI
Production of a novel bioflocculant by Bacillus licheniformis X14 and its application to low temperature drinking water treatment.
TL;DR: This novel bioflocculant ZS-7 produced by Bacillus licheniformis X14 showed good flocculating performance and industrial potential for treatment of low temperature drinking water, and the maximum removal efficiencies of COD(Mn) and turbidity were 61.2% and 95.6%, respectively, which were better than conventional chemicalFlocculants.
