In this study, a high-efficiency magnetic heavy metal flocculant MF@AA was prepared based on carboxymethyl chitosan and Fe3O4. It characterized by SEM, FTIR, XPS, XRD VSM, the Cu(II) removal rate used as evaluation basis for preparation process. The effects of AMPS content, total monomer concentration, photoinitiator concentration reaction time performance flocculation to remove were studied. c...

Abstract Development of cationic flocculants from lignocellulosic wastes not only eliminates the health and environmental concerns associated with use conventional chemicals, but also is way waste valorization. In present study, cellulose fibers extracted rice husk were cationized through an optimization method based on response surface methodology. The at optimal conditions had a zeta-potentia...

Harvesting can contribute up to 15% of the total production cost for microalgal biomanufacturing. Using flocculants is potentially a cost-effective approach but there has been considerable debate on efficacy, cost, toxicity cell and environment, effect biomass further downstream. In this study, range biobased (chitosan from crab shells, Moringa oleifera seed extract, pectin bananas, tannic acid...

The lack of access to clean water worldwide and organic, inorganic as well biological contamination existing freshwater sources are a major problem for around 2 billion people, especially in the countries global south. One sign polluted is turbidity. It generally caused by colloidal particulate suspended solids. Chemical flocculants often used reduce turbidity thus eliminate mostly harmful subs...

Due its high water content, sewage sludge dewatering is not just a simple operation; rather, it challenging process and costly management task. Its final handling usually preceded by several steps, among them the conditioning known as flocculation stage, which carried out using synthetic chemical reagents. Despite abilities of these additives to reduce volume extract bound waters, they are susp...
