Removal of water-borne bacteria by coagulation and sedimentation using sawdust coated with an equimolar copolymer of N-benzyl-4-vinylpyridinium chloride with styrene

Strong biodegradability of vinyl polymers exerted by insertion of N-benzyl-4-vinyl-pyridinium halide into the main chain

“…Coagulation and sedimentation of bacterial cells was also realized by addition of sawdust that was coated with 1 weight % of equimolar copolymer of styrene with BVP(Cl) [19]. When the coated sawdust was mixed with suspension of E. coli and allowed to stand, the coated sawdust precipitated and the bacterial cells formed flocks and accumulated over the precipitated sawdust, and bacterial population in the supernatant layer reduced to 1/1,000,000 or less during the procedure under appropriate conditions.…”

Syntheses of biodegradable vinyl polymers by insertion of N-benzyl-4-vinylpyridinium chloride into the main chain

“…Tomato bacterial wilt was suppressed by coagulation of bacterial cells using a copolymer of BVP with methyl methacrylate [19]. Sawdust coated with a copolymer of BVP with styrene was used to remove water-borne bacteria by coagulation and sedimentation [20].…”

Community engagement, environmental education, and public outreach in sustainable engineering : a collaborative demonstration project for water treatment using natural processes and sustainable materials.

“…The resulting reaction binds sediment particles together, or coagulates them, forming a mass called the floc (Ayguna, A. 2010 show that sedimentation and coagulation remove some pathogens that are attached to suspended substances (Kawabata, N., 2005).…”
