polyacrylamide polymer bio-based flocculants for water treatment
another factor is the appropriate flocculation time, which depends on the type and amount of impurities in the solution and the kind of flocculant. since the size, shape, density, and speed of sediment settlement change over time, the changing hydrodynamics of sediments also affects the course of flocculation [ 76 , 77 ].
anionic polyacrylamide (apam) yongruida activated carbon,pac/pam; anionic polyacrylamide (apam) anionic polyacrylamide is produced when acrylamide is polymerized with an anionic comonomer. water soluble polyacrylamide have been used for decades to facilitate solidliquid separations in wastewater and drinking water treatment, the pulp and paper industry, aquaculture, and many other industrial processes.

water flocculant powder clarification veolia
some types provide rapid, mechanical mixing and rely on flow turbulence for flocculation; others eliminate the rapid mix stage and provide only moderate turbulence for flocculation. however, in most cases, users can overcome rapid mix deficiencies by adding the primary coagulant further upstream of the clarifier.
