application of flocculants in wastewater treatment
coagulation–flocculation is the conventional treatment method where the cationic inorganic metal salts are commonly used as coagulants and long chains non-ionic or anionic polymers are usually employed as flocculants (chong, 2012). it is generally known that most of the suspended particles in wastewater carry negative charge in aqueous medium.

polymer based flocculants review of water purification,even though man-made polymer flocculants have been the most widely utilised thus far due to their excellent flocculation and low cost, natural ones have the advantages of being manufactured on a large scale and at a lower cost; researchers are studying more bio-based flocculants due to their application having better harmony with climate
flocculants for water treatment balancing safety for free sample
large, anionic pams are the most widely used polymers for water treatment. widespread use is due to low toxicity, high effectiveness and ready availability. pam has also been thoroughly utilized and studied with over 70 years of research and use as a soil amendment and more than 50 years as a water treatment chemical (entry et al. 2002).
simple cationic polyacrylamide a drag reducer iranian,a very simple cationic monomer and a cationic hydrophobically associating polyacrylamide were synthesized, and the polymer was to function as a drag reducer. the structures of monomer and polymer were characterized by ir and nmr, and the drag-reducing rate, below and above the critical association concentration, (cac) was tested. the modified polyacrylamide is a typical hydrophobically
recent achievements in polymer bio-based flocculants for low cost
there are numerous studies on cellulose derivatives of anionic polyacrylamide, cationic polyacrylamide and amphoteric nature, as high-performance polymer flocculants. the flocculation efficiency of anionic cellulose (dicarboxylic acid cellulose, dcc) was examined in the coagulation–flocculation treatment of municipal wastewater.

water soluble polymer flocculants synthesis
polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly(vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7
