The flocculation efficiency of polydisperse polymer flocculants
The flocculation performance of three poly(acrylic acid) (PAA) samples (Mw = 9 10, 2.5 10 and 1 10 g/mol) has been investigated. Colloidal alumina particles were used as a model system and tests were performed at pH 5. Using a singlecomponent polyacid, it was found that the optimum dosage required to achieve supernatant clarity was similar between the 9 10 g/mol PAA (23 ppm) and 2.5 10 g/mol PA...
متن کاملFlocculants—an Ecofriendly Approach
Although water-soluble synthetic polymers find wide applications as flocculants, the potential problem associated with their use is lack of biodegradability and high cost. Polysaccharides owing to their distinctive features like ability to undergo different chemical reactions, biodegradability and sustainability inspire hope to obtain effective, economical viable and safe substitute of the synt...

متن کاملPOLYACRYLAMIDE FLOCCULANTS IN JUICE CLARIFliCATION
The importance of various factors relating to the preparation of polyacrylamide flocculant solutions was investigated. For optimum results, these solutions should be agitated for at least 2 hours before use while water of high ionic content should be avoided. The quantity of calcium phosphate precipitated during the clarification reaction and the calcium concentration in clear juice are shown t...
