recent achievements in polymer bio-based flocculants for sale,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.
polyacrylamide (pam), polyacrylamide powder, polyacrylamide
polyacrylamide (pam) is commonly used as a flocculant in water wastewater treatment, pulp and paper production, agriculture, food processing and mining. which is based on polyacrylamide copolymers providing the complete range of ionicities and molecular weights necessary to meet optimal performance for each applications.
polymer based flocculants review of water purification,longer polymer chains in flocculants with high mw can adsorb onto the surface of several particles at once, whereas macromolecules with lower mws adhere to fewer particles. as a result, as compared to low mw polymers, high mw flocculants can achieve quicker solid settling rates. polymer mw can have a significant impact on flocculation efficacy.

high performance, cost-effective and ecofriendly flocculant,moreover, the cis flocculant showed excellent flocculation effects in ambient ph of 4-10, flocculation temperature of 10-40 °c, and various inorganic salts. in general, the anionic cis flocculant shows excellent cost effectiveness, where the predicted operation cost of as-prepared cis is about 60 % of conventional polyacrylamide flocculant.
- Which flocculants are used in wastewater treatment?
- Inorganic and organic polymer flocculants are the most common flocculants used in wastewater treatment. Inorganic flocculants are mostly made up of aluminium and iron, and they have a strong treatment effect on suspended solids and colloidal particles, but they have some disadvantages.
- Are plant-based bioflocculants a viable alternative to synthetic flocculants?
- Because of their non-toxic and biodegradable nature, plant-based bioflocculants have become popular as an alternative to synthetic flocculants in wastewater treatment. They are abundantly available from renewable resources and have no negative environmental effects ( Lee et al. 2014 ).
- Can biopolymer-based flocculants improve the treatment of heavy metal ions sewage?
- Up to now, flocculation technology based on biopolymer-based flocculants has been able to enhance the treatment of heavy metal ions sewage. Firstly, with the aid of biopolymer-based flocculants, the flocculation performance of inorganic coagulants on heavy metal ions could be improved.
- How do flocculants affect water treatment efficiency?
- As the core of flocculation, flocculants’ characteristics directly determine the efficiency of water treatment (Liao et al. 2014 ). According to the chemical composition, the flocculant can be divided into inorganic coagulants and organic flocculants.
