indonesia manufacture water treatment flocculant pam
polyacrylamide is a polymer (-ch2chconh2-) formed from polyacrylamide subunits. it can be synthesized as a simple linear-chain structure or cross-linked, typically using n, n’-methylenebisacrylamide. polyacrylamide is not toxic. in the cross-linked form, the possibility of the monomer being present is reduced even further.

polyacrylamide.polyacrylamide (abbreviated as pam or pam) is a polymer with the formula (-ch 2 chconh 2-). it has a linear-chain structure. pam is highly water-absorbent, forming a soft gel when hydrated. in 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.
recent achievements in polymer bio-based flocculants for low cost
among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (pam)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [8,9,10]. the acrylamide monomer can be used for grafting or crosslinking of other type of polymers.

- What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
- Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
- Which cationic polymers are used as flocculants for silica aggregates?
- An example is work by Zhou and Framks [ 31 ], where three cationic polymers (homopolymer of diallyldimehylammonium chloride and its two copolymers with acrylamide) of different molecular weights (1.1–3.0 × 10 5 g/mol) and charge density (CD) (10%, 40%, and 100%) were used as flocculants for silica aggregates.
- Can polyanion reduce cationic flocculants?
- According to ref. , even the inclusion of a little polyanion can considerably reduce the flocculating action of cationic flocculants. This suppressive effect can be explained by a decrease in the effective collision radius induced by the swollen polymer coil shrinking because of an oppositely charged polymer link.
- Which cationic polymer is used in direct flocculation?
- In direct flocculation, medium charge density with high molecular weight cationic polymers is normally used. It has dual functions: (1) neutralise the negative charges of the colloidal particles and (2) bridge the aggregated destabilised particles together to form flocs ( Chong, 2012 ).
