best practices guidance for the use of anionic polyacrylamide
polyacrylamide (pam) chitosan what is anionic polyacrylamide? high molecular weight, water soluble molecule formed by polymerization of negatively charged acrylamide co-monomer. pam aids solid-liquid separation by causing suspended particles to bind and form larger aggregates. the process is known as polymer bridging.
biopolymer-based flocculants a review of recent technologies,biopolymer-based flocculants have become a potential substitute for inorganic coagulants and synthetic organic flocculants due to their wide natural reserves, environmental friendliness, easy natural degradation, and high material safety. in recent years, with more and more attention to clean technologies, a lot of researches on the modification and application of biopolymer-based flocculants
- What are cationic polyacrylamide copolymers?
- Cationic polyacrylamide copolymers (PAM) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).
- Which polyacrylamide adsorbate contains ionizable carboxyl groups?
- Two types of polyacrylamide ( Korona) differing in the ionic group contents were applied as the adsorbate in the study. The first one—anionic polyacrylamide (AN PAM) contained 30% of the ionizable carboxyl groups whereas the cationic polyacrylamide (CT PAM)—35% of the quaternary amine groups.
- What is the difference between cationic adsorbate and anionic polyacrylamide?
- The first one—anionic polyacrylamide (AN PAM) contained 30% of the ionizable carboxyl groups whereas the cationic polyacrylamide (CT PAM)—35% of the quaternary amine groups. The average molecular weight of the adsorbate was equal to 13,000 and 7000 kDa, respectively.
- What are the different types of polyacrylamide (PAM)?
- Polyacrylamide (PAM) is a kind of linear water-soluble polymer, which is the most commonly used water treatment agent in our sewage treatment! In our practical application, PAM can be divided into cationic, anionic and non-ionic three types. How to choose these three types of PAM, we should start from the differences!
