Chemical flocculants - Kemira
Anionic polyacrylamides are easier to polymerize to very high molecular weights. We produce anionic powder flocculants / polyacrylamides (ADPAM) with anionic charge density ranging from 0-100%. We also offer anionic inverse emulsion (AEPAM)
ANIONIC POLYACRYLAMIDE. Composition: Negatively charged copolymers of acrylamide are widely used as retention aids and dry-strength resins. However, different molecular mass ranges are used for these two roles. Anionic acrylamide copolymer
Polyacrylamide degradation and its implications in environmental systems | npj Clean Water

Polyacrylamide
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). 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
solid/liquid separation applications. The high molecular weight polyacrylamide-based flocculants ensure a highly efficient and cost-effective water treatment. They are supplied as free flowing white powder with varying degrees of ionic
- Can natural coagulants be used in wastewater treatment?
- Flocculants, both organic and inorganic, have long been used in wastewater treatment. The use of natural coagulants/flocculants for water and wastewater treatment has become essential due to the health risks associated with chemical flocculants. Tannin, a natural coagulant, has been suggested as substitute of chemical coagulants.
- Can natural flocculants be used as coagulant aid?
- In addition, the flocculation performance is dependent on the characteristics of the wastewater (pH and type of particles containing in wastewater), consequently, the natural flocculants can be moderately effective and only can be utilized as coagulant aid , .
- Which organic flocculants are used in wastewater treatment?
- Natural organic flocculants like chitosan, cellulose, tannin, starch, gelatin and their derivatives and microbial flocculants have been investigated for their flocculation mechanism in wastewater treatment.
- Are natural flocculants a sustainable technology for water and wastewater treatment?
- Finally, the future prospects, challenges and recommendations are also provided in order to advance the developments of natural flocculants to enable them to be a long-term sustainable technology for water and wastewater treatment. 2. Dyes wastewaters Dyes have been used in practically all spheres of daily life since the beginning of mankind.
