polymer based flocculants review of water purification,polyacrylamide (pam) is the basis for most commercial polymeric flocculants mentioned in the literature (anionic, cationic, or non-ionic); this polymer is also modifiable with combinations of comonomers. anionic pam; the most important category of pam, can be made by copolymerizing acrylamide with acrylic aid or partially hydrolysing
recent advances on coagulation-based treatment of manufacturer
purpose of review the use of conventional chemical coagulant in treatment of wastewater is gaining great attention. drawbacks related to the prolonged effects on human health and environment due to the generation of by-product non-biodegradable sludge are becoming the latest topics. transition from chemical to natural coagulant can be a good strategy to reduce the aforementioned drawbacks

polymers for coagulation and flocculation in water treatment
the classification of the synthetic organic polymers used in water and wastewater treatment operations is based on the ionic charge present, e.g. cationic, anionic and non-ionic polyelectrolytes. cationic polyelectrolytes formed the largest number of polymeric coagulants that have been used in cf operations.

- Is a suspension flocculated or Deflocculated?
- Whether a suspension is flocculated or deflocculated depends on the relative magnitudes of the electrostatic forces of repulsion and the forces of attraction between the particles. At low electrolyte concentration, the electrical repulsive force predominates and particle interactions are maximized.
- How can flocculating agents improve the stability of flocculated suspensions?
- Use of Flocculating Agents: Introducing flocculating agents during the formulation can enhance the stability of flocculated suspensions by promoting the formation of larger, more easily dispersible flocs. 1.
- Can flocculating agents be added to induce flocculation?
- Flocculating agents may be intentionally added to induce flocculation. 2. Deflocculated Suspension Definition: In deflocculated suspensions, the solid particles repel each other due to electrostatic forces, resulting in a more stable dispersion without significant aggregation.
- How can I improve the stability of a flocculated suspension?
- 1. Redispersion: Gentle agitation or stirring before use can help redisperse the flocs and maintain a more uniform suspension. 2. Use of Flocculating Agents: Introducing flocculating agents during the formulation can enhance the stability of flocculated suspensions by promoting the formation of larger, more easily dispersible flocs.
