Coagulants and flocculants fact sheet
Aluminium and iron coagulants (like aluminium chlorohydrate (ACH) and ferric chloride) contribute trivalent aluminium ions, Al 3+ and trivalent iron ions, Fe 3+ respectively. Schultz in 1882 and Hardy in 1900, demonstrated the greater the charge
efficiency of Alum and Poly Aluminium chloride popularly known as PAC in purification of water. Though PAC is widely used in other countries its use in India for water purification is not appreciable. The optimum dosage level of the chemicals is
Poly-Aluminium-Chloride (PAC) - 3V Tech
Poly-Aluminium-Chloride (PAC) PAC is a flocculant of new concept, the specific properties of which derive from the action of its basic active constituent, namely Poly Aluminium Chloride. PAC is supplied in form of water solution or as powder,

- What is the price of polyacrylamide (anionic grade) in 2025?
- Thus, after the conclusion of the first quarter of 2025, PAM prices (Anionic Grade) were assessed at USD 3400 per MT. For the Quarter Ending December 2025 North America The market prices of Polyacrylamide moved in a downward direction in the North American market during the fourth quarter of 2025, as per ChemAnalyst Research Team Data.
- How much is polyacrylamide anionic grade in Germany?
- The latest quarter-ending price for Polyacrylamide Anionic Grade in Germany was USD 3425/MT FD Hamburg, underscoring the sustained upward momentum in pricing driven by consistent industrial demand and regulatory pressures. The quarter was devoid of major plant shutdowns or operational disruptions, ensuring a stable supply amid rising demand.
- Why are polyacrylamide prices rising?
- Polyacrylamide (PAM) prices have jumped as a combination of a cessation of manufacturing services in China in third quarter of 2021. Midst of it, an extended rise in energy prices, puts an unsustainable strain on imports to India. Moreover, dealers claimed that material shortage forced them to adjust their offers in order to maintain their margins.
