Chlorine Dioxide | Use, Benefits, and Chemical Safety Facts
Chlorine dioxide (ClO2) is a chemical compound consisting of one chlorine atom and two oxygen atoms. It is a reddish to yellowish-green gas at room temperature that dissolves in water. It is used for a variety of antimicrobial uses, including
For drinking water treatment chlorine dioxide can be used both as a disinfectant and as an oxidizing agent. It can be used for both pre-oxidation and post-oxidation steps. By adding chlorine dioxide in the pre- oxidation stage of surface water t

- How much does polyacrylamide cost in the US?
- North America The prices of Polyacrylamide declined in the USA market during the third quarter of 2025, with cost ranging at USD 2252/tonne Polyacrylamide Anionic Grade FOB Texas with a quarterly decline of 11.1% as per recorded by ChemAnalyst pricing team data.
- How much cationic polyacrylamide should be used for sludge treatment?
- For sludge treatments, consumption of a cationic polyacrylamide of 5.4 g·kg −1 of total solids is found to be the best economical solution . Several studies were made, following life cycle analyses, to evaluate energy consumption of wastewater treatment (e.g., Tillman et al. , Hospido et al. and Wenzel et al. ).
- 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.
- Why are polyacrylamide (PAM) prices rising?
- Based on our analysis of the US market for the first quarter of 2025, it is evident that Polyacrylamide (PAM) prices have experienced a sharp increase due to the rise in demand from downstream industries and feedstock cost pressures. Despite domestic production operating rates remaining firm, inventory levels have dropped.
