Question
What are the chemicals used in potable water treatment? Mention their role in the treatment.
Answer
Chemicals used in potable water treatment and their roles:
- Chlorine: Used for disinfection to kill or inactivate harmful microorganisms.
- Coagulants: Aid in the removal of suspended particles by causing them to clump together, allowing for easier filtration.
- Flocculants: Assist in the formation of larger particles from smaller ones, aiding in the removal of fine particles during sedimentation or filtration.
- pH Adjusting Chemicals: Control and adjust the pH level of water to optimize treatment processes.
- Activated Carbon: Removes organic contaminants, taste, and odour compounds through adsorption.
- pH Indicator Chemicals: Help monitor and maintain the desired pH range during treatment.
