Eautec Raw Water Treatment Coagulant & Flocculant Treatment Programme

Coagulants and flocculants are essential chemicals used in raw water treatment to remove suspended solids, turbidity, organic matter, and other impurities. These chemicals help in the clarification process by aggregating fine particles into larger clumps that can be easily removed through sedimentation or filtration.

 

 

  • Coagulants: Positively charged chemicals that neutralize the negative charge of suspended particles, causing them to destabilize and form micro flocs. Common coagulants include aluminium sulfate (alum), ferric chloride, ferric sulfate, and Polyaluminum chloride (PAC).
  • Flocculants: Long-chain polymeric compounds that bridge and bind coagulated particles together into larger flocs, making them easier to settle or filter out. Flocculants are typically polyacrylamides (PAM) and can be classified as anionic, cationic, or non-ionic, depending on the charge required for a specific application.

Advantages:

  • Effective Turbidity Removal: Reduces suspended solids and organic matter for clearer water.
  • Improved Sedimentation & Filtration: Enhances the efficiency of sedimentation and filtration processes.
  • Reduced Chemical Usage: Optimized coagulation-flocculation minimizes the need for additional treatment chemicals.
  • Lower Operating Costs: Reduces sludge volume, energy consumption, and maintenance efforts.
  • Better Disinfection Efficiency: Removes contaminants that interfere with chlorine and other disinfectants.
  • Customizable Formulations: Various coagulants and flocculants can be tailored for different raw water characteristics.

Dosage:

  • Our experts will provide dosing guidelines and monitoring procedures during the treatment implementation.

Storage :

  • Store in a well-ventilated area, away from moisture.
  • Use protective gear (gloves and goggles) to prevent irritation from contact.
  • In case of contact with skin or eyes, rinse thoroughly with water.
  • Refer to the Material Safety Data Sheet (MSDS) for detailed safety guidelines.
