Techniques

Chapter 1: Techniques

Chemical Feed Techniques in Water Treatment

Silo Pac systems utilize various chemical feed techniques, tailored to the specific chemical being used and the application.

1. Dry Chemical Feeding:

• Powdered or Granular Chemicals: Silo Pac handles dry chemicals through pneumatic or mechanical conveying systems.
• Pneumatic Conveying: Air pressure is used to transport the powder from the storage silo to the point of application.
• Mechanical Conveying: A screw feeder or auger system is used to move the dry chemicals.
• Dosing: The dry chemicals are typically dissolved in water before introduction to the treatment process.

2. Liquid Chemical Feeding:

• Direct Injection: Liquids are pumped directly into the treatment process.
• Dilution and Injection: Liquids are diluted with water before injection, to achieve the desired concentration.
• Metering Pumps: Accurate dosing of liquids is achieved through metering pumps, ensuring precise chemical delivery.

3. Slurry Feeding:

• Slurries of Solids: For chemicals that don't dissolve easily in water, slurry feeding is used.
• Mixing and Transport: The chemicals are mixed with water to form a slurry and then transported through a dedicated system.
• Dosing: The slurry is injected into the treatment process using a specially designed pump.

4. Chemical Feed Control:

• Flow Proportional Control: The chemical feed rate is adjusted based on the water flow rate.
• Time Proportional Control: The chemical feed rate is adjusted based on a predetermined time schedule.
• Feedback Control: The chemical feed rate is adjusted based on the real-time measurement of a water quality parameter, like pH or chlorine level.

5. Safety Features:

• Emergency Shut-Off Valves: These valves automatically stop chemical feed in case of an emergency.
• Pressure Relief Valves: Prevent excessive pressure buildup in the system.
• Leak Detection Systems: Alert operators to any chemical leaks.
