Working Principle of Sedimentation Tanks

Sedimentation tanks function by slowing down water flow to allow suspended solids with gravity higher than water to settle at the bottom. The clarified water then exits, while solids form sludge that can be removed for further treatment. Effective sedimentation depends on controlled flow velocity, adequate detention time, and tank geometry minimizing turbulence.

Types of Sedimentation Tanks include:

• Horizontal Flow Rectangular Tanks: Water flows in a straight line, with mechanical scrapers removing sludge continuously.
• Circular Settling Tanks: Radial flow from center to periphery; central scraper arms collect sludge.
• Lamella or Inclined Plate Clarifiers: Series of inclined plates increase settling surface, enhancing efficiency in smaller footprint.
• High-Rate Sedimentation Tanks: Designed for high volume flows with additional flocculation aids.

Design Criteria and Parameters

• Overflow Rate (Surface Loading Rate): Discharge per surface area in m³/m²/day, controls settling efficiency.
• Settling Velocity: Particles’ settling speed must exceed overflow velocity for effective removal.
• Detention Time: Time water stays in tank, typically 4-8 hours for effective sedimentation.
• Tank Dimensions: Width, length, depth optimized to balance flow velocity and retention time.

Advantages of GFS Sedimentation Tanks by Center Enamel

• Corrosion Resistance: Glass enamel coating prevents chemical attack from contaminants and sludge.
• Durability: Steel substrate provides robust structural support.
• Low Maintenance: Smooth, inert glass surfaces inhibit sludge adhesion and facilitate cleaning.
