Chapter 1: Techniques

Buoyant Media Flocculation: The Heart of Tricon

The Tricon system's core innovation lies in its buoyant media flocculator/clarifier. This technology utilizes a bed of lightweight, buoyant media, typically plastic or glass beads, suspended within a basin. The media serves several key functions:

• Increased Surface Area: The buoyant media provides a massive surface area for flocculation, allowing for effective contact between suspended particles and chemical coagulants. This leads to faster and more complete aggregation of smaller particles into larger, settleable flocs.
• Gentle Agitation: The media is gently agitated, creating a controlled upflow current. This action prevents settling of the media and ensures proper mixing for optimal flocculation.
• Sedimentation and Clarification: As the water flows upward through the media bed, the heavier, flocculated particles settle down due to gravity, leaving clearer water to exit the top of the basin.

The Tricon Process: A Step-by-Step Approach

1. Coagulation: The raw water enters the Tricon basin where it is mixed with chemical coagulants, such as aluminum sulfate or ferric chloride. These coagulants neutralize the surface charges of the suspended particles, allowing them to clump together.

2. Flocculation: The coagulated water then flows through the buoyant media bed. The media provides a large surface area for the particles to collide and form larger flocs. The gentle agitation of the media further promotes flocculation.

3. Clarification: The water with the larger flocs flows upward through the media bed. The flocs settle down due to gravity, leaving behind clarified water.

4. Sludge Collection: The settled flocs are collected at the bottom of the basin as sludge. This sludge can be further treated and disposed of or used in beneficial reuse applications.

Advantages of Buoyant Media Flocculation:

• High Efficiency: The increased surface area and gentle agitation provided by the buoyant media significantly enhance flocculation and clarification, leading to high removal rates of suspended solids.
• Compact Design: The buoyant media system requires less space compared to traditional sedimentation basins. This is particularly beneficial in locations with limited land availability.
• Low Maintenance: The buoyant media is relatively inert and requires minimal maintenance. This translates to operational cost savings.
• Adaptability: Buoyant media flocculation can be tailored to various water treatment applications, including municipal water treatment, industrial wastewater treatment, stormwater management, and drinking water treatment.

Limitations and Considerations:

• Media Degradation: Over time, the buoyant media may degrade due to wear and tear, requiring replacement.
• Sludge Handling: The sludge generated by the Tricon system needs to be properly treated and disposed of.
• Chemical Requirements: Effective flocculation requires careful monitoring and adjustment of chemical coagulants, ensuring the right balance for optimal performance.
