Techniques

Chapter 1: Techniques

Clariflo: A Deeper Dive into Clarification Techniques

This chapter delves into the specific techniques employed by Clariflo systems for water and wastewater treatment. These techniques, often working in tandem, ensure the efficient removal of suspended solids, resulting in cleaner water.

1.1 Gravity Settling:

The core principle of Clariflo is gravity settling. This involves the natural tendency of denser particles to settle out of a fluid when gravity is the dominant force. The Clariflo design optimizes this process.

1.2 Lamella Plates:

Clariflo systems commonly incorporate lamella plates, inclined plates that increase the surface area available for settling. By creating a multitude of small settling zones, lamella plates significantly enhance the removal of fine particles, which would otherwise remain suspended. This translates to a more efficient removal process.

1.3 Dissolved Air Flotation (DAF):

In some Clariflo applications, especially industrial wastewater treatment, DAF technology plays a vital role. DAF involves the injection of fine air bubbles into the water stream. These bubbles attach to the suspended solids, making them buoyant. As a result, the solids rise to the surface for easy removal, ensuring a more thorough treatment.

1.4 Coagulation and Flocculation:

These chemical processes often precede the Clariflo stage. Coagulation involves adding chemicals that cause small particles to clump together. Flocculation uses other chemicals to bind these clumps into larger, heavier flocs, making them easier to settle out in the Clariflo unit.

1.5 Sludge Removal:

The settled solids, or sludge, are collected at the bottom of the Clariflo unit. This sludge is then either discharged for further treatment or recycled within the system for optimal efficiency.

1.6 Clariflo Advantages:

The combination of these techniques within the Clariflo system results in several significant advantages:

• High-rate clarification: Achieving high settling rates, reducing the required tank size and construction costs.
• Fine particle removal: Lamella plates effectively remove fine particles, improving water quality.
• Effective sludge removal: Efficiently capturing and removing sludge, minimizing the discharge of pollutants.
• Flexibility and Adaptability: Clariflo systems can be tailored to suit diverse needs, adapting to different water sources and treatment objectives.

The Clariflo system's innovative techniques offer a practical and efficient approach to water and wastewater treatment, contributing to cleaner water and a healthier environment.
