Techniques

Chapter 1: Techniques

1.1 Traditional DAF Skimming Techniques

Dissolved Air Flotation (DAF) is a proven technology for removing suspended solids from water. This process relies on the principle of injecting tiny air bubbles into wastewater, which attach to suspended particles and float them to the surface. The efficiency of this process is heavily dependent on the effectiveness of the skimming mechanism used to collect the floated material.

Traditional DAF skimming techniques often employ mechanisms like:

• Surface Skimmers: These utilize rotating blades or brushes to collect the floated solids. However, they can create turbulence, leading to re-entrainment of settled particles and reduced efficiency.
• Belt Skimmers: While efficient, these systems require regular cleaning and maintenance to prevent clogging.
• Trough Skimmers: These involve a simple collection trough, but they can be less efficient and may lead to uneven skimming.

1.2 The Spiral Scoop: A New Approach

The Spiral Scoop, developed by Krofta Engineering Corp., revolutionizes DAF skimming with its unique helical design. This gentle sweeping motion ensures efficient collection of floated solids while minimizing turbulence and water disturbance, resulting in:

• Enhanced skimming efficiency: The helical design ensures a continuous and consistent flow of floated material into the collection trough, maximizing the removal of suspended solids.
• Reduced re-entrainment: The gentle sweeping motion minimizes turbulence and water disturbance, preventing re-entrainment of settled particles and maintaining optimal separation conditions.
• Minimized disturbance: The Spiral Scoop operates with minimal disturbance to the water below, promoting stable flotation and optimal separation.
