Chapter 1: Techniques

HeliSkim: A Revolutionary Approach to Surface Skimming

The HeliSkim system utilizes a unique helical rotor design, which sets it apart from traditional skimming methods. The rotor, positioned within the wastewater, rotates at a specific speed, creating a continuous, controlled vacuum. This vacuum draws in floating materials, like oil, grease, and debris, from the water surface.

Advantages of the Helical Rotor Design:

  • Efficient Removal: The continuous circular motion of the rotor ensures maximum contact with the water surface, leading to a high removal rate of floating materials.
  • Self-Cleaning: The helical rotor's design allows for self-cleaning, reducing the need for manual intervention and minimizing downtime.
  • Adjustable Skimming Depth: The rotor's positioning can be adjusted to accommodate varying depths of floating materials, ensuring optimal removal efficiency.

Comparison with Traditional Skimming Techniques:

  • Traditional Skimming: Often relies on mechanical arms or belts that move across the surface, potentially causing disturbances in the wastewater flow.
  • Helical Skimming: Offers a more efficient and controlled approach, minimizing disturbance and maximizing removal efficiency.
