Helaskim Exercise:

Scenario: A food processing plant generates wastewater containing high levels of fats, oils, and greases (FOG). The current treatment system struggles to effectively remove FOG, leading to sewer blockages and environmental concerns.

Task: Explain how a Helaskim could be integrated into the food processing plant's wastewater treatment system to improve FOG removal efficiency. Consider the following factors in your explanation:

• How the Helaskim works
• Advantages of using a Helaskim for FOG removal
• Potential improvements in efficiency and environmental impact

Techniques

Chapter 1: Techniques

Helaskim: A Revolution in Oil & Grease Removal

Helaskim, a revolutionary surface skimmer developed by Walker Process Equipment, utilizes a helical design to effectively remove oil and grease from wastewater. This technique combines the benefits of both slotted and centrifugal skimmers, offering superior performance and versatility.

The helical design:

• Continuous, upward flow of water: The rotating helical shaft creates a continuous upward flow of water, drawing oil and grease towards the surface.
• Oil and grease concentration: The helical surface forces the oil and grease to accumulate along the inner wall of the housing, creating a concentrated layer.
• Scraping and collection: A rotating blade scrapes the concentrated oil and grease layer and conveys it to a collection trough for further processing.

Advantages of the helical technique:

• High efficiency: The helical design optimizes oil and grease collection, maximizing removal efficiency even at low concentrations.
• Versatility: Helaskims can handle a wide range of oil and grease types, including light and heavy oils, as well as fats and greases.
• Low maintenance: The robust construction and simple design minimize wear and tear, requiring minimal maintenance.
