T-Disc Exercise

Scenario: An oil tanker has spilled 100 gallons of crude oil into a harbor. The harbor authorities have deployed several T-Discs to recover the oil. Each T-Disc has a recovery rate of 5 gallons per minute.

Task: Calculate how long it will take for the T-Discs to recover all of the spilled oil if 3 T-Discs are operating simultaneously.

Chapter 1: Techniques

The Power of Hydrodynamic Suction: How T-Discs Work

The T-Disc, a cornerstone of oil spill response and water treatment, relies on the principle of hydrodynamic suction. Unlike traditional skimmers that use surface tension or mechanical forces, the T-Disc draws oil towards a rotating disc submerged in water.

Here's how it works:

1. Water flow: The T-Disc is strategically positioned in the water, allowing the natural water flow to carry oil towards the rotating disc.
2. Disc rotation: The submerged disc rotates at a controlled speed, creating a vacuum effect.
3. Oil adhesion: The oil, being less dense than water, adheres to the rotating disc due to the centrifugal force.
4. Oil collection: As the disc rotates, the accumulated oil is scraped off and transported to a separate collection tank.

This continuous process ensures efficient oil removal, even from low concentrations.

Key Advantages of T-Disc Technology:

• High Recovery Rates: T-Discs achieve significantly higher oil recovery rates compared to other skimming methods, especially in challenging conditions.
• Effective in Thick Oil Slicks: The hydrodynamic suction principle allows T-Discs to effectively remove even thick, viscous oil, something traditional skimmers struggle with.
• Minimal Impact on Water Quality: The submerged design minimizes disruption to the water flow, reducing the risk of secondary pollution.
• Versatile Application: T-Discs are effective across diverse conditions, from calm waters to rough seas and even for recovering oil from enclosed spaces.
