Task: You are a water treatment engineer designing a new rectangular clarifier for a municipal wastewater treatment plant. The clarifier will be 100 feet long and 20 feet wide. You need to choose a Drag-Star system that meets the following requirements:
Instructions:
The ideal Drag-Star model for this scenario would be one with a large enough carriage to effectively remove sludge from the entire 100-foot length of the clarifier and a robust cable drive system capable of handling the required load and ensuring minimal downtime. The model should also be customizable to fit the 20-foot width of the clarifier.
Specific model selection would depend on the exact specifications of the available Drag-Star models, which would need to be researched further.
In the justification, you would mention the chosen model's carriage width, scraper blade configuration, motor horsepower, and any other relevant specifications. You would also highlight features contributing to reliability like redundancy in the cable drive system, corrosion-resistant materials, and robust design. You would also describe how the model can be customized to fit the clarifier dimensions, such as adjustable carriage length or track width.
