Exercise: Robo-Screen Design
Imagine you are designing a Robo-Screen for a small wastewater treatment plant. Consider the following factors:
- Volume of wastewater: The plant processes 500,000 gallons of wastewater per day.
- Debris types: The wastewater contains a mixture of large debris, including branches, plastic bottles, and food waste.
- Space limitations: The treatment plant has limited space for installing the Robo-Screen.
Your task:
- Determine the necessary bar spacing based on the debris types.
- Propose a design for the automated cleaning mechanism.
- Explain how you would incorporate space-saving features in your design.
Write a short paragraph describing your design and the reasoning behind your choices.
Exercice Correction
For this small plant, a bar spacing of 2-3 inches would be suitable to effectively remove large debris like branches and plastic bottles. The automated cleaning mechanism could utilize a rotating rake system with adjustable speed to efficiently collect and transport the trapped debris. To maximize space, the Robo-Screen can be designed in a compact vertical configuration, utilizing the height of the treatment plant instead of occupying valuable floor space. This vertical design would also reduce the footprint of the system, minimizing its impact on the plant's overall layout.
