Feedpac Exercise
Scenario:
A water treatment plant is considering using Feedpac for their drinking water treatment process. They currently use a manual dosing system for their coagulants, which often results in inconsistent dosing and potential over-dosing. They are looking for a more reliable and efficient solution.
Task:
- Explain to the plant managers how Feedpac can address their current challenges with manual dosing.
- Outline three key benefits of using Feedpac in their specific application.
- Suggest a specific type of coagulant that might be suitable for their drinking water treatment process and explain why.
Exercice Correction
**1. Addressing Challenges:** Feedpac can solve the plant's challenges with manual dosing by providing a consistent and precise delivery of coagulants. Its automated control system eliminates human error and ensures accurate dosing based on set parameters. This will result in more consistent water quality and reduce the risk of over-dosing, leading to improved efficiency and reduced chemical waste. **2. Key Benefits for the Plant:** * **Improved Water Quality:** Consistent and accurate dosing will result in optimal coagulation, leading to clearer and safer drinking water. * **Reduced Chemical Consumption:** Precise dosing minimizes over-dosing, saving money on chemical purchases and reducing environmental impact. * **Enhanced Operational Efficiency:** Automated control streamlines the process, freeing up staff for other tasks and reducing downtime. **3. Suitable Coagulant:** Polyaluminum Chloride (PAC) is a widely used coagulant for drinking water treatment. It is effective in removing turbidity and suspended solids, and it typically requires lower dosing compared to other coagulants, leading to lower operating costs.
