Scenario: A municipality is facing challenges with high levels of iron and manganese in its water supply. They are considering using PakTOR technology to remove these contaminants.
Task: Research and propose a PakTOR system configuration specifically designed for this application.
Exercise Correction:
A PakTOR system for iron and manganese removal would likely utilize multiple cells with different media types:
Cell 1: Oxidation
Cell 2: Filtration
Number of Cells: The number of cells would depend on the flow rate and concentration of iron and manganese. A higher flow rate or higher contaminant concentration would require more cells.
Flow Rate: The flow rate would be determined by the municipality's water demand. The system should be designed to handle peak water usage periods.
Reasoning: This multi-cell configuration allows for a staged treatment process that effectively removes both iron and manganese. The oxidation step converts the contaminants into filterable forms, and the filtration stage physically removes them. The specific media used would be chosen based on the specific water quality characteristics and desired treatment levels.
