Exercise:

Imagine you are a water treatment engineer tasked with designing a system for a small community. The water source contains high levels of suspended solids and a noticeable chlorine odor. You need to select appropriate equipment from the Welles product line to address these issues.

Tasks:

Identify the specific Welles products that could be used to remove suspended solids.
Choose a Welles product to remove the chlorine odor.
Explain why you chose each specific product, highlighting its advantages.
Briefly describe how these chosen products would be integrated into a complete water treatment system.

Exercice Correction

1. **Sand Filters:** These are effective for removing suspended solids from water. 2. **Dechlorination System:** This will remove the chlorine odor and ensure safe drinking water. **Explanation:** * **Sand Filters:** They are a traditional and reliable method for removing suspended solids. The sand acts as a physical barrier, trapping particles as water passes through. * **Dechlorination System:** These systems employ specialized chemicals or processes to neutralize chlorine residuals in water. They are essential for removing the chlorine odor and ensuring safe drinking water. **System Integration:** The water would first pass through the sand filters, removing the suspended solids. Then, it would be sent to the dechlorination system to remove the chlorine odor. Finally, the treated water would be distributed to the community.
