Task: 1. Identify two potential benefits of using deep bubble aeration to solve the corrosion problem. 2. Explain how these benefits will address the specific concerns of the municipality.
Exercice Correction
**Benefits:** 1. **Corrosion control:** Deep bubble aeration delivers oxygen to the deeper parts of the water column, where corrosion is most likely to occur. This oxygenation helps prevent the formation of corrosive conditions, thereby reducing pipeline deterioration. 2. **Reduced maintenance costs:** By effectively preventing corrosion, the municipality can expect a decrease in the frequency and cost of pipeline repairs and replacements, ultimately leading to significant cost savings in the long run. **How these benefits address the municipality's concerns:** 1. **Reduced maintenance costs:** The primary concern of the municipality is the high cost of maintenance due to corrosion. Deep bubble aeration directly addresses this by reducing the rate of corrosion, thereby decreasing the frequency and expense of repairs. 2. **Improved water quality:** Corrosion can lead to the release of harmful metals into the water, posing a risk to public health. By effectively controlling corrosion, deep bubble aeration helps ensure the delivery of clean and safe drinking water.
