Water Supply Reservoirs provide an opportunity to improve the quality of water that enters a water treatment plant. Management of the reservoir by Layer Aeration, Hypolimnetic Aeration, Oxygenation, Depth-Selective Flow Routing, Focused Treatments, and other approaches can control raw water quality, improve potable water treatment efficiency, and avoid treatment problems such as:
- Avoid Taste and Odor Episodes (Geosmin and MIB from benthic and phytoplanktonic algae)
- Prevent Iron and Manganese from entering the treatment plant in raw water.
-
Reduce Total, Dissolved, and Assimilative Organic Carbon that causes problems with disinfection byproduct formation, enhanced coagulation, and distribution system re-growth.
-
Avoid fluctuations in pH, temperature, carbon dioxide, and buffering capacity which requires frequent adjustments to treatment.
- Avoid excessive filter backwash frequency and GAC substrate changes.
