Blending supplies for plant optimization
When water supplies are combined, a blend based on a target source water parameter rather than quantity alone can help optimize plant performance.
The Corpus Christi, Texas, water treatment plant treats water from the Nueces River watershed. In the fall of 1998, the plant will begin receiving water from Lake Texana, a source with very different water quality. A comprehensive treatability study was conducted to prepare the plant for the new water. In evaluating the desirability of treating a given blend and selecting an optimum blend to target for treatment, the authors considered several factors, e.g., amount of chemicals required, range in chemical dosages required, settled and filtered water quality, and compliance with the proposed enhanced coagulation regulations. The authors proposed that the optimal blend for Corpus Christi be identified by alkalinity and achieved by targeting a range of alkalinity in the raw water. In general, selection of a blend based on a target source water parameter may result in creation of a more consistent source water than is achievable by blending based on quantity alone, thereby increasing the potential for optimizing plant performance.
