EFFECTIVE MIXING FOR CHLORINATION AND DECHLORINATION SYSTEMS

The concept of mixing is a critical element of chlorination and dechlorination systems for modern disinfection systems. The essential mixing criteria are based upon mixing characteristics that are plant and application specific. Dechlorination systems rely on adequate dispersion to provide maximum contact. Evaluation of available mixing technologies which can maximize the overall performance of the chemical process can include research on conventional technologies such as mechanical mixing devices, hydraulic jet diffusers, and hydraulic structures such as weir and flume design. Theoretical mixing gradient levels for systems can become useless if the plant flow characteristics are modified. Effective mixing design should also include evaluation of chemical injection techniques to minimize chemical and energy usage.
