Measurement of treatment agent in a process stream using ultraviolet-visible (UV-vis) spectroscopy, and related systems and processes

摘要

The present application provides a method of detecting an amount of a treatment agent, such as a flocculating agent, in a process stream comprising the step of measuring at least one absorption property of a sample obtained from the process stream at a wavelength of less than about 250 nm. Processes and systems for monitoring and regulating addition of treatment agents to process streams are also provided.
