Research Summary

Dr. Blatchley has led the development of photochemical reactor theory, and has also made important contributions relative to chemical disinfection processes, including implementation of new analytical methods and definition of kinetics and mechanisms of several important reactions. Applications include drinking water production, wastewater treatment, and swimming pool chemistry. More recently, Blatchley's research group has worked to translate basic principles of water treatment to improve access to potable water in developing countries.
