Ultraviolet (UV) treatment systems have been demonstrated to be effective for control of protozoan parasites (e.g., Cryptosporidium parvum) and for decomposition of chloramine compounds. Collectively, these attributes have led to dramatic increases in the frequency with which UV-based treatment systems have been incorporated into recirculating systems in swimming pool facilities. However, many important misconceptions exist regarding the behavior, strengths, and weaknesses of these reactors.
This class will be structured to provide information about the physical and chemical principles that govern the behavior of UV reactor systems. In turn, this information will be used to interpret information that is currently available to describe the effects of UV systems on air and water chemistry in pools. In addition, information will be included to address the effects of UV systems on microbial quality in pools. Overall, this information will provide class attendees with information about the changes in swimming pool environments that can be expected to result from inclusion of UV-based treatment in a swimming pool facility.
