2022 IUVA Americas Conference: Sunday Program

Sunday, September 25

1:00-4:30 PM
Workshop: Fundamentals of UV process and equipment validation
Organizer: Dr. Tatiana Koutchma, Agriculture and Agri-Food Canada

Validation is one of the core activities involved with establishing ultraviolet (UV) light processes and demonstrating pre-determined system performance and safety. There are multiple terminologies and approaches for “validation”, “verification” and “monitoring” defined by regulatory organizations and professional associations that include different tasks. It is important to keep all these tasks separate and to understand their role.

Additionally, the efficacy of existing UV light sources against different groups of organisms varies in different matrices such as air, water, surfaces or fluid foods and require different experimental approaches. Despite the broad range of commercial applications of UV light technologies, the level of commercialization differs depending on the application and light source. The validation approaches and procedures are well established and accepted for water and air treatment but require more knowledge in other developing areas such as surfaces and food disinfection. It is important that the key knowledge of established validation procedures could be used efficiently for faster implementation of new UV applications.

The workshop is developed for professionals working at developing and commercializing UV technologies in various fields including air, water, surfaces and food disinfections.

Attendees will learn:

  1. Fundamentals of UV light technology, key principles and steps of process and equipment/device validation, verification and monitoring
  2. Established practices, UV sources, approaches and lessons of microbial validation of water and air UV disinfection.
  3. How existing experience, lessons and challenges of commercialized process and systems validation can be efficiently applied for new applications
