Impact of Biodosimetry-Based Validation on UV System Design Specifications

The need for a modern, industry standard protocol for the validation of UV systems used for the disinfection of wastewater effluents has become increasingly evident. Whilst the development of a modified validation protocol is an important first step in the advancement of wastewater UV disinfection, it is one of several key components that are required for the successful implementation of advanced methods for UV system design and operation. Many concepts that are key to the proper application of biodosimetry-based validation models in the design of UV systems are commonly misunderstood or overlooked. A keen understanding of the impact of various validation methods on the sizing of UV reactors coupled with modern approaches for the development of UV system disinfection requirements will equip engineers with the necessary tools to develop appropriate design specifications and properly evaluate UV system designs in order to ensure safe and efficient disinfection of wastewater effluents.
