Adams, Jeff. US EPA Testing of LP & MP UV Disinfection Technologies. Presented at 11th Annual EPA Drinking Water Workshop, Cincinnati, OH, September 09 - 11, 2014.
Impact/Purpose:
presentation at the 2014 EPA Drinking Water Workshop
Description:
Presentation will discuss the ongoing USEPA research on UV disinfection addressing the following objectives: Conservatively predict log inactivation and RED of adenovirus with surrogates; Conduct many (LP=61) UV reactor conditions challenged with Ad2, B. pumilus, and MS2 & conduct CBs each day testing; Assess simplified methods for propagation & assay of B. pumilus and Ad2; Evaluate biodosimetry data using combined variable S/S0/Q/DL; Generate dose delivery algorithms for reactor monitoring (calc dose & hybrid setpoint); Compare VF determination by UVDGM method vs a simplified approach; Utilize novel UV duty-sensor technology in MP reactor validation testing that includes lower (<240nm) UV wavelength monitoring in which new sensor implementation will be useful for Crypto, Giardia, Adeno applications; Conduct microbial challenge reactor runs varying conditions with full-spectrum MP-UV and also 219 Q-sleeves to evaluate low/high UV wave contributions; Evaluate dose-delivery algorithms incorporating low/high UV wavelength sensor data and ASCF.
