Comparison and Validation of UV Dose Calculations for Low‐ and Medium‐Pressure Mercury Arc Lamps
A method for calculating UV dose for microbial disinfection that includes a measure of the wavelength‐dependent factors of UV lamp output, quartz sleeve UV transmission, microbial action spectra, and wastewater UV transmission is presented. The method is validated by comparing UV dose–response curves for the disinfection of a secondary effluent achieved using collimated beams of UV light generated from low‐ and medium‐pressure mercury arc lamps. The wastewater UV transmittance is artificially altered as part of the validation process. A simplified and practical method of UV dose calculation that relies only on a measure of the UV transmission at 254 nm is proposed for the disinfection of domestic wastewaters by mediumpressure lamps. The proposed method is validated using wastewater samples obtained from 21 wastewater treatment plants located across North America.
