Project Summary: Ultraviolet Disinfection of a Secondary Effluent. Measurement of Dose and Effects of Filtration

摘要

Ultraviolet (UV) disinfection of wastewater secondary effluent was investigated in a two-phase study to develop methods for measuring UV dose and to determine the effects of filtration on UV disinfection. The first phase of the study involved a pilot plant study comparing filtration, water quality parameters, and two reactors. The pilot plant study led to laboratory experiments involving: (1) the development of a method for in situ measurement of intensity using a calibrated bioassay, (2) experimental verification of a method for calculating intensities, (3) evaluation of the role of lamp spacing in dose efficiency, and (4) simulation of UV disinfection in continuous flow.
