Abstract:

Ultraviolet Disinfection systems are becoming more commonplace in the United States as the preferred means of wastewater disinfection before the effluent is discharged. UV disinfection systems can consume between 14 and 23% of a wastewater plant's power budget, so finding methods to reduce energy consumption are critical. One strategy is to modulate the ultraviolet dose based upon three factors: flow, a water quality measurement known as percent ultraviolet transmittance, and lamp power—a strategy called ‘dose pacing’. The City of Grand Rapids, Michigan implemented dose pacing several years ago, and comparing data from January 1, 2010 to October 16, 2010 showed that a flow pacing strategy could cost up to 190% more than a dose pacing strategy.
