This paper investigates the effect of controlled periodic illumination by visible LEDs on the performances of a flat-plate photocatalytic reactor for wastewater treatment. Different LED dimming techniques are investigated and compared, including the classical Pulse Width Modulation (PWM) technique and a novel proposed VariablePeak PWM technique. A modulation of dimming duty-cycle is adopted as well, which allows to control the light irradiation in a new way with respect to previously used methods. Experimental results highlight the improvement in the photocatalytic degradation process obtained by using the proposed modulation techniques.

Abstract

This paper investigates the effect of controlled periodic illumination by visible LEDs on the performances of a flat-plate photocatalytic reactor for wastewater treatment. Different LED dimming techniques are investigated and compared, including the classical Pulse Width Modulation (PWM) technique and a novel proposed VariablePeak PWM technique. A modulation of dimming duty-cycle is adopted as well, which allows to control the light irradiation in a new way with respect to previously used methods. Experimental results highlight the improvement in the photocatalytic degradation process obtained by using the proposed modulation techniques.
