A Pilot-Scale Study of Flow-through Ultraviolet-Light Emitting Diodes (UV-LEDs) System for Secondary Municipal Wastewater Effluent Disinfection
Abstract
This study investigated the performance of a flow-through UV-LED POE system for disinfecting municipal wastewater secondary effluent. Pilot-scale tests were conducted to determine optimal operating conditions in terms of flow rate and UV wavelength combinations. The inactivation of total coliforms, E. coli, bacteriophage MS2, and HPC bacteria was monitored to evaluate the disinfection efficacy. Results revealed that the inactivation performance was significantly affected by UV transmittance and flow rate. UV wavelength had a minor impact on disinfection performance. The study also estimated the specific energy consumption and cost implications for meeting E. coli limit in wastewater discharge permit. The findings provide valuable insights for the design and optimization of UV-LED POE systems in municipal wastewater treatment, emphasizing the importance of hydraulic residence time, UV wavelength selection, and energy efficiency considerations.
This study investigated the performance of a flow-through UV-LED POE system for disinfecting municipal wastewater secondary effluent. Optimal operating conditions and the influence of UVT, flow rate, and UV wavelength on the disinfection efficacy were identified through inactivation experiments against total coliforms, E. coli, bacteriophage MS2, and HPC bacteria. The estimated specific energy consumption and cost implications were also evaluated.
