With rising energy costs and the worsening climate crisis, some wastewater treatment plants have started using solar energy. Because solar adoption at wastewater treatment plants is still relatively new, there is little known about these facilities, including where they are, what drove them to choose solar, and if solar has been a success.
Of these 41, 39 were installed in wastewater treatment plants with a flow rate below 50 mega gallons day (MGD). Only two plants with flow above 50 MGD had solar PV installed. In wastewater treatment plants with a flow rate above 5 MGD, solar PV was primarily installed in hybrid configurations with anaerobic digestion.
Across all the plants analysed, 1 MW was the most adopted solar installation size and solar PV installations were mostly found in wastewater treatment plants in rural settings.
The analysis focused on the effect of three sector-specific influencing factors: size of wastewater treatment plant, presence/absence of anaerobic digestion and geographical location (urban vs rural). Solar PV adoption was observed to vary significantly with the size of the wastewater treatment plants.
The reason is that the aeration tanks in WWTPs are the parts of the plant that use the most energy, accounting for 45% to 75% of the energy footprint. This paper presents a novel
