Photovoltaic energy storage cooperation for sewage treatment plants

Where are solar PV wastewater treatment plants located?

Most of the solar PV adopted wastewater treatment plants are located in California, USA. For wastewater treatment plant capacity of above 5 Million Gallons per day inflow, around 8–30% of its energy demand is met by solar PV modules.

Can wastewater treatment plants be used for solar PV projects?

The potential of using wastewater treatment plants for solar PV projects is found to be economically viable in twenty six urban sites of China. Self consumption of the PV power by the waste water treatment plant and solar radiation potential of the plant plays an effective role in deciding the economic viability of this initiative.

What is the difference between solar energy and wastewater treatment plant?

The solar Energy faces the drawback to treat wastewater only during day time, whereas wastewater treatment plants are underperformed during night. Need for energy storage systems increases the overall cost of the WWT plant.

Are solar PV modules a viable alternative to oxidation tanks?

Colacicco and Zacchei [ 53] suggested solar PV modules to be an effective candidate in meeting the energy demand of oxidation tanks which consumes nearly 30–60% of the entire energy supplied to the wastewater treatment plants. Energy consumption of wastewater treatment plants is in the range of 0.52 kWh to 2.0 kWh/m 3.

Can solar energy be used for wastewater treatment?

Recent trends on wastewater treatment using solar energy were reviewed. Solar photocatalysis methods of wastewater treatment was studied and analysed. Advanced oxidation methods using solar energy are found to be effective. Technical limitations and environmental benefits are discussed.

Can solar power be used in wastewater treatment plants in China?

Self consumption of the PV power by the waste water treatment plant and solar radiation potential of the plant plays an effective role in deciding the economic viability of this initiative. The feed-in-tariff of the electricity generated by PV modules in wastewater treatment plants in China ranges between 0.034 and 0.063 USD/kWh [ 55 ].
