Technical FAQs 4

Are wastewater treatment plants using solar energy?

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.

Are solar photocatalytic wastewater treatment plants environmentally friendly?

Their do exist very few medium scale solar photocatalytic wastewater treatment plants which are environment friendly compared to the existing conventional systems. Treatment of wastewater using solar energy reduces the use of conventional power there by reduces emission of GHG.

How much energy does a wastewater treatment plant use?

The study conducted by (Guernanou, 2019) evaluated an energy consumption of 0.6 kWh/m 3 which emitted 185.61 g of equivalent CO 2 /kWh for wastewater treatment. The direct and indirect ways of GHG emission from a WWT are highlight in Table 2.

Can wastewater treatment plants reduce energy use?

Intro: The more we can reduce energy use at wastewater treatment plants, which are big users, the more of an environmental impact there is. But also from a financial perspective, for the municipalities that own and operate these plants, this could be a big money saver.
