How can solar energy be integrated into water treatment processes?

Suitable technologies need to be developed to integrate solar energy into water treatment processes. Solar desalination technologies, solar photocatalysis technologies and solar disinfection are the most widely investigated solar based water treatment technologies, which will be discussed in detail in this paper.

What are the new solar water treatment technologies?

In this review, the new solar water treatment technologies, including solar water desalination in two direct and indirect methods, are comprehensively presented.

Is solar energy a good source of energy for water treatment?

Renewable energies like solar energy are widely explored as the primary source of energy in the water treatment process. Solar has been a clean and green energy solution and is available in abundance from the nature.

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.

What are the methods of wastewater treatment using solar energy?

Methods of wastewater treatment using solar energy 4.1. Photocatalysis method Photocatalysis is catalysis technology which is used to speed up light-relevant chemical reactions (Marquez et al., 2020).

Are solar based water treatment technologies a viable alternative to fossil fuels?

A comprehensive review of major solar based water treatment technologies is provided. The real world applicability as well as technical and economic feasibility of different technologies is evaluated. Water costs of current solar desalination technologies are still found to be high compared to fossil fuel based plants.
