Thus, self-sustaining wastewater treatment can be realized by PV-bio hybrid and CSP-bio hybrid power generation in Phoenix, and PV-bio hybrid power generation in Lansing. However, since
The application of solar photovoltaic in wastewater treatment mainly includes two aspects: (a) the pollutant can be removed and recovered through photovoltaic power generation electrolysis; and (b) the solar photovoltaic can provide electricity for sewage biological treatment through photovoltaic power generation [ 32 ].
A targeted perspective for photovoltaic wastewater treatment was provided. Three typical photovoltaic wastewater treatment technologies were described. Chemical precipitation is preferred for treating fluorine-rich wastewater. Biological method is the main treatment process of nitrogen-rich wastewater.
Solar-powered wastewater treatment can vary from simpler one (solar still and SODIS) to mature technology (MD, MSF and RO). Selection of these technologies is very site specific. Solar still and SODIS are suitable for tropical countries having abundant solar energy but lacking investment and skilled manpower.
The combination of photovoltaic power generation and wastewater treatment, and the implementation of contract energy management can further reduce the cost of wastewater treatment.
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).
The PV-RO system is technically feasible but expensive. Upgradation of these technologies could give new market opportunities in the modern era. This paper presents the comprehensive review on the advances and challenges in solar-powered wastewater treatment technologies.
