Wastewater treatment is an energy-intensive process. The power consumed by a wastewater treatment plant (WWTP) ranges from 1.2 to 5.2 kWh/kg TOD (Luo et al., 2019), while the cost of the electricity consumed by it generally accounts for 50 %–70 % of its total operating cost depending on the scale of its design, the treatment process, and requirements
To do that, simple and pragmatic models interconnected to each other allow to manage the energy coming from photovoltaic (PV) panels in order to exploit the total solar power generated and to reach the maximum remediation during the treatment of a polluted wastewater. To increase and improve the use of energy, a vanadium redox flow battery was used as
Photovoltaic enterprises usually deal with the wastewater in the factory, and then discharge it to the municipal pipes. The wastewater treatments are also different due to the different processes of crystalline silicon solar panels, and they can

Presently, India is in the stage of installation of solar photovoltaic panels and no focus is being given towards the impending problem of handling solar waste. The absence of adequate regulations, guidelines and operational infrastructure for photovoltaic waste in the country may lead to waste being inappropriately landfilled or incinerated in a manner that may

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. The removal method and sequence of pollutants in mixed wastewater need attention.
However, the energy consumption increases if the influences mentioned above are improved. The process is generally treated using packed towers . To obtain a high removal rate, it is necessary to enlarge the size of the equipment or increase the number of equipment . So, it is not applicable to small PV wastewater treatment plants.
Summary of actual PV wastewater treatment cases and methods (Note: TN in this table is mainly composed of NH 4+ -N and NO 3− -N; Comprehensive wastewater* refers to the mixed wastewater rich in fluoride and nitrate; Comprehensive wastewater** refers to the mixed wastewater of the three.).
However, when enterprises choose treatment technologies for fluorine-rich, ammonia-rich and nitrate-rich PV wastewater, the economic benefits also need to be taken into account, including investment costs, operating costs, treatment efficiency, energy consumption, maintenance difficulty and environmental friendliness.
If low-cost environmentally friendly catalysts can be found, the application of photocatalysis technology in PV wastewater could be promising. In short, of all the above methods, biological treatment is the most economically feasible and the primary choice for treating ammonia-rich and nitrate-rich wastewater.
However, the biodegradability of PV wastewater is poor, necessitating the addition of carbon sources or improvements in biodegradability through hydrolysis and acidification. At the same time, this method cannot realize the ammonia recovery.
