It is a power generation approach that is pollution free, renewable, flexible, storable, and so forth, serving as one of the multiple methods of utilising solar energy. Road lighting and residential construction have both put photovoltaic power generation to practical use. A solar power generation system can also be applied to the industry of water treatment due to its unique characteristics. The solar photovoltaic system consists of a solar charger, a solar battery, and a battery.
Water treatment facilities can benefit from the use of solar electricity generation systems because:
No sheltering of tall buildings around
Most of the water treatment plants are located in industrial areas with relatively extensive industrialisation as well as in remote locations. There are largely low-rise buildings around the water treatment plant, and the photovoltaic power generation system has a smaller shielding effect. As a result, the water treatment plant was built in a manner that the building itself and the structure were not easily occluded due to the low height and sparse layout, thus providing better lighting conditions.
Rather big installable roof area
Basically any water treatment plant must have rather large structures, such as biological reaction tanks, secondary sedimentation tanks, blower rooms, etc. This usually features also a large area for mounting photovoltaic systems. The photovoltaic power generation facility at the water treatment plant mainly uses distributed photovoltaic systems that can be installed on roofs, thus there is no new land acquisition, no change in land use, no impact on cultural relic protection, no increased building area, and no changes to buildings.
Improve the technological treatment effect
Water treatment plant's photovoltaic system can reduce water evaporation, increase water cleaning capability, and reduce environmental impact of sewage evaporation by implementing an efficient layout and design. In addition, it can still reduce the speed of the wind over the pool, improve the local small environment, increase the temperature of the pool water, enhance the growth activity of the microorganisms, and ultimately improve the sewage treatment efficacy, thereby improving the overall economic value of the project.
High and stable power generation of the water treatment plant
As well as high-power components like blowers and submersible pumps, water treatment plants are used to handle relatively low-power components such as gates, grilles, and submersible flowers with a higher computing power. Additionally, the relatively balanced water volume makes the equipment operation and load characteristics relatively stable, which facilitates the design of a solar photovoltaic power plant.
Since the plant's electrical consumption is high and its changes are small, taking the solar system into account can derive its maximum power, reduce power loss from the solar inverter, and reduce the light rejection rate.
Good financing conditions
These plants typically have long operating cycles, guaranteed operation, stable benefits, and high self-sufficiency ratios, so financing problems are not an issue.
Low maintenance cost
Solar photovoltaic system operating costs are primarily related to water and maintenance, with the exception of equipment damage caused by force majeure. It is possible for sewage treatment plants to leave effluent and recycled water clean.
Meet the PV module's cleaning requirements. Water that has been cleaned can also be collected and directly sent to the wastewater treatment process, thus saving water as well as reducing maintenance costs.
