London sewage treatment plant uses photovoltaic folding containers for fast charging

Can a small PV wastewater treatment plant reduce energy consumption?

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.

Can EC technology be used for primary treatment of PV wastewater?

Both EC technology and chemical precipitation have high fluoride removal efficiency, and can be used for primary treatment of PV wastewater. However, when used alone, the effluent fluoride concentration is difficult to meet the standard.

Can a small PV wastewater treatment plant use Packed towers?

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. Moreover, fouling on the surface of packed towers is a fatal problem .

How is PV cell production wastewater treated?

In conclusion, current research on PV cell production wastewater remains in its exploratory stage. For fluorine-rich PV wastewater, the combination of chemical precipitation and coagulation sedimentation processes is still the predominant approach. However, more research efforts are needed in CaF 2 resource recovery.
