Application example: "Wastewater treatment in the manufacturing process of solar cell wafers."
We propose high-durability plastic valves and sealing materials.
The wastewater treatment process for solar cell wafer manufacturing involves the treatment of wastewater containing various components generated from the processing of used slurry. The wastewater mainly contains oils, acids, alkalis, and heavy metals, and may also contain a significant amount of solids. To dispose of such wastewater in accordance with legal regulations or to discharge it into the sewage system, appropriate pretreatment is necessary. By filtering and neutralizing the raw water and then passing it through a reverse osmosis system, it can be discharged into the sewage system.
