Specificities

The photovoltaic wastewater mainly comes from the cutting, grinding, and slicing of silicon rods, as well as the waste additive liquid and cleaning wastewater generated during the grinding, corrosion, and polishing processes of silicon wafers. The main difficulties in its treatment include: high concentration of organic matter (mainly polyethylene glycol, etc.), suspended solids (mainly silicon powder and silicon carbide), as well as pollutants such as fluoride ions, acid bases (mainly buffer acids such as hydrofluoric acid and nitric acid).
