Solar Photovoltaic Industry

Photovoltaic wastewater mainly comes from auxiliary and cleaning wastewater that generated from the process of cutting, grinding, slicing of silicon rod, and the process of grinding, corrosion, polishing of silicon wafer. The difficulties of photovoltaic treatment are: the concentration of organics (mainly polyethylene glycol) and suspended solids (mainly Microsilica, SiC) is high, and it also contains contaminants such as Fluorine ions, acid and alkali (mainly hydrofluoric acid, nitric acid and other buffer acids). If photovoltaic wastewater cannot be treated properly, the environment will be polluted easily.
