Solar products wastewater
Photovoltaic wastewater mainly comes from the waste additive liquid and cleaning wastewater generated in the process of silicon rod cutting, grinding and slicing, as well as silicon wafer grinding, etching and polishing. Its treatment difficulties mainly include: high concentration of organic matter (mainly polyethylene glycol, etc.), suspended solids (mainly silicon powder and silicon carbide), as well as fluoride ions, acids and bases (mainly hydrofluoric acid, nitric acid and other buffer acids) and other pollutants

Glass process wastewater
The main polluting components of glass processing wastewater are "coolants" and saw blade cooling water. Typically, the main components of coolants are resin acids and their saponification products, unsaturated fatty acids and their saponification products, and lignin and its degradation products. Resin acids are mainly rosin acid and hippuric acid.

Industrial ceramics process wastewater
Ceramic processing wastewater is clay, feldspar, limestone and other raw materials filled with the appropriate dispersant and moisture moulding berkelium firing into ceramics in the production process of wastewater discharged. Wastewater mainly from before and after the moulding process, wastewater containing solid waste concentration of 0.1-0.2% (by weight), PH7.5-8.5, generally by the natural sedimentation pond precipitation treatment and discharge. After discharge, blockage of drainage pipes and siltation of the river should be prevented.

Plastics recycling wastewater
Recycled plastics recycling is the production of new or discarded plastics that have been used through a dowel rod machine, and then cut into pellets by a granulator. Plastic recycling process mainly produces plastic cleaning, separation and wet crushing process.
