We intalled our deep fluoride removal system for one solar wafer/solar cells factory
In early May, the photovoltaic industry took an important step in advancing sustainable practices. A domestic solar wafer and solar cell factory has successfully installed the most advanced deep fluoride removal system. This installation marks important progress in meeting the growing demand for efficient photovoltaic wastewater treatment.
The rapid expansion of the photovoltaic industry has led to an increase in the production of photovoltaic wastewater, which requires the implementation of advanced treatment processes. Treatment of this wastewater is critical to ensure it meets environmental standards before discharge.
Photovoltaic wastewater mainly contains pollutants such as silicon powder, silicon carbide, polyethylene glycol, fluoride ions, acids and bases. When silicon rods and wafers are sliced, ground, cut off, ground, corroded, and polished, additive waste liquid and Clean waste water. Polysilicon wastewater, organic silicon wastewater, silicon wafer cleaning, mortar recycling wastewater, cutting and polishing wastewater are also collectively referred to as photovoltaic wastewater.The existence of these photovoltaic wastewater will cause ecological pollution of the environment, and will also restrict the sustainable development of this type of industry. So how should this type of photovoltaic wastewater contain fluoride wastewater be treated?
The advanced treatment process of photovoltaic wastewater fluorine generally includes three stages: pretreatment, main treatment and post-treatment. The pretreatment stage is mainly to remove suspended solids and impurities in the wastewater to provide good water quality conditions for the main treatment stage; the main treatment stage is to perform operations such as adsorption, exchange or membrane separation of fluoride ions; the post-treatment stage is mainly to treat the treated wastewater. Wastewater is disinfected, desalinated and other operations are carried out to meet the requirements for discharge or reuse.
The implementation of this advanced treatment system highlights the industry's commitment to environmental stewardship and sustainability. It represents a proactive approach to addressing the environmental challenges associated with the rapid growth of the photovoltaic industry.
As demand for solar energy continues to grow, installing innovative wastewater treatment technologies is critical to minimizing the industry’s ecological footprint. The successful deployment of the deep fluoride removal system has set a precedent for responsible environmental protection practices in the photovoltaic industry and has become a model for sustainable development in the renewable energy field.
