In the process of industrial production, fluoride-containing wastewater has become a kind of pollution source that cannot be ignored. This kind of wastewater mainly comes from aluminum electrolysis, steel, glass, semiconductor, pharmaceutical and other industries, and its significant characteristic is that it contains a high concentration of fluoride ions.
Efficient liquid fluoride remover is a water treatment agent specifically designed for the treatment of fluoride-containing wastewater, featuring rapid fluoride removal, ease of operation, and strong environmental friendliness. It excels in managing fluoride exceedances in various industrial wastewater, particularly playing a crucial role in advanced treatment processes. This agent ensures that the fluoride ion concentration in the effluent remains stable and meets standards, below 1 mg/L. It is suitable for groundwater, surface water, and industrial wastewater (such as from electroplating, coking, and lithium battery production), especially effective in treating high-concentration fluoride wastewater.
High efficiency liquid fluoride removal agent has shown broad application prospects in industry, municipal and drinking water treatment fields with outstanding characteristics such as high efficiency, low cost, simple operation and environmental friendliness. It has provided a reliable and effective solution for the treatment of fluoride-containing wastewater and has become the mainstream choice for the treatment of industrial fluoride-containing wastewater.
The high efficiency liquid fluoride removal agent technology is mature, convenient operation and low cost, no need for complex equipment or new treatment facilities, after adding, rapid sedimentation, low sludge amount and no increase of COD, TN and other pollutants, the cost performance is better than the traditional process, the adding process is as follows:
1. Direct addition: after dilution 10-20 times, metering pump injection, stirring reaction for 15 minutes, combined with PAM flocculation to realize solid-liquid separation.
2. pH adjustment: it is recommended to adjust the pH to 7-8 after adding to optimize the sedimentation effect.
3. Combined treatment: For high fluoride wastewater, calcium salt pretreatment (such as lime) can be combined to reduce the initial concentration, and then liquid fluoride removal agent can be used to treat it to 0.2mg/L or less.
