Polyaluminum chloride (PAC) is an efficient inorganic polymer flocculant with excellent coagulation and sedimentation properties, widely used in industrial wastewater treatment. This product is specifically designed for optimizing water treatment in paper mills. It has the characteristics of high purity, low impurities, fast flocculation, and good sedimentation. It can effectively remove suspended solids (SS), COD, chromaticity, and some heavy metals from paper wastewater, improve water quality compliance rate, and reduce treatment costs.
Product Features
a.Excellent flocculation and sedimentation performance
Rapid flocculation: It can quickly form dense alum flowers in water, with a settling rate 30%~50% faster than traditional aluminum salts (such as aluminum sulfate), greatly reducing treatment time.
Efficient turbidity removal: The removal rate of colloidal particles and suspended solids (SS) is over 95%, and the effluent turbidity can be reduced to below 5NTU.
Wide pH adaptability: It can maintain excellent performance within the pH range of 5-9, without the need for frequent pH adjustment, reducing operational difficulty.
b.Significant environmental and economic advantages
Low residue characteristics: The high-purity formula (Al2O3 ≥ 28%) reduces sludge volume by 20%~30% and lowers sludge disposal costs.
Saving medication usage: Under the same effect, the dosage is only 1/2 to 1/3 of aluminum sulfate, and long-term use can save more than 30% of the overall cost.
No secondary pollution: The content of heavy metals (lead, etc.) is much lower than the national standard limit, and the safety of the treated wastewater is higher.
c.Strong adaptability to water quality
Low temperature resistance: It can maintain good flocculation effect in low temperature environments below 5 ºC, solving the problem of decreased sewage treatment efficiency in winter.
High turbidity tolerance: It can treat high turbidity wastewater with SS up to 5000mg/L (such as ore washing, construction mud water, etc.).
Synergistic effect enhancement: When combined with polyacrylamide (PAM), it can improve floc strength and dewatering performance, especially suitable for deep sludge dewatering.
d.Industry specific optimization
Paper specific formula: Optimized for small fibers, lignin and other components in papermaking wastewater, with a decolorization rate increased to over 80%.
Heavy metal capture function: Efficiently remove heavy metal ions such as lead and chromium through hydroxyl bridging (removal rate>90%).
Demulsification and oil removal ability: It has the ability to demulsify and separate emulsified oil in oily wastewater (such as mechanical processing wastewater).
