Polyaluminum chloride (PAC) stands out as an exceptionally effective inorganic polymer flocculant, renowned for its remarkable coagulation and sedimentation prowess. A celebrated solution in the domain of industrial wastewater treatment, this cutting-edge product is meticulously engineered to elevate water treatment protocols, particularly within the exacting environment of paper mills. Distinguished by its unparalleled purity and minimal impurities, PAC delivers rapid flocculation and superior sedimentation attributes. It excels in the proficient elimination of suspended solids (SS), chemical oxygen demand (COD), chromaticity, and specific heavy metals from paper wastewater, not only ensuring water quality compliance but also significantly curtailing treatment expenses.
Product Features
a. Outstanding Flocculation and Sedimentation Performance
Rapid Flocculation: It quickly generates dense alum formations in water, achieving a settling rate 30%~50% faster than conventional aluminum salts, such as aluminum sulfate, thereby substantially cutting down on treatment time.
Efficient Turbidity Removal: With an impressive removal rate of colloidal particles and suspended solids (SS) exceeding 95%, the turbidity of the effluent is reduced to below 5 NTU.
Wide pH Adaptability: Demonstrates excellent performance across a pH range of 5-9, eliminating the need for frequent pH adjustments, thereby simplifying operational procedures.
b. Significant Environmental and Economic Advantages
Low Residue Characteristics: The high-purity formula (Al2O3 ≥ 28%) reduces sludge volume by 20%~30%, consequently decreasing sludge disposal costs.
Medication Usage Savings: Delivers comparable results with only 1/2 to 1/3 the dosage of aluminum sulfate, enabling long-term cost reductions exceeding 30%.
No Secondary Pollution: Heavy metal content, including lead and other elements, remains significantly below national standard limits, ensuring enhanced safety of treated wastewater.
c. Robust Adaptability to Water Quality
Low Temperature Resistance: Maintains robust flocculation effects even in low-temperature settings below 5 ºC, effectively tackling the challenge of reduced sewage treatment efficiency during winter months.
High Turbidity Tolerance: Efficiently handles high-turbidity wastewater with SS levels up to 5000 mg/L, such as that from ore washing and construction mud water.
Synergistic Effect Enhancement: When combined with polyacrylamide (PAM), it boosts floc strength and dewatering efficiency, making it ideal for intensive sludge dewatering applications.
d. Industry-Specific Optimization
Paper-Specific Formula: Carefully optimized for small fibers, lignin, and other elements in papermaking wastewater, with a decolorization rate soaring over 80%.
Heavy Metal Capture Function: Expertly removes heavy metal ions like lead and chromium through hydroxyl bridging, with a removal rate surpassing 90%.
Demulsification and Oil Removal Ability: Demonstrates exceptional capability to demulsify and separate emulsified oil in oily wastewater, such as that generated in mechanical processing.
