Polyaluminum chloride (PAC) is a groundbreaking inorganic polymer flocculant renowned for its extraordinary prowess in coagulation and sedimentation. This avant-garde product revolutionizes industrial wastewater treatment by delivering a remarkable enhancement to water purification processes, especially within the paper manufacturing industry. It stands out for its unmatched purity and minimal impurities, offering rapid flocculation and exceptional sedimentation abilities. PAC excels in removing suspended solids (SS), COD, chromaticity, and specific heavy metals from paper mill wastewater, elevating water quality compliance to unprecedented levels while significantly reducing treatment costs.
Product Features
a. Outstanding Flocculation and Sedimentation Performance
Rapid Flocculation: This cutting-edge product swiftly forms compact alum clusters in water, achieving a sedimentation speed 30%~50% faster than traditional aluminum salts like aluminum sulfate. This remarkable efficiency translates into a substantial reduction in treatment time, enhancing operational productivity.
Efficient Turbidity Removal: With an impressive efficiency exceeding 95% in eliminating colloidal particles and suspended solids (SS), it ensures effluent turbidity is reduced to below 5NTU, maintaining pristine water clarity.
Wide pH Adaptability: Exhibits outstanding performance across a pH spectrum of 5-9, dispensing with the need for frequent pH adjustments and thereby simplifying operational procedures.
b. Significant Environmental and Economic Advantages
Low Residue Characteristics: The high-purity nature (Al2O3 ≥ 28%) minimizes sludge volume by 20%~30%, greatly reducing sludge disposal costs and enhancing economic efficiency.
Medication Usage Savings: Achieving equivalent results with merely 1/2 to 1/3 the dosage compared to aluminum sulfate, this product can drive down long-term expenses by over 30%, offering substantial savings.
No Secondary Pollution: Featuring heavy metal content, including lead, significantly below national standard limits, it ensures the safety and cleanliness of the treated wastewater, mitigating environmental impacts.
c. Robust Adaptability to Water Quality
Low Temperature Resistance: Ensures effective flocculation even at temperatures as low as 5 ºC, efficiently tackling the challenge of reduced sewage treatment efficiency during colder months.
High Turbidity Tolerance: Expertly handles high turbidity wastewater with SS levels reaching up to 5000mg/L, such as those from ore washing and construction mud water, guaranteeing consistent performance.
Synergistic Effect Enhancement: When paired with polyacrylamide (PAM), it enhances floc strength and optimizes dewatering, making it ideal for deep sludge dewatering applications.
d. Industry-Specific Optimization
Paper-Specific Formula: Meticulously optimized for small fibers, lignin, and other papermaking wastewater components, it boosts decolorization rates to over 80%, ensuring superior water clarity.
Heavy Metal Capture Function: Effectively eradicates heavy metal ions such as lead and chromium through hydroxyl bridging, achieving a removal rate exceeding 90%.
Demulsification and Oil Removal Ability: Efficiently demulsifies and separates emulsified oil in oily wastewater, like that from mechanical processing, ensuring cleaner effluents and improved environmental protection.
