Polyaluminum chloride (PAC) is a groundbreaking inorganic polymer flocculant, renowned for its unparalleled efficiency in coagulation and sedimentation processes. This revolutionary solution redefines industrial wastewater treatment, significantly elevating water purification methods, especially within the paper manufacturing industry. With its superior purity and minimal impurities, PAC delivers rapid flocculation and exceptional sedimentation prowess. It effectively eliminates suspended solids (SS), COD, chromaticity, and specific heavy metals from paper mill effluents. This not only ensures compliance with water quality standards but also dramatically curtails treatment costs.
Product Features
a. Unmatched Flocculation and Sedimentation Performance
Rapid Flocculation: This state-of-the-art product swiftly forms dense alum clusters, achieving a sedimentation rate 30%~50% faster than conventional aluminum salts such as aluminum sulfate. This results in a substantial decrease in treatment duration.
Efficient Turbidity Removal: Demonstrating a remarkable efficiency of over 95% in eliminating colloidal particles and suspended solids (SS), it reduces effluent turbidity to below 5NTU, thus ensuring pristine water clarity.
Wide pH Adaptability: Exhibits stellar performance across a broad pH range of 5-9, eliminating the frequent need for pH adjustments and thereby streamlining operational activities.
b. Exceptional Environmental and Economic Benefits
Low Residue Characteristics: The high-purity composition (Al2O3 ≥ 28%) reduces sludge volume by 20%~30%, significantly cutting sludge disposal costs and boosting economic efficiency.
Medication Usage Savings: Achieving similar results with just 1/2 to 1/3 the dosage compared to aluminum sulfate, this product can reduce long-term costs by over 30%.
No Secondary Pollution: With heavy metal content, including lead, well below national standard limits, it assures the treated wastewater remains safe and clean.
c. Superior Adaptability to Water Quality
Low Temperature Resistance: Maintains effective flocculation even at temperatures as low as 5 ºC, efficiently addressing the challenge of decreased sewage treatment efficiency during colder months.
High Turbidity Tolerance: Expertly handles high turbidity wastewater with SS levels up to 5000mg/L, such as those from ore washing and construction mud water, ensuring consistent performance.
Synergistic Effect Enhancement: When combined 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: Carefully optimized for small fibers, lignin, and other papermaking wastewater elements, it enhances decolorization rates to over 80%, ensuring superior water clarity.
Heavy Metal Capture Function: Efficiently removes heavy metal ions like lead and chromium through hydroxyl bridging, achieving a removal rate exceeding 90%.
Demulsification and Oil Removal Ability: Effectively demulsifies and separates emulsified oils in oily wastewater, such as that from mechanical processing, ensuring cleaner effluents.
