Polyaluminum chloride (PAC) stands out as an exceptionally efficient inorganic polymer flocculant, renowned for its superior coagulation and sedimentation prowess. This breakthrough product is a game-changer in industrial wastewater treatment, offering a masterful enhancement to water treatment processes, especially within paper mills. Celebrated for its unparalleled purity, minimal impurities, quick-flocculating action, and exemplary sedimentation properties, it effectively eradicates suspended solids (SS), COD, chromaticity, and certain heavy metals from paper wastewater. This not only elevates water quality compliance but also dramatically slashes treatment costs.
Product Features
a. Outstanding Flocculation and Sedimentation Performance
Rapid Flocculation: This product rapidly generates dense alum clusters in water, achieving a settling pace 30%~50% swifter than conventional aluminum salts like aluminum sulfate, thereby significantly trimming down treatment time.
Efficient Turbidity Removal: With an exceptional removal efficiency of colloidal particles and suspended solids (SS) exceeding 95%, it ensures effluent turbidity is brought down to under 5NTU.
Wide pH Adaptability: Exhibits outstanding performance across a pH range of 5-9, obviating the need for frequent pH adjustments, thus streamlining operational tasks.
b. Significant Environmental and Economic Advantages
Low Residue Characteristics: The high-purity composition (Al2O3 ≥ 28%) slashes sludge volume by 20%~30%, considerably cutting down on sludge disposal costs.
Medication Usage Savings: Delivering equivalent results with just 1/2 to 1/3 the amount of aluminum sulfate, this product can reduce long-term expenses by over 30%.
No Secondary Pollution: With heavy metal content, including lead, significantly lower than national standard limits, it guarantees enhanced safety of treated wastewater.
c. Robust Adaptability to Water Quality
Low Temperature Resistance: Maintains strong flocculation even in low temperature conditions under 5 ºC, effectively 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 in ore washing and construction mud water.
Synergistic Effect Enhancement: When combined with polyacrylamide (PAM), it boosts floc strength and improves dewatering performance, making it ideal for deep sludge dewatering applications.
d. Industry-Specific Optimization
Paper-Specific Formula: Finely optimized for small fibers, lignin, and other papermaking wastewater components, enhancing decolorization rates to over 80%.
Heavy Metal Capture Function: Efficiently removes heavy metal ions such as lead and chromium through hydroxyl bridging, boasting a removal rate above 90%.
Demulsification and Oil Removal Ability: Capable of demulsifying and separating emulsified oil in oily wastewater, like that from mechanical processing.
