2. Mechanism of PAC in Sludge Dewatering

अद्यतन्त्रं संविधानां प्रतिलेपं समायुक्तं सम्पूर्णं करोति-

1. पार्यत्र विस्थापिः PAC hydrolyzes in water to produce positively charged aluminum ions and polynuclear hydroxy-aluminum complexes, which effectively neutralize negative charges on sludge particles surfaces, reducing zeta potential and allowing particular aggregation in larger flocs.

2. Adsorption Bridging: As a polymer, PAC's molecular chains contain active groups that can adsorb multiple sludge particles, connecting fine particles into larger floc aggregates through "bridging" effects, accelerating sludge setting and thickening.

3. स्वतःSkeletonization: नवादा प्रश्नात्मकाः अङ्गीतानि नैवेद्यप्रतिष्ठापं प्रतिष्ठापं नैवे सामान्यप्रतिष्ठापं पार्यन्तां चिद्धान्तरम् "skeleton-like" जालस्थानं च प्रा This structure increases pore coordination numbers by 80%, raises effective porosity by two orders of magnitude, improves absolute permeability by 3.5–4.4 times, and reduces compressibility coefficient by 63%–69%. PAC conditioning can reduce sludge cake moisture content to 63.92%.

Research also shows that 8% PAC pretreatment combined with dialysis dehydration can reduce residual moisture content to 36.2%, with sludge porosity reaching as low as 0.29.

3. Sludge Dewatering इत्यस्य PAC इत्यस्य कोणः सम्पूर्णं च

1. निमानं Impact on Effluent pH: Compared to traditional aluminum salts (such as aluminum sulfate), PAC hydrolysis is milder and does not cause significant pH reduction in the effluent.

2. Low Dosage and Low Sludge Production: PAC has high active ingredient content, requiring relatively low dosage while producing less chemical sludge, reducing subsequent disposal costs.

3. High Turbidity Removal Efficiency: PAC exhibits excellent coagulation performance, effectively removing suspended solids and colloidal substances, improving supernatant quality.

4. High Floc Strength and Pressure Resistance: PAC forms dense, high-strength flocs particularly suitable for high-pressure dewatering equipment such as vacuum filters and plate-and-frame filter presses.

5. Wide pH Application Range: PAC maintains good coagulation performance across a broad pH range, with optimal performance at pH 5–7.

6. Compatibility with Other Chemicals: PAC can be used in combination with organic polymer flocculants such as polyacrylamide (PAM) for synergistic effects.
