Technical details and manufacturing context for Industrial Grade Polyaluminum Chloride Coagulant

Definition
Polyaluminum chloride (PAC) is an inorganic polymer coagulant manufactured through controlled hydrolysis of aluminum salts. It serves as a critical raw material in industrial water treatment processes, providing superior flocculation performance compared to traditional aluminum sulfate. This chemical product is essential in B2B supply chains for wastewater treatment plants, paper mills, and mining operations, where it removes suspended solids, organic matter, and phosphates. Its high efficiency reduces sludge volume and operational costs across multiple industrial sectors.
Working Principle
Hydrolyzes in water to form positively charged aluminum hydroxide polymers that neutralize negatively charged colloidal particles, causing aggregation and sedimentation.

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Corrosion-induced degradation
Cause: Polyaluminum chloride's acidic nature (pH typically 2-3) can corrode storage tanks, piping, and dosing equipment made from incompatible materials like carbon steel or certain plastics, leading to leaks, contamination, and structural failure.
Crystallization and clogging
Cause: Improper storage conditions (e.g., freezing temperatures or excessive heat) or prolonged stagnation can cause the coagulant to crystallize or form solid deposits, blocking valves, pumps, and injection points, disrupting dosing accuracy and flow.
Maintenance Indicators
  • Visible corrosion, pitting, or leaks around storage tanks, pumps, or pipe joints, especially at welds or connections.
  • Audible pump cavitation or motor strain, or visual flowmeter irregularities indicating reduced/erratic dosing due to partial blockages or viscosity changes.
Engineering Tips
  • Use corrosion-resistant materials (e.g., HDPE, PVC, stainless steel 316L, or fiberglass) for all contact surfaces, and implement routine thickness testing and pH monitoring of stored product to detect early corrosion.
  • Maintain storage temperatures between 5-40°C, ensure regular agitation or recirculation to prevent settling/crystallization, and install inline filters with scheduled cleaning to avoid clogging in dosing systems.
