PAC Flocculant PAC Powder Poly Aluminum Chloride

for Waste Water Treatment

Product Overview

LANSEN PAC is a spray-dried polyaluminum chloride (PAC) in pale yellow powder form, manufactured from high-purity aluminum hydroxide [Al(OH)₃] under food-grade standards. As a primary inorganic coagulant based on trivalent aluminum ions (Al³⁺), it is NSF/ANSI Standard 60 certified for drinking water treatment, while also serving as a retention aid in papermaking and a flocculant for wastewater/swimming pool purification.

Technical Advantages

1. Advanced Coagulation Mechanism

   • Combines hydroxyl bridging and polyanionic polymerization to form highly charged inorganic macromolecules, achieving superior coagulation efficiency compared to conventional alum or ferric salts.

   • Generates larger, denser flocs for rapid sedimentation and reduced sludge volume.

   • 
     

2. Broad Operational Adaptability

   • Effective across pH 4.0-9.0, eliminating the need for pH adjustment in most scenarios.

   • Exceptional performance in challenging conditions:

     • Algae-laden surface water

     • Low-temperature (<5°C), low-turbidity (<10 NTU) raw water

     • Mildly contaminated water (COD <100 mg/L)

   • Enhanced turbidity removal for high-turbidity water (>1000 NTU).

   • 
     

3. Industrial Efficiency

   • Dosage reduction by 30-50% versus traditional coagulants, lowering operational costs.

   • Minimal residual aluminum (<0.1 ppm), ensuring compliance with WHO drinking water guidelines.
