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
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.
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).
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.
Municipal/Industrial Sectors:
Potable water production
Paper mill retention systems
Textile/chemical wastewater treatment
Specialized Scenarios:
Swimming pool clarification
Stormwater remediation
Sludge dewatering water
