1. How do I choose the right Poly Aluminium Chloride (PAC) grade?
Poly Aluminium Chloride (PAC) grades can differ in Al₂O₃ content, basicity, water-insoluble matter, appearance, and particle characteristics. The right grade depends on the raw water quality, treatment process, dosage system, and application. For industrial and wastewater treatment, buyers should select PAC based on actual water conditions rather than relying on aluminium content alone.
2. How does PAC improve the water treatment process?
Poly Aluminium Chloride (PAC) works by neutralizing the electrical charges of suspended and colloidal particles, allowing them to aggregate into larger flocs. These flocs can then be separated through sedimentation, filtration, or flotation. Its efficient coagulation performance can help improve water clarity and support stable downstream treatment processes.
3. What should B2B buyers consider when importing PAC?
When purchasing Poly Aluminium Chloride in bulk, B2B buyers should evaluate product consistency, Al₂O₃ content, basicity, packaging, loading capacity, production capability, and export experience. Reliable documentation such as COA and SDS, together with stable delivery schedules, is also important for long-term international supply.
