FAQ
What is poly aluminium ferric chloride?
poly aluminium ferric chloride is a water treatment chemical used for coagulation, flocculation, or adsorption in wastewater and drinking water treatment. It effectively removes suspended solids, colloidal particles, and dissolved organic compounds through physicochemical processes.
How does poly aluminium ferric chloride work in water treatment?
poly aluminium ferric chloride works by destabilizing colloidal particles through charge neutralization, forming flocs through bridging and sweep coagulation, and facilitating removal through sedimentation or flotation. The mechanism depends on the specific chemical type and water quality conditions.
What dosage of poly aluminium ferric chloride should I use?
Typical dosage: 20-80 mg/L for drinking water, 50-300 mg/L for industrial wastewater, 0.5-5 mg/L for PAM. Actual dosage must be determined by jar testing. Contact HydroChemix for free technical guidance.
How to choose the right grade of poly aluminium ferric chloride?
Selection depends on water pH, turbidity, COD level, industry, and discharge standards. Use our Chemical Selection Tool or request a free sample for jar testing.
