PAC Drinking Water Purification and Advanced Water Treatment

White Drinking Grade Polyaluminum Chloride (PAC) is a high-purity coagulant extensively used in potable water treatment. As an inorganic polymer, it consists of aluminum hydroxide and chloride ions, forming a highly efficient polymeric structure ([Al₂(OH)ₙCl₆₋ₙ]ₘ).

Distinguished from conventional PAC (which may appear yellow due to iron impurities), the white variant undergoes rigorous purification to eliminate contaminants, ensuring compliance with stringent drinking water safety standards. It outperforms traditional coagulants like alum by offering enhanced coagulation efficiency, lower sludge production, and reduced aluminum residuals, making it ideal for applications requiring high water quality.

Features:

High Purity & Safety: Contains minimal heavy metals (e.g., iron, manganese) and meets certifications such as NSF/ANSI 60, ensuring suitability for human consumption.

Effective Coagulation: Works across a broad pH range (5–9) and performs well even in low-temperature conditions, forming dense, rapidly settling flocs.

Low Dosage Requirement: Achieves superior turbidity removal with 30–50% less dosage compared to traditional coagulants, reducing operational costs.

Stability & Handling: Non-corrosive, soluble in water, and stable during storage, with a long shelf life.

Environmental Benefits: Generates less sludge due to lower aluminum content, minimizing disposal challenges and environmental impact.

pH Neutrality: Minimizes pH fluctuations in treated water, reducing the need for post-treatment adjustments.

Applications:

Municipal water supply systems.

Bottled water production and breweries.

Rural and urban potable water purification.

Process water treatment for breweries, dairy, and soft drink manufacturing.

Ensures compliance with hygiene standards in food processing.

Production of ultra-pure water for drug formulation and medical equipment sterilization.

Paper manufacturing (retention aid and wastewater clarity).

Textile dyeing (removal of colloidal impurities).

Oil refinery wastewater treatment.

Secondary clarification to maintain water clarity and hygiene.
