Jiangsu Lanyao Water Treatment Co., Ltd., a pioneer in China’s water treatment industry since its establishment in 1996, has consistently focused on technological innovation. Recently, the company highlighted the exceptional performance of its flagship product, Poly Aluminum Ferric Chloride (PAFC), in wastewater treatment, offering an efficient and cost-effective solution for both industrial and municipal applications.
Technical Advantages of PAFC
-
High Flocculation Efficiency & Broad Adaptability
Combining the dual benefits of aluminum and iron salts, PAFC generates dense, rapidly settling flocs, making it particularly effective for treating high-turbidity and low-temperature water. Compared to traditional coagulants (e.g., alum or polyferric sulfate), PAFC accelerates sedimentation by over 30% without requiring additional alkaline additives. Its pH adaptability (5.0–9.0) ensures stable performance across diverse water conditions. -
Cost Savings & Economic Benefits
Optimized production processes enable PAFC to reduce dosage by 1/3 to 1/2 compared to conventional agents, lowering overall treatment costs by more than 40%. This advantage has made PAFC a preferred choice for industries such as chemicals and paper manufacturing. -
Eco-Friendly Performance
PAFC not only removes suspended solids and colloids but also strongly adsorbs phosphorus and heavy metals (e.g., copper, zinc, nickel), reducing eutrophication risks. Studies show its phosphorus removal rate exceeds 90%, with heavy metal removal surpassing 85%. Compliant with China’s GB15892-2003 standard, PAFC ensures minimal residual aluminum/iron content, guaranteeing effluent safety.
Case Studies & Industry Recognition
PAFC has been successfully deployed in multiple municipal and industrial projects. For instance, a chemical park reduced iron ion concentration in cooling water from 1.2 mg/L to below 0.1 mg/L after adopting PAFC, significantly improving water clarity. In a centralized procurement bid by a wastewater treatment plant in Yancheng, PAFC was selected as the primary coagulant due to its stability and ease of transportation.
Innovation & Sustainable Development
In collaboration with academic partners, Jiangsu Lanyao has pioneered a sludge-to-PAFC conversion technology. By catalyzing the hydrothermal hydrolysis of inorganic components in municipal sludge, the process transforms waste into PAFC, aligning with circular economy principles. This patented technology has been published in Environmental Engineering journal.
Future Outlook
“The tightening of environmental regulations and growing demand for water treatment will further unlock PAFC’s market potential,” stated the General Manager of Jiangsu Lanyao. “We plan to expand production capacity and develop tailored formulations for mining, textile dyeing, and other sectors to support global carbon neutrality goals.”
