product details

Core Features

• Convenient to Use: No need for dissolution, can be directly added, saving labor and dissolution equipment costs;

• Quick Response: Liquid molecules have high activity, and the flocculation speed is 20% faster than that of the solid version, making it particularly suitable for small water treatment facilities or emergency scenarios;

• Low Corrosivity: Wide pH adaptability (4-10), with lower corrosivity to pipelines/equipment than high-concentration aluminum salts.

Applicable Scenarios

Our PAC has been widely used in industrial and municipal water treatment scenarios worldwide, with typical cases including:

• Drinking water purification: Removal of iron and manganese from groundwater, turbidity removal from surface water, meeting international drinking water standards;

• Municipal sewage: Coagulation sedimentation, sludge dewatering, BOD (biochemical oxygen demand) in urban domestic sewage treatment plants;

• Industrial wastewater: Treatment of papermaking black liquor (delignification, reduction of COD), decolorization of printing and dyeing wastewater (removal of reactive dyes, sulfur dyes), removal of heavy metals from electroplating wastewater (Cr⁶⁺, Cu²⁺), and removal of phosphorus from chemical wastewater;

• Other scenarios: Coal slime water clarification in coal preparation plants, oil removal from oilfield reinjection water, and recycling of stone cutting wastewater.
