Against the backdrop of stricter global environmental policies and industrial technology upgrades, PAC (polyaluminium chloride and polyanionic cellulose), as two core chemicals, is driving green transformation in water treatment, oil extraction and other fields with its high efficiency and environmental protection properties. The following is a multi-dimensional analysis of the innovative value of PAC products from the perspectives of technical characteristics, application scenarios and market trends.

• Polyaluminium chloride (PAC): the “green guard” in the field of water treatment

PAC comes in white, yellow, brown, etc. due to different production processes. White PAC has the highest purity and is used for food-grade water treatment; yellow is suitable for drinking water; and brown is for high-turbidity wastewater (such as sand washing wastewater).Compared with traditional coagulants (such as aluminum sulfate), the dosage of PAC is reduced by 30%-40%, and it is suitable for a wide pH range (5-9), with a fast flocculation speed and significant sedimentation effect.

• Polyanionic cellulose (PAC): the "performance engine" of oil extraction

As a water-soluble high molecular polymer, polyanionic cellulose (PAC) plays a key role in thickening, suspension, and filtration control in oil drilling fluids, facilitating efficient and safe mining.

Core Features:

1. Viscosity enhancement and rheology control: PAC-HV (high viscosity) and PAC-LV (low viscosity) can adjust the viscosity of drilling fluid, improve the cuttings carrying capacity, and reduce the risk of wellbore collapse.

2. High temperature and high salt stability: It can still maintain low filtration loss at temperatures above 150°C or in high-salt environments, ensuring operational safety under extreme geological conditions.

From purifying every drop of water to supporting 10,000-meter deep well operations, PAC products are reshaping the future of industry with technological innovation and environmental protection concepts. With the continued investment of leading companies such as Dongzheng Chemical and Songyang Water Purification, PAC will unleash its potential in more areas and inject "chemical power" into global sustainable development.
