Product Description:
 

Poly-Aluminum Chloride (PAC) is a highly effective coagulant used in the purification of drinking water, wastewater treatment, and various industrial processes. It is a polymeric compound with aluminum ions that are cross-linked by hydroxyl groups, resulting in a high molecular weight compound with superior coagulation properties.
 

Key Features:

• High Coagulation Efficiency: PAC provides rapid and efficient flocculation, effectively removing suspended solids, organic matter, and other contaminants from water.
• Versatility: Suitable for a wide range of water treatment applications, including surface water, groundwater, and various industrial effluents.
• Environmental Compatibility: Forms a gelatinous precipitate that can be easily separated from water, reducing the volume of sludge and facilitating disposal.
• Adjustable Properties: The basicity and degree of polymerization can be adjusted during production to tailor the product for specific applications.

Applications:

• Water Treatment: Used for the purification of drinking water by removing turbidity, color, and organic compounds.
• Wastewater Treatment: Effective in the treatment of industrial and municipal wastewater to meet discharge standards.
• Industrial Processes: Utilized in various industries such as papermaking, textile, and food processing for water clarification and purification.

Safety Information:

• Handle PAC with appropriate personal protective equipment (PPE), including gloves, safety goggles, and a mask.
• Avoid inhalation of dust and contact with skin and eyes. In case of contact, flush immediately with plenty of water and seek medical advice if necessary.

Storage Conditions:

• Store in a cool, dry, and well-ventilated area away from direct sunlight and heat sources.
• Keep containers tightly sealed to maintain product integrity and prevent moisture absorption.
