Poly Aluminium Chloride for Drinking Water

Poly Aluminium Chloride (PAC) is an inorganic high-molecular compound that can be used for drinking water purification. Compared with traditional coagulants such as alum and iron salts, PAC has excellent flocculation efficiency and low residual aluminum content.

There are four models of PAC, in which PAC-D and PAC-M have excellent performance in drinking water treatment. Poly Aluminium Chloride for drinking water we provide is produced with advanced technology and high-purity raw materials, meeting international drinking water standards. It is suitable for urban water treatment plants, rural water supply systems, emergency drinking water purification and other fields.

Application

Poly Aluminium Chloride plays an important role in drinking water treatment, including:

Municipal tap water treatment
Rural and remote drinking water systems
Industrial water supply pre-treatment
Emergency and disaster-relief water purification

Feature

Poly Aluminium Chloride can be used for drinking water treatment with the following features:

Obvious water purification effect
Fast flocculation and sedimentation speed
No need to add alkaline additives
Adapt to a wide range of pH value
Low corrosiveness to pipeline equipment
Effectively remove COD, BOD and heavy metal ions from water

Usage

Our solid Poly Aluminium Chloride products for drinking water need to be dissolved and diluted before adding. According to different water quality, users can determine the best dosage through the test to adjust the concentration of the chemical.

Storage and Safety

Poly Aluminium Chloride for drinking water should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and moisture.
Keep bags tightly sealed to prevent caking or contamination.
Do not store near incompatible chemicals such as strong alkalis.
During transportation, PAC should be handled carefully to avoid package damage and environmental exposure.
It is non-flammable, but protective equipment is recommended during handling to avoid skin or eye irritation.
Shelf life is 12–24 months under proper storage conditions.

FAQ

Q: Is Poly Aluminium Chloride safe for drinking water?

A: Yes, drinking water grade PAC is safe.

Q: Can PAC replace alum completely?

A: Yes. PAC works better than alum in most cases and at lower dosages.

Q: Does PAC affect water pH?

A: Minimal impact compared to alum.

Q: How is PAC different from ACH?

A: ACH has higher purity for ultra-clear water. PAC is more cost-effective for general drinking water.

Q: Does PAC leave aluminum residue?

A: Very little. Residual aluminum is usually well within safety limits.

Q: How to store PAC?

A: Keep in a dry, cool place, sealed from moisture.

Q: What's the shelf life of PAC?

A: 12 to 24 months if stored properly.

Q: Can PAC be used in RO systems?

A: Yes, it's suitable for pretreatment before reverse osmosis.

Q: Is your PAC certified?

A: Yes. Our PAC meets NSF and other relevant standards.
