PAC, AC, and ALU: Differences and Selection Guide for Water Treatment Materials

In the field of water treatment, choosing the right material is crucial. PAC, AC, and ALU are three commonly used water treatment materials, each with its own unique advantages and适用范围. This article will delve into the differences between these three materials to help you make an informed decision.

PAC (Poly Aluminum Chloride)

Poly Aluminum Chloride (PAC) is an inorganic polymer coagulant with properties of adsorption, coagulation, and sedimentation.

Features:

-Excellent coagulation effect, low dosage, and low cost.

-Strong adaptability, can be used to treat various water qualities.

-Simple operation and easy management.

Applications:

Drinking water treatment

Industrial wastewater treatment

Municipal sewage treatment

AC (Activated Carbon)

 Activated Carbon (AC) is a porous adsorbent with a developed pore structure and a large specific surface area.

Features:

-Strong adsorption capacity, can effectively remove organic matter, heavy metals, pigments, etc. from water.

-Good chemical stability, resistant to acid and alkali corrosion.

-Can be regenerated and reused, with a long service life.

Applications:

-Advanced drinking water treatment

-Industrial wastewater treatment

-Air purification

ALU (Aluminum Salts)

Aluminum salts are commonly used coagulants, including aluminum sulfate, aluminum chloride, etc.

Features:

-Excellent coagulation effect, low price.

-Long history of use, mature technology.

-Certain corrosiveness to equipment.

Applications:

-Drinking water treatment

-Industrial wastewater treatment

-Municipal sewage treatment

How to Choose the Right Material?

Choosing the right material requires considering the following factors:

-Water Quality: Different water qualities require different treatment materials. For example, PAC or ALU can be chosen for treating high-turbidity water, while AC can be chosen for treating water containing organic matter.

-Treatment Objectives: Different treatment objectives require different materials. For example, PAC or ALU can be chosen for removing suspended solids from water, while AC can be chosen for removing organic matter.

-Cost: Different materials have different costs. It is necessary to choose the right material according to the budget.

Conclusion

PAC, AC and ALU are all important water treatment materials, each of which has its own unique advantages and scope of application. Choosing the right material can effectively improve water treatment efficiency and reduce treatment costs.
