Main Types of PAC




Industrial PAC



Filter grade PAC



Drinking grade PAC


Light Yellow

Drinking grade PAC



CAS Number: 1327-41-9

The main difference between industrial grade PAC and Filter grade PAC is the amount if water insoluble matter eg Industrial grade Water insoluble matter≥1.12% , Filter grade water insoluble matter≥0.6%

Please find attached COA’s for further clarification

  1. Industrial PAC 28%
  2. Filter grade PAC 28-29%

The main differences between white and yellow drinking grade PAC are as follows:


2)Basicity-White PAC has a low basicity value as compared to yellow PAC

3)Iron content- White PAC does not contain iron, Yellow PAC contains iron

Please find attached COA’s for further clarification

1)Drinking Grade PAC white(29-30%)

2)Drinking Grace PAC Light Yellow(29-30%)

Basic Polyaluminium chloride (PAC) Uses in Industries

Polyaluminium chloride (PAC) is a chemical compound that is widely used in various industries and applications. Here are some common uses of PAC:

  • Water Treatment: PAC is extensively used in water treatment processes, particularly in the purification of drinking water and wastewater treatment. It is effective in removing suspended solids, organic matter, and certain dissolved contaminants. PAC acts as a coagulant and flocculant, aiding in the clarification and sedimentation of particles.
  • Paper Industry: PAC is used in the paper manufacturing industry as a retention and drainage aid. It helps in improving the retention of fine particles, enhancing paper strength, and increasing the speed of paper machine operations.

  • Textile Industry: PAC finds application in the textile industry for the treatment of wastewater generated during various textile processing stages. It assists in the removal of dyes, pigments, and organic pollutants from textile wastewater, enabling compliance with environmental regulations.

  • Oil and Gas Industry: PAC is utilized in the oil and gas sector for oil-water separation processes. It helps in the removal of oil and suspended solids from produced water, enhancing the efficiency of oilfield operations and environmental protection.

  • Mining Industry: PAC is employed in the mining industry for the treatment of wastewater generated during mining operations. It aids in the removal of suspended solids and contaminants, allowing for the safe discharge or reuse of water.

  • Chemical Industry: PAC is used as a coagulant in various chemical processes, such as the production of dyes, pigments, and pharmaceuticals. It assists in the separation and purification of desired compounds from reaction mixtures.

  • Other Applications: PAC has additional applications in industries like cosmetics, food processing, and construction. In cosmetics, it is used as a clarifying agent in skincare products. In food processing, it can be used for water clarification or as a food additive. In construction, PAC can be used as a binder or flocculating agent in cement and mortar formulations.

These are just a few examples of the many applications of PAC. The specific application and dosage of PAC can vary depending on the industry, process requirements, and local regulations.
