PAC Chemicals, the full name is poly aluminium chloride, can be used for drinking water, wastewater and pond water treatment, as well as sedimentation aids and flocculants in aquaculture. Its aluminum content from 28% to 32% helps clean water to protect the environment. The colors of PAC powder are white, light yellow, and yellow, but PAC chemicals with different colors are also very different in application and production technology.

There are three common types of PAC for water treatment in Fengbai company. They are white 30% PAC for drinking water treatment, light yellow PAC 30% for drinking water and yellow PAC 28% for industrial waste water. The raw materials of white PAC chemical are high-quality aluminum hydroxide powder and hydrochloric acid, and the production process is the most advanced technology spray drying method. The raw materials of yellow PAC are aluminum hydroxide powder, hydrochloric acid, and a little calcium aluminate powder. The production process is drum drying or spray tower drying.

PAC Chemicals for Water Treatment

  • Can be widely used in drinking water and wastewater treatment. Because PAC chemical has the widest range of pH and temperature applications compared to other water treatment chemicals. It can effectively help factories increase production capacity and reduce operating costs.
  • PAC chemicals have very little effect on pH, thereby minimizing the need for pH adjustment chemicals, further reducing operating costs.
  • It is used in the paper industry to improve drainage in neutral and alkaline processes, and as a retention aid, it increases sizing efficiency and reduces cationic requirements.
  • PAC chemical has good water solubility. During the dissolution process, it is accompanied by a series of physical and chemical reactions such as electrochemistry, coagulation, adsorption and precipitation. The flocs form quickly and coarsely, with high activity and rapid precipitation, and the purification effect on high turbidity water is very obvious.

  1. Mix the PAC into the solution according to the prescribed dose.
  2. Put the diluted solution into the sewage source to be treated, according to the formula 1-10g/m3 domestic water, 20-200g/m3 industrial waste water.
  3. Based on the test formula, the exact dose used for treatment will be measured. After the clear air has settled, it can be used after being sterilized and boiled. The common dosage of river water, lake water and pond water is: 1-10g/m3 water, depending on the turbidity.
  4. For aquaculture water sources, PAC should be mixed into a 10-20% solution, then placed in the treated water and stirred to clarify.
