The principle of operation of PAC is as follows: Aluminum ions destabilize suspended substances, organic substances, and heavy metals and promote the formation of these compounds together and form a floc. These flocs are very stable precipitates that settle quickly and are easily filtered.

General information about PAC deposition aids:

The formula of PAC is: {Al 2 (OH) n Cl 6-n}x


Trade name: PAC – Sedimentation aid, coagulant, flocculant

Appearance: PAC is sold commercially as a 10%-35% liquid PAC solution in 1000 liter IBC bottles or 20 liter to 200 liter cans. Or PAC yellow powder is packed in bags of 20 kg or 25 kg.

Employing PAC to coagulate organic and mineral colloids before deposition is a common practice in the water treatment business. PAC is therefore applied in:

- The treatment of wastewater that contains suspended residues, such as those produced in enterprises that manufacture ceramics, brick, paper, dye, process seafood, butcher cattle, employ metallurgy, or tan leather, among other things.

- Filter drinking water and domestic water before using it to make domestic water in rivers, lakes, and canals.

- Surface water treatment is ideal for home water supply plants, swimming pools, and water stations.

- Treatment of industrial and civic water supply...

- The aquariums for breeding aquatic creatures and purifying pond water.
Production of PAC sedimentation aids:

Liquid PAC is prepared by combining aluminum hydroxide with hydrochloric acid HCL and sulfuric acid at high temperature. Then treat the resulting product with calcium carbonate to enhance its basicity. The mixture is then mixed through a centrifuge to separate the liquid polyaluminium chloride from the solid product. Powdered polyaluminium chloride is produced from the reaction of hot HCl gas with aluminum powder to produce powdered PAC.

Dong A Business specializes in producing and marketing PAC around the country.

One of the few factories producing and providing PAC in Vietnam is Dong A Joint Stock Corporation, also known as Dong A Chemical. We have an advantage in creating PAC using a 10,000 m2 facility and cutting-edge ion-exchange membrane electrolysis technology since we have a source of HCL acid after making caustic soda from chlorine.

The Dong A firm is proud of its PAC manufacture in Vietnam. PAC products will benefit companies and the environment because of their exceptional benefits in terms of cleaning power, cost savings, and ease of use.
