PAC - Polyaluminium Chloride

What is PAC - Polyaluminium Chloride used for?

With this chemical, it may be a foreign substance to many people, but in certain industries, it is an indispensable substance in the water treatment industry.

Basic information to know about PAC - Polyaluminium Chloride

• About the definition: this product is a kind of aluminum alum that exists in the form of polymers (polymers). This chemical is also known as a coagulant. The molecular formula is [Al2(OH)nCl6-n]m. The chemical composition is polyaluminium chloride, and there is also a chlorine-based disinfectant.

• About color, state: This substance exists in two forms, solid form (capable of completely soluble in water) and liquid form. In solid form, PAC - Polyaluminium Chloride is a white, turmeric yellow and lemon yellow powder.

Applications PAC – Polyaluminium Chloride

About use: Currently, this chemical is being produced popularly and mass-produced to replace alum aluminum sulfate in the treatment of industrial wastewater as well as domestic wastewater.

Not coincidentally, industrial plants use PAC - Polyaluminium Chloride instead of using alum Aluminum Sulfate as before.

That's because this chemical has many advantages, specifically as follows:

Applications of the product are often found in water treatment such as: industrial wastewater treatment, feed water treatment, textile dyeing water treatment, paper industry water treatment, plating water treatment, river water treatment, etc. pond water, water treatment for textile dyeing, tanning water treatment...

The advantages of PAC - Polyaluminium Chloride in water treatment

• Limit the adjustment of source water pH like alum currently used. From there, it is possible to save the dose of chemicals (used to increase alkalinity) as well as accompanying equipment such as chemical tanks and metering pumps.

• There is a low dosage, large residues that are easy to settle.

• Chemicals have the ability to reduce the volume of sludge.

• Helps to increase the clarity of water after settling, at the same time prolonging the filtration cycle, and increasing the quality of water after filtration.

• As an sequestering agent, it greatly improves the properties of polymers in water, increasing the rate of solidification and agglomeration, even in the case of low water turbidity and low temperature. Furthermore, PAC is also an isolating agent that increases the storage capacity of the final product.

• After opening the packaging, the chemical does not bleed or clump.

PAC Industrial Wastewater Chemicals Market Supply to Europe Region, industry revenue reached approximately $1.31 billion in 2005 and grew to approximately $1.94 billion in 2012. Divided by application areas in raw water treatment, industrial wastewater treatment and chemical wastewater treatment. This market report covers antioxidants, biocides, coagulants, corrosion inhibitors, heavy metal scavengers, ion exchange resins, odor control agents and reverse osmosis in among other things for water treatment.

Methods of preservation:To preserve PAC - Polyaluminium Chloride, if in solid form, the user should keep it in a sealed bag, place it in a dry place, the storage temperature is room temperature. If in liquid form, users can keep it in plastic bottles or cans if they want to preserve it longer.
