1. Overview
What is Poly Aluminum Chloride?
Poly Aluminium Chloride (PAC) is a highly efficient coagulant with the chemical formula [Al2(OH)nCl6-n]. It is widely used in water treatment processes to remove suspended solids, organic matter, and other contaminants. PAC is available in both liquid and powder forms and is known for its ability to perform effectively over a wide pH range. It works by destabilising and aggregating particles, making it easier to remove them through sedimentation or filtration.
Poly Aluminium Chloride is preferred in many water treatment applications due to its quick reaction time, reduced sludge production, and the ability to operate efficiently in cold temperatures. At Polymaster, we provide specialised storage and handling solutions for PAC, ensuring its stability and effectiveness in various industrial and municipal water treatment processes. Proper storage is essential to maintain the quality and reactivity of PAC.
What material is compatible with Poly Aluminum Chloride?
1.5SG with chemical grade (octene) PE.

3. Chemical Storage Solutions
Tanks for Poly Aluminum Chloride Storage
Polymaster’s Self-Bunded range is the ultimate storage solution for Poly Aluminum Chloride. This range incorporates the bund with the storage tank, providing a bund capacity of 110% of the internal storage tank. In the unlikely event of a leak, this design prevents chemicals from coming into contact with the environment and personnel. Polymaster’s chemical tanks are not rainwater tanks and follow strict QA processes, such as hydro testing each tank to ensure they are 100% leak-proof.

Small chemical storage tanks offer advantages over large storage tanks in terms of flexibility, accessibility, and safety. Their smaller size allows for easier handling and transportation, making them ideal for labs, small-scale industrial operations, and fieldwork where mobility is key.
These tanks are suitable for environments with limited space, allowing convenient storage in confined areas. They also facilitate precise inventory management, reducing the risk of overstocking and chemical waste. They can be easily replaced or cleaned, ensuring better hygiene and reducing cross-contamination.
Enclosed IBC Bund
IBC Storage (1,000L)
Intermediate Bulk Containers (IBCs) are versatile and widely used due to their large capacity and convenient design.
Polymaster’s unique Enclosed IBC Bund solves many of the problems associated with IBC storage and chemical/fluid decanting in a weather-resistant, purpose-built enclosure.
Constructed from high-grade polyethylene, the Polymaster Enclosed IBC Bund allows for easy forklift movement of IBCs in/out, with a simple connection made to a 250 litre day tank, eliminating OH&S issues associated with IBC handling.

Large chemical storage tanks offer significant benefits over small tanks in terms of efficiency, cost-effectiveness, and operational capacity. These tanks store substantial volumes of chemicals, reducing the need for frequent refilling and minimising downtime in industrial processes. This efficiency translates to lower storage costs and the ability to purchase chemicals in bulk at discounted rates.
Large tanks also centralise storage, simplifying inventory management and logistics while ensuring a continuous supply of necessary chemicals. Fewer large containers reduce the risk of leaks and spills, and these tanks are equipped with advanced safety features to handle hazardous materials securely.

5. Applications
What are the applications for Poly Aluminum Chloride?
Poly Aluminum Chloride is a versatile chemical with a wide range of applications across various industries.
Here are some of its primary uses:
Water and Wastewater Treatment
PAC is widely used in the treatment of drinking water and wastewater. It acts as a coagulant, helping to remove suspended solids, organic matter, and other contaminants by aggregating them into larger particles that can be easily removed through sedimentation or filtration. PAC is especially effective in treating turbid water and improving water clarity.
Oil and Gas Industry
PAC is used as an additive in drilling fluids in the oil and gas industry. It helps control the viscosity and filtration properties of the drilling mud, improving the efficiency of drilling operations and reducing the risk of blockages and other issues during drilling.
6. FAQ
Poly Aluminum Chloride is a corrosive chemical. It is important that it is stored within a container that is resistant to corrosive chemicals. This means within a tank or container that is built for the purpose of holding aggressive chemicals.
Store Poly Aluminum Chloride in a cool, dry, and well-ventilated area away from direct sunlight.
Use containers made of compatible materials, such as our 7032 grade hexene 1.5SG to store Poly Aluminum Chloride. Never store in metal containers. It will attack metal resulting in a spill.
Store Poly Aluminum Chloride separately from other chemicals, particularly strong acids & bases, which can react with it and cause dangerous reactions.
Ensure that Poly Aluminum Chloride containers are tightly sealed and labelled with the proper hazard warnings.
Regularly inspect and check your tank for any signs of damage or wear that may occur and get them repaired immediately.
When it comes to storing Poly Aluminum Chloride, what you are storing it with is just as important as you can cause serious harm to people on-site or the environment around you. Poly Aluminum Chloride should not be stored with strong acids & bases or any other chemicals that can react with it.
When it comes to the storage and handling of Poly Aluminum Chloride it is important that it is handled safely, and that everyone on-site is kept safe. Here are a few guidelines to follow to keep your workplace safe:
Store the chemical in its own designated area, away from other chemicals and direct sunlight. Poly Aluminum Chloride may become unstable when stored for a long time at temperature above 40°C. It decomposes on heating, emitting hydrogen chloride gas and other toxic fumes.
With any type of corrosive chemical using the appropriate personal protective equipment (PPE) such as gloves, goggles and face shield is a must, Poly Aluminum Chloride is no different.
Avoid inhaling Poly Aluminum Chloride fumes or mist, which can cause respiratory irritation and other health problems.
Always handle Poly Aluminum Chloride with care and avoid splashing or spilling it.
Do not mix Poly Aluminum Chloride with any other chemicals or substances without first consulting a qualified professional.
