Poly Aluminum Chloride Storage
Poly Aluminium Chloride (PAC) is a corrosive coagulant used to treat drinking water and wastewater, and as a drilling fluid additive. Polymaster supplies storage and dosing solutions suited to its handling requirements.
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.

FAQs
Frequently Asked Questions
Got a question about storing or dosing Poly Aluminum Chloride? Here’s what our customers ask most — from best-practice storage to safe handling and what to avoid mixing it with.
What is the best way to store Poly Aluminum Chloride?
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.
Best practices for storing Poly Aluminum Chloride
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.
What not to store with Poly Aluminum Chloride
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.
Chemical Storage & Handling
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.
