Hey there! I’m a supplier of Polyaluminum Chloride (PAC), and I often get asked about the storage conditions for this stuff. So, I thought I’d write a blog post to share some insights on how to store PAC properly. Polyaluminum Chloride

First off, let’s talk about what PAC is. Polyaluminum Chloride is a common water treatment chemical. It’s used to clarify water by removing impurities and suspended particles. It’s super effective and widely used in various industries, like water treatment plants, swimming pools, and even in some industrial processes.
Now, onto the storage conditions. The most important thing to keep in mind is that PAC should be stored in a dry place. Moisture is the enemy here. If PAC gets exposed to too much moisture, it can start to clump up. And once it clumps, it becomes a real pain to use. You don’t want to deal with a big, solid block of PAC when you’re trying to treat water. So, make sure the storage area is dry and well – ventilated.
A cool environment is also ideal. High temperatures can cause PAC to degrade over time. If it’s stored in a place that’s too hot, the chemical properties of PAC can change, and its effectiveness as a water treatment agent can be reduced. I’d recommend keeping the storage temperature below 30°C (86°F) if possible.
Another thing to consider is the packaging. PAC usually comes in bags or drums. The packaging should be intact. If there are any holes or tears in the packaging, moisture and air can get in, which can lead to the degradation of the product. So, always check the packaging before storing it. And if you open a bag or drum, make sure to seal it properly after use. You can use a clip or a sealant to keep the air and moisture out.
It’s also a good idea to store PAC away from other chemicals. Some chemicals can react with PAC, which can not only damage the PAC but also create safety hazards. For example, strong acids or alkalis can react with PAC and cause chemical reactions that you don’t want. So, keep PAC in a separate area away from other chemicals.
When it comes to long – term storage, you need to be extra careful. If you’re storing PAC for a long time, you should periodically check the product for any signs of degradation. Look for changes in color, texture, or smell. If you notice any of these changes, it might be a sign that the PAC is no longer good to use.
Now, let’s talk about the storage containers. If you’re using drums, make sure they are made of a material that is resistant to corrosion. PAC can be corrosive, especially in high concentrations. So, using a corrosion – resistant drum can prevent leaks and damage to the product. Plastic drums are a popular choice because they are relatively inexpensive and resistant to corrosion.
If you’re using bags, make sure they are made of a strong and durable material. The bags should be able to withstand the weight of the PAC and protect it from the environment. And don’t stack the bags too high, as this can cause the bags at the bottom to burst.
In addition to the physical storage conditions, it’s also important to keep proper records. Keep track of when you received the PAC, when you opened it, and how much you’ve used. This can help you manage your inventory and ensure that you’re using the product before it expires.
I know some of you might be thinking, "Why does it matter so much? Can’t I just store it anywhere?" Well, improper storage can lead to a lot of problems. If the PAC degrades, it won’t work as well in water treatment. This means you’ll have to use more of it to achieve the same results, which can be costly. And in some cases, using degraded PAC can even lead to poor water quality, which can have serious consequences, especially in applications like drinking water treatment.
So, to sum it up, here are the key points for storing Polyaluminum Chloride:
- Keep it in a dry and well – ventilated place.
- Store it in a cool environment, preferably below 30°C.
- Make sure the packaging is intact and seal it properly after use.
- Keep it away from other chemicals.
- Use corrosion – resistant storage containers.
- Keep proper records of the product.
