When it comes to water purification, few chemicals have turned into such a key player as Polyaluminium Chloride (PAC). This inorganic polymer coagulant acts like a steady helper in getting clean tap water, clear rivers, and smooth-running industrial setups. In 2025, its role keeps getting bigger. That's because water shortages and dirt in the water are getting worse all over the world. 

And if you're looking to buy PAC or other stuff for water cleaning, Hainan Horizon Import and Export Co., Ltd. stands out. They're one of China's top sellers—an ISO-certified maker that mixes research, big-batch making, and shipping to places far and wide.

What Is Polyaluminium Chloride (PAC)?

Polyaluminium Chloride, or PAC for short, is an inorganic polymer coagulant. It comes from linking aluminum ions with chloride ions. Put it simply, it grabs tiny bits floating in water. Those bits clump up. Then they sink or get caught in filters. It's different from old-school coagulants like alum. PAC does its job well in a broad pH range, from 5.0 to 9.0. And it makes big, quick-to-drop clumps called flocs.

What makes PAC so handy? You see it everywhere. In treating water for drinking. In handling wastewater from cities or factories. Even in setups like boilers or cooling towers for industry. It comes as a solid or a liquid. Either way, it acts fast. You need less of it. And it saves money in the long run. 

For spots that need super clean stuff, the Spray Polyaluminium Chloride from Hainan Horizon fits the bill. They use a special drying method called spray drying. It gives high mixability in water. And it leaves very little junk that won't dissolve. That's perfect for drinking water. Or for picky industries where tiny specks could cause trouble.

What Are the Key Application Scenarios?

PAC's uses go way past just city water cleaning. Its makeup lets it tackle all sorts of junk in water. From floating dirt to heavy metals that shouldn't be there. Take a river near a factory town. Without PAC, the water might stay murky for weeks after a spill. But with it, things clear up fast.

How Does PAC Work in Drinking Water Treatment?

In processing water for people to drink, PAC steps in as a coagulant. It pulls small floating particles together into bigger clumps. Those clumps drop fast. So the next steps, like filtering or letting stuff settle, go smoother. The water ends up clearer. It tastes better too. Lots of new plants pick PAC these days. It doesn't call for extra bases to balance things. And if you add a bit too much, it won't make bad side effects.

What Role Does PAC Play in Industrial and Municipal Wastewater Treatment?

PAC shines with its grab-and-hold power. It cuts down on cloudiness, plant-based gunk, and measures like COD or BOD in wastewater from factories or cities. In fields such as making paper, dyeing cloth, or digging for minerals, it teams up with other cleaners. This helps dry out sludge better. And it leaves fewer bad bits behind.

For really tough jobs—like water full of thick mud or deep colors—some spots turn to Basic Aluminum Chloride. It makes the clumps heavier. They sink quicker too. 

How Is PAC Used in Cooling and Boiler Water Systems?

PAC can help condition water in these spots too. It keeps down buildup on pipes, rust eating away at metal, and bugs growing where they shouldn't. In places where water loops around a lot, steady quality matters big time. So PAC fits right into full water care plans for making things or generating power.

Say you're running a power plant in Texas during hot months. The cooling towers guzzle water. Without good treatment, scales form and efficiency drops. PAC steps in quietly. It binds those troublemakers early.

What Are the Advantages of Using PAC?

PAC isn't just about the science. It's about real-world wins that save time and cash.

High Efficiency Across a Wide pH Range

It keeps up good clumping action in sour or basic waters. This flexibility cuts the need to fiddle with pH upfront. So you spend less on extra chemicals. And the daily work gets simpler.

Cost-Effective and Easy to Handle

PAC packs more punch per scoop. Its stickiness grabs better, so you use smaller amounts for the same clean job. Plants switching over often see bills drop by up to 30%. And handling? It's straightforward. Mix it in, watch it work. No fancy gear needed.

Environmentally Sound

PAC pulls out extra nitrogen and phosphorus from outgoing water. That helps stop overgrowth of algae in lakes and rivers. With rules on water care getting stricter everywhere, this friendly side scores points. It's like giving nature a hand without extra effort.

What About Safety and Environmental Considerations?

PAC works great, but the thick stuff can sting a little on skin. So grab gloves, eye shields, and cover-up clothes before you touch it. Safety first, always.

Watchdogs on the environment keep an eye on any PAC leftovers in cleaned water. Smart dosing and checks make sure it does good without adding fresh problems. Done right, PAC actually boosts water health. It cuts down nasty nutrients. And overall, things look brighter for streams and such.

Hainan Horizon’s PAC items, like Spray Polyaluminium Chloride, pass big safety and quality checks. Things like ISO9001 and ISO14001. They also stick to the GB15892-2020 rule for PAC good for drinking water. That's peace of mind when you're shipping across borders.

What Are the Development Trends and Innovations?

Tech for PAC keeps moving forward at a good clip. New versions aim for cleaner makeup, quicker dissolving, and speedier dropping of clumps. Take "high-purity PAC." It's popping up in spots like drug making or tiny chip factories. There, even a speck of wrong stuff could ruin a batch.

Hainan Horizon leads the pack here. They're pouring money into fresh ideas for coagulants that mix strong work with green ways. Check out their lineup. You'll spot custom blends helping everyone from city pipes to factory recycle loops.

Water troubles—short supplies and more trash in streams—keep piling up globally. So PAC's spot in the mix grows. That means more need for solid sellers with know-how and shipping smarts. Like Hainan Horizon Import and Export Co., Ltd. They're steady as they come.

FAQ

Q1: What is the main use of PAC?
A: PAC mainly works as a coagulant in treating drinking water and wastewater. It pulls out floating solids and other junk.

Q2: Is PAC safe to handle?
A: When you thin it out, PAC is okay to touch. But the strong version bites a bit. So suit up with gear when mixing or using it.

Q3: How does PAC improve wastewater treatment?
A: PAC boosts the clumping and dropping process. It cuts floating bits, COD, and other bad stuff. So the output water runs clearer. And you end up with less sludge to deal with.
