Shandong Ecolink Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of industrial grade pac 28% in China, featured by quality products and good service. If you're going to wholesale high quality industrial grade pac 28%, welcome to get more information from our factory.
Product Introduction
In water treatment processes, common problems include: high dosage, unstable performance, large batch differences, and uneven dissolution.
This industrial-grade PAC 28% water treatment agent (polyaluminum chloride) is optimized to address these issues.
Compared with traditional products, this PAC 28% polyaluminum chloride has:
Lower dosage, reducing cost
Faster reaction speed, improving efficiency
Stronger adaptability to water quality, reducing debugging
At the same time, this PAC flocculant 28% content water treatment chemical has stable quality, making it more suitable for long-term supply.
👉 An industrial-grade PAC 28% flocculant that saves cost, is more stable, and suitable for continuous sales.
Product Overview
Product Name: Industrial-grade PAC 28% water treatment agent (polyaluminum chloride)
Common names: PAC, polyaluminum, Polyaluminium Chloride, PAC coagulant, PAC flocculant
This product is prepared through controllable polymerization reactions. It belongs to high-content PAC polyaluminum chloride 28% products and is widely used in various water treatment systems.
Before each batch of polyaluminum chloride leaves the factory, three things must be done:
Test aluminum content
Test basicity
Conduct cylinder sedimentation comparison (side-by-side with the previous batch)
You may not see the reaction kettle, but you can see our standards from the sedimentation speed of every bag of product.

Product Advantages
Advantage 1: Predictable sedimentation curve
Because sedimentation speed is tested for each batch, you can calculate sludge level changes in sedimentation tanks in advance.
→ No need to adjust sludge discharge frequency daily, reducing site visits.
Advantage 2: Dosing pumps do not clog
Because of plate-frame filtration + spray drying dual impurity removal, insoluble matter ≤0.4%.
→ Extends diaphragm pump and metering pump valve ball life, saving maintenance costs.
Advantage 3: No performance loss at low temperature
Because basicity is deliberately controlled within 68–75% mid-low range, dissolution speed at 5°C water only slows by 15%.
→ Northern customers do not need heating systems, saving electricity and installation costs.
Advantage 4: Different batches can be mixed
Because reaction curves are locked, old and new batches can be mixed in any ratio without obvious change in floc formation.
→ No need to clean tanks when switching batches, saving water and labor time.

FAQ
Q: What is the difference between industrial-grade PAC 28% and drinking water grade?
A: Drinking water grade has stricter requirements for heavy metals such as arsenic and cadmium, and costs 30–50% more. Industrial-grade PAC 28% is not suitable for tap water plants but is fully sufficient for sewage and industrial wastewater.
Q: Can it be used together with polyacrylamide (PAM)?
A: Yes. Add PAC first, stir for 30 seconds, then add PAM. If the order is reversed, flocs will break.
Q: Will it lose effectiveness over time?
A: Under dry, light-protected, unopened inner bag conditions, aluminum content decreases by no more than 0.3% within 12 months.
Q: What type of water is most difficult to treat?
A: High-concentration emulsified wastewater (cutting fluids, oily wastewater). It is recommended to demulsify first. Other water types can be dosed directly.
Q: What water qualities is PAC 28% suitable for?
A: Suitable for various industrial and municipal water treatment scenarios.
Q: Does it support customization?
A: Supports packaging and partial parameter adjustments.
Q: Is it prone to caking?
A: Stable under normal storage conditions.
Q: Are samples provided?
A: Sample testing is supported.
