Description
Aluminum Chlorohydrate (ACH)
Product Description
Aluminum Chlorohydrate (ACH) is produced using advanced manufacturing techniques and high-quality raw materials. It features low impurities, high molecular weight, and excellent flocculation performance.
Applications
ACH is widely used as a coagulant in:
- Purified water and drinking water treatment
- Municipal water supply systems
- Industrial wastewater treatment
- Papermaking industry
- Personal care and pharmaceutical products (e.g., antiperspirants)

Usage Instructions
- Liquid ACH can be used directly or diluted before use. Solid ACH must be dissolved in water before dosing.
- Dilution Ratios:
- Solid: 1%–10%
- Liquid: 2%–20% (by weight)
- Effectiveness is generally unaffected within this concentration range.
-
-
- Dosage Guidelines:
- Liquid ACH: 2–20 g/ton of water
- Solid ACH: 0.5–8 g/ton of water
- Final dosage should be determined based on jar tests and field trials.
-
Packaging & Storage
- Solid ACH: 25 KG woven bags with inner plastic liner; custom packaging available upon request.
- Liquid ACH: Supplied in IBC tanks, 200 KG PE drums, or container flexitanks.
- Storage: Keep solid ACH in a cool, dry, and well-ventilated place. Protect from moisture and rain during transport.
