Aluminium Chlorohydrate (ACH) is a highly concentrated synthetic inorganic polymer that has revolutionized municipal water treatment and industrial processes. With the empirical formula Al₂(OH)₅Cl·xH₂O, it represents the most basic form of the polyaluminium chloride family, boasting a basicity of up to 83%.
For B2B procurement managers asking "Apa itu Aluminium Chlorohydrate?" in industrial water purification, the answer lies in its structural efficiency. Due to its maximum possible hydroxyl group substitution and high cationic charge density, ACH functions as an incredibly powerful coagulant. It destabilizes suspended colloidal matter far more effectively than traditional salts like Alum (Aluminium Sulfate) or standard low-basicity Polyaluminium Chloride (PAC).
Traditional water treatment reagents require significant alkaline additives (like lime or caustic soda) to maintain stable water pH levels post-dosing. Because Aluminium Chlorohydrate is intrinsically basic (83% basicity), its hydrolytic reaction consumes minimal natural alkalinity. This eliminates secondary chemical dosing costs, decreases sludge volume by up to 50%, and minimizes corrosion risk within distribution pipelines.
Founded in 1998, Wuxi BS Water Treatment Chemicals Co., Ltd. has spent nearly three decades establishing itself as a global benchmark in the water treatment chemical manufacturing space. With a specialized focus on municipal drinking water purification, paper manufacturing additives, and complex industrial wastewater remediation, we supply robust chemical solutions tailored to global standards.
Equipped with automated reaction pathways, a dedicated in-house R&D center, and real-time spectrophotometric quality tracking, we guarantee high-purity coagulants that comply with stringent ecological regulations. We provide our global clients with end-to-end technical support, from initial water sample analytics to custom molecular weight configurations.
Drinking water facilities globally procure wholesale ACH because of its ability to clear high-turbidity surface water and low-temperature raw water. Its efficiency ensures strict regulatory compliance with municipal micro-particle standards.
Used as an active sizing agent and anionic trash scavenger. ACH aids in retaining fiber fillers, accelerates drainage velocity, and improves paper strength in modern closed-loop mill systems.
Cosmetic manufacturers require high-purity, low-iron ACH powder as the active antiperspirant ingredient. It forms temporary physical plugs in sweat ducts, offering safe and effective moisture control.
When negotiating supply contracts with manufacturers, procurement offices should enforce a dual-metric evaluation scheme: chemical compatibility and structural stability. Ensuring stable polymeric species distribution (specifically high concentrations of Al13 or Al30 polynuclear oligomers) prevents premature decomposition during ocean shipping transit. Ensure your supplier certifies low trace metal levels (Lead, Arsenic, Cadmium) under NSF/ANSI Standard 60 guidelines.
Modern production of high-basicity Aluminium Chlorohydrate relies on controlled hydrothermal synthesis of metallic aluminum or high-grade alumina with hydrochloric acid. Wuxi BS utilizes a proprietary process optimized for maximum aluminum polymeric species control.
This reaction path requires high-purity metallic aluminum sheets or active alumina hydrate, combined with concentrated hydrochloric acid under controlled pressure and temperature:
By shifting the stoichiometric ratio of Al:Cl, Wuxi BS achieves a targeted 83% basicity, limiting salt residues and preserving chemical activity.
Once synthesized, the monomeric Al-complexes undergo hydrothermal aging. This process causes hydrolytic condensation, creating stable, highly charged polynuclear structures like the Al13 Keggin ion [Al₁₃O₄(OH)₂₄(H₂O)₁₂]⁷⁺. These heavy clusters provide the rapid flocculation kinetics characteristic of ACH.
Wuxi BS is investing in carbon-neutral manufacturing technologies. Our upcoming facilities are shifting to closed-loop hydrogen recapture during the aluminum digestion phase. The captured hydrogen is recycled to heat our industrial spray-drying units. This advance reduces the carbon footprint of our solid ACH powder by 18%.
All water purification chemicals produced by Wuxi BS destined for municipal drinking water systems are certified under NSF/ANSI 60. This guarantees trace contaminant metrics remain far below strict EPA standards.
We maintain full compliance with the European Chemicals Agency (ECHA). Our REACH registrations guarantee seamless importation and distribution throughout the European Union and EEA markets.
Our production plants are managed under a unified Quality, Environmental, and Occupational Safety framework. This ensures production reliability, consistent chemical activity, and zero environmental incidents.
Logistics Infrastructure: Wuxi BS utilizes dedicated ISO-tank containers for liquid ACH deliveries to avoid product contamination. For solid powders, we use double-walled UV-resistant PP/PE woven super sacks (25kg to 1000kg) with moisture-barrier liners. This preserves chemical integrity during ocean transit and long-term warehouse storage in high-humidity climates, such as Southeast Asia and Latin America.
Production plant established in Wuxi, China, focusing on primary polyaluminium coagulant synthesis.
Officially renamed Wuxi Bisheng Water Treatment Agent Co., Ltd., expanding R&D on high-basicity ACH solutions.
Launched our global distribution network, exporting products to Southeast Asia, Europe, and North America.
Annual export sales surpassed $10,000,000 USD, driven by growing municipal contracts in APAC.
Established a dedicated foreign trade department to provide localized technical support and direct factory sales.
Liquid Aluminium Chlorohydrate (ACH) has a shelf life of approximately 12 months under proper storage conditions (avoiding extreme cold and direct sunlight). Solid ACH powder is chemically stable for up to 24 months, provided it remains sealed in its original moisture-proof PE liners.
While both are polymeric aluminum coagulants, ACH has a significantly higher basicity (83% compared to PAC's 50%-70%) and a higher Al2O3 concentration. This higher cationic charge density makes ACH more efficient, requiring lower dosage volumes and resulting in less residual sludge.
Yes. ACH is widely used as the active antiperspirant agent in deodorants. Wuxi BS manufactures a specialized high-purity, ultra-low iron grade specifically for cosmetic formulations to ensure safety and compatibility.
Every shipment is accompanied by a Certificate of Analysis (COA) specifying Al2O3 content, basicity, pH value, density, and heavy metal concentrations. We also provide safety data sheets (SDS) and NSF compliance certificates upon request.
