Sydney’s water grid relies heavily on large catchment systems like Warragamba Dam, complemented by the Sydney Desalination Plant to maintain supply security during drought cycles. Raw water sources in New South Wales can experience extreme swings in turbidity, total organic carbon (TOC), and alkalinity following storm events. This volatility requires high-performance coagulants that remain effective across a broad pH range. Aluminum Chlorohydrate (ACH) has emerged as the coagulant of choice for advanced water treatment facilities in the region.
Compared to traditional metal salts such as alum (Aluminum Sulfate) or low-basicity Polyaluminum Chloride (PAC), ACH features a high basicity rate—typically around 83%. This high concentration of pre-polymerized polymeric aluminum species, primarily the Al13 "Keggin" ion, delivers high positive charge density. As a result, it achieves rapid destabilization of negatively charged colloidal particles and organic matter with minimal consumption of the water's natural alkalinity.
Unlike alum, which consumes substantial bicarbonate alkalinity and depresses pH, ACH maintains the system's pH levels. This reduces or eliminates the need for post-treatment pH adjustments with lime or caustic soda, lowering chemical handling hazards and operational costs for Sydney facilities.
ACH reactions produce highly compact, dense flocs that settle quickly. This translates to significantly lower wet sludge volumes compared to metal sulfates, reducing the load on sludge dewatering equipment and lowering landfill disposal costs under NSW EPA guidelines.
As a pretreatment coagulant for microfiltration, ultrafiltration, and reverse osmosis, high-purity ACH reduces the concentration of dissolved organic foulants without introducing excess particulate carryover, extending the operational life of expensive membrane modules.
Australia’s chemical supply chains are vulnerable to global freight disruptions and domestic logistics bottlenecks. For critical water treatment chemicals like ACH, Sydney water utilities and industrial plants are shifting away from "just-in-time" supply chains to structured multi-source partnerships. Wuxi BS Water Treatment Chemicals Co., Ltd. addresses this need by combining high-capacity manufacturing in Wuxi, China, with robust shipping channels through Port Botany.
Our strategic manufacturing capabilities feature over 500,000 tons of annual production capacity, supported by a finished product warehouse holding over 20,000 tons. This buffer protects Sydney municipal councils, paper manufacturers, and mining projects from sudden global market shortages. We coordinate with local distributors to ensure that deliveries of bulk liquid ACH or dry powder variants comply with the strict Australian Standard AS 3780 for the safe storage and handling of corrosive substances.
Founded in 1998, Wuxi BS Water Treatment Chemicals Co., Ltd. combines advanced manufacturing technology with deep application expertise. We specialize in high-basicity coagulants and high-molecular-weight flocculants for drinking water and complex industrial wastewater treatment.
Our R&D department collaborates with leading chemical research institutions to continuously optimize the polymerization, basicity, and active content of our products. This ensures outstanding performance in cold-water coagulation, high-TOC treatment, and low-sludge applications.

Answers to common questions regarding chemical performance, packaging options, and shipping protocols for Sydney customers.
Aluminum Chlorohydrate (ACH) is a highly concentrated aluminum polymer with a basicity level of 83% and an Al2O3 active content of 23% in liquid form. Standard Polyaluminum Chloride (PAC) typically features a basicity range of 50% to 80% and contains 10% to 15% Al2O3. ACH's higher basicity provides stronger charge neutralization, resulting in lower sludge volumes, faster settling times, and minimal impact on water pH compared to PAC.
Yes. Our high-purity ACH and white PAC (PAC-01) are manufactured under strict ISO 9001 and ISO 14001 quality systems. They meet the low heavy metals and high active ingredient criteria required to comply with the Australian Drinking Water Guidelines (ADWG) and NSF/ANSI Standard 60 equivalents. We provide comprehensive COA (Certificate of Analysis) and SDS (Safety Data Sheet) documents with every shipment.
Our standard production lead time is 7 to 10 days from order confirmation. Ocean freight from Shanghai port to Port Botany in Sydney typically takes 14 to 21 days. We offer flexible trade terms, including FOB, CIF, and CFR, and accommodate various packaging preferences such as 1000L IBC tanks, 200L drums, and 25kg bags for dry powders.
We operate fully automated production lines equipped with real-time temperature, pH, and concentration monitoring. Our in-house QC laboratory analyzes samples from every production run, verifying parameters like basicity, active Al2O3 content, pH value, density, and heavy metal concentrations. Retained samples from each batch are stored for 12 months for verification and traceability.
