Canada possesses roughly 7% of the world's renewable freshwater resources, demanding sophisticated stewardship under rigorous regulatory frameworks. The purification of drinking water and treatment of industrial effluents in Canada are governed by guidelines set forth by Health Canada, provincial ministries (such as Ontario’s Ministry of the Environment, Conservation and Parks, and Alberta Environment and Protected Areas), and Environment and Climate Change Canada. These regulations strictly monitor disinfection by-products (DBPs), total organic carbon (TOC), and trace heavy metal residues in discharge streams.
Aluminum Chlorohydrate (ACH) has emerged as a key chemical coagulant to meet these standards. With the molecular formula Al2(OH)5Cl·2H2O, ACH is the most highly concentrated, inorganic aluminum-based coagulant available. Possessing a basicity rating of 83% to 84%—significantly higher than typical Polyaluminium Chloride (PAC) at 50% to 70% or Alum at 0%—ACH supplies the maximum density of pre-polymerized, polynuclear aluminum complexes, specifically the Al13 "Keggin" and Al30 oligomers.
During Canada's winter, surface water temperatures in municipal intake zones across regions like the Prairies, Ontario, and Quebec routinely drop to 0°C - 4°C. At these temperatures, conventional alum hydrolysis slows down significantly. ACH, however, relies on pre-formed polymeric structures that bypass temperature-dependent hydrolysis steps. It maintains rapid floc formation, high settling velocities, and effective turbidity reduction in freezing conditions without requiring auxiliary polymers.
Municipalities and industrial facilities across Canada are actively transitioning from alum and ferric chloride to high-basicity ACH for several operational reasons:
As a global producer with 27 years of industry experience, Wuxi BS Water Treatment Chemicals Co., Ltd. operates a manufacturing and distribution facility equipped to supply the Canadian market. By utilizing direct-sourcing options from our high-capacity factories, Canadian industrial distributors and direct consumers can bypass domestic supply bottlenecks and access optimized chemical supplies.
Our plant incorporates automated, digital solid-to-liquid feeding and real-time reactor tracking. This monitors pressure, temperature, and polymerization rates to yield highly consistent ACH batches. Operating with an annual capacity exceeding 500,000 tons and a finished product warehouse holding over 20,000 tons, we can prevent product shortages and secure long-term price stability for our Canadian partners.
Our ACH and customized polyacrylamide combinations speed up solid-liquid separation in mine wastewater. They aid in settling fine mature tailings in Alberta's oil sands operations, helping to clean recycling water and reduce storage pond volumes.
NSF/ANSI Standard 60 compliant ACH provides clean municipal drinking water in cold climates. It reduces natural organic matter (NOM) and organic color fractions, protecting communities from disinfection by-product formation.
Used widely in pulp and paper mills in British Columbia and Quebec, our ACH serves as an effective charge neutralizer for pitch control, anionic trash scavenging, and improving retention and drainage on paper machines.
Helps municipal plants near the Great Lakes basin meet strict phosphorus limits. ACH bonds with orthophosphates and particulate phosphorus to form stable flocs, reducing phosphorus levels to less than 0.05 mg/L.
Providing high-purity, low-iron solid and liquid ACH for Canadian personal care manufacturers. It meets antiperspirant standards with stable formulation options and reliable quality certificates.
Essential for Zero Liquid Discharge (ZLD) systems in manufacturing plants. ACH reduces silica and colloids to protect reverse osmosis (RO) membranes from fouling, helping extend membrane life and lower energy costs.
Our production factory was established in Jiangsu Province, focusing on standard inorganic coagulants and developing specialized formulas for municipal wastewater plants.
The company expanded and was renamed Wuxi Bisheng Water Treatment Agent Co., Ltd. We installed advanced glass-lined reactor units to produce high-basicity aluminum compounds.
Our chemical products began exporting to overseas markets. We established quality control systems to meet international standards (including ISO9001 and municipal specifications).
Annual export sales reached USD 10 million, with expanded distribution networks in North America, South America, and Southeast Asia.
We launched our dedicated foreign trade department and introduced digital, automated dosing and solid-feeding machinery, helping global buyers optimize their chemical feed systems.
Aluminum Chlorohydrate (ACH) is a specific high-polymer version of Polyaluminium Chloride (PAC) characterized by its high basicity (83%–84%) and high alumina content (typically 23% Al2O3 for liquid and 46%–48% for solid forms). Standard PAC has a basicity ranging from 50% to 70%. Because ACH is highly polymerized, it has a higher cationic charge density. This means it can destabilize negatively charged colloidal suspensions at lower dosages, requiring fewer chemical additions.
Standard alum depends on temperature-sensitive hydrolysis to form active flocs, a process that slows down in cold winter waters (0°C to 4°C). ACH bypasses this step because it is pre-polymerized, maintaining rapid floc formation and settling speeds even in freezing water. However, liquid ACH can freeze or crystallize at temperatures below -6°C. For winter deliveries in Canada, we recommend heated storage tanks, indoor storage, or using solid ACH alternatives.
In many municipal water sources with moderate to low alkalinity, yes. Traditional alum reduces alkalinity, which lowers water pH and often requires adding lime or caustic soda post-treatment to meet target drinking water pH levels. Because ACH has high basicity, it releases fewer hydrogen ions during coagulation, minimizing changes to pH and saving on alkalinity adjustment costs.
We ship liquid ACH in 1000L IBC totes, 200L drums, or flexitanks. For dry solid forms, we package in 25kg bags or 1000kg bulk bags. We handle shipping through FOB, CFR, and CIF terms to major Canadian ports such as Vancouver, Montreal, and Halifax. We work with leading ocean carriers to ensure reliable transit times and provide all required import documentation, including COAs, MSDS, and technical sheets.
Yes. Our R&D team can customize chemical basicity, Al2O3 concentration, and iron content to match your plant's water quality. We offer pilot sample testing to help optimize dosing levels before shipping bulk orders.
