The Netherlands is globally renowned for its advanced and strictly monitored water management systems. Under the directives of Rijkswaterstaat and the KIWA certification authorities, Dutch water boards (Waterschappen) enforce some of the highest standards in Europe regarding municipal sewage effluent, phosphorus recovery, and industrial wastewater treatment. Traditional coagulants like alum or ferric chloride, while effective, often lead to elevated sludge volumes and residual chloride concentrations. This is where Aluminum Chlorohydrate (ACH) steps in as a critical technology differentiator.
ACH ($Al_2(OH)_5Cl \cdot sH_2O$) is a highly concentrated, polymeric aluminum coagulant characterized by its high basicity (typically 83% to 84%). Unlike standard coagulants, its advanced chemical structure delivers significantly more charge-neutralizing capacity per mole of aluminum, resulting in rapid micro-floc formation, exceptional turbidity reduction, and minimised chemical sludge generation. For Dutch industrial operators—especially in food processing, paper mills, and electronics manufacturing located in hubs like Rotterdam, Brabant, and Gelderland—reducing sludge volume directly translates into lower transport and incineration costs, aligning perfectly with the country's carbon neutrality goals.
| Chemical Property | Aluminum Chlorohydrate (ACH) | Polyaluminium Chloride (PAC) | Aluminum Sulfate (Alum) |
|---|---|---|---|
| Al2O3 Content (%) | 23.0% - 24.0% (Liquid) / 46% - 48% (Solid) | 10% - 17% (Liquid) / 28% - 30% (Solid) | 8% (Liquid) / 17% (Solid) |
| Basicity (%) | 83% - 84% | 50% - 80% | 0% (Acidic) |
| Sludge Production | Extremely Low (Up to 50% reduction) | Moderate | High |
| pH Consumption | Minimal (Saves alkaline dosing buffer) | Moderate | Significant (Requires lime/caustic soda) |
The production of premium ACH involves the controlled reaction of high-purity metallic aluminum with hydrochloric acid. At our state-of-the-art facilities, this process is monitored in real-time using digital DCS systems to ensure that the basicity never falls below 83%. This high level of basicity means that the aluminum species are pre-polymerized into stable polymeric clusters, primarily the $Al_{13}$ and $Al_{30}$ polycations. These molecules are incredibly effective at neutralizing negative colloidal charges on organic matter and suspended solids in cold waters, which is a frequent challenge during Dutch winter seasons.
Founded in 1998, Wuxi BS Water Treatment Chemicals Co., Ltd. possesses advanced production technology and rich management experience. We specialise in producing a series of water treatment products for the treatment of drinking water and various types of domestic and industrial wastewater. Our high-efficiency ACH and PAC products are optimized to support strict regulatory requirements worldwide.
