Explore our high-performance line of products customized for rapid settling, high basicity, and low heavy metal residues in South Korea’s rigorous environmental landscape.
The Seoul Metropolitan Area, home to over 25 million residents and a critical node in the global high-technology supply chain, demands chemical water solutions that exhibit both maximum efficacy and impeccable environmental compliance. The Han River, the lifeblood of Seoul, experiences sharp seasonal variations in raw water turbidity due to the East Asian monsoon season. Managing these fluctuations while ensuring safe, clean water under the Seoul Metropolitan Government’s "Arisu" drinking water standards requires superior municipal-grade coagulants.
Wuxi BS Water Treatment Chemicals Co., Ltd. supplies high-basicity (83%-84%) Aluminum Chlorohydrate (ACH) optimized for the local South Korean market. Unlike general Polyaluminium Chloride (PAC), which has a basicity level around 50%-60%, ACH provides a dramatic reduction in chemical dosages, minimizes residual aluminum concentrations, and stabilizes the pH of treated water, reducing the need for secondary alkaline neutralizers such as sodium hydroxide (NaOH) or lime.
Furthermore, with the tightening of South Korea's Act on Registration and Evaluation of Chemical Substances (K-REACH), industrial procurement teams must partner with a supplier that maintains rigorous traceability, certified manufacturing workflows, and low trace-heavy-metal specifications.

Efficient removal of colloidal silica and heavy metal ions from fabrication facilities in Gyeonggi-do.
Optimized bulk logistics directly from our coastal-proximal factory to Incheon and Busan ports.
Understand the technical differences between Aluminum Chlorohydrate (ACH) and other inorganic salts in industrial wastewater applications.
| Parameters | High-Basicity ACH (Wuxi BS) | Standard PAC Liquid (10-15%) | Aluminium Sulfate (Alum) |
|---|---|---|---|
| Al₂O₃ Content (%) | 23% - 24% (Liquid) / 46% - 48% (Powder) | 10% - 15% | 8% - 17% |
| Basicity (%) | 83% - 84% | 50% - 75% | 0% (Acidic) |
| pH Range (1% water solution) | 3.5 - 4.5 | 3.5 - 5.0 | 2.5 - 3.5 |
| Heavy Metal Limits (As, Pb, Cd) | Strictly < 2ppm (Food/Municipal Grade) | < 10ppm | Variable, typically higher |
| Sludge Volumetric Output | Minimal (Up to 50% reduction vs Alum) | Moderate | Very High |
ACH molecules contain highly concentrated polymeric aluminum species ($[Al_{13}O_4(OH)_{24}(H_2O)_{12}]^{7+}$ or higher), which neutralize negatively charged particles in water faster than standard alum, requiring smaller chemical doses.
Because of its high basicity (pre-hydrolyzed at 83%+), ACH does not consume much alkalinity from the treated water. This prevents acidic drops and eliminates the cost of auxiliary chemical dosing in municipal and electronics runoff.
Ideal for rapid gravity settling and dissolved air flotation (DAF) processes utilized in Seoul municipal water utilities. It yields large, dense flocs that improve the efficiency of microfiltration and sand filters.

Global Enterprises Served
We provide chemical coagulants and customized solutions to target industrial and municipal water challenges in the greater metropolitan region.
The Gyeonggi semiconductor cluster (encompassing Yongin, Hwaseong, and Pyeongtaek) relies heavily on Ultra-Pure Water (UPW) loops. The pre-treatment of raw input water and the purification of complex Chemical Mechanical Planarization (CMP) wastewater are vital. Our ACH removes nanosized silica particles and chemical complexes effectively while preserving fragile downstream reverse osmosis (RO) membranes.
Automotive facilities in regions like Incheon and Gyeonggi generate painting line and electrocoating effluents loaded with suspended solids, polymers, and heavy metals. Standard coagulants lead to excessive, hazardous sludge disposal. High-basicity ACH dramatically cuts sludge mass, minimizing landfill and thermal destruction costs under South Korean law.
Seoul municipal reclamation centers demand high-purity chemicals to prevent heavy metal leaching into biological units. With stringent standards set by the Ministry of Environment for effluent total phosphorus (T-P), our ACH acts as a highly efficient precipitant that guarantees discharge values far below South Korea's regulated thresholds.
