Tokyo is not merely a global commercial hub; it is home to highly concentrated, high-tech manufacturing, precision electronics assembly, advanced electroplating, and metal finishing facilities. Sites in special industrial areas like Ota City (Ota-ku), Koto City, and the Tama district represent the cutting edge of global components fabrication. However, Tokyo's dense urban setting demands unparalleled ecological responsibility. The Tokyo Sewerage Bureau and the Water Pollution Prevention Act enforce some of the strictest heavy metal discharge limits worldwide to preserve the sensitive ecological balance of Tokyo Bay.
For industrial operators in Tokyo, conventional metal precipitation methods often fall short of these stringent thresholds, especially when treating complexed copper, nickel, zinc, and trivalent chromium. Smedic Technology's advanced heavy metal removal agents utilize targeted organic chelating molecules that form insoluble, high-density floc particles, driving remaining metal concentrations well below parts-per-billion (ppb) levels.
In parallel, the global industrial sector is undergoing a massive shift towards Zero Liquid Discharge (ZLD) frameworks and circular economy models. Industries are looking for specialized suppliers who can deliver not just chemical agents, but optimized processes that reduce sludge footprint, lower processing energy, and recover clean recycled water.
Bridging class-leading chemical synthesis with targeted local applications for urban municipal and industrial systems.
Smedic Technology Co., Ltd., established in 2011, stands as a premier comprehensive solution provider specialized in environmental protection agents. We integrate advanced R&D, mass production, technical sales, and tailor-made engineering services. Smedic produces top-tier environmental protection agents covering municipal sewage, industrial wastewater, municipal tap water treatment, mineral processing, and specialized oilfield chemicals. We maintain a diverse product line exceeding 80 different formulations, backing our partners with a robust annual capacity exceeding 1 million tons.
Our corporate headquarters is located in Beijing, and we have established multiple wholly-owned, highly modernized production bases in Hebei, Guizhou, Shanxi, and other industrial clusters. To ensure streamlined logistics and reliable supply chains, we operate more than ten OEM partner factories and regional warehousing bases. Smedic’s domestic and international service network spans over 20 regions, actively treating over 20 million tons of sewage per day across 600+ urban wastewater facilities and 1,000+ industrial end-users.
Understanding how polymeric organic chelants outperform traditional hydroxide precipitation in complex industrial wastewater.
Standard heavy metal precipitation relies heavily on altering pH to form insoluble metal hydroxides. However, in the presence of strong complexing agents (such as EDTA, tartaric acid, citric acid, and ammonia commonly found in electroplating and semiconductor etching baths), metal ions remain trapped in soluble complexes. Smedic's heavy metal removal agents use advanced macromolecular organic chelants containing active sulfur-bearing dithiocarbamate (DTC) groups.
These reactive ligands possess a highly active affinity for heavy metal ions (specifically Cu2+, Ni2+, Cd2+, Pb2+, Zn2+, and Hg2+). They easily break down existing weak complexes, bonding directly with the metal ions to form robust, net-like cross-linked coordination polymers. These polymers exhibit minimal solubility even in extremely acidic or basic ranges, precipitating rapidly without requiring massive pH adjustments.
| Parameter/Feature | Traditional Hydroxide Treatment | Smedic Macromolecular DTC Chelators | Industrial Advantages |
|---|---|---|---|
| Target Concentrations | Hard to reach < 1.0 mg/L | Achieves < 0.1 mg/L (ppb levels) | Complies with strict Tokyo Sewerage Standards |
| pH Operation Window | Narrow (typically 8.5 to 9.5) | Wide operational range (pH 3 to 12) | Eliminates continuous acid/alkali dosing costs |
| Treatment of Complexed Metals | Ineffective; EDTA blocks precipitation | Breaks complexes to form stable precipitates | Highly effective for PCB and electroplating baths |
| Sludge Production & Density | High sludge volume, low density | Compact, fast-settling, low sludge volume | Reduces hazardous waste disposal fees by up to 40% |
Smedic operates a state-of-the-art research ecosystem composed of one dedicated academy, three research institutes, and five production-based labs. We are recognized as a National High-Tech Enterprise and a National Specialized, Refined, Unique and Innovative "Little Giant" Enterprise.
We work in close strategic collaboration with leading academic institutions including Tsinghua University (Association of Senior Scientists and Technicians), Shandong University, and the Beijing University of Technology. These collaborations translate scientific progress into high-efficiency water treatment chemicals.
Smedic holds over sixty Chinese patents, including more than 40 invention patents and 20 utility model patents. Our proprietary "Inorganic-Organic Covalent Bond Flocculant" received the prestigious 22nd China Patent Award and the First Prize for Technological Invention from the China Petrochemical Industry Association.
Where precision chemistry meets specific industrial processing needs.
Highly concentrated copper and nickel rinses require instant chelation. Smedic's agents break down ammonia and EDTA bonds, allowing operators to achieve deep compliance without replacing entire wastewater tanks.
Our formulations target complexed copper in circuit board micro-etching operations. By introducing organic sulfur precipitants, micro-electronics plants keep heavy metals below detectable levels.
Coal-fired power stations and municipal waste incinerators produce complex wash-water containing lead, mercury, and cadmium. Our thermal-stable chelators bind heavy metals directly within the scrubber circuit.
