Select target formulations specifically designed to yield rapid chemical precipitation of copper, nickel, zinc, chrome, and lead in industrial setups across Greater Bangkok.
The Greater Bangkok Area, spanning vital industrial hubs such as Samut Prakan, Pathum Thani, Samut Sakhon, and adjacent zones within the Eastern Economic Corridor (EEC), is experiencing unprecedented environmental scrutiny. With standardizations governed rigorously by the Department of Industrial Works (DIW) and the Ministry of Industry, factories operating electroplating, electronic circuit board (PCB) assembly, automotive manufacturing, and metal finishing lines face strict limits on effluents.
Traditional hydroxide precipitation methods fail when complexing agents like EDTA, citric acid, or ammonia are present in the wastewater. Our premium polymeric heavy metal precipitants are strategically engineered to target and break these complexes. This ensures that ionic concentrations of target pollutants—specifically Copper (Cu), Nickel (Ni), Zinc (Zn), Lead (Pb), and Chromium (Cr)—conform reliably to regulations, bringing residues down to under 0.1 ppm.
Comparative review of regulatory thresholds versus Smedic treated output.
| Metal Element | DIW Standard (mg/L) | Smedic Target (mg/L) |
|---|---|---|
| Nickel (Ni) | ≤ 1.0 mg/L | < 0.05 mg/L |
| Copper (Cu) | ≤ 2.0 mg/L | < 0.10 mg/L |
| Hexavalent Chromium | ≤ 0.25 mg/L | < 0.02 mg/L |
| Zinc (Zn) | ≤ 5.0 mg/L | < 0.20 mg/L |
A comparative overview of chemical kinetics and physical precipitation designed for high-salinity and complex industrial effluent.
Utilizing cross-linked polymeric structures loaded with dithiocarbamate (DTC) groups, the agent forms strong, multi-point coordination bonds with heavy metal cations. This ensures high-stability chelation, preventing the back-dissolution of sludge under varying pH conditions.
Unlike traditional inorganic coagulants, Smedic heavy metal removal agents feature a higher affinity for transition metals than common complexing agents like EDTA, NTA, and ammonia. It successfully extracts target ions directly from stable chemical complexes.
The generated flocs are dense, rapid-settling, and easily filterable. Smedic chemistry yields minimal sludge volume compared to standard lime precipitation, lowering chemical sludge disposal costs for enterprises in Thailand.
