Engineered to comply with Swiss GSchG guidelines. Rapid complexation and precipitation of toxic ions.
Geneva is not only a global diplomatic hub but also home to high-precision industries such as advanced watchmaking, micro-manufacturing, electroplating, and specialized chemical syntheses. These operations generate wastewater streams containing toxic heavy metal ions, including copper (Cu), nickel (Ni), chromium (Cr), and zinc (Zn), which are strictly regulated by the Swiss Federal Act on the Protection of Waters (GSchG) and Geneva cantonal environmental authorities.
Traditional chemical precipitation techniques often fail to reduce heavy metal concentrations to the fractional parts-per-billion (ppb) levels required by contemporary environmental criteria. The canton's industrial wastewater discharge demands highly effective chelating agents that operate over broad pH ranges and in the presence of strong complexing agents (such as EDTA or ammonia).
From a global perspective, the heavy metal removal market is shifting rapidly toward non-toxic, eco-friendly polymeric organic formulations that ensure zero-liquid discharge (ZLD) capability. Our high-capacity organosulfur formulations and composite inorganic-organic polymers provide Geneva manufacturers with a cost-efficient strategy to achieve compliance without upgrading entire physical plant infrastructures.
Undergoing precise chelation chemistry to immobilize toxic ions in challenging effluents.
Our heavy metal removal agent utilizes active sodium dithiocarbamate (DTC) derivatives that feature multiple sulfur-donor atoms. These groups have an affinity for transition metals, forming stable, insoluble coordination complexes that precipitate out of solution rapidly, even in the presence of strong chelating agents.
By pairing high-molecular-weight organic precipitants with advanced coagulants like Polyaluminum Chloride (PAC) or Polyferric Sulfate (PFS), our formulations build large, dense, easily filterable flocs. This reduces sludge volume and accelerates sedimentation rates.
Unlike hydroxide precipitation, which requires precise, metal-specific pH windows, our agents perform effectively across a pH range of 3.0 to 12.0. This allows for simultaneous multi-metal precipitation in a single reaction stage, saving chemical reagents and lowering processing costs.

How Smedic is positioning itself for the future of water treatment and heavy metal recovery.
Traditional low-molecular-weight organosulfur chemicals risk generating secondary odor and toxicity due to unstable metal-ligand ratios. The industry is moving toward macromolecular polymers with high-density chelating branches. These molecules wrap heavy metal ions in a multi-point coordinate cage, creating highly stable complex structures resistant to acid leaching.
Modern wastewater management is shifting from disposal to resource recovery. Smedic's R&D department is focused on designing selective chelating agents. In complex industrial processes containing multiple metals, these agents target and recover high-value metals like nickel, copper, and cobalt individually, providing industrial users with recycled materials.
Industrial wastewater flows are highly variable. Smedic is integrating real-time UV-Vis and electrochemical sensors with AI controller models to dynamically adjust the dosage of heavy metal removal agents. This minimizes chemical waste and prevents over-dosing, which can affect downstream filtration systems.
Smedic is committed to eco-friendly formulations, minimizing raw materials derived from chlorinated solvents, and developing biodegradable backbones to limit environmental accumulation.
Our heavy metal removal agents generate dense, hydrophobic flocs that significantly lower sludge moisture content. This enhances the efficiency of filter presses and evaporators in ZLD systems.
