Our flagship formulations engineered for the demanding regulatory environment of the Klang Valley and Greater Kuala Lumpur region.
As the industrial hub of Malaysia, the Klang Valley and Kuala Lumpur area host diverse manufacturing industries including electroplating, printed circuit board (PCB) fabrication, automotive assembly, chemical synthesis, and metal finishing. Industrial effluents from these activities are heavily loaded with complexed heavy metals (such as Copper, Nickel, Zinc, Lead, Cadmium, and Chromium) that cannot be precipitated using conventional hydroxide neutralization methods alone.
The Malaysian Department of Environment (DOE) strictly enforces the Environmental Quality Act 1974 and its Environmental Quality (Industrial Effluent) Regulations 2009. Depending on the discharge location (catchment vs. non-catchment areas), plants must comply with Standard A or Standard B. Non-compliance results in severe operational halts, legal prosecution, and environmental damage to vital waterways like the Klang River basin. Smedic’s advanced organosulfur heavy metal removal agents are designed to break chelates and achieve compliance down to sub-ppm levels.
Under local laws, effluents must be strictly controlled:
Smedic agents regularly reduce these to <0.05 mg/L.
In standard wastewater facilities, plant operators use simple pH adjustment (typically by adding sodium hydroxide or calcium hydroxide) to precipitate metals as metal hydroxides. However, this approach faces fundamental physical-chemical limitations:
Different metals precipitate at different pH levels (e.g., Nickel at pH 10.5, Zinc at pH 9.0). If you have a mixed-metal stream, finding a single pH "sweet spot" is chemically impossible. Smedic reagents operate effectively across a broad pH range (3 to 12).
Complexing agents like EDTA, ammonia, and tartrates bind tightly to divalent metal ions, completely preventing standard hydroxide precipitation. Our agents have a stronger binding affinity, displacing the chelators to form stable insoluble salts.
Hydroxide precipitation generates high volumes of loose, gelatinous sludge that is difficult to filter. Smedic heavy metal removal agents produce compact, highly crystalline flocs that settle rapidly and dewater easily, significantly lowering landfill disposal costs.
Smedic heavy metal precipitation agents are based on polymeric sodium organosulfur compounds containing multiple active chelating sites. These active groups carry a strong negative charge that attracts positive metal ions. Once bonded, the linear polymer molecules cross-link to form an insoluble macro-molecular network:
Because the solubility product constant (Ksp) of Smedic metal-chelate complexes is orders of magnitude lower than that of corresponding metal hydroxides, the reaction proceeds quantitatively even at parts-per-billion (ppb) target ranges.

Our independently developed **"Inorganic-Organic Covalent Bond Flocculant and Its Advanced Water Purification Technology"** won the 22nd China Patent Award and the First Prize for Technological Invention from the China Petrochemical Industry Association. We have also drafted over ten national and industry standards for chemical carbon sources, coagulants, and sodium acetate.
A structured guide for factory managers and water engineers in Kuala Lumpur to implement advanced heavy metal recovery systems.
Quantify metal concentrations, identify organic complexes (EDTA, tartrates), and determine pH/conductivity values of the raw waste stream.
Conduct jar testing to determine the optimal stoichiometry. Smedic heavy metal removal agents are typically dosed at a 1:1 to 5:1 ratio relative to metal mass.
Add high-molecular-weight APAM (Anionic Polyacrylamide) to agglomerate micro-precipitates into heavy, rapid-settling flocs.
Run clarified supernatant through sand filters or membrane systems before testing against DOE Standard A or Standard B requirements.
