Heavy duty industrial agents designed to comply with local discharge standards, targeting high concentrations of toxic heavy metals, suspension loads, and chemical oxygen demand.
Pakistan's rapidly growing industrial sector, centered in key regions such as Karachi (Korangi, Landhi, and F.B. Area), Lahore, Sialkot, Faisalabad, and Gujranwala, faces intense environmental pressures. The discharge of untreated industrial wastewater containing toxic heavy metals has posed a critical threat to groundwater tables and ecological systems. Sectors like leather tanning in Kasur and Sialkot discharge significant quantities of Chromium (Cr-III and Cr-VI), while textile dyeing, metal finishing, and petrochemical processing release elevated concentrations of Lead (Pb), Cadmium (Cd), Nickel (Ni), and Copper (Cu).
To address this crisis, the Pakistan Environmental Protection Agency (Pak-EPA) has enforced the National Environmental Quality Standards (NEQS) for municipal and liquid industrial effluents. Under these regulations, strict thresholds have been set for metal discharges (e.g., Chromium < 1.0 mg/L, Lead < 0.5 mg/L). Meeting these criteria requires state-of-the-art chemical precipitation agents that can effectively chelate, coagulate, and sediment metallic ions under dynamic pH environments.
Understanding the molecular dynamics of heavy metal removal is key to selecting the right chemical formulation for industrial purification plants.
Unlike traditional sodium hydroxide or lime precipitation, Smedic’s Heavy Metal Removal Agents contain high-density polymeric dithiocarbamate (DTC) groups that form strong multi-dentate complexes with metallic ions, achieving stable precipitate structures that do not easily re-dissolve.
Works synergistically with Polyaluminum Chloride (PAC) and Polyacrylamide (PAM) to accelerate flocculation. The large molecular weight of the co-precipitate shortens settling time from hours to minutes, ensuring minimal footprint in ETP (Effluent Treatment Plant) operations.
Our organosulfur reagents yield low-volume, highly compacted sludge that passes EPA Toxicity Characteristic Leaching Procedure (TCLP) tests. This reduces post-treatment hazardous waste disposal costs significantly for local Pakistani factories.
A comprehensive environmental protection agent solution provider integrating R&D, advanced manufacturing, and deep logistics connectivity to Pakistan.
Established in 2011, Smedic Technology Co., Ltd. has grown into a leading comprehensive solution provider specialized in environmental protection agents. We integrate R&D, production, sales, and engineering-related technical services to deliver bespoke water purification strategies globally.
Our corporate headquarters is located in Beijing, with wholly-owned production bases situated in Hebei, Guizhou, Shanxi, and other regions, supplemented by over ten OEM partner factories and regional warehousing hubs. With an annual production capacity exceeding 1 million tons and over 80 environmental protection products in our portfolio, we support projects containing more than 600 urban sewage treatment plants and over 1,000 industrial wastewater clients worldwide.
Recognized as a National Specialized, Refined, Unique and Innovative "Little Giant" Enterprise, Smedic possesses robust intellectual property portfolios to back up our technical claims.
We have been granted over sixty Chinese patents, including more than forty invention patents and over twenty utility model patents. We have led the drafting of more than ten national and industry standards. Our core technical team consists of academicians, experts, and senior engineers collaborating with top-tier academic institutes like Tsinghua University, Shandong University, and Beijing University of Technology.
Our heavy metal removal agent ranges are specifically tailored to meet the dynamic needs of various Pakistani manufacturing zones.
Targeting the complex organic matrices of leather waste stream effluents. Smedic's agents break organic-chromium complexes, reducing Chromium (Cr-VI/Cr-III) to levels below 0.5 ppm, easily passing regional NEQS standards.
Heavy metals such as Copper and Zinc are widely used in textile dye catalysts. Smedic agents sequester these metals concurrently with primary dye decanting, achieving dual-purpose decolorization and metal settling.
Acid washes and passivation techniques in surgical steel manufacturing result in high Nickel and Iron discharges. Smedic formulation chelates these metals in acidic streams without requiring extreme alkali neutralization.
Tracing our path from a local environmental supplier to a global technical authority in industrial water solutions.
Smedic Technology Co., Ltd. was established to specialize in water treatment and oilfield chemical agents.
Established a complete municipal wastewater treatment portfolio, expanding services to regional sewage treatment hubs.
Officially recognized as a Key National High-Tech Enterprise, marking a significant milestone in intellectual capability.
Major expansion across multiple production bases in Hebei, Shandong, and Guizhou, exceeding 1 million tons in cumulative annual output capacity.
Awarded the prestigious "National Specialized, Refined, Unique and Innovative Small and Medium-sized Enterprise" status.
Recognized as a National Intellectual Property Advantage Enterprise with over sixty patents under management.
Formed joint ventures with the Chengdu Institute of Mineral Comprehensive Utilization and China Geological Survey to advance raw mineral processing reagents globally.
Optimizing operations through highly specialized organic defoamers, scale inhibitors, and inorganic coagulant matrices.
Adapting to circular economy mandates and sustainable industrial frameworks across South Asia.
Our upcoming generation of chelants uses highly selective molecular patterns. They isolate heavy metals without stripping valuable non-hazardous salts like calcium and sodium, preventing unnecessary chemical expenditure in brackish effluent setups.
To eliminate concerns regarding secondary amine pollution, our R&D center is developing botanical-based polymeric chelating groups. These formulations decompose naturally into harmless components after metal capture and sludge collection.
We are tailoring our heavy metal removal agents to align seamlessly with reverse osmosis (RO) and multi-effect evaporator (MEE) pretreatment loops, minimizing scale formation on membrane units while guaranteeing pure distillate recoveries.
Working with global suppliers requires absolute certainty in logistics and post-purchase laboratory support. Recognizing the specific logistics issues faced by Pakistani importers, Smedic offers streamlined supply mechanisms.
1. Customs Clearance and Documentation: Smedic provides comprehensive paperwork, including SGS Inspection Reports, SDS conforming to GHS standards, and Certificate of Analysis (COA) to guarantee quick clearing at Karachi Port (KICT/PICT).
