Explore our specialized, high-performance OEM & ODM water treatment chemical systems designed to meet rigorous discharge standards and improve solid-liquid separation efficiency.
Established in 2011, Smedic Technology Co., Ltd. stands as a premier comprehensive solution provider in environmental protection agents, integrating advanced research & development, large-scale chemical production, global supply logistics, and specialized field engineering services. We focus on addressing complex liquid-solid separation, heavy metal chelation, and chemical clarification challenges for municipal sewer utilities, heavy manufacturing plants, mining facilities, and oil & gas extraction sites.
As a national recognized authority in water treatment chemistry, Smedic manufactures over 80 distinct environmental protection chemicals with a consolidated annual production capacity exceeding 1,000,000 tons. Our operation encompasses multiple proprietary, vertically integrated production bases in Hebei, Guizhou, and Shanxi, supported by a network of over ten OEM partner facilities and strategic logistics centers across China's major industrial corridors (Shandong, Shanxi, Anhui, Guangxi, Sichuan).
Modern wastewater treatment is no longer just about settling suspended solids. Today's global chemical landscape demands high kinetic efficiency, compliance with stringent environmental directives, and low carbon footprints.
Regulatory frameworks such as the EU Water Framework Directive, the United States EPA Clean Water Act, and China’s Class A discharge benchmarks demand near-zero levels of phosphorus, toxic heavy metals (such as lead, cadmium, and arsenic), and trace organic elements. Standard primary coagulants struggle to achieve these limits without chemical modification and process optimization.
Disposal costs for chemical sludge continue to escalate worldwide. Traditional low-charge inorganic coagulants generate large quantities of hydrated sludge, driving up dewatering and transportation costs. Modern industrial operations require highly charged polymeric coagulants that optimize floc structure, reducing sludge volume index (SVI) and water content.
Wastewater matrices are increasingly complex, containing refractory organic matter, emulsified hydrocarbons, micro-pollutants, and highly variable pH ranges. An off-the-shelf coagulant cannot resolve all variables. Custom ODM chemical synthesis, engineered to match the specific zeta potential of incoming solids, is necessary to achieve consistent water clarity.
To reduce operational expenditures, water treatment systems must optimize the balance between coagulants, polymer aids, and pH neutralizers. Smedic's integrated formulations (such as our hybrid inorganic-organic coagulants) deliver high flocculation speed and settling velocity, minimizing overall chemical dosage requirements and infrastructure footprints.
Smedic Technology operates a sophisticated research network led by senior chemists, water engineering experts, and academic consultants. We have built an R&D system centered around **one academy, three research institutes, and five regional testing bases**. This is anchored by three provincial-level platforms: the Hebei Provincial Enterprise Technology Center, the Hebei Provincial Advanced Water Treatment Chemicals Technology Innovation Center, and the Cangzhou Water Treatment Engineering Technology Research Center.
To accelerate innovation, Smedic maintains an expert workstation with the **Tsinghua University Association of Senior Scientists and Technicians**, alongside joint R&D laboratories with **Shandong University** and **Beijing University of Technology**. Additionally, we act as a commercialization partner for the research achievements of **Peking University** and **Tianjin University**, translating lab discoveries into industrial-scale water treatment products.
Our patent portfolio comprises over **sixty Chinese patents**, including more than **forty invention patents** and over twenty utility model patents. Smedic has led the drafting of over ten national and industry standards in China, defining technical specifications for composite carbon sources, composite coagulants, sodium acetate, and nitrifying and denitrifying bacterial agents.
Coagulation destabilizes colloidal suspensions through charge neutralization, polymer bridging, and sweep-floc precipitation. Smedic's ODM service optimizes these processes by customizing the molecular weight, charge density, and basicity of our polymers.

From deep mines in the Americas to petrochemical hubs in the Middle East and municipal plants in APAC, Smedic customizes coagulant chemistry to local conditions.
Our solutions target municipal nutrient removal (specifically phosphorus limits down to 0.1 mg/L) and low-temperature flocculation. The bio-enhanced carbon sources improve nitrogen removal in winter, while our composite coagulants improve settling in primary and secondary clarifiers, protecting downstream membranes.
Emulsified oil, complex surfactants, and high COD challenge standard treatment systems. Smedic’s silicone and polyether defoamers, combined with our organic-inorganic hybrid coagulants, break oils and emulsions, allowing flotation systems to achieve high efficiency.
Our high-molecular-weight Anionic and Non-Ionic Polyacrylamides (APAM & NPAM) assist in solid-liquid separation for mineral processing. By partnering with the Chengdu Institute of Mineral Comprehensive Utilization, we deliver tailing clarification products that improve water recovery rates.
High concentration metal ions and fluoride in metallurgical and semiconductor wastewater require targeted treatment. Our Specialized Fluoride Removal Agents and Heavy Metal Chelating Agents precipitate trace metal complexes under challenging conditions.
Our organophosphorus and phosphate-free scale inhibitors protect reverse osmosis membranes and cooling towers from fouling, helping prolong system lifespan and reduce acid cleanings.
In a volatile chemical market, supply security is essential. Smedic maintains high supply reliability through integrated manufacturing bases and strategic raw material procurement.
Our production facilities in Hebei, Guizhou, and Shanxi utilize automated synthesis loops to ensure batch-to-batch consistency. Operating at an annual output level exceeding 1,000,000 tons, we secure bulk precursor raw materials (including liquid chlorine, ferrous sulfate, and acrylic acid) directly from upstream suppliers. This integration buffers global clients against raw material price shocks and ensures reliable lead times.
For international shipments, Smedic operates dedicated storage facilities near Tianjin, Qingdao, and Shanghai ports. This logistics footprint supports quick dispatch for containerized liquid or powder chemicals, meeting the timelines of operations worldwide.
