As urbanization accelerates and regulatory frameworks around effluent disposal tighten worldwide, the demand for highly efficient, tailored chemical engineering solutions is at an all-time high.
Municipal wastewater treatment is no longer just about meeting basic discharge standards. Modern facilities must optimize their biological nutrient removal (BNR) systems, control foam during aeration, reduce sludge volume, and eliminate trace heavy metals and micro-pollutants—all while managing operating costs and minimizing their carbon footprint. Achieving these concurrent objectives requires a paradigm shift from commodity chemicals to high-precision, customized environmental formulations.
As a premier ODM Municipal Wastewater Treatment Manufacturer and Supplier, Smedic Technology Co., Ltd. delivers high-performance solutions engineered to meet the unique operational and environmental dynamics of municipal operators globally. By integrating advanced academic research with large-scale industrial manufacturing, we bridge the gap between chemical synthesis and field application.
An established leader in advanced wastewater treatment chemicals, providing end-to-end ODM and OEM solutions since 2011.
Established in 2011, Smedic Technology Co., Ltd. is a comprehensive environmental chemical provider integrating research and development, large-scale production, logistics networks, and engineering advisory services. We serve municipal sewage treatment, industrial wastewater, tap water purification, mineral processing, and oilfield extraction sectors globally. Offering more than 80 types of environmental protection agents with an annual production capacity exceeding one million tons, we stand as a powerhouse in the environmental chemical supply chain.
Headquartered in Beijing, Smedic possesses wholly-owned production bases across key industrial regions in China, including Hebei, Guizhou, and Shanxi. Our service footprint is amplified by more than ten joint-venture OEM factories and localized storage facilities in Shandong, Shanxi, Anhui, Guangxi, and Sichuan provinces, covering over 20 provinces across China. Our engineered solutions are deployed at over 600 urban sewage treatment plants and utilized by more than 1,000 industrial end-users, successfully treating more than 20 million tons of wastewater every single day.
Our innovations are backed by academic collaborations, state-recognized patents, and national certifications that confirm our expertise.
Smedic has been recognized as a National High-tech Enterprise and a National Specialized, Refined, Unique and Innovative "Little Giant" Enterprise. Our core R&D system is built upon "one academy, three research institutes, and five bases," housing a technical team led by academic scholars, industry experts, and senior environmental engineers. We hold over sixty Chinese patents, including more than forty invention patents and twenty utility model patents.
We actively collaborate with elite academic institutions, serving as the commercialization partner for the Tsinghua University Association of Senior Scientists and Technicians, Shandong University, Beijing University of Technology, Peking University, and Tianjin University.
How China's raw material abundance, optimized logistics, and industrial infrastructure drive down global procurement costs.
Proximity to key petrochemical and chemical precursors in China allows us to source raw ingredients for Defoamers, Polyacrylamides, and Sodium Acetate at stable costs, mitigating price volatility for our global clients.
Our production lines feature advanced automation and quality control systems. We ensure consistent molecular weight distribution for CPAM/APAM and tight chemical specifications for scale inhibitors and carbon sources.
With warehouses strategically positioned near major maritime ports, we expedite customs clearances and bulk shipments to APAC, Europe, the Americas, and the Middle East, offering optimized shipping schedules.
As a leading Chinese supplier, Smedic leverages an integrated network of joint-venture factories and regional warehousing. Our production capacity of over 1,000,000 tons per year enables us to execute large-scale bulk chemical orders for major municipalities and multi-national distributors. We offer custom container sizes, bulk liquid tankers, flexitanks, and specialized powder packaging formats that align with global handling regulations.
Navigating the complex needs of international water groups, municipalities, and plant operators.
Procuring chemical agents for municipal water treatment requires balancing performance, cost, and compliance. Global engineering procurement managers look for strategic ODM partnerships that offer more than off-the-shelf catalog products. The primary technical considerations include:
Ensuring alignment with global environmental mandates, including EU REACH, US EPA, and local discharge guidelines.
Compliance is critical in environmental chemistry. As an international ODM partner, Smedic ensures that all supplied formulations satisfy the strict safety and toxicity thresholds of importing countries. We provide comprehensive Safety Data Sheets (SDS) in accordance with the Globally Harmonized System (GHS), and all export products are aligned with major regulatory platforms:
Tailoring chemical treatment lines to specific municipal water treatment stages and incoming load properties.
When municipal lines receive high suspended solids (TSS) due to industrial mixed runoff, Smedic’s Polyaluminum Chloride (PAC) and Polyferric Sulfate (PFS) coagulants work together with high molecular weight Anionic Polyacrylamides (APAM) to accelerate floc settlement, reducing downstream organic load.
In cold climate regions or during winter operations, biological nitrification-denitrification processes slow down. Dosing Smedic solid sodium acetate provides a highly bioavailable carbon source, maintaining denitrification kinetics without adding excess sludge mass.
To prevent eutrophication in receiving waters, our Deep Multi-nuclear Phosphorus Removal Agent precipitates soluble phosphates. Combined with specialized defoamers (Silicone or Polyether), it ensures clean discharge without surface foaming.
Over a decade of sustainable growth, technical innovations, and expansion across China and global markets.
How regulatory shifts toward decarbonization and resource recovery are defining the next generation of water chemicals.
The global municipal wastewater sector is transitioning from pollutant removal to resource recovery. This transformation shifts the requirements for auxiliary chemicals in several ways:
Municipal plants are looking to minimize their chemical footprint. Traditional persistent organic polymers are being replaced by biodegradable formulations. Smedic is at the forefront of this trend, developing green polymers and phosphorus-free scale and corrosion inhibitors that prevent secondary water toxicity while maintaining high system uptime.
Rather than relying solely on chemical precipitation, modern facilities leverage bio-augmentation. Dosing specialized nitrifying and denitrifying bacterial agents alongside high-efficiency carbon sources (such as compound sodium acetate) helps maintain stable biological treatment loops, even under fluctuating organic loading conditions.
With landfill space decreasing and sludge disposal fees rising, drying sludge cake to its maximum solids limit is critical. Advanced Inorganic-Organic Covalent Bond Flocculants restructure sludge flocs, facilitating water release and reducing overall disposal volume.
