Explore our premium range of scale inhibitors, defoamers, coagulants, and biological treatment agents engineered for municipal and industrial applications.
Unlocking information gain to bridge the gap between compliance demands and technological operational efficiency.
Municipal sewage treatment is undergoing a fundamental paradigm shift globally. The transition from simple organic matter removal (COD/BOD control) to deep nutrient removal (nitrogen, phosphorus, refractory trace pollutants, and heavy metals) requires an integrated approach to chemical agent optimization. Buyers and plant operators are no longer merely sourcing bulk commodities; they seek tailored ODM formulations that adapt to dynamic inflow profiles, seasonal temperature fluctuations, and increasingly stringent discharge standards, such as China's First-Class A and near-surface Class IV limits, as well as European Directive equivalents.
To address these evolving demands, Smedic Technology Co., Ltd. positions itself as a premier partner. Established in 2011, we integrate R&D, production, sales, and engineering-related technical services to provide custom-designed chemical programs that optimize biological wastewater treatment stages, membrane filtration units, and sludge dewatering systems.
Our comprehensive operations cover the entire Chinese domestic market and extend to global supply routes, supported by robust logistics and regional warehousing:
As a global hub for chemical synthesis, China offers unparalleled benefits for municipal wastewater treatment supply chains. Smedic leverages these structural advantages to provide reliable, high-purity, and cost-effective formulations to global municipal operators and distributors.
Our factory operations benefit from direct vertical integration with primary chemical syntheses. For instance, in our production of Pure Solid Sodium Acetate and Composite Carbon Sources, we utilize high-grade raw materials sourced from closely monitored domestic production networks. This ensures that the organic carbon availability remains consistently high (up to 99% purity for solid grades), which directly translates to a faster denitrification rate in anaerobic biological treatment stages. Similarly, our production lines for Polyaluminum Chloride (PAC) and Polyferric Sulfate (PFS) utilize state-of-the-art spray drying technology, yielding coagulants with uniform particle size distributions, high basicity, and exceptional solubility.
Modern municipal wastewater treatment plants (WWTPs) face fluctuating organic loading rates, toxic shock loads from industrial inputs, and cold-weather nitrification drops. Smedic designs multi-layered chemical solutions that target critical bottlenecks throughout the treatment sequence:
In low C/N ratio influent, denitrification is severely carbon-limited. Smedic's biological carbon sources are specifically formulated to support the growth of denitrifying bacteria, shifting the microbial community structure toward highly efficient species. Our liquid bio-enhanced carbon sources offer a COD equivalent ranging from 300,000 to 1,000,000 mg/L, optimizing denitrification rates at temperatures as low as 8°C.
Through our independently developed Inorganic-Organic Covalent Bond Flocculant (which won the 22nd China Patent Award), we combine the rapid charge-neutralization capabilities of polymetal complexes with the bridging effects of high molecular weight organic polymers. This dual action facilitates the formation of dense, fast-settling flocs, allowing municipal plants to achieve deep phosphorus removal (TP < 0.3 mg/L) without generating excessive chemical sludge.
Surfactant-rich municipal and industrial wastewater streams frequently suffer from excessive foaming in aeration basins and digestors. Smedic's range of Polyether Defoamers and Organic Silicone Defoamers provides rapid bubble-bursting action and long-lasting foam suppression without inhibiting oxygen transfer efficiency or harming active microbial consortia.
International buyers of municipal sewage treatment chemicals must navigate complex compliance frameworks, ocean freight logistics, and strict shelf-life requirements. Smedic operates a comprehensive supply network that ensures seamless delivery across borders. With warehouses strategically located near key major shipping ports, we facilitate rapid transit to European, Southeast Asian, Middle Eastern, and American destinations.
Our ODM capabilities extend to custom packaging—ranging from 25kg bags and 1000L IBC totes to bulk liquid tankers—and precise chemical formulation adjustments to match regional temperature profiles and localized regulatory criteria (such as EU REACH registration and NSF/ANSI certifications).
A testament to our academic depth, continuous technological innovation, and industry authority.
Smedic has built a robust technology commercialization platform centered around one academy, three research institutes, and five bases. We host an expert workstation in collaboration with the Tsinghua University Association of Senior Scientists and Technicians, and maintain joint R&D laboratories with Shandong University and Beijing University of Technology. Furthermore, we serve as a key commercialization partner for the industry-academia-research achievements of Peking University and Tianjin University.
We have led the drafting of over ten national and industry standards in China, including those for composite carbon sources, composite coagulants, sodium acetate, and nitrifying and denitrifying bacterial agents. Our proprietary technologies have won multiple prestigious accolades, including the Hebei Province Science and Technology Progress Award and the First Prize for Technological Invention from the China Petrochemical Industry Association.
We hold over sixty Chinese patents, including more than forty invention patents and over twenty utility model patents. We have been recognized as the "Leading Brand of Advanced Wastewater Treatment Chemicals" and the "Most Valuable Water Treatment Chemicals Brand" by China Water Network and the E20 Environmental Platform for four consecutive years.
