Engineered formulations offering maximum efficiency, precise COD reduction, foam suppression, and scale inhibition for municipal sewage and industrial filtration.
Global urbanization, rapid industrial growth, and increasingly stringent environmental regulations have catalyzed a paradigm shift in how municipal wastewater is handled. Modern municipal water filtration is no longer limited to simple mechanical separation. Instead, it relies on complex chemical-biological filtration synergies to remove trace impurities, manage chemical oxygen demand (COD), eliminate heavy metals, and neutralize phosphates. Finding reliable municipal water filtration manufacturers who can produce top-grade coagulants, high-performance flocculants, and advanced biological enhancers at a massive industrial scale is critical for cities and environmental projects worldwide.

Our commitment to technical innovation is backed by a portfolio of over sixty Chinese patents, including more than forty invention patents and over twenty utility model patents. We have drafted more than ten national and industry standards for composite carbon sources, composite coagulants, sodium acetate, and specialized nitrifying/denitrifying bacterial agents.
Our bio-enhanced denitrification carbon source and deep multi-nuclear phosphorus removal agent have passed rigorous evaluations by the Science and Technology Department of Hebei Province, earning recognition as "internationally advanced." Furthermore, our "Active Oxygen Compound Disinfectant" has been recognized as a National Construction Industry Scientific and Technological Achievement Promotion Project by the Ministry of Housing and Urban-Rural Development.
Over a decade of rapid scaling, technical breakthroughs, and national awards in water science.
How Smedic agents target specific chemical challenges inside treatment plants globally.
During winter months or in cold climates, nitrifying bacteria require external carbon sources. Smedic pure solid sodium acetate and composite carbon sources serve as highly bioavailable energy sources for denitrifying bacteria. This boosts nitrate-nitrogen to nitrogen gas conversion rates, even under high-hydraulic-load conditions.
In highly regulated watersheds, standard biological treatment fails to meet low phosphorus limits. Smedic's patented deep multi-nuclear phosphorus removal agent complexes suspended, colloidal, and dissolved phosphorus into heavy flocs that settle rapidly, reducing total phosphorus (TP) to below 0.1 mg/L.
Processing thousands of tons of municipal sludge requires heavy-duty flocculants. Using Smedic cationic polyacrylamide (CPAM) with high charge density alters the surface charges of sludge particles. This releases bound water and creates large, shear-resistant flocs that optimize belt filter presses, centrifuge dewatering, and drying efficiency.
For municipal operators globally, supply chain disruptions can lead to compliance failures or operational shutdowns. Smedic mitigates these risks through a vertically integrated manufacturing structure. By maintaining massive production bases across multiple provinces (Hebei, Guizhou, Shanxi), we avoid raw material bottlenecks and keep prices stable.
We source raw chemical feedstocks directly from local primary producers. Our regional warehouses in Shandong, Shanxi, Anhui, Guangxi, and Sichuan provide redundant inventory storage. This ensures that even during seasonal logistics constraints, our clients receive orders on schedule. With a total annual capacity exceeding 1 million tons, Smedic can ramp up production to meet sudden demand increases from new municipal expansions.

Adapting chemical engineering to support eco-friendly, circular-economy municipal water filtration.
Our R&D team is developing scale and corrosion inhibitors that do not contain phosphates. This prevents secondary eutrophication and complies with the strictest environmental discharge limits in Europe and North America.
By pairing our chemical agents with real-time turbidity, COD, and phosphorus sensors, Smedic helps operators build automated dosing systems. This cuts overall chemical usage by up to 25% while maintaining discharge compliance.
We are researching methods to recover usable phosphorus from chemical sludges. This helps municipal sewage facilities transition from simple waste disposal sites into active resource recovery hubs.
How Smedic translates Chinese industrial capacity into regulatory compliance and engineering support worldwide.
Exporting water chemicals globally requires meeting strict international standards. Smedic maintains full certification for ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health and Safety). We also ensure that our export products comply with regional frameworks such as EU REACH regulations and US EPA guidelines.
Our role in drafting over ten national and industry standards in China—including standards for composite carbon sources, composite coagulants, and sodium acetate—demonstrates our technical authority. Beyond manufacturing, Smedic sends field engineers directly to municipal wastewater plants to conduct beaker tests, optimize dosing locations, and calibrate automated dosing pumps for our clients.
