Pioneering chemical agents engineered for foam suppression, coagulation, and scaling control
Bridging scientific innovations with massive industrial-scale manufacturing
Established in 2011, Smedic Technology Co., Ltd. has evolved into a preeminent, comprehensive environmental protection and chemical solution provider. We seamlessly integrate advanced research & development, state-of-the-art production matrices, and comprehensive technical field services.
Headquartered in Beijing, Smedic maintains direct control over wholly-owned production bases situated in Hebei, Guizhou, Shanxi, and other resource-rich areas. Guizhou, specifically, provides an exceptional geographical and supply-chain advantage for raw phosphate rock processing, ensuring highly competitive, integrated raw-material pathways for our phosphoric acid-based environmental agents.
Our localized network is supported by over 10 strategically placed OEM partner factories and regional warehousing centers across Shandong, Anhui, Guangxi, and Sichuan provinces. This expansive logistics net guarantees consistent lead times and low transit costs for bulk fluid deliveries.
Presently, Smedic coordinates operations spanning more than 20 provinces across China, providing tailored water-treatment compounds, scale inhibitors, defoamers, and biological nutrients to over 600 municipal sewage treatment installations and upwards of 1,000 global industrial manufacturing giants.
How integrated supply chains and natural resource availability ensure global procurement dominance
China hosts some of the world's largest high-grade phosphate rock reserves. Our strategically situated production plant in Guizhou taps directly into this resource layer, bypassing multi-tiered distributor margins. This geographic alignment provides our global partners with long-term cost stability and secure supply streams, even during global chemical market volatility.
Leveraging dual synthesis routes (wet-process purification and thermal-process oxidation), Smedic's production assets feature computerized DCS automation control. We meticulously remove heavy metals (such as arsenic, lead, and cadmium) and fluorine contaminants, producing ultra-pure phosphoric acid solutions that consistently pass rigorous food-grade and electronics-grade standards.
Transporting high-concentration liquid acids demands certified chemical freight logistics. Smedic operates dedicated, ISO-tank and IBC-tote filling stations with immediate access to China's major deepwater marine terminals. Our logistics experts manage international maritime hazardous cargo compliance, ensuring damage-free delivery.
Smedic has been officially recognized as a Chinese National High-Tech Enterprise, a National Specialized, Refined, Unique and Innovative "Little Giant" Enterprise, and a Hebei Province Green Factory. These honors validate our strict adherence to international environmental protocols, minimized carbon emissions, and resource-efficient manufacturing.
Our technology infrastructure is supported by an expert framework of academicians, senior chemical engineers, and professors, working across one academy, three research institutes, and five production bases. We have established joint research laboratories with Tsinghua University Association of Senior Scientists and Technicians, Shandong University, and Beijing University of Technology to continuously advance water-purification chemical technologies.
Furthermore, Smedic acts as a key industrialization partner for academic research originating from Peking University and Tianjin University, transforming patent concepts into scaled chemical processes.
Our intellectual property portfolio includes over 60 Chinese patents, featuring 40+ invention patents and 20+ utility model patents. We have spearheaded the drafting of over 10 national and industry standards for chemical carbon sources, composite coagulants, and bacterial agents.
Precision performance in water treatment, agriculture, metal passivating, and food processing
In biological wastewater treatment plants (WWTPs), microorganisms require balanced inputs of carbon, nitrogen, and phosphorus (typically in a C:N:P ratio of 100:5:1) to support active biomass growth. Phosphoric acid solutions serve as an easily metabolizable, highly bioavailable phosphorus source. In systems treating carbon-rich but phosphorus-deficient industrial wastewater (such as pulp and paper or food processing effluents), adding controlled doses of H₃PO₄ prevents sludge bulking and maintains efficient chemical oxygen demand (COD) removal.
Phosphoric acid is highly effective in metal finishing. It reacts with steel or iron components to form a thin, insoluble layer of iron phosphate ($FePO_4$). This chemical conversion coating passivates the metal substrate, offering excellent rust protection and creating a high-adhesion surface for subsequent painting or powder coating. Additionally, it serves as a key component in chemical polishing baths for aluminum and stainless steel alloys.
In modern drip irrigation and hydroponic farming, phosphoric acid serves a dual purpose. It provides a direct, highly concentrated supply of orthophosphorus, essential for robust crop root development and flowering. Simultaneously, its acidic properties keep drip lines clean by dissolving alkaline calcium carbonate and magnesium salt deposits that build up inside emitters, preventing system clogging.
Phosphoric acid derivatives (specifically organophosphonates such as HEDP, ATMP, and PBTC) serve as the chemical foundation for industrial cooling towers and reverse osmosis (RO) membrane scale inhibitors. By coordinating with divalent scale-forming cations ($Ca^{2+}$, $Mg^{2+}$), these formulations prevent crystalline scale deposition on critical heat-transfer surfaces.
For facilities transitioning to green operations, Smedic provides advanced phosphate-free scale and corrosion inhibitors. These biodegradable formulations prevent scaling and mineral deposition without contributing to phosphorus loading in discharged wastewater, helping plants comply with stringent environmental standards.
Evaluating suppliers through chemical compliance, packaging safety, and quality-assurance systems
Phosphoric acid is classified under UN 1805 (Liquid Phosphoric Acid) Class 8 Corrosive substances. Global buyers must partner with suppliers that comply with international safety frameworks, including:
