Engineered to deliver clean water metrics, prevent scaling, and preserve industrial assets across municipal and process industries.
Exploring the chemical mechanisms, surface tension kinetics, and scale dissolution capacities that drive high-efficiency CIP systems.
Industrial scale deposition represents a multi-billion dollar challenge across thermal systems, cooling circuits, and membrane processes. Traditional liquid mineral acids, such as hydrochloric or nitric acids, present high safety risks, transport costs, and localized pitting corrosion hazards. Smedic's Advanced Powder Acid Cleaners leverage customized mixtures of sulfamic acid, citric acid, and proprietary polymeric dispersants to deliver controlled, safe, and highly targeted scale dissolution.
Sulfamic acid ($H_3NSO_3$) acts as a strong monobasic acid, presenting dry, stable, and non-volatile properties at room temperature. When dissolved in water, it fully dissociates to rapidly dissolve carbonate scales and calcium deposits without generating the hazardous fumes associated with volatile acids. The reaction mechanisms are highly efficient:
CaCO₃ + 2H₂NSO₃H → Ca(SO₃NH₂)₂ + H₂O + CO₂↑
Additionally, our formulations integrate organic chelants (such as ethylenediaminetetraacetic acid derivatives and phosphonates) to bind polyvalent metal ions ($Fe^{3+}$, $Al^{3+}$, $Mg^{2+}$) into soluble complexes, preventing the redeposition of secondary scale during Clean-In-Place (CIP) procedures.
Non-hygroscopic powder displaying exceptional descaling performance for calcium and iron deposits. Ideal for heat exchangers, condensers, and high-pressure steam boiler loops.
Advanced film-forming corrosion inhibitors protect copper, carbon steel, and stainless steel metallurgy, reducing corrosion rates to less than 0.5 g/(m²·h) during cleaning.
Optimized pH control ensures thorough organic and inorganic scaling removal without damaging the delicate polyamide active layer of thin-film composite membranes.
A leading provider of environmental protection agents, water treatment formulations, and custom synthesis chemical services.
Smedic Technology is headquartered in Beijing, with wholly-owned production bases located in Hebei, Guizhou, and Shanxi. To ensure robust regional supply and low-cost logistics, we have established over ten OEM partner factories and regional warehousing bases spanning Shandong, Shanxi, Anhui, Guangxi, and Sichuan provinces. Our domestic operations cover over 20 provinces, supporting more than 600 municipal sewage treatment plants and over 1,000 industrial end customers with a cumulative treated volume exceeding 20 million tons per day.
Our academic foundation includes a core technical team of academicians, professors, and senior engineers working within a structured R&D system consisting of one academy, three research institutes, and five production bases. We have been officially recognized as a National High-tech Enterprise and a specialized, refined, unique, and innovative "Little Giant" enterprise by the Ministry of Industry and Information Technology (MIIT).
How Smedic leverages intelligent automation and comprehensive testing protocols to guarantee chemical consistency.
Our production facilities utilize modern horizontal ploughshare mixers integrated with automated gravimetric dosing systems. This ensures homogeneous chemical dispersion of multi-component powder acid cleaners, maintaining a consistent composition ratio across every bag manufactured.
Every incoming batch of raw chemical ingredients (organic acids, specialized corrosion inhibitors, defoamers) undergoes mandatory raw material acceptance testing via ICP-OES and FTIR spectroscopy to ensure strict control over raw material quality.
Powder formulations are highly sensitive to humidity. Smedic employs multi-layer composite packaging materials (PE/PP woven sacks lined with moisture-barrier film sheets) to guarantee a minimum shelf-life of 24 months, even in high-humidity tropical climates.
Our commitment to academic excellence and standardizing the water treatment industry.
Our engineering expertise goes beyond manufacturing; we shape the industry. Smedic has led the drafting of more than ten national and industry standards in China, including standards for composite carbon sources, sodium acetate, and specific biological nitrifying agents. We hold over 60 patents (comprising 40+ invention patents and 20+ utility model patents).
Key academic accomplishments include:
A history of growth, innovation, and technological breakthroughs in the water treatment sector.
Smedic Technology was established in Beijing as a specialized chemical solution provider for municipal sewage treatment, industrial wastewater, and oilfield applications.
Formally recognized as a key national high-tech enterprise following the development of specialized polymer flocculant systems.
Completion of expanded production hubs in Hebei, Shandong, and Guizhou, securing an annual formulation capacity exceeding 1 million tons.
Honored as a National Specialized, Refined, Unique and Innovative Small and Medium-sized Enterprise, reflecting our R&D capabilities in advanced water purification.
Formed a joint venture with the Chengdu Institute of Mineral Comprehensive Utilization, expanding chemical operations to advanced mineral flotation and oilfield recovery systems.
Addressing the critical compliance, packaging, and logistical requirements of international procurement offices.
We provide full OEM support, adjusting key parameters such as active acidity concentrations, pH buffering, particle size, and dye color matching to align with customer branding and application profiles.
Formulations can be packaged in standard 25 kg bags, 500 kg super sacks, or bulk transport containers. Smedic's proximity to major international ports (Tianjin and Qingdao) ensures fast shipping times.
All exported powder acid cleaners conform to global regulatory frameworks, including REACH (EU), OSHA GHS hazard communications, and FDA/NSF listings for food contact cleaning.
Green chemistry developments for zero-liquid discharge (ZLD) systems and next-generation biodegradable organic scale removers.
Global environmental mandates are driving a shift away from persistent EDTA-based chelants and high-phosphorus scale inhibitors. Smedic's R&D platform is focusing on biodegradable organic acid alternatives, such as polyaspartic acid (PASP) and glutamate diacetic acid (GLDA).
These bio-based raw materials display high thermal stability and superior performance in binding calcium and magnesium cations under high pH and salinity conditions, while maintaining rapid biodegradability in natural aquatic ecosystems.
Our developmental pipeline also includes:
Insights into selection, dosing, compatibility, and safety parameters for powder-based industrial acid cleaners.
Powder acid cleaners provide substantial benefits in safety, transport cost, and shelf-life stability. Liquid acids (like HCl or HNO3) are highly corrosive, hazard-classified for freight, and subject to evaporation losses. Dry powders are non-volatile, safe to store, and significantly cheaper to ship globally per unit of active concentration. They are only diluted at the point of use.
Yes. Our cleaners are specifically buffered to operate within a pH range of 2.0 to 3.0 when diluted. This range ensures optimal dissolution of calcium carbonate and iron oxides without hydrolysis of the polyamide membrane barrier, preserving membrane selectivity and flux rate.
For custom OEM/ODM formulations, our standard MOQ is 5 metric tons. Customization, including chemical profiling, laboratory validation, packaging plate-making, and initial production run, generally requires 3 to 4 weeks from approval of specifications.
Our proprietary formulation incorporates organic corrosion inhibitors that form a molecular protective layer on metal surfaces. This layer inhibits charge transfer reactions, shielding carbon steel, copper, and stainless steel from acid attack while allowing the acid to target calcium carbonate and iron scale deposits.
