Explore our premium selection of advanced industrial coagulants, scale inhibitors, and specialty treatment compounds manufactured to meet stringent global standards.
Polyaluminum Chloride (PAC) stands as the cornerstone of contemporary water clarification. Unlike traditional monomeric metal salts such as alum or ferric chloride, PAC is an inorganic polymer characterized by high charge neutralization capability and strong polymeric bridging structures.
By optimizing the **Basicity Ratio** (the degree of hydroxyl neutralization relative to aluminum), advanced PAC formulations can drastically accelerate floc formation, improve sedimentation velocities, and lower residual heavy metal concentrations in treated water matrices.
At Smedic Technology, we leverage proprietary spray-drying technologies to synthesize PAC with precise $Al_2O_3$ concentrations ranging from 28% to 30%, satisfying both municipal potable water benchmarks (NSF/ANSI Standard 60 compliant) and complex industrial wastewater purification demands.
Charge Neutralization: Polycationic aluminum species (e.g., $Al_{13}$ and $Al_{30}$ keggin structures) rapidly destabilize negatively charged colloidal suspensions.
High molecular weight polymeric chains capture suspended silts, microplastics, and dissolved organic carbon (DOC), creating robust flocs resilient to shear stress.
Founded in 2011, Smedic Technology is a leading environmental protection chemical manufacturer integrating scientific research, large-scale production, global export logistics, and technical consulting.
Our corporate headquarters is in Beijing, with wholly-owned manufacturing bases operational across **Hebei, Guizhou, and Shanxi**. Backed by over a dozen OEM partner factories and regional hubs, our integrated logistics framework spans 20+ provinces in China, serving more than 600 municipal sewage treatment plants and over 1,000 industrial end-users daily.
How advanced manufacturing, industrial clusters, and strict quality assurance make Chinese polyaluminum chloride the premier choice for global buyers.
Traditional drum-dried PAC is prone to high insoluble residue and slow dissolution rates. Our spray-drying tower uses high-pressure atomization to produce uniform, fine micro-granules with 99.8% water solubility, ensuring zero clogging in dosing pumps.
By engineering a basicity ratio between 50% and 90%, our PAC coagulants minimize the reduction of effluent pH. This dramatically decreases the need for supplementary alkali dosing (such as sodium hydroxide or lime), lowering overall process costs.
Our raw material purification process selectively treats bauxite and synthetic hydrochloric acid, reducing heavy metal content (e.g., Lead, Arsenic, Cadmium) to levels far below domestic and international standards, protecting biological downstream filters.
sourcing water chemicals directly from Chinese factories yields massive strategic benefits:
From extreme industrial pollutants to municipal drinking water pipelines, our customized PAC formulas deliver stable turbidity reduction across global landscapes.
Our NSF-compliant white PAC contains minimal iron content, preventing color degradation in city water mains. It works efficiently in cold climates (down to 2°C) where traditional metal salt coagulants struggle to form flocs.
Textile printing, leather tanning, and petrochemical effluents carry high COD, heavy metals, and emulsified oils. Smedic PAC acts as a primary clarifying agent, breaking emulsion interfaces and encapsulating refractory organic loads.
Designed for coal washings, copper concentrate thickening, and tailing ponds management. Accelerates back-water recycling loops to help mines conform with local zero-liquid-discharge (ZLD) regulations.
Smedic Technology is not just a manufacturer; we are a nationally recognized Specialized, Refined, Unique and Innovative "Little Giant" Enterprise in China. This elite tier of recognition validates our independent development of high-tier environmental chemical reagents.
Our core R&D system operates through **one academy, three research institutes, and five production bases**, hosting expert workstations in collaboration with the **Tsinghua University Association of Senior Scientists and Technicians**. We also partner with Shandong University, Beijing University of Technology, and Peking University to commercialize new-generation water purification technology.
With over 60 Chinese patents (including 40+ invention patents), Smedic has actively drafted over 10 national industry standards governing carbon sources, composite coagulants, and biological agents.
Our journey as a specialized high-performance water treatment chemical provider from 2011 to today.
Smedic Technology was founded, focusing on R&D of eco-friendly polymers.
Established a comprehensive municipal wastewater treatment chemical portfolio.
Established Guiyang advanced water treatment chemical production base to serve Southwest China.
Production hubs in Hebei, Shandong, and Guizhou expanded, exceeding 1 million tons annual capacity.
Officially recognized as a National Specialized, Refined, Unique and Innovative "Little Giant" Enterprise.
Awarded National Intellectual Property Advantage Enterprise with over 60 patents filed.
How we satisfy the rigorous demands of international engineering firms, chemical distributors, and public utilities.
We perform incoming ICP-MS metal testing on every batch of raw hydrochloric acid and bauxite. This maintains an iron oxide content below 0.3% for white PAC and strictly limits heavy metals (Cd, Pb, As, Cr, Hg) to trace parts-per-billion levels.
Different industrial processes demand distinct chemical profiles. We custom synthesize PAC with basicity ratios ranging from low (50-60%) for highly alkaline organic wastewaters, to high (80-90%) for acidic surface waters.
Standard packaging includes 25kg PP/PE woven bags, 1000kg bulk super sacks, or customized private-label OEM bags. Our logistics depots handle sea freight container shipping, flat rack container delivery, and ISO tank transport.
Our lead chemical engineers answer the most pressing technical questions regarding coagulant selection, usage, and optimization.
Our broader family of water treatment chemicals, including advanced defoamers, scale inhibitors, and organic/inorganic polymer blends.
