Industrial grade flocculants, metal precipitants, and inhibitors produced to strict international standards.
Rapid industrialization and stringent environmental protection directives command high efficiency from modern sewage purification agents. As a premier OEM wastewater chemicals manufacturer and exporter, Smedic Technology Co., Ltd. leads in synthesizing and scaling complex macromolecular solutions tailored to municipal and industrial demands. Since 2011, we have engineered custom polymer structures and inorganic coagulants designed to lower Total Suspended Solids (TSS), chemical oxygen demand (COD), and nitrogen concentrations under extreme hydraulic loads.
Through our comprehensive R&D center and joint laboratories with Tsinghua University and Shandong University, we bridge the gap between bench-scale polymer design and million-ton industrial production. In wastewater chemistry, a minor shift in ionic charge density or molecular weight distribution yields significant changes in dewatering velocities and filter cake moisture levels. Smedic's technology maps molecular structures directly to raw effluent composition for unmatched floc strength and filtration speed.
Developing eco-friendly formulations to improve processing metrics while reducing chemical footprints.
Smedic Technology focuses on three technological axes: high-molecular-weight anionic polyacrylamide, metal-chelating polymers for heavy metal separation, and biological carbon additives. The technical roadmap highlights our focus on lower carbon footprint alternatives, including eco-friendly raw-material synthesis and biodegradable polycarboxylate scales to replace traditional organophosphorus options.
| Chemical Agent Line | Active Mechanism | Target Pollutants | Environmental & Performance Metrics |
|---|---|---|---|
| Anionic Polyacrylamide (APAM) | Bridging, charge neutralization, micro-floc formation | Suspended solids, mineral clay tailings, process water | Molecular Weight: 8–25 Million Dalton; Hydrolysis degree customized. |
| Cationic Polyacrylamide (CPAM) | Charge neutralization, sludge particle aggregation | Biological municipal sludge, organic waste liquids | Ionicity: 10%–80% active sites; reduces moisture in filter cake by 15%. |
| Heavy Metal Precipitants | Multi-dentate ligand complexation, macromolecular precipitation | Copper, Nickel, Zinc, Lead, Cadmium complexes | Reduces ionic metallic species to < 0.1 mg/L (compliant with EPA guidelines). |
| Fluoride Removal Agent | Synergistic adsorption and isomorphic substitution | Inorganic fluoride anions (F-) | Low dose treatment capable of driving F- limits below 1.0 ppm. |
| RO Membrane Scale Inhibitors | Crystal lattice distortion, dispersion, threshold inhibition | Calcium carbonate, Calcium sulfate, Barium sulfate scales | Extends membrane lifespans by up to 40% under high LSI conditions. |

Providing custom chemical options for industrial sectors requiring efficient water management.
Smedic integrates the entire production cycle from monomer synthesis (Acrylamide) to finished granular polymers. By managing our raw material supply chain, we stabilize production costs and prevent supply disruptions during market fluctuations. Our automated production facilities employ advanced DCS systems to manage reactor profiles, reducing batch-to-batch variations to below 3%.
This automated foundation supports our OEM partners, allowing us to supply custom products with short lead times. We offer custom packaging, custom product parameter adjustments, and flexible batch sizing to meet distinct procurement requirements.
Navigating chemical import regulations, logistics pathways, and quality assurance processes.
Answers to common technical, logistics, and chemistry questions from wastewater operators.
Optimal CPAM ionicity selection depends on the charge density of the sludge. High-organic biological sludge from municipal digesters typically requires moderate to high ionicity (40% to 70%) to achieve charge neutralization. Industrial inorganic sludges respond better to low-ionicity formulations. Smedic provides beaker-scale jar tests to determine the optimal dosage curve and select the appropriate ionicity range.
Granular polyacrylamides have a shelf life of up to 24 months when stored in sealed, moisture-proof bags under cool, dry conditions. Liquid polymer emulsions typically have a shorter shelf life of 6 months due to phase separation risks, and should be kept protected from extreme temperatures. We incorporate specialized stabilizers in our liquid emulsions to help prevent early separation and settling.
Smedic's fluoride removal agent uses synergistic adsorption and isomorphic substitution, precipitating dissolved fluoride ions into insoluble complexes. This chemical precipitation mechanism achieves residual F- concentrations below 1.0 ppm without the high sludge volumes associated with calcium chloride processes.
Yes. Smedic supports OEM clients with custom packaging options, including 25kg multi-wall bags, bulk super-sacks, and liquid intermediate bulk containers (IBCs). We also provide custom labeling, localized multi-language SDS documentation, and neutral packaging options.
