Our corporate headquarters in Beijing drives continuous R&D innovation, supported by fully owned manufacturing centers in Hebei, Guizhou, and Shanxi, alongside ten OEM partner factories and logistics bases across Shandong, Shanxi, Anhui, Guangxi, and Sichuan. This extensive supply network ensures rapid, reliable logistics and customized chemical formulations for municipal wastewater treatment, industrial process water, mine purification, and oilfield extraction operations globally.
Smedic's integrated technical footprint serves over 600 municipal sewage plants and 1,000 industrial end-users. As high-end purification standards tighten worldwide, particularly regarding Zero Liquid Discharge (ZLD) and advanced Reverse Osmosis (RO) desalinization systems, Smedic continues to engineer highly specialized cleaners and antiscalants to address complex fouling mechanisms and protect valuable membrane assets.
The Global Economic Impact of Membrane Fouling:
Uncontrolled membrane fouling directly increases the Levelized Cost of Water (LCOW) by forcing operational shutdowns for manual cleans, raising energy consumption by up to 30%, and reducing total membrane life by 50% or more. Utilizing highly precise chemical formulations is the single most effective method to mitigate these operational losses.
In localized industrial scenarios—such as high-salinity coal-to-chemical wastewater reclamation, lithium extraction concentration, and oilfield reinjection water cleanup—the composition of feed streams changes constantly. Standard off-the-shelf cleaning solutions often fail to dissolve complex composite scales consisting of calcium carbonate, barium sulfate, silica, and biological EPS (Extracellular Polymeric Substances). Smedic’s specialized formulations are optimized to target specific crystal structures, enabling continuous high flux in the most demanding process environments.
Designed to target carbonate scales (calcium carbonate), sulfate scales (calcium sulfate, barium sulfate), and metal oxides (iron and manganese foulants). Our formulations employ optimized organic acids and mild inorganic acid blends. By reducing the pH of the cleaning bath to 2.0-3.0, mineral salts are converted into highly soluble ionic forms, dissolving the crystal lattice structure without damaging the polyamide active layer of the thin-film composite membranes.
Alkaline formulations operate at pH 11.0-12.0. These agents rely on saponification, emulsification, and chelation to strip away humic substances, proteins, and complex biological biofilms. Smedic incorporates advanced biodegradable chelants (such as GLDA/MGDA) to bind polyvalent cations (calcium and magnesium) that bridge organic matrices, dispersing the foulants from the membrane pores.
Synergy with Coagulants & Flocculants:
Pretreatment carryover is a major source of membrane fouling. Smedic balances the dosing of coagulants like Polyferric Sulfate (PFS) and Polyaluminum Chloride (PAC), along with Anionic/Cationic Polyacrylamides (APAM/CPAM), to minimize downstream membrane footprint while maximizing floc deposition. If carryover does occur, our specialized cleaners are formulated to target and dissolve polymer complexes safely.
Smedic has been recognized as a National High-tech Enterprise, a National Specialized, Refined, Unique and Innovative "Little Giant" Enterprise, and a Hebei Province Green Factory. We hold more than 60 Chinese patents, including over 40 invention patents and 20 utility model patents. Our independently developed technologies, including bio-enhanced denitrification carbon sources and deep multi-nuclear phosphorus removal agents, have won first prize for technological invention from the China Petrochemical Industry Association.
We operate the Hebei Provincial Enterprise Technology Center and the Hebei Provincial Advanced Water Treatment Chemicals Technology Innovation Center, both recognized as Class A R&D institutions. Through active collaborations with Tsinghua University Association of Senior Scientists and Technicians, Shandong University, Beijing University of Technology, Peking University, and Tianjin University, Smedic actively leads the drafting of national and industry chemical safety and performance standards.
For four consecutive years, Smedic has been named the "Leading Brand of Advanced Wastewater Treatment Chemicals" and the "Most Valuable Water Treatment Chemicals Brand" by China Water Network and the E20 Environmental Platform. Our inorganic-organic covalent bond flocculant technology won the 22nd China Patent Award and has been integrated into Belt and Road SME initiatives.
By partnering with prominent water utility groups—including Shouchuang Ecological and Environmental Group, Yangtze River Ecological and Environmental Group, Beijing Enterprises Water Group (BEWG), OriginWater, and China Water Environment Group—we provide centralized procurement and system optimizations that stabilize water production and reduce operating costs.
Treating secondary effluent requires precise biological control. Smedic supplies high-efficiency coagulants (PFS and PAC) and anti-biofouling chemicals that allow membrane systems to process municipal wastewater at high volumes. Our target formulations minimize extracellular polymeric substance (EPS) buildup, helping plants sustain over 20 million tons of daily capacity.
In coal-to-chemical plants, water reuse demands near-total salt separation. This process relies on RO and NF membranes that operate under extreme saturation limits, where calcium sulfate and silica scaling are constant risks. Smedic’s organophosphorus and phosphate-free scale inhibitors are engineered to operate in these environments, preventing crystallization and lowering cleaning frequencies.
In 2024, Smedic established a joint venture with the Chengdu Institute of Mineral Comprehensive Utilization, China Geological Survey. This partnership focuses on heavy metal removal and tailings water recycling. By utilizing tailored non-ionic (NPAM) and anionic (APAM) polyacrylamides, we achieve rapid solids sedimentation, protecting downstream membrane filtration systems from excessive mineral loading.
Produced water reinjection requires effective oil-water separation and biological stabilization. Smedic provides specialized defoamers (polyether and mineral oil-based) along with customized biocide packages that prevent microbial corrosion and organic fouling on high-pressure reinjection membranes.
