Municipal and Industrial Water Treatment

Water treatment is a systematic process, and our products are not used in isolation but rather address the entire chain of challenges—from coagulation to discharge—by precisely targeting different water quality nodes.

Coagulant: upgrading from "chemical dosing" to "intelligent flocculation control."

Technical core: Flocculation efficiency depends on the dynamic balance between particle destabilization and bridging aggregation.

Deep Mechanism: Our polyaluminum chloride (PAC) is not a simple chemical compound; its core value lies in its unique Keggin ion structure (e.g., Al₁₃O₄(OH)₂₄(H₂O)₁₂⁷⁺). This highly charged polymerized form can rapidly compress the colloidal double layer through electrostatic neutralization, achieving an efficiency 4 to 5 times higher than traditional aluminum sulfate. When combined with anionic polyacrylamide (PAM), whose long molecular chains act via adsorption and bridging, microflocs are quickly entangled into dense, compact flocs that settle easily.

Technical details: We emphasize the "stepwise dosing" and "gradient mixing" techniques. Specifically, PAC is first added into the raw water pipeline and vigorously mixed (G value > 700 s⁻¹) to rapidly destabilize colloids; then PAM is added in the flocculation tank and gently stirred (G value < 50 s⁻¹) to protect the formed flocs from being broken by hydraulic shear. This combined approach enables stable control of effluent turbidity below 1 NTU in the sedimentation tank, reduces sludge moisture content to 75%–80%, and significantly lowers chemical costs for subsequent sludge dewatering.

Defoamers: From "Physical Defoaming" to "Interfacial Chemical Intervention"

Technical core: In aeration tanks and wastewater containing surfactants, the essence of foam is an elastic film at the gas-liquid interface.

Deep Mechanism: Our polyether-modified silicone defoamer combines low surface tension (<22 mN/m) with high spreading coefficient. Its action mechanism is not simply "breaking" bubbles, but rather enabling hydrophobic particles (such as silicone oil) to rapidly penetrate the foam lamella, reducing local surface tension and accelerating liquid drainage from the film. When the film thickness thins to the critical rupture point (typically less than 10 nm), the bubble collapses spontaneously.

Technical Details: To address the challenge of eliminating microbubbles (diameter <100 μm) in aeration tanks, we utilize emulsion polymerization technology to precisely control the active ingredient particle size between 2–5 μm, enabling accurate attachment to bubble surfaces. The product also features excellent resistance to high temperatures (up to 150°C) and strong alkaline conditions (pH 4–14), ensuring foam suppression lasts 6–8 hours even under high shear and high-salinity industrial wastewater conditions—reducing the need for frequent dosing and lowering per-unit consumption costs.

Activated Carbon: Upgrading from "simple adsorption" to "targeted purification."

Technical core: The effectiveness of activated carbon depends on the synergistic interaction between pore size distribution and surface chemical functional groups.

Deep Mechanism: Our activated carbon products are manufactured through a dual-process approach combining physical activation (steam/CO₂) and chemical activation (phosphoric acid/zinc chloride), precisely controlling the ratio of micropores (<2 nm) to mesopores (2–50 nm). Micropores adsorb small organic molecules (such as precursors of trihalomethanes), while mesopores provide pathways for the diffusion of larger humic substances. Additionally, surface oxidation introduces carboxyl (-COOH) and lactone groups, enabling chemical adsorption of heavy metal ions (e.g., Pb²⁺, Cu²⁺) rather than mere physical enrichment.

Technical Details: In advanced treatment processes (such as ozone-bioactivated carbon, O₃-BAC), we supply extruded crushed activated carbon with high wear resistance (>95%), effectively resisting hydraulic abrasion during backwashing. Through strict control of iodine number (≥1000 mg/g) and methylene blue adsorption value (≥200 mg/g), we ensure stable TOC (total organic carbon) removal efficiency between 80% and 90%, significantly reducing mutagenic activity in treated water.
