KHC-F2001 Technical Breakdown: Dual Acidic Active Sites + Multi-Metal Synergy - How Ozone Catalytic Oxidation Achieves ≥75% COD Removal
I. Carrier Process: Sol-Gel Composite Sintering
KHC-F2001 uses a silica-alumina composite oxide as the carrier, prepared through a sol-gel composite sintering process. Compared with single alumina or conventional carriers, the silica-alumina composite structure offers both chemical stability and thermal stability - the foundation for its long-term stable operation in strongly acidic/alkaline and high-salinity environments.
II. Active Sites: Lewis + Bronsted dual-acidity design
The carrier surface hosts a large number of Lewis acid sites and Bronsted acid sites, forming a dual-acidity catalytic system that promotes reactant adsorption, activation and conversion; multi-metal active components such as manganese, iron and cobalt are further loaded for synergistic catalysis, giving broad-spectrum, highly efficient catalytic oxidation of various organic pollutants. This is the underlying support for the 'rich active sites' advantage.
III. Performance Data at a Glance
Appearance: spherical particles, available sizes 3~5 mm (customizable); specific surface area 300~500 m²/g; bulk density 0.6~0.8 g/cm³; crush strength ≥120 N/particle; attrition rate ≤1%; applicable pH 2~12; service life 5~8 years; ozone decomposition rate ≥95%; COD removal rate ≥75%; color removal rate ≥98%. Compared with conventional ozone oxidation, the COD removal rate increases by more than 30% and ozone utilization by more than 50%.
IV. Field Performance: From Specs to Results
Beyond the specs, real operating conditions matter. In SINOKLE's official landfill leachate case, the raw water COD 20000 mg/L - high salinity, heavy humus and poor biodegradability - enters the KHC-F2001 catalytic oxidation unit after biochemical pretreatment, achieving 99.5% COD removal in the catalytic unit and a stable system effluent below 100 mg/L. The catalyst's mineralization capacity, stability and engineering adaptability are fully verified under such extreme conditions.
V. Integration and Selection
KHC-F2001 can be paired with SINOKLE CDFU cyclonic dissolved air flotation, CDOF ozone oxidation equipment, building a process chain of 'front-end flotation pretreatment + silica-alumina-based ozone catalytic deep oxidation'. For selection, it complements the carbon-based KHC-F1001: choose the silica-alumina-based catalyst for high strength, long-term stability and resistance to complex water quality; choose the carbon-based one for adsorption-driven, cost-sensitive applications.
Viewing the technology chain as a whole: the silica-alumina carrier provides a stable foundation, the dual-acidity sites ensure adsorption and activation efficiency, multi-metal synergy amplifies catalytic activity, hydrophilic modification improves mass transfer, and high-strength forming supports 5~8 years of long life, with regeneration capability lowering whole-life cost. The six dimensions interlock, ultimately delivering stable engineering indicators of 'COD removal ≥75% and color removal ≥98%'.
The six officially summarized technical advantages map one-to-one onto the performance data: high catalytic activity corresponds to ozone decomposition efficiency of 95% or above; super-hydrophilicity corresponds to high mass-transfer efficiency and fast reaction rates; a high specific surface area of 300~500 m²/g corresponds to uniform distribution of active sites; high stability corresponds to acid/alkali and high-temperature resistance without long-term loss or pulverization; rich active sites correspond to the synergy of Lewis and Bronsted acid sites; long service life corresponds to crush strength ≥120 N/particle, wear and scouring resistance, and regenerability.
An easily overlooked but crucial point is super-hydrophilicity: the catalyst surface is optimized for wettability, so it contacts the water phase fully, ozone and pollutants transfer more efficiently, the catalytic oxidation reaction is faster, and treatment is more stable. Especially in continuous high-load operation, mass-transfer efficiency directly determines the reactor's actual treatment capacity.
Tearing the technology down to its essence, the logic of KHC-F2001 is clear: the silica-alumina carrier solves the 'withstanding' problem, the dual-acidity sites and multi-metal solve the 'driving the reaction' problem, and high-strength forming plus regenerability solve the 'lasting long' problem. When all three are answered well, COD removal ≥75%, color removal ≥98% and a 5~8 year service life follow naturally.
For engineering and technical personnel, the value of KHC-F2001 lies in predictable parameters: specific surface area, strength, attrition rate, pH range and service life all come with explicit specifications, so process design, operation and maintenance, and cost estimation can all be grounded in data.
We hope this breakdown helps with your selection.
The combination of hydrophilic optimization and high-strength forming also keeps it delivering stable output through 24 hours of continuous high-load operation.
