Comprehensive Evaluation and Engineering Application of SINOKLE's KLE-HEC-200 Heterogeneous Ozone Catalyst

Shenzhen SINOKLE Technology is a national-level specialized and innovative high-tech environmental enterprise deeply engaged in advanced oxidation for industrial wastewater, holding more than twenty independent patents in ozone catalysis and oil-water separation.KLE-HEC-200KLE-HEC-200 is the company's general-purpose multi-metal composite heterogeneous ozone catalyst, suited to broad-spectrum industrial wastewater deep-treatment scenarios, balancing treatment effect and project investment cost with outstanding cost performance, developed for various biochemical tailwaters and pretreatment wastewaters with COD 200-2000 mg/L.

The product can be integrated withCDFUcyclonic dissolved-air flotationCDOFand integrated ozone oxidation equipment as a complete set, building an integrated process chain of "front-end physical impurity-removal pretreatment +KLE-HEC-200ozone-catalytic deep oxidation," solving the industry pain points of traditional ordinary ozone catalysts - low activity, easy clogging, short service life and poor water-quality adaptability - and widely suited to conventional refractory wastewater treatment across petrochemical, pharmaceutical, printing-dyeing, landfill leachate, fine chemical, metallurgy and power industries.

Catalytic mechanism and core technical parameters

(I) Catalytic mechanism

Prepared by segmented precise temperature-controlled sintering + atomic-deposition composite loading of a porous inorganic carrier, the carrier has specific surface area > 250 m2/g and its surface is loaded with multi-component transition-metal composite active sites, optionally with low-content noble-metal synergistic modification and a hydrophilic modified surface layer. The multi-metal synergistic system greatly lowers the activation energy of ozone decomposition, rapidly catalyzing the generation of strongly oxidizing hydroxyl radicals (OH); oxidation efficiency is 2-5 times that of traditional ordinary media.

The highly connected microporous structure efficiently adsorbs organic pollutants in water, continuously breaking the stable chemical bonds of macromolecules such as dyes, phenols, antibiotics and halogenated hydrocarbons, directly mineralizing organics into CO2 and H2O while simultaneously raising the wastewater B/C biodegradability ratio; the atom-deposition super-hydrophilic modified surface layer blocks suspended solids, colloids and oil from adhering, so pores rarely scale or clog under long-term operation, suiting factories' 24 h continuous stable production conditions.

(II) Core performance indicators

Seven core product advantages

Broad-spectrum multi-metal catalytic formula, wide water-quality adaptability
A multi-system transition-metal composite catalytic formula matches more than ten different water qualities such as printing-dyeing, pharmaceutical, petrochemical, landfill leachate, coking and metallurgy, with stable degradation of phenols, dyes, humus, antibiotics and polycyclic aromatic hydrocarbons; small noble-metal modification can be added on demand, balancing cost and treatment effect.

Ultra-high specific surface area microporous carrier, excellent reaction efficiency
A proprietary high-porosity microporous forming process breaks specific surface area past 250 m2/g, with ample internally connected microporous channels; gas, water and catalyst have full three-phase contact, short hydraulic retention, and for the same treatment scale the reaction tank footprint is smaller and civil investment lower.

Atomic-deposition hydrophilic modification, long-term anti-fouling and anti-clogging
A stable hydrophilic isolation layer is built on the particle surface, so suspended solids, emulsified oil and macromolecular colloids hardly adhere to the pore walls, greatly lowering the probability of media hardening and clogging; for coking and printing-dyeing enterprises the annual shutdown-cleaning frequency drops by 75%, reducing shutdown losses and O&M labor.

High-temperature gradient sintering forming, extremely low mechanical loss
A multi-stage precise temperature-controlled high-temperature sintering process gives the particles a dense, uniform structure that hardly breaks or powders under gas-water backwash and high-velocity hydraulic scour; annual wear rate <= 0.3%; yearly media makeup is minimal and hazardous-waste output greatly reduced.

Acid/alkali and high-salinity tolerant, stable under harsh water
pH tolerance 2-12; strongly acidic, strongly alkaline and conventional high-salinity wastewater can all run continuously long term; active species hardly leach or lose, no heavy-metal secondary water pollution, suiting landfill leachate and chemical acid/alkali intermittent-discharge conditions.

Long life and renewable, high overall project cost performance
Standard industrial service life exceeds 5 years; after activity decline the media can recover over 90% of catalytic performance through simple acid washing, lengthening the overall replacement cycle; versus high-end noble-metal models the purchase cost is lower, giving small and medium wastewater stations and upgrade projects a clear edge in overall O&M cost.

Full-process complete-set compatibility, mature process matching
Perfectly matches SINOKLE'sCDFUcyclonic dissolved-air flotationCDOFand ozone-oxidation complete-set equipment; the front-end physical process removes floating oil and suspended solids to protect catalyst active sites; the whole process needs no heavy dosing of flocculation or decolorization reagents, greatly cutting chemical-sludge output, suiting skid-mounted modular retrofit projects.
