SINOKLE KLEX-013 Fine-Chemical High-Concentration Dedicated Ozone Catalyst: Comprehensive Evaluation and Engineering Applications

As a specialized, innovation-driven high-tech environmental enterprise, Shenzhen SINOKLE Technology has long focused on industrial advanced-oxidation wastewater treatment, addressing the pain points of the fine-chemical industry — high COD, highly toxic heterocyclic organics, high salinity, and large water-quality fluctuations.It independently developed the KLEX-013 high-concentration-wastewater dedicated heterogeneous ozone catalyst. The product integrates four proprietary core technologies — a multi-transition-metal + precious-metal composite catalytic formula, high-porosity microporous monolithic shaping, atomic-deposition super-hydrophilic modification, and staged precise high-temperature sintering.Its chemical stability and high-load catalytic performance lead the industry; it can be paired with the company'sCDFUswirl dissolved-air flotation (CDFU),CDOFand integrated ozone-oxidation equipment for complete use, building a full process chain of 'front-end pre-treatment impurity removal + KLEX-013 ozone catalytic deep degradation,' specifically suited to fine-chemical intermediates, synthetic raw materials, pesticides, and fragrances with high-concentration refractory wastewater. It is the preferred catalytic medium for high-load ozone catalysis.

Product catalytic mechanism and core performance indicators

(I) Catalytic mechanism

KLEX-013 uses a highly active porous inorganic substrate, shaped by staged temperature-controlled monolithic sintering, with a multi-level connected micropore structure inside (specific surface area >250 m²/g) and abundant composite-acidic active sites on the surface. It simultaneously loads manganese, iron, and cobalt multi-component transition metals and dopes a trace of precious metal; the precious metal and metal oxides form an electron-synergistic catalytic system that greatly lowers ozone-decomposition activation energy, rapidly catalyzing ozone cleavage to generate abundant hydroxyl radicals (·OH); oxidation efficiency is 2–5× that of conventional ordinary catalysts.

For the stable macromolecular structures of benzene rings, heterocycles, halohydrocarbons, phenols, and pesticide intermediates in fine-chemical wastewater, ·OH non-selectively cleaves organic bonds, directly mineralizing high-concentration refractory pollutants into CO₂ and water, rapidly cutting raw-water high COD, eliminating water biological toxicity, and significantly raising wastewater B/C biodegradability while greatly lowering downstream biochemical and membrane-system load. The carrier-surface atomic-deposition hydrophilic modified layer blocks chemical-wastewater colloids, resins, and emulsified impurities from attaching, ensuring no long-term pore clogging; active components are high-temperature anchored with no loss, eliminating heavy-metal secondary pollution.

(II) Key technical indicators

KLEX-013 eight core product advantages

High-load precious-metal synergistic catalysis, suited to fine-chemical high-concentration wastewater
A multi-metal + precious-metal composite active system optimized for thousands-of-mg/L high-COD chemical wastewater; ozone decomposition utilization stays above 98%. At equal COD-removal standards, ozone dosing drops 40%, reducing ozone-unit capacity and long-term electricity cost; it has extremely strong degradation of benzenes, heterocyclic intermediates, and halogenated organics, with stable decolorization and detoxification at high load.

Ultra-wide water-quality tolerance: salt-, acid/alkali-, and poisoning-resistant
Carrier and active components are tightly bound by high-temperature sintering, with zero active-component precipitation or loss; it tolerates high-salinity wastewater above TDS 60,000 mg/L and stable operation across pH 2–12 swings, showing no rapid deactivation facing organic toxins from fine-chemical pesticides and dye intermediates — solving the ordinary catalyst's pain of easy poisoning and short-term activity collapse.

High mechanical strength, ultra-low wear loss
Particles are monolithically high-temperature sintered, single-granule compressive strength ≥100 N; under gas-water backwash and high-flow high-velocity scouring they resist pulverization; annual wear is kept within 0.3%, greatly reducing regular catalyst replenishment/replacement workload and medium O&M procurement cost.

Super-hydrophilic anti-clog micropore structure, suited to continuous chemical production
A unique atomic-deposition surface hydrophilic-modification process keeps carrier micropores from being clogged by resins, colloids, suspended organics, and emulsified oil in chemical wastewater; no frequent shutdown to dismantle and clean the catalytic tower — fully matching fine-chemical enterprises' year-round 24-hour uninterrupted continuous-production water-treatment mode.

Long service life, easy regeneration, greatly reduced hazardous waste
Standard industrial service life exceeds 5 years, far above ordinary commercial catalytic media. After organic adsorption saturation on the surface, simple water rinse + low-temperature calcination restores original catalytic activity, greatly extending the overall replacement cycle and reducing spent-catalyst hazardous-waste volume and disposal cost — outstanding full-life-cycle economy.

Broad-spectrum degradation of highly toxic organics, dual role of pre-treatment + deep upgrading
Dense multi-level pores plus precious-metal composite active sites work synergistically to simultaneously degrade fine-chemical characteristic pollutants — phenols, benzene/heterocycle, halohydrocarbons, pesticides, fragrance intermediates, and high-color dyes. It serves both as high-concentration raw-liquid pre-treatment, rapidly lowering toxicity and raising biodegradability, and as biochemical tail-water deep treatment for stable compliant reuse.

Package-compatible with SINOKLE pre-treatment equipment, one-stop solution for impurity-laden chemical wastewater
It can be paired with the company's high-efficiency coalescing oil separator,CDFUand swirl dissolved-air flotation (CDFU) equipment for joint use; the front-end purely physical process removes floating oil, suspended solids, and resin impurities, preventing impurities from covering catalyst active sites; the rear KLEX-013 deeply degrades dissolved high-concentration organics, simultaneously solving the dual exceedance of oil and COD in fine-chemical wastewater.

Green low-carbon operation, reduced chemical dosing and secondary pollution
The whole catalytic-oxidation flow needs no large dosing of flocculation, decolorization, or oxidation agents; chemical-sludge output drops over 70%; the carrier leaches no soluble heavy metals, and ozone tail gas can be recovered and recycled, with no exhaust odor emission — fitting fine-chemical parks' clean-production and green low-carbon environmental-control requirements.

The whole system carries online COD, pH, ozone concentration, flow, and pressure real-time instruments; feed distribution, catalytic reaction, gas-water backwash, and tail-gas ozone recovery are fully auto-adjusted, supporting remote cloud monitoring with no dedicated 24-hour on-site attendant, significantly lowering labor O&M cost.Fully enclosed pressurized safe operation:

Wastewater, ozone, and volatile chemical exhaust flow entirely within enclosed chambers and pipelines; odor and toxic exhaust are collected and decomposed centrally, with no uncontrolled leakage — fully meeting fine-chemical-park safety-production and exhaust-control standards.Summary of comprehensive economic and environmental value
