SINOKLE Carbon-Based Ozone Catalyst KHC-F1001: Comprehensive Evaluation and Applications

As a national high-tech and specialized-innovative environmental protection enterprise, SINOKLE leverages years of R&D accumulation in wastewater advanced oxidation technology,and has independently launched the KHC-F1001 carbon-based ozone catalyst. Using high-iodine-value activated carbon as the carrier and paired with a proprietary active-component loading modification process, it overcomes the bottlenecks of traditional ozone catalytic technology and can form a complete refining wastewater treatment combination system with the company's atmospheric and vacuum electric desalting pure physical oil removal process, realizing the whole-process wastewater treatment of 'front-end coalescence flotation oil removal + back-end carbon-based ozone deep oxidation',covering multiple high-difficulty wastewater treatment scenarios across industries, and is currently the mainstream preferred media for ozone catalytic oxidation processes.

Product Fundamentals and Core Performance Evaluation

(1) Catalytic Mechanism

KHC-F1001 selects high-porosity activated carbon with an iodine adsorption value above 1100 mg/g and a specific surface area of 1400 m2/g as the substrate, with active catalytic components loaded through a special loading process. The high-specific-surface-area carrier provides a massive number of active sites, greatly improving the contact efficiency between ozone and organic matter in wastewater; the catalyst accelerates ozone decomposition, quickly generating strongly oxidizing hydroxyl radicals. The oxidation rate is more than 10 times that of ozone oxidation alone, directly mineralizing macromolecular refractory organic matter into carbon dioxide and water, efficiently reducing COD, color and toxic organic pollutants, while improving wastewater biodegradability and reducing the burden on subsequent biochemical and reuse processes.

The catalyst's performance indicators lead similar industry products, with standardized parameters as follows:

(3) Comprehensive Evaluation of Six Core Advantages

Ultra-high catalytic activity, leapfrog improvement in degradation efficiency
Unique active-component loading modification technology, paired with a super-hydrophilic surface process, allows the catalyst to disperse evenly in water with high mass transfer efficiency, greatly accelerating hydroxyl radical generation. At the same ozone dosage, COD and total color removal effects far exceed ordinary carbon-based and silica-alumina-based catalysts, shortening reaction retention time and reducing equipment footprint, suited to skid-mounted integrated equipment, and can be matched with SINOKLECDFUcyclonic dissolved-air flotation,CDOFand ozone oxidation equipment as a complete package.

Super-hydrophilic modification, anti-scaling and anti-fouling
Special hydrophilic surface modification treatment allows water to form a protective water film on the catalyst particle surface, avoiding oil and suspended solids adhering and clogging pores, especially suited to deep treatment of high-oil wastewater such as refining electric-desalting cut water. Long-term operation shows no obvious catalytic activity decay, reducing equipment backwashing frequency and operation and maintenance workload.

Broad-spectrum stable tolerance, suitable for complex water quality conditions
Resistant to acid-base and high temperature, stable operation across a wide pH range of 3-11; excellent impact resistance against high-salinity, oily, high-color and high-COD fluctuating wastewater. Even with large influent quality fluctuations, the oxidation treatment effect remains stable, suited to industrial scenarios with drastic water quality fluctuations such as refining, dyeing and landfill leachate.

High mechanical strength, easy recovery and regeneration, outstanding economy
Particle strength reaches 95%, not easily pulverized or lost under water scouring and air-water backwashing; after deactivation, the media can be restored to catalytic activity through a simple regeneration process, without overall replacement. The 3-5 year ultra-long service life greatly reduces media procurement and hazardous waste disposal costs, significantly lowering the whole life-cycle comprehensive operation and maintenance cost.

Pure carbon-based green material, no secondary pollution
The carrier is high-quality activated carbon, free of heavy metals and toxic harmful components, with no toxic by-products generated during catalytic reaction; different from homogeneous metal-ion catalysts, there is no metal loss causing water secondary pollution, with small hazardous waste generation, meeting green low-carbon environmental governance requirements.

Strong compatibility, can be connected in series with SINOKLE's entire water treatment process
The front end can connect with the company's high-efficiency coalescence oil remover +CDFUcyclonic dissolved-air flotation pure physical oil removal skid equipment, first removing over 90% of floating oil and emulsified oil from electric-desalting cut water, then entering the KHC-F1001 ozone catalytic unit for deep degradation of residual dissolved oil and organic pollutants, forming an integrated refining wastewater solution of 'physical oil removal + advanced oxidation', solving the dual pain points of difficult front-end emulsion removal and back-end COD exceedance in petrochemical sewage.

Multi-industry Implementation Scenarios and Engineering Case Effects

The KHC-F1001 carbon-based ozone catalyst is suited to the ozone catalytic oxidation process, covering eight mainstream fields including petroleum refining, landfill leachate, dyeing, fine chemicals, pharmaceuticals, power, metallurgy and municipal wastewater upgrading, with multiple long-running projects verifying stable and reliable treatment effects.

Project overview: After pretreatment by SINOKLE coalescence +CDFUflotation of a large petrochemical atmospheric and vacuum unit's electric-desalting cut water, the effluent oil drops below 50 mg/L, but residual dissolved oil, gum and refractory organic pollutants in the water cause high back-end biochemical influent COD. KHC-F1001 ozone catalytic oxidation deep treatment is adopted.

Operating parameters:Ozone dosage 100 ppm, catalyst dosage 5 g/L, hydraulic retention 30 min.

Treatment effect:Raw water COD drops from 320 mg/L to 40 mg/L; influent oil 180 mg/L after two-stage process treatment yields effluent oil as low as 0.5 mg/L, with color removal rate above 99%, guaranteeing stable compliant discharge and reclaimed water reuse of refining sewage, while recovering crude oil for economic benefit, achieving the dual benefit of pollution control and efficiency.
