From "Membrane" to "Oxidation": SINOKLE Brings Disruptive Change to Landfill Leachate Treatment
To address the pain points of landfill leachate — high salinity, high COD, complex composition and poor degradability — SINOKLE Technology has innovatively launched an integrated treatment system centred on homogeneous and heterogeneous multi-catalytic oxidation technology as its core.
The system deeply integrates CDFUcyclonic dissolved-air flotation, CDOFozone advanced oxidation flotation and ozone micro-nano bubble generation and other cutting-edge processes, aiming to break the technical barriers of conventional membrane treatment and provide customers with dedicated integrated solutions that combine high efficiency with low operating cost.
1. Dual-Mode Catalytic Synergy for Industry-Leading Oxidation Performance
The system is built around homogeneous and heterogeneous multi-catalytic oxidation technology. The homogeneous catalyst enables rapid and efficient generation of hydroxyl radicals (-OH), while the heterogeneous catalyst integrates a range of active metal oxides and high-porosity micro-pore forming technology. Acting together, they rapidly generate hydroxyl radicals, superoxide radicals and other highly active species. Combined with ozone micro-nano bubble generation technology, gas-liquid mass transfer efficiency and ozone utilisation are greatly improved, making ozone oxidation performance more than 4 times better than conventional methods, fundamentally resolving the industry bottleneck of refractory macromolecular organics in landfill leachate.
2. Deep Purification: Efficient and Thorough, Meeting Complex Water Quality Challenges Head-On
Given the complex composition of leachate, the system establishes a tiered purification pathway of “rapid chain scission—strong adsorption—deep mineralisation”.Homogeneous catalysis rapidly attacks the chemical bonds of macromolecular organics and breaks them into readily degradable small molecules; heterogeneous catalysis then deeply oxidises the small-molecule intermediates through its high-porosity structure, ultimately converting them into harmless substances and preventing toxic accumulation.
At the same time, it shows extremely strong removal capability for difficult pollutants such as dissolved oil, phenols and sulphides, with removal rates for colour and odour consistently above 90%. The catalyst is hydrophilically modified for strong anti-fouling performance and pHa wide range of applicability; it maintains stable catalytic activity even in high-salinity environments and offers outstanding resistance to water quality shocks.
3. Efficiency Innovation: Rapid Response and a Significantly Reduced Footprint
Based on the CDOFpatented process design, the system provides ample reaction interface for catalytic reactions, extending contact time between pollutants and active species and greatly improving mass transfer efficiency; the effective reaction time of the core oxidation unit is only 15 minutes, which isof conventional processes. It enables rapid on-site compliant disposal of landfill leachate, solving the problems of low treatment efficiency and long reaction cycles of conventional equipment; treatment capacity reaches up to 200m³/h, adapting to leachate treatment needs of different scales.
4. Cost Reduction and Efficiency Gains: Optimised Economics with Highly Competitive Operating Costs
The synergy of multiple catalytic technologies significantly reduces overall oxidant dosing. Ozone utilisation reaches as high as 99.98% or more, and the ratio of ozone dosage to COD removal (the dosing ratio) drops to 0.5~1.2, far below the conventional 2~4. In addition, the specially modified heterogeneous catalyst has high strength and a long service life (> 5 years), avoiding frequent replacement.Combined with a fully automated operating design, it greatly reduces labour and energy consumption, giving it an overwhelming economic advantage over conventional membrane processes.
5. Skid-Mounted Integration: Flexible Deployment and Fast, Hassle-Free Implementation
The system uses a highly integrated, skid-mounted design with a greatly simplified process flow, occupying only 1/5 of the footprint of conventional leachate treatment equipment, with no need for large-scale civil works. It supports custom fabrication and can be tailored to actual project requirements, perfectly matching the on-site treatment needs of transfer stations, landfills, incineration plants and other scenarios.
6. Stable Operation: Intelligent Control, Simple Maintenance and Long-Term Reliability
The heterogeneous catalyst uses hydrophilic modification anti-fouling and anti-blocking technology. The system operates fully sealed under pressure, fundamentally eliminating ozone leakage for safety and environmental protection. The catalyst's unique backwash, activation and regeneration process maintains stable catalytic performance over the long term.It is also equipped with a fully automatic control system for pressurised, fully enclosed automatic operation, supporting remote monitoring and unattended running and greatly reducing manual operation and equipment maintenance frequency.
7. Green Process: Clean Discharge and No Secondary Pollution
The system uses a full-quantity treatment process that does not rely on reverse osmosis membranes and produces no difficult-to-treat concentrate. Sludge production during treatment is minimal and can be reduced by more than 90%. The entire system runs sealed, with no odour dispersion on site and clear effluent; it avoids the secondary pollution problems of concentrate and waste residue caused by conventional processes at source, matching the ecological and environmental protection requirements of waste treatment facilities.
8. Mature Technology, Wide Application and Proven Results
The system incorporates multiple patented technologies, with core processes that are internationally leading and uniquely developed in China. It offers dedicated solutions for landfill leachate and press liquor, and can also be applied to the pre-treatment of high-difficulty wastewater in pharmaceuticals, metallurgy, oilfields and other industries /and to advanced treatment, as well as to the upgrading and retrofitting of wastewater treatment plants. At home and abroad, there are many successfully operating cases with stable, compliant treatment results, earning wide industry recognition.
Summary
SINOKLE's landfill leachate treatment system, centred on disruptive multi-catalytic oxidation technology, systematically integrates patented processes such as CDOFto provide a highly efficient, economical, stable and green solution to this industry-wide problem of landfill leachate. It sets a new benchmark in oxidation capability and treatment efficiency, and with its significant operating cost advantage and flexible deployment it brings customers genuine added value — a trusted, high-quality choice.
