SINOKLE EDUR High-Efficiency Dissolved Gas System: Redefining the Performance of Dissolved Air Flotation for Industrial Wastewater
The SINOKLE EDUR high-efficiency dissolved gas system is equipped with core components of the German-made EDUR multiphase pump and integrates independently developed patented technologies such as swirl centrifugation and ultra-fine bubble generation. It is the core supporting system of the dissolved air flotation process. Compared with traditional dissolved gas systems, it achieves all-round upgrades in dissolved gas efficiency, operational stability, adaptability, and economy, and can be widely adapted to flotation processes for treating landfill leachate, oily refinery wastewater, oilfield wastewater, and many other types of industrial wastewater.
1. Ultra-High-Efficiency Dissolved Gas with Industry-Leading Micro-Bubble Performance
The system relies on the EDUR multiphase pump's special open impeller structure, in which gas and liquid are fully mixed in a highly dispersed manner inside the pump, so that the dissolved gas solubility of the liquid can reach 100% saturation, far higher than traditional dissolved gas systems; it can stably produce ultra-fine bubbles with an average diameter of ≤26μm, with uniform bubble size and a specific surface area increased by 10 times, greatly improving collision and adhesion efficiency with pollutant particles; the capture and removal of fine suspended solids and emulsified oil is significantly better than with traditional processes.
2. A Streamlined and Reliable System with Outstanding Operational Stability
Gas is drawn in directly through the vacuum at the pump inlet, eliminating the need for traditional auxiliary components such as air compressors, pressure vessels, and release devices, greatly simplifying the system structure, reducing moving parts and piping connections, and lowering failure points; it can stably convey liquid with a gas content of up to 30%, maintaining efficient dissolved gas performance even when flow, gas volume, and water quality load fluctuate. It has strong shock resistance and no mechanical power component wear, adapting to the complex conditions of industrial wastewater treatment.
3. Doubled Treatment Efficiency and Greatly Shortened Process Time
Ultra-fine bubbles work in synergy with a swirl centrifugal force field to strengthen the coalescence and separation efficiency of pollutants and bubbles; the hydraulic residence time of the supporting flotation process can be shortened to 1-5 minutes, far lower than the process time of traditional dissolved gas systems; single-stage de-oiling efficiency > 90%, efficiently removing oil droplets of ≥0.3 microns and fine suspended solids, greatly improving the treatment efficiency of the overall wastewater treatment process and enabling rapid compliance treatment of wastewater.
4. Significant Energy Saving with High Industrial Operating Economy
EDUR The open impeller structure of the multiphase pump delivers excellent energy-saving performance; combined with the streamlined design with no auxiliary components and few pipelines, overall system energy consumption is reduced by more than 40% or more. No chemical demulsification or coagulation aids are needed, reducing chemical costs at the source; scum and sludge output is greatly reduced, lowering solid waste disposal costs; and the equipment has no wearing parts and is simple to maintain, further saving labor and O&M expenses.
5. Integrated Design with a Small Footprint and Flexible Deployment
The system uses a compact integrated design requiring no large-scale civil works, with a footprint of only 1/8-1/3 of that of traditional dissolved gas systems, suitable for applications with limited industrial site space; skid-mounted customization is supported, allowing dissolved gas parameters to be adjusted according to project capacity and water quality characteristics, and it interfaces seamlessly with CDFUswirl dissolved air flotation, CDOFand catalytic oxidation processes. Installation and commissioning are convenient, enabling rapid project implementation and a shorter construction cycle.
, 6. Broad Adaptability with Multi-Scenario Application Results Proven in Practice
The system can serve not only as the core dissolved gas supporting unit for landfill leachate pre-treatment, but also perfectly adapts to the treatment of refinery electric desalting wastewater, oilfield fracturing flowback fluid, tank farm black water, food processing oily wastewater, and many other types of difficult industrial wastewater. It has been successfully applied by many benchmark refining enterprises such as Sinopec and PetroChina as well as oilfield projects, with effluent oil content stably controlled at 150mg/L or less, maintaining stable treatment performance under complex water quality conditions such as low temperature, high emulsification, and high salinity; its technological maturity and application reliability are fully supported by practice.
7. Green and Environmentally Friendly with No Secondary Pollution and Safe Operation
The system performs purely physical dissolved gas separation throughout, with no chemical addition, no metal leaching, and no concentrate generation, avoiding secondary pollution at the source; it can operate fully sealed under pressure, with no odor diffusion and no leakage risk, meeting environmental discharge standards and industrial production safety requirements; and the supporting intelligent control system supports remote monitoring and unattended operation, making operation convenient and enabling real-time control of operating status, further improving the environmental friendliness and safety of the process.
8. Corrosion-Resistant and Durable with a Long Service Life and Low Maintenance Cost
The core contact parts of the system are made of special anti-corrosion materials and can withstand corrosive media in industrial wastewater, adapting to ≤50℃, ≤0.1mPa operating conditions, with a long overall equipment service life; the structure is simple with no wearing parts and supports online cleaning and /backwashing, maintaining efficient dissolved gas performance over the long term, with low maintenance frequency and maintenance costs of only 1/3.
Summary: The SINOKLE EDUR high-efficiency dissolved gas system, based on German-made core components and integrating multiple independently developed patented technologies, achieves a comprehensive breakthrough in dissolved gas efficiency, treatment performance, and operating economy.Its ultra-high-efficiency micro-bubble generation capability, streamlined and stable system structure, and significant energy-saving performance greatly improve the treatment efficiency of the dissolved air flotation process, while the integrated design greatly reduces site and deployment costs, and its corrosion resistance and durability further reduce O&M investment.
With broad adaptability, environmental friendliness, and application results fully proven in practice, the system can not only perfectly support landfill leachate treatment processes but also meet the dissolved gas needs of difficult industrial wastewater treatment in many industries, making it a high-quality core supporting choice for upgrading dissolved air flotation processes and providing reliable technical support for efficient industrial wastewater treatment.
