EDUR High-Efficiency Dissolved Gas System: Revolutionizing Water Treatment with Advanced Micro-Bubble Technology

In oil-containing wastewater treatment, sludge flotation, and catalytic oxidation of difficult-to-degrade organic compounds, the performance of the dissolved gas system directly determines the subsequent separation and reaction efficiency. Traditional dissolved gas systems face multiple pain points: First, the bubble size is large (usually > 50 μm) and unevenly distributed, leading to insufficient gas-liquid contact and low treatment efficiency; second, a large amount of gas is required (usually > 5%), which necessitates a large nitrogen production or aeration auxiliary system, resulting in high infrastructure and operating costs; third, the release devices are prone to scaling and clogging, requiring frequent and difficult maintenance, with significant downtime losses; fourth, energy consumption remains high, which contradicts the current industry trend of environmental protection and energy saving.

The Shenzhen Clear Science & Technology Co., Ltd (SINOKLE) introduced Germany's EDUR core technology to create an efficient dissolved gas system. Through technological optimization and localization adaptation, this system thoroughly solves the challenges faced by traditional systems and has become a core supporting device for efficient, stable, and economical water treatment.

The EDUR high-efficiency dissolved gas system from the SINOKLE uses the German-made EDUR multiphase flow pump as its core and integrates proprietary micro-bubble release technology. With more than 30 years of technological iteration, it has established an industry barrier in terms of stability and efficiency. Its core technological advantage lies in precise control over the principles of dissolved gas and structural innovation. As the "power heart" of the system, the EDUR multiphase flow pump inherits German precision manufacturing technology and offers strong reliability and adaptability. Unlike traditional centrifugal pumps that only transport a single fluid, this pump can directly mix gas and liquid and pressurize dissolved gas without the need for additional gas-liquid mixing tanks, simplifying the system structure. Its unique impeller design has strong anti-cavitation ability and can operate stably at gas injection rates of 2-3% (volume ratio, standard state gas), avoiding efficiency degradation caused by gas accumulation in traditional pumps, providing continuous power for stable micro-bubble generation.

The system's core breakthrough lies in the proprietary micro-bubble release technology, which achieves three key optimizations through special structural design:

1. Precise and controllable particle size: The micro-bubble particle size is stabilized at 5-30 microns, with a uniform distribution. Compared to traditional dissolved gas systems (50-100 microns), the bubble-specific surface area is increased by more than 10 times, greatly increasing the gas-liquid contact area and enhancing mass transfer efficiency by 3-5 times.

2. Anti-clogging and easy maintenance: A large-diameter pipeline release structure is used, which can be flexibly adjusted according to the water quality scenario, reducing the risk of scaling and clogging at the source. The release device adopts a flange installation design, making it easy to disassemble, replace, and clean, with a maintenance cycle 60% longer than traditional equipment.

3. Low energy consumption and high efficiency: The gas injection amount only needs to be 2-3% of the treated water volume, far lower than the 5-8% gas injection requirement of traditional systems. It does not require large auxiliary nitrogen or aeration systems, significantly reducing infrastructure investment and operating energy consumption.

Based on the EDUR core technology, the SINOKLE has localized the system to adapt to complex water quality scenarios in various regions. Material adaptation: The release devices and contact components can be optionally made of stainless steel or anti-corrosion coatings to suit high-salinity, highly corrosive wastewater scenarios, extending the equipment's service life. It supports seamless integration with the SINOKLE's CDFU flotation equipment and heterogeneous ozone catalytic system, enabling precise matching of dissolved gas volume, bubble size, and subsequent processes, improving overall treatment efficiency by more than 20%. Fluid dynamics simulation optimizes the flow path design, and the EDUR multiphase flow pump's motor efficiency reaches IE3 or higher, reducing energy consumption per ton of water by 40%-50% compared to traditional dissolved gas systems.

The core performance differences between the SINOKLE's EDUR high-efficiency dissolved gas system and traditional systems are clearly illustrated in the following parameters, showing its advantages in terms of efficiency, cost, and maintenance:
