ZJC-NM Micro Nanometer Air Floatation Machine
Micro-nano bubbles are small bubbles with diameters of micrometers and nanometers. They have slow rising speed, long residence time, high dissolution efficiency in water, and possess characteristics such as self oxygenation, negative charge, and rich in strong oxidizing free radicals. Micro/nano bubbles not only have a high potential generated by surface charges, but also have a large specific surface area. Therefore, the combination of micro/nano technology and coagulation technology in wastewater pretreatment has shown good adsorption effects and efficient removal rates for suspended solids and oils.
ZJC-NM type micro/nano air floatation machine, based on the characteristics of micro/nano bubbles, uses a specific physical structure to efficiently mix and dissolve gas and liquid to produce a large number of micro/nano bubbles, which fully contact with suspended solids in water. Due to the large surface area of micro/nano bubbles, they can adhere to a large number of suspended flocs in water and float away from the water surface with the micro bubbles, forming scum and then scraping off the scum, Thereby purifying the suspended impurities and fine oil in the water. When micro and nano bubbles burst, they generate free radicals, break the complex and bond, and improve the biochemical performance of wastewater to quickly and efficiently remove odors from wastewater. The micro/nano air floatation machine mainly plays a role in solid-liquid separation and oil removal (which can simultaneously reduce COD, BOD, chromaticity, and odor in water). The micro/nano bubbles produced by the micro/nano air flotation machine are emulsified, with high density, uniform distribution, and long stable residence time, forming a large specific surface area contact between the gas and liquid phases, thereby achieving efficient two-phase mixing. Outstanding separation effect for suspended solids and oils.
Micro/nano air flotation and flocculation equipment are seamlessly combined, with small particle size of micro/nano bubbles, large specific surface area, and high separation efficiency of suspended solids, which can reduce the use of reagents and facilitate installation with existing equipment.
It is applied to the sewage treatment of offshore and onshore oil and gas fields of CNOOC, PetroChina, and Sinopec, and is the preferred technology for upgrading the old gas floatation technology to save energy and reduce consumption. Provide high-quality micro bubble dissolved water for air flotation facilities in oil and gas fields, refining, coal chemical, steel, printing and dyeing, paper making, municipal and other industries, and improve the efficiency of decontamination. Provide micro bubble dissolved water for oil and gas field settling tanks, inclined plate oil removers, etc., to improve oil removal efficiency.
