Aerofloat is an integrated wastewater treatment technology, suitable for treating oil-containing wastewater, suspended solids污水, and more. It can be widely applied in various scenarios for wastewater flotation and purification, achieving standard discharge or reuse.

The flotation system is primarily divided into three functional units: the gas-liquid pressurization unit, the microbubble generation unit, and the microbubble flotation separation unit.

Principle:

Common wastewater treatment methods include: physical treatment, chemical treatment, physical-chemical treatment, and biological treatment. Physical treatment methods include: gravity separation, centrifugal separation, air flotation, filtration, and membrane separation, etc.

The concept of treating wastewater using the Microbubble Flotation and Cyclone Flotation Separation Method involves passing gas through a microbubble generator to cut and select fine, uniform, high-density saturated aerated water, which is then introduced into the wastewater to create a three-phase mixture of water-gas-oil droplets or suspended solids. Due to the large number of fine bubbles that separate from the water and adhere to suspended particles and oil droplets, making their density less than that of water, they float to the surface, achieving the purpose of solid-liquid separation. The wastewater treated by this method can remove dispersed oil, emulsified oil, and suspended solids.

Adhesion is the key to the success of the flotation process; only oil droplets and suspended particles attached to bubbles can be separated. The necessary condition for adhesion is to produce suitable fine bubbles. Oil droplets and suspended particles generally have hydrophobic properties and can be attached by bubbles, but not all bubble sizes can hold onto oil droplets and suspended particles. Particularly for particles within the 10-100μm range, if the bubble size is larger than that of the adsorbed oil droplets and suspended particles, it reduces the likelihood of adhesion. Additionally, it may also break up oil-gas aggregates due to inertial forces, causing severe disturbances in the flotation zone. The flotation process plays a bridging role in water treatment technology, especially in reducing the load on subsequent filtration processes and ensuring the final effluent meets standards, playing a crucial role.

Technical Features:

•Utilizing a microbubble generator, the cutting and selection process produces 5-15um microbubble saturated dissolved air water, with uniform and tiny bubble particles, larger specific surface area, and less prone to rupture.

•Easily adheres to oil droplets or suspended particles, with high adhesion efficiency, achieving rapid separation.The separator maintains stability and is resistant to re-mixing; the dissolved air in water with minimal bubbles causes minimal disturbance in the convection field, thereby enhancing separation efficiency.

•Flotation agent usage is reduced.

•Automatic control, easy operation, and stable continuous separation.

•High load handling capacity with minimal land footprint.

•Fluid dynamic collection of suspended particles, no mechanical transmission parts, high reliability, low maintenance costs.

•Separate oil droplets or suspended particles from water by utilizing the hydrocyclone's flotation action.

Efficiency:

•The oil and suspended solids removal rate for high oil content can reach over 95% (90-99%).

•Combining filtration with other processes can enhance efficiency.

Application Fields:

Widely applied in oil fields, refineries, petrochemical and chemical plants, natural gas processing plants, and similar industries for the treatment of industrial wastewater containing oil and suspended solids. Typical applications include:

•Treatment of oil and gas field produced water and suspended solids.

•Wastewater treatment in the paper industry

•Municipal wastewater treatmentDesalination and similar technologies;

•Microbubble aeration flotation is an economical water treatment process technology.

•Primarily used for removing difficult-to-separate solid suspended particles (TSS), oil, fats, and color removal in water purification processes.

Technical Specifications:

•The dissolved air generator, after cutting and brushing, produces fine, uniform, high-surface-area microbubbles and high-concentration saturated microbubble dissolved air water.

•High solubility efficiency; high adhesion efficiency, high separation efficiency, and stability.
