Micro Nano Bubble Generator Mixing Pump/DAF pump/for Dissolved Air Floatation 80EDQS185S

Product Description


The micro nano bubble generator is using a simple method to generate micro bubbles in a liquid. This bubble generator uses the properties of the vortex pump turbine and effectively absorbs gas with a liquid or two liquids, and adding it under pressure into a process. A device that can be useful for efficient mixing and dissolving of the gaseous products in fluids. It is for this purpose equipped with a special impeller and can be used for continuous operation.



As a thesis published by Futyu Laboratory shows that the application of micro bubbles can greatly improve the growth of aquacultures like oysters, scallops and other marine products, we suggest all the customers in the aquaculture cultivation industrial should try this method to improve the efficiency of cultivation.

Dissolved Air Flotation

Dissolved air flotation (DAF), which is mainly used in wastewater treatment system, is a reliable and proven process for purification. DAF is used for the easy separation of suspended matters in liquids. The DAF system works by saturating the process water with air under high pressure which is then released to normal pressure and piped into the wastewater tank. The micro bubbles generated during pressure release work to attract suspended particles in the liquid and float them to the surface where they are then skimmed away.


The micro bubble generator’s ideal fields of application includes the treatment of oil-water emulsions, fat separations, phosphate precipitations and heavy metal precipitations as well as final sedimentation at bio-treatment plants. Multistage flotation plants are a solution to the treatment of special waste.


When using the Micro Bubble Generator, the gas is fed directly into the inflow pipe. This way can considerably reduce the components compared to the traditional DAF system. The compressor, pressure tank, pumps, control, and numerous valves can be removed.


During pressure generated in the DAF system, Micro Bubble Generator achieve a thorough homogeneous mixing of liquid and gas. The gas saturation can be further increased by adding additional downstream solution lines.


The Micro Bubble Generator can produce bubbles whose diameter is between 30-50 microns depending on the waste water and the saturation pressure dispersions.





According to the customers report, considerable energy has been saved after using Micro Bubble Generator besides improved effluent values and a reduced input of chemicals. Micro Bubble Generators do convince stable conveying features and low wear operation compared to side channel pumps.

Micro Bubble Generator are operated with clean liquid. Pre-cleaned water in the recycle –flow process. Also during starting phase attention must be paid to the water cleanness.

Realize inflow conditions at pump inlet side. Make sure liquid is filled with pump body.

Select throttle valve and pressure release valve with good dosing features

Install gas supply line above highest liquid level to keep liquid away from entering the air flow measuring device.

Select air flow measuring device with suitable metering range and with needle valve for optimal adjustment of the air flow.

Design inflow-pipe from air inlet to pump inlet flange in a short and horizontal way in order to ensure that always a constant water-air proportion arrives at the pump.

As solution line for dissolved air flotation a pipe line with larger nominal width will be suitable in order to achieve a retention period of approx. 1 minutes until pressure release.

If required, surplus air can be led away by means of a bubble separation at highest position before pressure release (pipe line with very small nominal width).

Initial Starting

Initially pump is started according to the known operating instruction for pure water supply. Check the maximum pump pressure as per characteristic curve point by short-time closing of the pressure release valve while the bubble separation pipe is closed.

Open the pressure release valve until the required operation pressure for pure water supply has been reached. At the same time, it has to be considered that the flow rate for pure water supply has to be approx. 10 to 20% higher than for the supply of water-gas mixtures.

Reduce the rate of flow slightly at the inlet side by means of the throttle valve till a pressure (vacuum) between -0.2 and -0.3 bar is achieved at the suction side manometer. Open the air supply at the throttle valve and adjust the required air flow gradually at the needle valve. The operating pressure at the pressure side manometer decreases slightly. If necessary, re-adjust the vacuum at the pump inlet side in case that the required air flow will not be sucked in from the atmospheric air. In case of delivery stops the air flow has to be reduced accordingly.

In order to avoid large bubbles the gas contents must not exceed the physically possible solubility.

Other gases also can be charged considering the solubility. Differing methods also will be possible after consulting.
