Microbubble generators are used, for example, in waste water treatment or in industrial processes to introduce gases and for flotation. Unwanted substances such as fine particles, fats and oils can be removed in this way. The MicroGas™ makes this possible with significantly lower space and energy requirements.
In contrast to conventional technologies for generating microbubbles based on the principle of gas dissolution, the innovative MicroGas™ technology is based on the direct induction of microbubbles. The microbubbles generated in this way are only 40 to 60 micrometers in size and have a surface area 600 times larger than that of conventional diffusers. This larger gas-liquid interface enables significantly higher gas transfer efficiencies. It also reduces space and energy requirements.
The MicroGas™ microbubble generator is available for gas transfer and flotation applications and allows the use of a wide variety of gases. It is used in particular as a diffuser for waste water, in oxygen enrichment systems for hydroponic systems and in the food and beverage industry.
Its integration into flotation systems - such as the akvoFloat™ flotation-filtration process - enables the treatment of difficult-to-treat industrial wastewater with high concentrations of oil and suspended solids. The process is mainly used in water-intensive processes in the oil and gas industry, refineries and petrochemicals, as well as in metal processing and steel production.
In the WavE joint project "PAkmem", various solutions for the recycling of industrial wastewater were developed. For use in the oil and gas industry, a detailed safety concept had to be developed for the technologies with regard to explosion protection. A risk assessment and structural development in accordance with the ATEX directives (equipment class 2) were carried out accordingly. Among other things, the device was successfully operated with nitrogen in an oxygen-free environment during the pilot phase.
