This video shows the shutdown process of a MicroGas™ microbubble generator installed in one of our flotation-filtration wastewater treatment plants. The so called "white water" can be clearly observed.
NOTE: the water was not flowing (filtration was deactivated) during the shooting of this video.
The MicroGas™ Microbubble Generator is the most cost-efficient and robust flotation device to maximize the removal of suspended solids and Fat, Oil & Grease (FOG) regardless of pH, temperature or salinity. Originally designed as a minimal-equipment, low-OpEx alternative to DAF, the MicroGas™ Microbubble Generator has many applications including water and wastewater treatment, chemical reactors and aquaculture.
Its novel technology is based on ceramic diffuser discs mounted on a rotating shaft. Compressed air/gas is injected at 1-2 bar into the shaft and permeates through the diffusers into the liquid, where a cloud of microbubbles between 50 - 70 micron is generated (white water) with an extremely low energy consumption. Unlike in DAF systems, no pressure is required to dissolve the gas into the liquid, and hence energy consumption is not reliant on salinity and temperature of the water. Furthermore, flotation systems based on MicroGas™ do not require saturation vessel, recycle pumps or nozzles, making them more reliable and cost-effective.
