The MicroGas™ Bubble 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™ Bubble 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 fine bubbles 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.
Minimal Operating Costs
MicroGas™ only requires compressed air/gas at low pressures (1-2 bar) and a low voltage DC motor.
Unlike in DAF systems, no saturation vessel, recycle pumps or nozzles are required.
The shear forces generated at the surface of the diffusors by the outgoing gas and the rotating shaft prevent them from clogging, having an automatic self-cleaning effect.
