The innovative "Air inside" process, covered by international patents, combines tubular membranes with an aeration system by means of ejectors, allowing maximum purification efficiency on high-load wastewater with reduced energy consumption.
The mechanical characteristics and the thickness of the tubular membranes confer particular strength to the membrane and allow processing with the air/mud mixture pushed directly inside the fibers. This ensures sufficient turbulence even at low circulation speed, substantially reducing the risk of membrane fouling.
The figure shows the simplified hydraulic diagram of a tubular membrane bioreactor complete with the ejector and nozzle aeration system.
It should be noted that in the system configuration presented above, the only energy required is that to supply the pump, which at the same time guarantees sufficient fluid velocity in the membrane channels and the aspiration and diffusion of the air in the biomass through the ejectors. The installation of blowers or compressors is therefore not required.
The excess sludge can be purged directly from the biological tank.
