The common aim of the three systems is as follows:
· to absolutely avoid oxygen dispersion by means of suitable recovery and recycling systems for possible undissolved oxygen
· to obtain very high values of aeration efficiency by operating at high pressures, that is in the depth of natural and artificial basins
· avoid surrounding atmospheric pollution
The first of the three systems (STELOX®) has been succesfully installed at the beginning of the Seventies for the regeneration of a natural basin (lake Ghirla - Valganna - ITALY).
The lake regeneration by means of our system has been carried-out in about 40 days of operation through the blowing in the lake of about 7000 Nm3 of oxygen, which has restored the oxygenation conditions necessary to allow the life of the acquatic fauna and flora.
