  Pure Oxygen Systems

SESPI STELOX®, RISTELOX® and STERILOX® systems are mainly applicable to the polluted water of civil and industrial waste water biological oxidation processes.

  Traditional aeration systems and processes

In the biological depuration technique an attempt has been made to simulate or, better, to intensify the oxygen diffusion natural phenomena from air to water, either by increasing the contact surface, or by keeping the gas-liquid blend in strong agitation, in a turbulent state. 
The turbulent state is increased by the velocity, or kinetics, of the gas in contact with the liquid.
