摘要 |
<p>The method, in which the water to be treated is partly oxygenated by a specific aeration carried out before percolation through a biofilter having a bacteria-supporting bed of filtering material, has a measurement stage of at least one parameter constituted by the oxidation-reduction potential of the aerated water before passage into the biofilter, a transmission stage of measurement signals to a computer and comparison of the signal representative of the value of the measured parameter with at least one lower limit set in function of the measurement carried out in a second stage for measuring a parameter representative of the pH and a stage for correcting the air flow by a signal determined by the computer in function of the two preceding stages.</p> |
