<p>1. Process for the biological anaerobic treatment of liquid effluents containing concentrated organic pollutants, in which fermentation is carried out through an immersed bed with a low density lining, free or floating, characterized in that the elements of the lining have a proper density higher than that of the liquid, although at the most equal to 1.5, but a vacuum percentage of free passage rate higher than 90% and a specific useful surface greater than 100 m**2 /m**3 , so that they are caused to float by the fermentation sludges.</p> |
