Preparation based on specially selected and freeze-dried non-pathogenic bacteria.

Bacteria can be useful for the reduction of C.O.D., for the reduction of nitrogen (denitrifying bacteria), for the reduction of surfactants, for the reduction of oils and fats, for the transformation of organic nitrogen into nitrites and nitrates (nitrifying bacteria).

Food, chemical, pharmaceutical, dyeing, printing industries.

Improvement of the bacterial flora and of the flake, very rapid ignition of the plant, acceleration of the attack phases of the pollutant load, reduction of the pollutant load at the outlet, abatement of BOD and COD, reduction of floating sludge due to filamentous microorganisms, reduction of oxygen consumption, abatement of residual color.
