(FR2700323-A1)      Biological treatment of polluted water, sludge and sediments is by using bacteria, fungi or yeasts in growth phase.    Stored microorganisms are mixed with water to produce an initial soln. which is activated by agitation and heating to 10-70 deg.C. After activation, the soln. is distributed into the liq. to be treated via a diffusion tube on the base of the medium. The appts. comprises the means of activation (MA) of the microorganisms, distribution (MD) of microorganisms into the liq. to be treated and a control system (MR). Activation (MA) of the microorganisms in the treatment soln. takes place in a vessel with an agitator, driven by a motor and a gas supply with valve. The vessel is enclosed in a second vessel, with heater, contg. heated water.    USE/ADVANTAGE -   Used to treat domestic, industrial and agricultural pollution. Microorganisms can be selected to suit type of pollution, and a mixt. of microorganisms can be used, aerobic or anaerobic. Max. activity of microorganisms by addn. during growth phase. Appts. is portable.    (EP607096-B1)      Biological treatment of polluted water, sludge and sediments is by using bacteria, fungi or yeasts in growth phase.
