Abstract
Water purification using biological treatment. According to the process the raw water to be treated without preliminary sedimentation is introduced upwards into a first reactor (1) operating in the absence of oxygen, containing free biomass in the form of a sludge bed of high concentration and fed with a high upward flow rate and the effluent (4) is taken into a second reactor (2) operating in the presence of air, a proportion of the water treated (7), overflowing from this second reactor, being recycled to the base of the first reactor (1). Application to the treatment of water containing ammoniacal nitrogen. <IMAGE>
