RADIOACTIVE EFFLUENTS TREATMENT METHOD Russian patent published in 2007 - IPC G21F9/04 

FIELD: treatment of radioactive effluents and solid-phase saturated waters.

SUBSTANCE: some portion of organic fraction is reduced in first reactor by way of biological aerobic treatment. Filtrate/permeate taken from tangential filtering device is either directly used or supplied to first or next reactor. Solid phase is gravitationally extracted within tank of partial-flow filtering device and compacted in bottom region; concentrated effluents flowing from tangential filtering device are fed in next sedimentation region which is above first sedimentation region or above next one through intake channel; then effluents flowing above or from one side of sedimentation region are discharged through branch channel.

EFFECT: ability of selecting and technically optimizing separate modules.
