Abstract

Title device, esp. for septic tanks, consists of a cylindrical recipient with a movable, inclined cover with holes acting as a strainer. The device is placed below the pipe which feeds the effluents into the tank; it is fixed to this pipe or to the wall of the tank and dips into the liq. layer. The recipient is fitted with an overflow pipe. The culture medium in the device can be fed with fresh organisms and natural nutritive substances can be added as required; at the same time a certain amt of mixing and agitation is effected in the culture medium itself.
