Abstract:
1. Liquid clarifier for treating a liquid, comprising a liquid reactor which comprises an essentially cylindrical vertical tank having an upper section with substantially vertical walls and a lower tapered section having an outlet for discharging waste, an inner cylinder having a lower region and an upper region that is positioned higher than the lower region, where the inner cylinder extends along at least part of the upper section of the tank and an outlet for clarified liquid at the top of the tank, where the liquid clarifier further comprises a gas source adapted to inject compressed gas into the lower region of the inner cylinder and an inlet for an unclear liquid at the upper region of the inner cylinder, characterized in that the liquid reactor further comprises at least two partition walls inside the lower region of the inner cylinder, where the at least two partition walls create flow channels in the lower region of the inner cylinder, where the compressed gas is adapted to be injected through gas inlets in flow channel/s in order to create an upward liquid flow in the flow channel/s having gas inlets, which will create a downward liquid flow in the flow channel/s without gas inlets so that one downward flow channel is adjacent two upward flow channels via the partition walls, where the at least two partition walls extend out of the lower region of the inner cylinder, and the inner cylinder ends before a bottom of the cylindrical vertical tank.
