ABSTRACT:
An apparatus and method for improving the settling out of suspended solids in a liquor are described. A diffuser of a particular type is used to introduce a liquor containing a flocculant suspension into a sedimentation tank with low turbulence. The diffuser is so shaped that the liquor velocity can be reduced in a controlled manner. Liquid shear conditions are made so low inside the diffuser that excessive break-up of flocs does not occur. The diffuser has a flare angle and a discharge opening to throat dimensional ratio whereby these conditions of low turbulence and formation can be established. Several embodiments of sedimentation apparatus employing such diffuser are described.
