ABSTRACT:
The efficiency of clarifiers is improved by providing a contraction adjacent the outlet which accelerates the liquid to a densimetric Froude number at the contraction of at least 0.1/.pi.. The contraction dampens internal waves in the fluid and improves the uniformity of flow of fluid through the tank.
