DEVICE FOR WATER PURIFICATION AND CLARIFICATION Russian patent published in 1999 - IPC

FIELD: reagent purification of sewage and natural water. SUBSTANCE: the device has a casing made in the form of a hollow cylinder, whose lower end is connected to a tapered slime comparator, clarification chamber concentrically positioned in the casing in the form of a truncated cone expanding upwards, and a flocculation chamber placed in it in the form of a cylinder with a conical funnel in the lower part, and partitions some of which are installed tangentionally at the outlet from the funnel, and the others are uniformly arranged inside the chamber across the flow. A cylindrical reaction chamber is installed inside the flocculation chamber. The clarification chamber and the slime comparator are furnished with pipe-lines for discharge of clarified water. EFFECT: enhanced uniformity and stability of the suspended sediment layer maintained due to pressure differential in the clarification chamber and slime comparator produced by separating pipe-lines for discharge of clarified water. 1 dwg
