PURIFICATION METHOD BY MIXING/DIFFUSION OF CLOSED WATER ZONE AND MIXING/DIFFUSION APPARATUS

Title:

PURIFICATION METHOD BY MIXING/DIFFUSION OF CLOSED WATER ZONE AND MIXING/DIFFUSION APPARATUS

Document Type and Number:

WIPO Patent Application WO/1998/002385

Kind Code:

A1

Abstract:

A purification method by mixing and diffusion of a closed water zone involves the steps of sucking bottom layer water and surface layer water, preparing mixed water by mixing them before discharging, and discharging mixed water into a water layer having substantially the same temperature as that of mixed water to form and diffuse a density current of mixed water. Therefore, convection in a vertical direction can be prevented, and mixed water can be quickly diffused across a broad range of a closed water zone.
