Total water circulation system for shallow water areas

Abstract

A method and an apparatus are used in shallow water areas having a depth of about two meters or less for producing a total water circulating flow from the bottom toward the top and then from the top toward the bottom, to thereby improve the quality of the total water. The method consists essentially of providing an upward jet of fluid under pressure acting upon a water flow rising from the bottom toward the top through a tubular passage of vertically disposed tubular construction so that the water flow can rise with an increased speed. At the top end of the tubular passage, the water flow is jetted out, forcing a circulating flow with circular motions. The apparatus comprises a vertically disposed tubular construction having a tubular passage through which the water flows and rises, including a member for producing an upward jet of fluid under pressure disposed inside the tubular passage and exposed to the water in the tubular passage.
