AI Technical Summary

Technical Problem

Existing water circulation and aeration systems are inefficient, require high energy input, and can harm aquatic life, with limited operation in calm weather conditions and inadequate oxygen enrichment, especially in turbid waters.

Method used

A passive forced-action mixer with a built-in guide device creates intersecting flows by moving through the water, mixing upper and lower layers without dedicated flow generation, using minimal energy and gentle on aquatic life, enhancing oxygen diffusion and productivity.

Benefits of technology

The mixer efficiently circulates and aerates water with minimal energy loss, maintaining optimal oxygen levels and promoting algae activity, while being gentle on aquatic organisms and operating in various weather conditions.

Abstract

Device and method for circulating and aerating a body of water, comprising a circulation arrangement (1). According to the invention, the circulation arrangement (1) is designed as a forced mixer (1) that operates passively and, by means of a built-in guide device (24), generates at least two separately guided, intersecting flows (16) inside a housing (2) of the forced mixer (1) between an inlet opening (12) and an outlet opening (14), wherein a lower water layer (8) is conveyed upwards and an upper water layer (10) is conveyed downwards simultaneously, wherein the forced mixer (1) extends to the lower region of the lower water layer (8) that is to be exchanged with the upper water layer (10). Use of a device for circulating and aerating a body of water.
