摘要

The wave operated upwelling machine for the feed of nutrient rich cold deep water into the upper sea levels in order to mix the deep water with the upper levels consists of a buoy (A), a hose (C) with a mixing module (D), the actual feed hose with a reinforcing cable cordage, a check valve (B), and a downwards hanging counterweight. The check valve is designed as a grid of individual small check valves, or as a valve grid with overlapping flexible membrane valves. The mixing module consists of a number of outlet holes become larger in the upwards direction and which ensure a constant volume outlet per vertical section.
