METHOD FOR PURIFYING SEAWATER AND UPWELLING FLOW APPARATUS ALSO SERVED AS MARINE RANCH

摘要

PURPOSE:To easily purify and clear the bottom of the sea by standing in the sea many cylindrical upwelling flow devices each with both ends open. CONSTITUTION:Many cylindrical upwelling flow devices 1 each with both ends open are stood in the sea so as to provide a space between the respective lower ends of the upwelling devices and the bottom 5 of the sea. The upwelling devices are equipped, if needed, with suction pumps, respectively. Nutrient-rich matter suspended close to or sedimented on the bottom of the sea (e.g. plankton) is sucked into the upwelling devices owing to the suction pumps and/or current and discharged through the upper openings of the devices in the form of upwelling flow, thus resulting in consumption of such nutrient-rich matter on the bottom of the sea.
