About This Product

■Upwelling circulation device (cultifan) regenerates closed water area

The upwelling circulation flow generator creates a vertical circulation flow by slowly rotating blades on the water surface. Through this circulating flow, oxygen is absorbed into the bottom water, making it more uniform throughout the pond and purifying the water quality.

■Works and effects

When the blades are rotated to scrape out water from the water surface, the low water rises by the amount scraped out. At the bottom of the water, a laminar flow is created that flows along the bottom and converges at the starting point of the upward flow. Due to this flow, the water temperature throughout the pond becomes uniform, and the surface water with high dissolved oxygen gradually eliminates the lack of oxygen in the lower layers. The low water that rises and is scooped out by the blades flows on the water surface, absorbs oxygen, and releases odor as it settles and returns to its starting point as a laminar flow that contacts the bottom surface. When the ratio of laminar flow that absorbs oxygen increases and oxygen is supplied to the sludge, the sludge decreases, producing ammonia and hydrogen sulfide, and the odor disappears, smoothing the food chain and reducing BOD. , COD, and blue-green algae phenomena will gradually disappear.

■Features and effects

・Collects a large amount of water from a wide area and circulates it vertically with a small amount of energy. ・This is not a device that pumps or sucks up water; it is a device that induces the flow that nature creates. ・The flow created by the device is a vertical flow and a large amount of moving water, which helps to equalize the water temperature throughout the lake. In lakes and marshes where the water temperature is uniform, the rising low water is spread over a wide area by the energy of the blades, and the upper layer water with high dissolved oxygen can be guided to the lower layer. ・In ponds that are not uniform, the rising low water has a lower water temperature than the upper layer water, so it does not spread in the upper layer and simply settles to the same water temperature, making it impossible to lead the upper layer water to a wide range of lower layers. you can't. -The flow created by the device absorbs oxygen and releases decomposed gases and odors. ・The flow in the low layer created by the device prevents oxygen depletion in the low layer and suppresses the elution of nutrients and the generation of hydrogen sulfide. ・The flow created by the device in the lower layer prevents oxygen depletion in the lower layer and suppresses the elution of nutrients and the generation of hydrogen sulfide. ・Due to the low-level flow created by the device, the sludge becomes food for organisms and decreases, and when plankton production cannot keep up, transparency will gradually be restored. ・The vertical flow created by the device worsens the living environment of phytoplankton and suppresses their growth. ・The flow created by the device creates a water area where a smooth food chain is established and an ecosystem with diverse organisms is established.
