<p>PURPOSE:To enhance a water purifying effect by sufficiently circulating pond water by ascending water flow and increasing the flow rate without hindering the spread of the jets ejected from he water lifting cylinders. CONSTITUTION:This pneumatic water lifting cylinder A is constituted to generate the ascending water flow and to cause the circulative flow of the nearby water by installing plural pieces of water lifting cylindrical bodies 1 upright at proper points in the water of lakes, swamps, ponds, rivers, etc. The distances between the centers of the respective water lifting cylindrical bodies are set within a range where the jets ejected from the water lifting cylindrical bodies 1 do not collide against each other before arriving at a photic zone or thermocline 6.</p> |
