一种用于在通常高度饱和氢气的水体的下游电解产生氢气泡的方法；将氢气泡的气泡尺寸控制在100到600微米的范围内，从而使氢气泡起到载体的作用，将缺氧的水抬升到水面，但氢气泡基本上保留在靠近水体表面的水中，沿着其表面移动并沿着将如此携带的水暴露到自然曝气和阳光下的路径向外移动；气泡尺寸的范围是不附着固体材料并将它们携带到水面以消除浑浊和形成絮状物。
A method for generating hydrogen bubbles electrolytically in the lower reaches of a body of water which is normally highly saturated with hydrogen; controlling the bubble size of the hydrogen bubbles within a range of from 100 to 600 microns so the hydrogen bubbles function as a vehicle to raise the oxygen deficient water to the surface, but the hydrogen bubbles substantially remain in the water near the surface of the body of water, moving along the surface thereof and move outwardly in a path therealong exposing the water so carried to natural aeration and sunlight; the range of the bubbles size being such as not to adhere to solid materials and carry them to the water surface to eliminate turbidity and the formation of floc.
