Purified water flotation method is the current international newer water treatment technology. The principle is the introduction of a large number of tiny bubbles in the water, by surface tension bubbles adhered to the fine suspended solids, a specific gravity less than the formation of the overall situation, according to the principle of buoyancy of the water, solid-liquid separation, to purify water. Traditional DAF structure due to a fatal design flaws on the processing power is low, water remaining in the flotation time to be 40-60 minutes, the device volume is very large, and the purification rate is very low, has been eliminated. Ultra-efficient shallow flotation water purifier is the emergence of a major breakthrough flotation waste water treatment technology. It was renamed stand water, dynamic water dynamic water, static water, the use of "zero-speed" principle, so that the flotation body in a relatively static environment vertical float to the surface, floating away minimized, and not affect the water flow rate Theoretical pool depth only about 450mm, only 3-5 minutes residence time in the water flotation machine, greatly reduced equipment size. Coupled with bubbles evenly distributed, no flotation dead zone, scraper means water disturbance etc, purification rate increased significantly. The successful development of ultra-efficient shallow ZCQJ ion flotation machine flotation is another major breakthrough in water purification technology, and make a qualitative leap. This product is based on the ultra-efficient shallow flotation made many significant improvements, mainly using a highly efficient means of each dissolved gas balancing energy dissipation and efficient system of special structure. The theoretical maximum rate dissolved air and no concentration gradient. Sixtus calculated according to Fox formula measurement, micro-bubble average diameter of only about 1um, compared with the current domestic and international level 20-50um at least reduced by 20 times, that is, when dissolved gas equal to the total surface area increases microbubbles least more than 400 times. In fact, since a substantial increase in the rate of dissolved air micro-bubbles or bubble density increases the total surface area of ??thousands of times. Foreign scholars showed that: when a diameter smaller than the diameter of the microbubbles after, according to the statistical mechanics, the impact force of its thermal motion of water molecules surrounding the loss of balance, the bubble will participate in part of the Brownian motion is extremely conducive to the spread of bubbles of oxygen molecules to sewage thus aeration effect will be higher than much more than a thousand times! On the other hand, the ionization of the dissolved contaminants, is a reversible reaction in dynamic equilibrium under the polar water molecules and surrounded by an electric double layer suspended organic matter will promote ionization, and high density, small diameter air bubbles, in It will lead to reversible reaction toward the production of a compound offset to some extent. Plus some mechanism is not entirely clear, ZCQJ ultra-efficient shallow flotation machine not only for the removal of ions suspended solids of 99.8%, and the solubility of COD removal of up to 45% -73%, is currently having the international advanced level of ion flotation machine. ZCQJ ultra-efficient shallow ion flotation machine has another big advantage: Because the microbubbles small diameter, high density, can fully capture the very fine suspended solids, without prior condensate as they gather a lot of alum , it can greatly reduce the dosage, and in some situations may not even run administration, greatly reducing operating costs.
