Dissolved air flotation machine

Dissolved air floation  is one kind of flotation machine, it uses water solubility in different pressures on different characteristics, all or part of the processed (or dealing with the water after pressure and gas, increase water quantity, the dissolved into the air with the water, coagulant in atmospheric cases release, the air bubbles, adhesion formation exudates in impurity, causing flocculent flocculant grain dense as water and whole grains, thereby rise solid-liquid separation.

Adopting new efficient air-entraining equipment - tiny bubbles generator, instead of traditional air-entraining equipment to the water, and in floating range region inclined pipe installation, including some of slag enclosure, scraping feeders machine, spiral out composed a complete floating water purification devices. Theoretically speaking, the treatment effect of air-float with retention time is not directly linked, with only about air-float area, if the water depth H for air-float area reduce water depth H / 10, then floating distance and retention time will narrow 10 times, this is the famous "shallow pool theory". Floating area to join the aim is to increase inclined pipe atmospheric float area, greatly reduces the Renault coefficient, contentious in turbulent state float avoid, manufacturing good laminar state, achieve the effect of shallow gas float. Similarly, when the density of suspended due to larger than 1, installed the inclined pipe group, can produce shallow pool precipitation, thus make the effect in the turbulent precipitation conditions. Size teach large, proportion of the difficulty of teaching big floating polluting substances would be concentrated to mud collecting in the area, achieve the purpose of pure water.

Dissolved air floation machine for papermaking wastewater treatment and fiber recycling, printing and dyeing wastewater treatment, electroplating, etc contain all sorts of heavy metal ion wastewater treatment, oily wastewater treatment, the leather making wastewater treatment, chemical wastewater treatment, paint wastewater treatment, food waste water treatment, the biological treatment of mud and water separation and low turbidity water treatment, including algae water treatment, a variety of other wastewater solid, liquid separation etc.
