  • How Does Air Dissolve in An Air-dissolving Tank?
    The two most abundant gases in the air are N2 and O2, both non-polar gases. Such non-polar molecules with very low solubility must exist in the gaps between water molecules, so gap filling is a way for air to dissolve in water. In addition, we know that as the temperature increases, the amount of gas dissolved in water decreases, so it is also believed that there is a chemical reaction between water molecules and gas molecules called hydration.   Read More>
  • Factors Affecting The Effect of Pressurized Dissolved Air Flotation on Water Purification
    This paper combines theory with experiment to systematically analyze the mechanism of bubble generation by dissolved air method and how to generate miniaturized and large-scale bubbles. It also uses computer software to simulate and analyze the velocity field and pressure field of the fluid. Finally, it explores the effects of dissolved air tank pressure, releaser placement angle, and bubble rise height on the size and number of generated bubbles..Wuxi Yosun Environmental Protection Equipment Co.,Ltd   Read More>

The food and beverage industry creates large amounts of wastewater. This wastewater contains grease, solids, and organic matter. These components must be removed before the water can be reused or discharged. One way to treat this wastewater is with dissolved air flotation wastewater treatment.

Dissolved air flotation is a water treatment process. It is used to remove suspended solids from waste water. These solids float after being attached to small air bubbles. The process is simple. Air is dissolved in water under pressure. Then the pressure is released. Small bubbles form and rise. The bubbles stick to solids. Solids and bubbles float to the top. A skimming device removes them.

A lamella settling tank is a type of compact sedimentation equipment widely used in water treatment systems. It is designed with a series of inclined plates that allow suspended solids in the water to settle more efficiently. This system increases the settling surface area while keeping the tank footprint small. The design helps industries and municipal facilities reduce the load of suspended particles in wastewater without building large tanks.
