Model Deepactor -Compact Wastewater Treatment System

A biological process is regarded as an useful and widely adaptable wastewater treatment system because of the low-running cost and the eco-friendly trait.
But, despite of the benefits, It has various problems to dissolved.

• Whereas the high BOD of the wastewater, the saturation solubility of the oxygen in water is very low as an example, 8.8ppm only at 20?.
• It is very hard to exist air bubbles in water with stable, because the big gap of the specific gravities and the high surface tension of the water.
• General process of the oxygen feeding to a biological reactor is the bubbling method using a blower and diffuser.
• When the air bubbles fed into the water, the mixture rise up rapidly and most of the air waste out, and even the supersaturated oxygen water reduce down to saturation condition quickly.
• Especially, when the depth of the bioreactor deeper, the load of the blower is rise upped, eventually the depth of the bioreactor is limited to 5~6m.
• As the results, this system spent blown air, lies low dissolved oxygen conditions and requires wide ground area relatively.

• Because of the diffusers lay on shallow position, less energy required for air charging
• Because of the highly pressed oxygen water file-up to upwards, the water maintains
  it’s saturated concentration → It makes biological activities rise up
• Because of the deep depth reactor operation, can be reduce down the facilities site area
