The titanium disc aerator is a common gas-liquid mass transfer device, and its operational principle is based on the mass transfer of gas in a liquid medium. By introducing compressed air or oxygen from the bottom or side into wastewater, it forms bubbles and disperses them into the water, thereby increasing the oxygen content in the water and promoting microbial growth and the degradation of organic matter in wastewater.
The operational principle can be summarized in several key steps
Gas Delivery
Compressed air or oxygen is delivered to the bottom or side of the titanium disc diffuser via a pipeline system.
Bubble Formation
When gas enters the water, bubbles form at specific structures or holes in the titanium disc diffuser. These bubbles subsequently rise through the liquid.
Bubble Dispersion
During the ascent of bubbles, the special design and structure of the titanium disc help effectively disperse the bubbles into the water, creating turbulence and gas-liquid exchange.
Oxygen Transfer
The dispersion of bubbles in water increases the oxygen content, elevating the concentration of dissolved oxygen. This aids microbial activity in biodegradation, effectively promoting the decomposition of organic substances in wastewater.
Cyclic Process
The diffuser continuously delivers gas and generates bubbles. Through a continuous cyclic process, it consistently supplies oxygen to sustain the normal growth of microorganisms and the treatment of organic matter in the wastewater treatment system.
