Application of swirl type microbubble generator in artificial wastewater treatment
Keywords:
Microbubble generator, Artificial wastewater treatment, Water flowAbstract
A microbubble generator (MBG) produces tiny air bubbles that remain suspended in water for extended periods. This study investigates the use of MBG to enhance wastewater treatment by increasing dissolved oxygen levels, which are crucial for bacterial breakdown of organic pollutants. The experiment involved varying water discharge (QL) from 40 to 60 Lpm and air discharge (Qg) at 0.5 and 1 Lpm. COD (chemical oxygen demand) was measured to assess treatment effectiveness. Results showed that increasing QL with constant Qg enhanced air transfer and dissolved oxygen, leading to faster COD reduction. Increasing Qg at constant QL increased both bubble size and number, also improving oxygenation, but not as significantly as increasing QL. This highlights the importance of water flow in maximizing the benefits of MBG for wastewater treatment.
