    Abstract

    Aeration process is a process to increase the solubility of oxygen in the water to removal organic materials contained in wastewater. Aeration process has several types, one of them is tray aerator. The aim of the research to increase the dissolved oxygen in the water with the use of Micro Bubble Generator (MBG) as the aeration process. The effectiveness of MBG will be examinated by analysis of DO that showing of dissolved oxygen in the water. The research activities carried out by using water as a water sample, rectangular contactor, the water supply from the water pump with a suction head of 9 meters, discharge head of 24 meters and a total head of 33 meters with a 220 volt / 50Hz / 1HP and 2850 RPM. The Supply air injection using a compressor which has a volume of 7 liters and 220 volts / 0,75HP / 2850 RPM. Several variations of the detention time is used 0,5,20,35 and 50 minutes. Flow rate was used 0.00018, 0.00014, 0.00013 and 0.00007 m3 / s, and the pressure was used 13 Psi, Psi 8, 6 and 3 Psi. Then Dissolved Oxygen was measured to determine the effectiveness of the MBG in aeration process. The result of research was that the smallest pressure with the smallest flow rate and at 35 minutes, a very significant increase in dissolved oxygen. While at the same flow rate and pressure and the detention time of 50 minutes, the increasing of dissolved oxygen in water was no significant. This condition was caused aeration process on saturated conditions. It concluded that the flowrate 0.00007 m3 / s and pressure 3 Psi formed micro bubbles regime. was used 0.00018, 0.00014, 0.00013 and 0.00007 m3 / s, and the pressure was used 13 Psi, Psi 8, 6 and 3 Psi.
