- Rapid industrial development tends to have a negative impact for environtment if not accompanied by post-industrial waste management. Water as one of the industrial waste must remain kept clean because it has an important role for the life of every organism. Moreover, the increasing population growth becomes a paradox for the quality of the availability of clean water. In this research, observation of the effects of microbubble generator (MBG) configuration arrangement on DO (Dissolved Oxygen) levels and effective working time trend analysis of the pump on wastewater treatment system. Types of microbubble generator used are the orifice and porous pipe. This research was conducted in a Wastewater Treatment Plant (WTP) measuring 3 m x 3 m x 1 m with 3 kinds of configurations and 8 pieces of MBG on each configuration. Applying condition of QL 16 m3/hr and QG 0.5 L/min with a pump system 30 minutes on and 45 minutes off. 4 DO meter placed at 4 particular points for the measurement of DO levels in the water. The purpose of this research was to determine levels of scattered DO in the water in order to meet the BOD (Biological Oxygen Demand) required by aerobic bacteria to keep them alive. Bacteria will be in charge of reducing the levels of COD (Chemical Oxygen Demand) in the wastewater. The results showed that each configuration is capable of producing a uniform value of DO in the entire pool area. The arrangement of the configuration with the tendency to bubble coalescence low will increase the value of DO levels and configuration III is the most optimal DO levels of 7.85 mg/L so that the configuration can be adopted as an alternative to industrial wastewater treatment.
