Biological treatment requires a large volume of oxygen to maintain appropriate activities of aerobic microorganisms; therefore, it consumes an extremely large amount of energy (electric power).
Fine bubbles have a characteristic of long residence time in water and excellent reactivity due to a large vapor-liquid contact area. By efficiently supplying oxygen, energy consumption can be greatly reduced.
In addition, the introduction of Tough Bubbler can reinforce local aeration in areas where dissolved oxygen is low and treatment is unsatisfactory.
Tough Bubbler can be easily installed, as retrofit/upgrade/supplemental measures, in an existing tank when a plant is running, without draining or removing existing equipments in the tank.
Introduction cases
Liquor manufacturing industry
As the wastewater treatment load increased with increased production, the aeration capacity needed to be enhanced. Due to space limitations, it was difficult to add a blower, so Tough bubblers, that also can be adjusted according to demand, were installed.
Food manufacturing industry
The diffuser in the aeration tank was damaged and dropped at three locations due to deterioration with age, so the aeration function was extremely poor in some places. There was also am issue with an offensive odor due to the progress of the decay of sludge that settled in the poorly aerated areas.
Auto parts manufacturing industry
Since the clogging of the air diffuser occurred frequently, the aeration had become so poor that wastewater treatment was unstable.
