Municipal Water Treatment

Nanobubble technology in wastewater treatment is an effective technique owing to its special characterization of bubbles, such as small-sized gas bubbles, higher surface area, slow rising velocity, negatively charged zeta potential, generation of free radicals, stability, and as a result the immense possibility of successful adhesion to the suspended particles. Applications of Nanobubbles in wastewater treatments entail higher mass transfer rates that lead to a high percentage of treatment using air, oxygen, and ozone.

Nanobubbles increase mass transfer when more stabilized small-sized bubbles are used. They successfully remove organics, inorganics, oil, color, fungi and bacteria, heavy metals, total nitrogen, and total phosphorus present in wastewater.

The nano-bubble technology can be integrated into processes of improving and increasing the effectiveness of the treatment in WW treatment plants, from the preliminary treatment stages, through improving the aeration processes to the stages of disinfection and treatment of effluents and sludge. In addition, nanobubble technology also enables the treatment of hazards in pumping, accumulating and transmission sewage systems.
