What role does a bubble curtain play in the floatation treatment process?

A bubble curtain is employed in the flotation treatment process primarily to enhance the separation of floatable materials from wastewater. By introducing a series of air bubbles that rise to the surface, the bubble curtain effectively captures and lifts these suspended materials, such as oils, greases, and other light solids, to the water's surface. This rising action allows for easier removal of the floatable contaminants, resulting in a more effective treatment of the wastewater.

While other processes may involve filtration or adjustments to temperature and oxygen content, the specific function of the bubble curtain in flotation treatment centers around its ability to mobilize and concentrate floatable materials at the surface, which can then be skimmed off for further processing or disposal. This mechanism plays a crucial role in improving the overall efficiency of the flotation treatment system.
