Which high-rate process uses microsand?

The Actiflo process is a high-rate water treatment method that utilizes microsand to enhance the clarification of water. In this process, microsand acts as a seed material during the coagulation and flocculation stages. The microsand particles help to agglomerate the suspended particles in the water, promoting the formation of larger, denser flocs that settle more quickly during the clarification phase.

Using microsand in the Actiflo process allows for a significant reduction in the size of the treatment basin required, as the settling of the flocs can be achieved more rapidly compared to traditional processes. This efficiency, combined with the improved settling characteristics afforded by the microsand, enables the Actiflo system to treat large volumes of water in a compact footprint. This method is particularly effective in producing high-quality effluent and is commonly used in various water treatment applications.

Other processes, such as coagulation, lamella clarifiers, and dissolved air flotation, utilize different mechanisms and materials, without the specific addition of microsand as a key component for enhancing clarification.
