What is the purpose of flotation in water treatment?

Flotation in water treatment plays a crucial role in enhancing the removal of solids from water. This process involves the introduction of small air bubbles into the water, which attach to suspended particles. As these bubbles cling to the solids, they rise to the surface, forming a froth or scum that can be easily removed. This mechanism is particularly effective for separating fine particles that may otherwise remain suspended in the water. It improves the efficiency of solid removal beyond traditional sedimentation methods, allowing for clearer water and better overall treatment performance.

This process is typically utilized in various water treatment facilities, especially in the removal of organic matter and other particulates, making it significant in ensuring water meets safety and quality standards prior to distribution or further treatment.
