Many clients using air flotation systems face a common challenge: how to properly handle the flotation residue. This article first explains the definition of flotation residue and its detrimental effects on air flotation, then proposes effective solutions. Simply put, flotation residue refers to the waste material generated in air flotation cleaning systems. It's crucial to prevent impurities in the residue from re-dissolving, as improper handling can reduce overall efficiency and even cause adverse effects.

In fact, the treatment of scum is aimed at improving purification efficiency, and it is essential to utilize the sucrose content in the scum rationally to prevent spoilage of its contents. Improper handling may lead to suboptimal results. During phosphorus treatment, the amount of scum is relatively low, and its processing is comparatively straightforward, requiring only a single suction filter.

In international technical practices for air flotation, the scum is typically recirculated into the mixed liquor for clarification treatment, as the calcium phosphate in the scum reacts with the flocculant. During the dilution process after scum formation, re-dissolution occurs. Moreover, the greater the dilution of the scum, the higher the re-dissolution content, which requires our attention.
