40–50 m³/h Dissolved Air Flotation Water Recycling System
The dissolved air flotation water recycling system is a high-efficiency wastewater treatment unit designed to separate oils, grease, and suspended solids from water. It operates by dissolving air into pressurized water and releasing microbubbles in the flotation chamber, which attach to impurities and float them to the surface for removal. This system is widely applied in industrial and municipal water reuse processes, ensuring stable clarification performance for facilities requiring continuous and reliable water recycling treatment.

Water Recycling System Product Introduction
The dissolved air flotation water recycling system is an advanced solid-liquid separation equipment used for wastewater clarification and reuse applications. It integrates pressurization, air dissolution, flotation separation, and sludge removal into a continuous treatment process. Designed for handling oily wastewater and fine suspended particles, it improves water quality for reuse or discharge compliance. The system is suitable for industries such as food processing, petrochemical production, manufacturing plants, and municipal utilities that require efficient recycling of process water and stable removal of contaminants under variable operating conditions.
Working Principle
The system works by dissolving air into water under high pressure to create a supersaturated solution. When released into the flotation tank, the pressure drop forms microbubbles that attach to suspended solids and oils. These particles rise to the surface as scum and are removed by a mechanical scraper. Heavier solids settle in the inclined plate zone and are discharged to sludge collection systems, while clarified water exits through the outlet for reuse or further treatment.
