Product introduction of 40 m³/h DAF Equipment
The 40 m³/h dissolved air flotation equipment is a prefabricated wastewater treatment unit designed for solid-liquid and oil-water separation processes. It is typically manufactured using carbon steel or stainless steel and delivered as a fully assembled modular system. The equipment is capable of handling influent with high suspended solids concentration and is suitable for medium to low density particles. It is widely used in industrial wastewater treatment, greywater purification, and pretreatment stages. This system is ideal for factories, processing plants, and environmental engineering projects requiring reliable clarification.
Working Principle
Wastewater is pumped into the system and mixed with air-saturated water to generate microbubbles. These bubbles attach to suspended solids, oil, and grease, reducing their density and causing them to float to the surface. A mechanical skimmer removes the floated sludge layer continuously. Meanwhile, heavier particles settle at the bottom and are discharged separately. The clarified water exits through the outlet, achieving efficient solid-liquid separation and improved effluent quality.
