Vortex air flotation machine

The vortex-type dissolved air flotation (DAF) unit is a wastewater treatment device that uses mechanical aeration to generate microbubbles, causing suspended solids, grease, and other impurities in wastewater to float to the surface and separate. Its core component, the vortex aerator, utilizes a high-speed rotating impeller to create negative pressure, drawing in air and breaking it into microbubbles of 20-50 μm. These bubbles combine with pollutants and float to the surface, where they are removed by a scraper. This equipment eliminates the need for dissolved air tanks and air compressors, consuming only 1/8 to 1/10 of the energy of traditional DAF units. It is suitable for oily wastewater, dyeing and printing wastewater, and food processing wastewater, achieving a COD removal rate of 65%-85%.

Main Features

High Efficiency and Energy Saving: Treatment capacity ranges from 5-320 m³/h, with electricity consumption of 0.1-0.3 kWh per ton of water;

Simplified Structure: No pressure dissolved air system, low maintenance costs;

High Adaptability: Can treat high-concentration wastewater (e.g., influent turbidity 1000 mg/L).

Application Areas

Industrial Wastewater: Oily wastewater from petrochemical and machinery processing industries;

Municipal Wastewater: Pretreatment of domestic sewage and hospital wastewater.
