DISPERSED AIR FLOTATION (DAF) FOR FOOD AND PROCESSING INDUSTRY

KEE LAUNCH NEW MICROFLOAT DISPERSED AIR FLOTATION TECHNOLOGY TO REDUCE POLLUTION - KEE has introduced improvements to effluent treatment technology in a bid to minimise environmental pollution from wastewater.

Many industrial processes, particularly food processing, drinks/brewery and dairy, generate a large volume of effluent that is discharged into the sewer. The raw wastewater has high biological oxygen demand (BOD), high chemical oxygen demand (COD) and Fat, Oil and Grease (FOG).  To reduce environmental pollution, companies often pre-treat the wastewater before the wastewater is discharged into the sewer.


Until now, a system known as Dissolved Air Flotation (DAF) has been used to do this. The DAF system uses a high-pressure pump and venturi system to dissolve air into the wastewater. The solution of air and water is stabilised in a pressure vessel under high pressure.


A stream from the pressure vessel is discharged into a separating (settling) vessel, where the air comes out of the solution and is released as a fine bubble spray. These bubbles reduce the pollutants by floating them to the surface where they are removed.


The new KEE Microfloat system achieves the same result without the need to use a high pressure pump and venturi. Instead, it incorporates a patented system from Aeration Industries, which uses a low-power motor. A specially designed propeller disc on the aerator’s shaft produces extremely fine bubbles and transfers these 10-50µm air bubbles into the water through special ejectors.


The conventional DAF system uses a high-pressure pump and venturi system to dissolve air into the wastewater. The solution of air and water is stabilised in a pressure vessel under high pressure. A stream from the pressure vessel is discharged into a separating vessel where the air comes out of solution and is released as a fine bubble spray. These bubbles greatly reduce the pollutants by floating them to the surface where they are removed by equipment designed to remove the floating layer.


The new KEE Microfloat system achieves the same result without the need to use a high-pressure pump and venturi. Instead, it incorporates a patented system from Aeration Industries that uses a low-power motor. A specially designed propeller disc on the aerator’s shaft produces extremely fine bubbles and transfers these 10 to 50 micron air bubbles into the water through special ejectors.


The whole system is mounted in the circular flotation tank.


Some major advantages of the Microfloat system are that it:


- Removes in excess of 90% of fats, oils and grease (FOG).


- Substantially reduces the BOD and COD of the effluent.


- Eliminates the need for fine screens either before or after fat traps.


Dawn Meats in South Wales recognised the advantages of the new Microfloat system and commissioned KEE to build the first Microfloat system in the UK.


The KEE Group of Companies is committed to providing a customised approach to domestic, commercial and industrial wastewater treatment applications. With over 40 years’ experience in the development, design and manufacture of equipment, KEE has installed more than 350,00 solutions worldwide.
