VanAire DAF®

Dissolved Air Flotation

The VanAire DAF design has a timeless approach to wastewater treatment; our exclusive aeration system combined with a durable design has outlasted even the closest competitors.

VanAire’s wastewater pretreatment DAF technology is the most effective and reliable in the industry. Our MicroAire aeration technology and clarifier design maximize the removal of TSS, BOD, and FOG in all industrial wastewater streams. All VanAire DAF units feature our proprietary Breakout Valve that precisely controls the micro bubble cloud.

Why VanAire DAF technology has stood the test of time

COST EFFICIENT

• Reduction in wastewater surcharges and further treatment expense

• Better energy efficiency—physical separation vs. biological treatment

• Reduction in chemical usage—smaller more abundant bubbles float a finer floc

• Cost efficient, in-house manufacturing

Features of a VanAire DAF:

Air Vent Valves

A ball valve is mounted on top of each Saturation Tank. They vent a small amount of surplus air to avoid turbulence caused by large bubbles in the DAF.

Saturation Tank Headers

Pump Discharge Pressure Gauge in foreground with Air Injection Rotameters and Saturation Pressure Gauges in background.

Rotameters

Injected air volume is adjusted and monitored with one Rotameter per Saturation Tank.

Modular Aeration Skids

Modular aeration skid, common to our 150gpm, 300gpm (shown), and 450gpm aeration units, has a footprint of “approximately” 6′ x 4′ and stands 6′ tall.

Pump and Motor Subassemblies

100GPM and larger aeration pumps and motors are mounted on a subassembly which is attached to the main aeration skid via three spherical washers to reduce external force inputs that influence pump and motor alignment.
