Pilot Dissolved Air Flotation Unit

By now you have searched high and low for a reliable pilot dissolved air flotation test unit for evaluation in your process plant. Search no further, Sciential’s pilot DAF unit features a revolutionary air saturation system that eliminates the need for ancillary equipment found in standard saturation systems (note the small footprint in the pictures to the right).

Unit Operation Of The Air Saturation System

Clarified wastewater from the DAF unit is recycled to the dissolved air flotation unit by an EDUR DAF Air Saturation System designed to operate at a pressure of 90 to 100 pounds per square inch (psi). Atmospheric air is dissolved into the recycle stream via the pump suction. Air flow to the pump is regulated by a needle valve rotameter.

As the air is introduced into the pump suction, a specially designed impeller shears the air into smaller air bubbles and under an increased pressure the air is dissolved into the clarified wastewater. This simplified unit of operation eliminates the need for an external air source (compressor), saturation tank, and air control panel, thus reducing space requirements, operation/maintenance, and capital equipment costs.
