Dissolved Air Flotation (DAF) System

High-efficiency microbubble flotation for rapid removal of suspended solids, oil and grease from industrial wastewater.

High-Efficiency Solid Removal | Oil & Grease Separation | Compact Clarification

Physico-chemical separation using 20–80 micron microbubbles — coagulation, flocculation, air saturation, flotation and skimming in circular or rectangular configuration for rapid, high-efficiency removal of TSS and FOG.
