Escava Dissolved Air Flotation


Our Escava system uses the Dissolved Air Flotation (DAF) process to separate suspended solids by addition of saturated air-water mixture which releases micro bubbles. These bubbles adhere to or enmesh in the suspended composite particles, which then rise to the surface due to their reduced density. A skimming operation removes the particles floated to the surface.


The systems removes total suspended solids (TSS); algae, fats, oils and greases (FOG); and associated biological oxygen demand (BOD) and chemical oxygen demand (COD) from a variety of water and wastewater.


With body construction from fibreglass, and manufactured to the highest standard of quality and workmanship, the Escava range will proven many years of reliable service.

AKS  carries ISO certification for 9001 Quality, 14001 Environmental Management and 45001 for OH&S Management.


With sturdy skid base, the Escava can be quickly maneuvered into place. Ensure you read the installation section of the Manual for complete information, if AKS is not installing the Escava for you.


Maintenance is significantly reduced with reduced confined-space servicing required due open top design and flush-out features. Ensure you read the Manual for complete information about routine Maintenance to make sure your Escava remains is optimum operating condition.
