Waste Water Treatment

ASH (Air Sparged Hydrocyclone)

The Kemco ASH system achieves performance superior to that of conventional DAF (Dissolved Air Flotation) systems, and has a significantly smaller footprint and vessel. Designed to handle varying loads, it will save on initial equipment cost, installation cost, operating cost and space requirement, and it requires less maintenance.

Combining centrifugal separation with air flotation, Kemco’s ASH System produces efficiencies exceeding those in DAF’s and other wastewater treatment technologies in the removal of FOG (Fats, Oil and Grease), TSS (Total Suspended Solids) and BOD (Biochemical Oxygen Demand).


How it Operates

In the ASH, wastewater is subjected to cyclonic, sheet flow and placed into intense contact with air through a porous metal sparging element. In this way, waste constituents are readily removed from the bulk liquid stream due to the flotation as well as the cyclonic separation developed.

The ASH hydrocyclone is compatible with clarifiers – it is used in conjunction with a simple clarifier tank with mechanical skimmer to move the separated wastes to a sludge compartment. It is also compatible with chemical coagulation/flocculation systems, if needed, to provide enhanced separation of waste constituents.

The ASH provides separation of foams, such as Aqueous Film Forming Foam (AFFF) used in fire fighting, as well as other waste constituents from water. It does so in a compact, space-efficient system, which has been shown to be superior to other technologies such as Dissolved Air Flotation or membrane separation systems such as Reverse Osmosis (RO).

It is suited to waste streams containing any of the following:

  • AFFF and other foams
  • Oils & Greases (either free or emulsified)
  • Heavy metals, insoluble materials
