The new AQUA-DAF dissolved air flotation systems combine the new hydro direct system and unique micro-bubble screening system to deliver clarification, separation and thickening efficiency. Available from CST Wastewater Solutions , the air flotation systems feature a high air dissolving rate (>90%) and help reduce energy footprint and chemicals consumption.
The QUA-DAF dissolved air flotation systems operate on the principle of the feed stream, clarified effluent and sludge float all being conveyed through the unique multifunctional central column. Both feed and clear streams follow similar radial trajectories and the feed mix is pushed immediately to the surface because of the floating action of the micro air bubbles. The specifically designed inlet slots allow the inflow to be evenly distributed throughout the flotation area (hydro direct system). Prior to reaching the exit slots, the clear bottom layer is forced to pass through a filtering micro bubbles bed provided by the high efficiency air-dissolving reactor. This unique system allows for an extra available flotation area and excellent separation performance.
Typical applications that use the new AQUA-DAF dissolved air flotation systems include:
- Sludge thickening
- Refinery oily wastewater treatment
- Paper industry: white water clarification / fibre recovery
- Surface waters clarification
- Algae removal
- Oil and grease removal
- Juice clarification
