The Sedimentation Dissolved Air Flotation (SDAF) is an advanced DAF system. SDAFs are mostly used in the field of water purification. It combines Dissolved Air Flotation (DAF) technology with the sedimentation process for a more efficient separation of oil and solids from water. It is designed to remove suspended solids, fats and oils, BOD, COD and heavy metals from a wide range of wastewater sources.
The SDAF Advantages
Dissolved Air Flotation by itself has several process advantages over sedimentation – it can produce better water quality, and it can be operated at high surface loadings resulting in plants with relatively small footprint. It can also be started up quickly, with a steady water quality being achieved in a relatively short period of time. The solids concentration of the sludge produced is higher than that of sedimentation. The Enviro Concepts SDAF is therefore designed to not only merge the sedimentation process with the advantages of Dissolved Air Flotation, it is also engineered to achieve a smaller footprint and more efficient functioning of the treatment process itself.
Key benefits of the Enviro Concepts SDAF system are:
- High Productivity & Efficiency
- Small Footprint for easy transport and install
- Low Energy Consumption
- Advanced DAF technology: Enhanced oil water separation ability
- Factory Tested: Comes pre-assembled and wet-tested
- Customisable: The design of the system can be customised as per client specifications
- Huge savings in chemical dosing costs (15-30%)
The Enviro Concepts SDAF units are pre-engineered, pre-assembled and tested in our factory. They are skid-mounted or containerised and are easily transported and installed efficiently at client sites.
The Sedimentation Dissolved Air Flotation units are made of mild steel or stainless construction. They include mixing, flotation and sedimentation zones. They have a highly efficient dissolved air distribution system. The units come with sedimentation plate packs, mechanical sludge skimmer and non-clogging sludge weir. Package systems include chemical dosing system, flocculator, and feed, discharge and sludge pumps.
The SDAF can be applied to various industrial wash processes, food industry wastewater, grease trap waste treatment, Activated Sludge systems, sludge thickening, wastewater from wash bays of cars, trucks and mining vehicles.
