Environmental Protection DAF Device Flotation Process In Wastewater Treatment

DAF Dissolved Air Flotation Device Environmental Protection Equipment

Cheneng MPF Dissolved Air Flotation Clarifier is suitable for wastewater streams containing solids, oils, and greases, which are difficult to settle or have a tendency to float. With proper chemical conditioning we remove colloidal and emulsified materials. Complete pretreatment systems can be supplied.

DAF is a high efficiency dissolved air flotation (DAF) unit with applications including sludge thickening, wastewater clarification and oil and grease removal.

Excellent performances are achieved thanks to the circular low head geometry of the cell, the innovative hydrodynamics of fluids in both entering and exiting the cell, and the proven efficiency of the floating sludge removal system.

The performance of the DAF flotation unit is superior to that of similar or alternative technologies both as a clarifier of primary or secondary effluent waters and as a thickener for biological sludge.

The system features a micro-bubble screening system, which results in high efficiency clarification and displays a high degree of operational reliability.

Typical applications
• Primary / secondary clarification in wastewater treatment plants
• Sludge thickening
• Refinery oil wastewaters treatment
• Paper industry: white water clarification / fibre recovery
• Surface waters clarification
• Algae removal
• Oil and grease removal
• Juice clarification (winery and beverage industry)

Optional features
• Construction in 316 and other stainless steel grades
• FRP / titanium construction for special applications
• Installation into an existing / new concrete basin
• Sludge blanket thickness control system
• Tank coverage
