Saline DAF - Flotation Sedimentation System
SALINE DAF is an efficient flotation method for water clarification. The term refers to the method of producing flotation by dissolving air in the water under pressure and then releasing the pressure. When the pressure is released the solution becomes supersaturated with air as millions of small bubbles form. These bubbles attach to any particles in the water causing their density to become less than that of water. The particles then rapidly float to the surface for collection and removal, leaving the clarified water behind.
SALINE DAF systems are commonly used for the removal of oils & greases and suspended solids to meet a variety of treatment goals. SALINE DAF system is a proven and effective physical/chemical technology for treating a variety of industrial and municipal process and wastewater streams: wastewater, oil refineries, chemical plants and paper mills or food & beverage industries with many applications:
- Reduce – reuse – recover
- Pretreatment system before membrane treatment.
- Polishing of biological treatment effluent
- MBBR biological film process
- Aquaculture waste water (with specify Saline DAF for brackish water)
ADVANTAGES and CHARACTERISTICS
Recycle-Flow pressurization. Allows the system to operate at higher pressures and minimize the destruction of floc formed in the process flow. thereby increasing the effectiveness of the system.
Improved air saturation system. SALINE DAF uses 50-70% less recycle flow than conventional SALINE DAF systems while Introducing the same amount of dissolved air into the flotation tank.
Efficient DAF recycle pump. Designed to operate at high pressures increasing the amount of saturated air by 46% more than traditional centrifugal pumps.
Optimum use of coagulants and flocculants. SALINE DAF supports stronger floc formation. lower float volumes, and lower float moisture content thus allowing the system to operate with much lower air/solids ratio and higher solids loading rate.
Compact design. Due to Its high loading rate. The area needed for the SALINE DAF is approximately 15% of that required for a conventional clarification utilizing the space more efficiently.
Cost-effective. We deliver DAF pre-assembled and pre-tested in our controlled facility. often saving 50% or more over in-situ construction. SALINE DAF can also be Integrated into pre-engineered systems for increased savings and reduced schedule.
