Dissolved Air Flotation Systems (DAF) | Remove TSS, BOD
DAF applications for high capacities (High Rate i-DAF) above 4500 gpm for large scale water production facilities, such as a pre-treatment for surface and sea water. Containerized DAF ( ICFF ) system based on a plug and play principle , available in boxframe or container configurations ranging from treatment capacities of 25 to 600 gpm.
Dissolved Air Flotation system. The DAF water treatment process clarifies wastewater and is typically used in a wide range of industrial applications to maintain environmental compliance and mitigate the financial impact of trade effluent charges.. The system is used for the reduction of Chemical Oxygen Demand (COD) present in fat, grease, oil, colour organic matter, biological sludges, and
FloatPac™ Series Inclined Plate Style (DAF) System
Recycle / Air Dissolving System (RAD): The HydroFlo dissolved air flotation system comes standard with a recycle water air dissolving system rated at 50% of the DAF design flow, providing an air to solids ratio (A/S) of between 0.015 and 0.040 lbs air/lbs. solids. Standard models are designed for 100 psi, 100 degree F.
Water then flows into a DAF unit where the physical separation takes place. Sometimes the DAF process designer opts for a plate pack DAF system and other times for an open tank DAF unit. When each DAF system is used is an interesting discussion. Separated solids flow out of the DAF system as sludge.
How Dissolved Air flotation Systems for Water Treatment
Dissolved air flotation (DAF) is a water treatment process for removing oils, solids, and greases from a water supply. The process helps clarify wastewaters by eliminating different types of suspended matter. DAF dissolves air in pressurized water – then releases it at atmospheric pressure.
Dissolved Air Flotation (DAF) systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD 5), and oils and greases (O&G) from a wastewater stream. Contaminants are removed through the use of a dissolved air-in-water solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent.
Dissolved Air Flotation Systems
Dissolved Air Flotation systems effectively remove TSS, FOG, and other pollutants from wastewater. Conceptually, the DAF process is simple – tiny bubbles attach to solid contaminants causing them to float and then sludge is skimmed off the surface of the water – but designing a DAF system for a real-world application isn’t quite as simple.
