The dissolved air flotation machine is equipped with a large-frequency motor, allowing it to treat large volumes of water efficiently. The air is introduced into the dissolved gas tank, facilitating effective separation of liquids. This professional-grade machine is ideal for industrial use, effectively transforming polluted water into a clean state.
QDEVU Air Flotation System can effectively remove the light flocs, flocculated colloidal substances, oil substances, etc. that are difficult to precipitate in wastewater,achieve the purpose of solid-liquid separation.
QDEVU Dissolved Air Flotation (DAF) System is a process to remove grease, oil and other fine suspended matter, reduce COD BOD,TSS to achieve maximum treatment efficiency in a compact footprint. It is able to remove a variety of contaminants to meet trade waste or reuse requirements. Each system is sized based on the hydraulic loading rate, Total Suspended Solids (TSS) and Fats, Oil and Greases (FOG) levels.
The DAF separates the suspended solids and lighter liquid contaminants (eg FOG and hydrocarbons) from the water by moving them to the surface of the DAF vessel and then scraping them off the surface. A pressurised stream of airsaturated water is mixed with the flocculated water and with the release of pressure, a cloud of very fine air bubbles carries the suspended solids and lighter liquids to the tank surface. Clean water overflows from the DAF tank, via an under/over-weir to sewer or to the next stage of the treatment process. The overflow level is adjustable and controls the level in the DAF flotation section. The sludge on the surface of the DAF is scraped into a sludge hopper by a mechanical scraper. The DAF system is automated via a programmable logic controller (PLC) mounted within a control cabinet on the system.
