Dissolved Air Flotation (DAF), the use of micro bubble flotation as a solid liquid or liquid liquid (or both) separation method, is widely used in industrial and domestic wastewater treatment processes. Dissolved Air Flotation is a well established separation process that uses micro bubbles as a carrier phase to remove solids, ions.
Usters Water offers a complete line of dissolved air flotation (DAF) systems. Ideally suited for liquid solid separation in municipalities and many industries, including separation of free oils and grease. The DAF units are designed for effective removal of total suspended solids (TSS), biochemical oxygen demand (BOD) and fats, oils and grease (FOG).
The R5 DAF is a pre engineered, modular, and skid mounted dissolved air flotation unit with variable tank sizes, flow, and recycle rates. It provides a flexible, easy to install, and affordable solution for smaller municipal and commercial water and wastewater treatment operations, plant pilot testing, and backup for unexpected plant equipment.
Dissolved air flotation clarifiers operate effectively over a wide range of hydraulic and solids loading. DAF Corporation's FC Maximizer clarifiers can be used for treatment of reservoirs, potable water treatment, water reclamation, screening, sludge thickening and.
The VFDs are configured for the torque share operation mode. The panel enclosure is NEMA 4X with a side mount air conditioning unit to protect the control components in a wet, washdown environment. The HMI provides the press operational information in a graphical format to the operator and allows the adjustment of set points and parameters.
Air is delivered by the use of pressurized recycle flow. Tenco's proprietary recirculation system has been proven, by rigorous full scale testing, to dissolve air in water in excess of 87 saturation efficiency. This high efficiency minimizes the energy used to deliver the air necessary for solids flotation.

Dissolved air flotation is best applied to remove materials that normally settle slowly, persist by remaining in suspension, or have a tendency to float. Benefits of flotation are rapid process results – flotation happens immediately while sedimentation takes time, higher loading rates than gravity thickening, and fresher sludge solids.
The Komline Sanderson Dissolved Air Flotation Clarifier is designed for the removal of suspended solids or water immiscible liquids from process or wastewater to produce an effluent of high clarity and free of objectionable particles or liquid.
Description Dissolved air flotation (DAF) is a proven and effective physical chemical technology for treating a variety of industrial and municipal process and wastewater streams. DAF systems are commonly used for the removal of oils greases and suspended solids to meet a variety of treatment goals including Product recovery and reuse.
DAF (Dissolved Air Flotation) and ACE (Air Charged Entrainment) combined into one – attached and entrained air for higher separation efficiencies. Upgradable to a full ITS (Integrated Treatment System) – including upgraded control panel, chemical feed pumps, polymer make down system, flocculation tubes, pre wired and pretested as a complete wastewater treatment system.
The WORK of this Section includes providing equipment for dissolved air flotation thickener (DAFT) units for the concentration of mixed primary and secondary sludges and scums as follows float and sludge collection equipment suitable for a circular tank, drive equipment, access bridge, float troughs, air dissolution equipment including tank and backpressure valve, air compressors, pressurization pumps,.
This pork slaughterhouse facility had a 35 foot diameter dissolved air flotation thickener and an 11’ x 52’ rectangular DAF unit for wastewater pretreatment. FOX was hired to review the DAF performance and recommend improvements.
Jan 01, 1995 Recent applications of dissolved air flotation pilot studies and full scale design Tank design increases air water contact time and separated undissolved air to maximize air saturation. Operation efficiency of the eductor saturation vessel combination has been measured at 75 to 80 . Thus a flotation thickener will reduce sludge volumes.
Dissolved Air Flotation (DAF) Clarifiers and Thickeners Overview WesTech builds a complete line of Dissolved Air Flotation (DAF) and Dissolved Nitrogen Flotation (DNF) equipment for both municipal and industrial applications. The equipment incorporates many superior designs, both mechanical and operational. Dissolved Air Nitrogen Flotation is used in applications where the specific gravity of the.
Principal of Operation – Dissolved Air Flotation. DAF or Dissolved Air Flotation is a simple but ingenious concept. Make tiny bubbles by dissolving gas (air typically) into water under pressure according to Henrys Law of gas whereby the pressure applied to gas will dissolve it into liquid (water).
Dissolved Air Flotation Theory of Operation. If you are unfamiliar with basic DAF separator design principles, a review of the Dissolved Air Flotation Theory of Operation might prove helpful. This basic document covers Stokes' law and other basic separation concepts. General Considerations.
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. Heavier than water particles can also be made to float. Dissolved air flotation, the most common approach, works by attaching small bubbles of air to suspended solids. The bubbles are generated by saturating a recycled stream of water with air under pressure, then releasing the pressure rapidly to produce clouds of microbubbles.
Operation Principle of DAF Dissolved Air Flotation Machine DAF is a kind of air floatation. It uses the different solubility characteristics of water under different pressures to pressurize and aerate all or part of the water to be treated (or treated) to increase the air solubility of water. 188.8.131.52 The partial dissolved air floatation The.
