Our Dissolved Air Flotation DAF units use a pressurized stream of water to deliver dissolved air to an incoming wastewater treatment stream that contains flocculated waste. When the pressure of the dissolved air and water stream is reduced, the air effervesces out of the water and attaches itself to the waste particles.
GRAPHIC DESCRIPTION OF PROCESS UNITS The main objective of primary treatment is to reduce the concentration of suspended solids from wastewater. The basis of this reduction is to calm water in a tank (reducing water flow velocity) so that solids with a density The dissolved air flotation (DAF) is a kind of induced flotation

VanAires dissolved air flotation systems help our customers save money by reducing TSS, BOD, and FOG discharge levels, therefore reducing surcharges, increasing byproduct recovery, reducing loads on lagoons and secondary treatment facilities, and preventing costly expansions of secondary treatment facilities.
Innovative Use of Dissolved Air Flotation with Biosorption as Primary Treatment to Approach Energy Neutrality in Biosorption, Captivator 174; System, Dissolved Air Flotation, Energy Neutral, Primary Treatment INTRODUCTION dissolved air flotation (DAF) is used to improve solidliquid separation after the biosorption
Primary Dissolved Air Flotation (DAF) Tank The primary DAF is designed to remove gross inorganic, colloidal content as well as some hydrocarbons (identified in the analysis as Oil amp; Grease) which may be inhibitory to the sensitive anaerobic process. pH adjustment utilizing acid/alkali is also completed at this step in preparation for digestion.
The Dissolved Air Flotation technology (DAF) has proven to be very successful as a pretreatment step. Nijhuis flotation systems have been developed since the 1970s and our units stand out as the best in its field.
The Dissolved Air Flotation (DAF) process has been used extensively for wastewater treatment to remove suspended matter from waste streams such as fats, oils, and grease (FOG), total suspended solids (TSS) and insoluble BOD. bioprocessh4O provides a complete line of bioDAF units along with ancillary equipment for captial purchase,

Ozonation, sorption to granular activated carbon and aerobic degradation were compared as potential treatment methods for removal of dissolved organic carbon (DOC) fractions and selected organic compounds from shale gas flowback water after pre treatment in dissolved air flotation unit.
Startup and Performance of the Worlds first Large Scale Primary Dissolved Air Floatation Clarifier Bruce R. Johnson1*, Jennifer Phillips2, Primary Treatment, DAF, Dissolved Air Floatation, Cothickening Effluent from the flocculation chamber goes to the primary dissolved air flotation (DAF) clarifiers, prior to entering the
Dissolved Air Flotation is the preferred option for primary treatment where the contaminants are fine suspensions, colloids, oil and grease and flocculable colour. Depending on the fraction of suspensions and oil grease that exert BOD, reducion efficiency of BOD in the range of 25% to 90% is achievable.

Dissolved Air Flotation CPF/PWF type The CPF and PWF flotation units are compact built flotation units which are suitable for the treatment of normally polluted wastewater. The CPF and PWF units are designed to get a complete laminar flow through the unit in combination with a small footprint.
Dissolved Air Flotation is best suited for food related applications. The VLT series DAF (Dissolved Air Flotation) system is arguably one of the best DAF systems on the market. The VLT is defined by its smaller footprint, lower cost for a given flow rate and extremely high efficiency.
Dissolved air flotation (DAF) has gained widespread usage over the last forty years for the removal of suspended solids (TSS), oils and greases (Oamp;G), and biochemical oxygen demand (BOD) from wastewater and other industrial process streams.
Dissolved Air Flotation CPL/PWL type. The flotation unit consists of a flotation tank equipped with the special quot;low frictionquot; inlet compartment, an aeration system and a sedimentation discharge system with sludge compartment. The wastewater (after primary treatment) is pumped into the aeration basin, which is filled with an activated

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny
