Dissolved Air Flotation System for High COD Oil grease industrial wastewater

Dissolved Air Flotation System for High COD Oil grease industrial wastewater

Oil and Grease: remove 70—90% of input
Suspended matter: remove 50—80%
COD: low down 40%

DAF System Including: Reaction Tank, Dissolved Air Tank, Dissolved Air Pressure Pump, Control System, Agitator, Slag Scraper, Pipes and Fitting, Ladder and Fence, Dosing System

Description:
The DAF System , high efficiency dissolved air flotation machine is composed of high efficient air dissolving system and designed according to the new-generation of solid-liquid separation technology, which make the Hinada dissolved air flotation equipment (DAF) very efficient in removing organic and inorganic suspended matters, flocs, phosphorus (p), oil and grease from industrial wastewater such as oil refining, chemical industry, brewing, vegetable oil production and refining, slaughtering, electroplating, printing and dyeing.

    General Description

    The Dissolved Air Flotation (DAF) system is a highly effective water clarification process that uses millions of tiny air bubbles to separate and remove suspended solids, oils, and other contaminants from water and wastewater. Its primary goal is to produce clean water and a concentrated, easy-to-remove waste product (sludge)

    Dissolved Air Flotation Machine Specification

    Hinada the leading manufacturer of DAF System for industrial wastewater treatment according to project requirement. To make the suitable proposal, we need know more details of project included: capacity, wastewater source,wastewater quality (SS,BOD,COD,FOG etc ).

    Dissolved Air Flotation System main feature

          DAF System Application 
    Application Industry Primary Contaminants Removed
    Municipal Treatment Suspended solids, organic matter, phosphorus
    Drinking Water Treatment Algae, low-density particles, natural organic matter (NOM), turbidity
    Food & Beverage Fats, oils, greases (FOG), suspended solids, organic loads (BOD/COD)
    Pulp & Paper Fibers, inks, fillers from paper recycling and production processes
    Oil & Gas Oil droplets, suspended solids (often uses nitrogen in a DGF system for safety)
    Mining Heavy metals, minerals, fine particles
    Marine & Aguaculture Algae, fine solids in ballast water and fish farming operations

    DAF System Benifits

    Dissolved Air Flotation System with the purpose to reduce and remove or low down the COD, TSS and FOG from industrial wastewater.  The DAF system utilises fine air bubbles, also known as ‘White Water’, which attach themselves to the suspended material within the waste stream, increasing buoyancy and floating them to the surface. The floated solids are then removed by a simple but effective scraper mechanism. More often than not chemical conditioning is used to increase the effectiveness of the Dissolved Air Flotation process.

    The Dissolved Air Flotation process uses the most reliable and positive method of producing air bubbles of the optimum size. This is done by dissolving air into water under pressure and then dropping the pressure on entry to the DAF cell using a controlled nozzle orifice. As the pressure is reduced, the air naturally comes out of solution in the form of micro bubbles.
