Dissolved Air Flotation

Dissolved Air Flotation

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 bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.

DAF (Dissolved Air Flotation) is used extensively in many industries including:

  • Food Industry
  • Meat Industry
  • Road Tanker washing
  • Paper Mills
  • Industrial Water Treatment.

 

Water-Treatment-dissolved air flotationA Primary coagulant is generally used to de-stabilize any colloidal material before the addition of a high molecular weight polymer.

The resulting sludge is then skimmed off the water’s surface and either goes for further de-watering or can be tankered away.

 

 

Process Description for Dissolved Air Flotation

The feed water to the DAF float tank is often (but not always) dosed with a coagulant (such as ferric chloride or aluminum sulfate) to coagulate the colloidal particles and/or a flocculant to conglomerate the particles into bigger clusters.

dissolved air flotation plant

 

A portion of the clarified effluent water leaving the DAF tank is pumped into a small pressure vessel (called the air drum) into which compressed air is also introduced.

This results in saturating the pressurized effluent water with air.

The air-saturated water stream is recycled to the front of the float tank and flows through a pressure reduction valve just as it enters the front of the float tank, which results in the air being released in the form of tiny bubbles.

Dissolved Air Flotation Process

 

Bubbles form at nucleation sites on the surface of the suspended particles, adhering to the particles. As more bubbles form, the lift from the bubbles eventually overcomes the force of gravity.

This causes the suspended matter to float to the surface where it forms a froth layer which is then removed by a skimmer.

The froth-free water exits the float tank as the clarified effluent from the DAF unit.

Some DAF unit designs utilize parallel plate packing material (e.g. lamellas) to provide more separation surface and therefore to enhance the separation efficiency of the unit.

Coagulants

Chemical Coagulants For Wastewater

Flocculation and coagulation treatment chemicals are used in effluent water treatment processes for solids removal, water clarification, sludge thickening, and solids dewatering.

Coagulants neutralize the negative electrical charge on particles, which destabilizes the forces keeping colloids apart. Water treatment coagulants are comprised of positively charged molecules that, when added to the water and mixed, accomplish this charge neutralization. Inorganic coagulants, organic coagulants or a combination of both are typically used to treat water for suspended solids removal.

Coagulants
Coagulation in process

When an inorganic coagulant is added to water containing a colloidal suspension, the cationic metal ion from the coagulant neutralizes the negatively charged electric double layer of the colloid. Much the same occurs with an organic coagulant, except the positive charge most commonly comes from an amine (NH4+) group attached to the coagulant molecule.

GPC Clear Solutions Limited can supply both organic and inorganic coagulants depending on your application requirements. Please ask our team about our GRAS approved products if required.

 

 


At GPC Clear Solutions Limited, we aim to offer the best quality coagulants at competitive prices. Our range of coagulants includes:

  • Organic primary coagulants (including polyamines and PolyDADMACS)
    These are high cationic charged products that are needed to de-stabilise the negatively charged colloidal particles and they promote rapid floc formation. They also have low molecular weight and viscosity to ensure complete distribution and mixing of the polymer in the water. Organic primary coagulants are available in 25KG kegs or 1000 Litre IBC containers. The majority of our organic coagulants are GRAS approved.
  • Inorganic primary coagulants
    These include a wide range of PAC based products, Ferric Sulphate and Ferric Chloride. Inorganic primary coagulants are available in IBC containers or by tanker delivery.
  • Inorganic/organic primary coagulant blends
    We can supply a range of inorganic/organic blended coagulants that can effectively treat a wide range of industrial effluents. They are all less pH dependant than inorganic coagulants and produce lower sludge volumes. The products can be dosed, undiluted as a single treatment or in conjunction with a flocculant to produce flocculation. Separation can be either by flotation or settlement. These blends are available in 25KG kegs or 1000 Litre IBC containers.
Removal of Suspended Solids and COD
You coagulate and flocculate effluent to remove the suspended solids from wastewater at the end of a manufacturing process. The Coagulant changes the electrical charge of the suspended solids so they start to attract each other to form small particles. Flocculation brings these small particles together to form flocs, using mechanical processes (eg DAF) these flocs can be made to either rise or fall to allow them to be removed from the wastewater. Once these suspended solids and the COD values associated with them are removed, the clean effluent can then be let to sewer, potentially saving your company thousands of pounds annually in trade effluent charges.
