Eco K Consult - Dissolved Air Flotation

The Eco-K-Consult team has over 18 years of experience in wastewater treatment with flotation units—their production, supply, and operation.
Dissolved air flotation (DAF) units provide a high degree of removal efficiency and serve as the main physico-chemical step in the technological scheme of a WWTP.

In the flotation chamber, floccules are formed by dosing primary and/or secondary flocculants, and all lighter undissolved substances contained in the wastewater are removed. Dissolved air flotation separates the liquid and solid phases, including activated sludge and other suspended particles.

Eco-K-Consult can offer installation supervision, start-up, and testing of dissolved air flotation systems.

Typical applications of dissolved air flotation in wastewater treatment include:

Petroleum industries and refineries
Manufacturers of machine parts with increased fat or oil content in wastewater
Galvanic processes
Textile industry
Canning factories – fruit and vegetable processing
Dairies – milk processing
Slaughterhouses and meat processing plants
Vegetable oil processing – oil production
Beer and alcoholic beverage production
Others
We also have extensive experience with associated technological equipment for DAF units, such as:

Automatic stations for preparing flocculant (polyelectrolyte) solutions—automatic or manual systems for working with dry granular or liquid emulsion flocculants
Dosing pumps for flocculant (polyelectrolyte) and coagulants
Aluminum chloride/sulfate, ferric chloride/sulfate, sodium hydroxide dosing systems
Collection tanks for floated substances (integrated in the DAF unit or installed downstream)
Pumps for floated substances—transport to a collection tank before a filter press, centrifuge, or decanter for sludge dewatering
Control equipment and other auxiliary systems
Sludge dewatering systems – filter presses
