Design notes

A pressurized recycle stream introduces dissolved air into the flotation zone.
Float removal and bottom-solids withdrawal are defined in detailed design.

Indicative process overview. Equipment tags identify functional blocks only. Final PFDs, P&IDs, duties, sizes, valves and instruments are developed from the approved project design basis.

PROCESS & EQUIPMENT DETAILS

How dissolved air flotation (daf) fits your process.

Operating principle

Flotation treatment for suitable suspended solids, fats and floatable contaminants.

Fine air bubbles attach to suitable suspended material and float it to the surface. Coagulation and flocculation may be required based on treatability tests.

A solution shaped by your requirements.

Flotation treatment for suitable suspended solids, fats and floatable contaminants. Treatment begins with understanding the effluent sources and their variability. Physical, chemical and biological stages are combined as appropriate, followed by polishing and sludge management.

What we review

Average daily flow and hourly inflow profile
Operating hours and peak-flow conditions
BOD, COD, TSS, pH, nutrients and relevant contaminants
Reuse or discharge objective
Available area, levels and site interfaces
Treatability, sludge handling and odour constraints

Capacity, materials, operating conditions and performance are specified after review of your project data. Product images are conceptual visualizations.

From design to operation

Our scope can cover process and mechanical engineering, manufacturing, supply, installation, commissioning and ongoing support. The final proposal clearly defines supplier scope, client interfaces, optional items and exclusions.
