If you’re managing oily wastewater, high suspended solids, or variable mining or industrial flows, you need a system that performs consistently, without constant operator attention.
Our dissolved air flotation system range includes both standard dissolved air flotation systems and Sedimentation DAF (SDAF) configurations. These compact, factory-built units are purpose-built for demanding mining and utility applications where space, compliance and reliability are critical.
Designed for effective wastewater treatment, these systems remove suspended solids, fats, oils, grease, biochemical oxygen demand (BOD), chemical oxygen demand (COD) and heavy metals from challenging wastewater streams.
What is a DAF Dissolved Air Flotation System?
A DAF dissolved air flotation system uses pressurised air to create microbubbles that attach to fine solids and oils, lifting them to the surface for mechanical removal.
This form of dissolved air flotation water treatment is particularly effective when:
- Solids won’t settle in conventional tanks
- Wash bay water contains emulsified oils
- Wastewater loads fluctuate across shifts
- Downstream biological or membrane systems need protection
For mining and industrial operations, it provides a stable first stage of treatment before reuse, discharge or further polishing.
What Is a Sedimentation DAF (SDAF) system?
Sedimentation DAF combines high-rate settling with flotation in a single compact unit.
This allows the system to manage:
-
Mixed-density solids
-
Grit and heavier particles
-
Floating oils and greases
-
Variable inflows typical of mine site wash bays
Where wastewater quality changes daily, SDAF provides greater process stability than a conventional clarifier or standalone flotation unit.
Why mining and industrial clients choose our Dissolved Air Flotation systems
- Reliable removal of contaminants – handles total suspended solids, fats, oils and grease, biochemical oxygen demand, chemical oxygen demand, and heavy metals with ease.
- Compact footprint - engineered for tight plant rooms, retrofits, mining camps and space-constrained industrial sites.
- Fast installation - each DAF dissolved air flotation system is pre-assembled, and factory tested to reduce site labour, commissioning time and shutdown risk.
- Simple to operate - automated sludge removal and straightforward controls minimise operator input - ideal for sites without full-time water treatment specialists.
Common mining and industrial applications
Our dissolved air flotation water treatment systems are widely used in:
-
Mining and industrial wash bays
-
Mechanical workshops and panel shops
-
Food production and grease trap waste
-
Stormwater and groundwater treatment
-
Seawater pre-treatment for desalination
-
Sludge thickening and activated sludge support.
If your wastewater contains oil, grease or fine suspended solids, a dissolved air flotation system is often the most reliable first treatment step.
Built for stable operation and compliance
Installing a DAF dissolved air flotation system doesn’t just improve water quality, it reduces risk across your operation by:
-
Stabilising effluent quality
-
Reducing downstream chemical demand
-
Extending membrane and equipment life
-
Lowering sludge handling costs
It’s about protecting your assets and avoiding compliance issues before they happen.
