High-performance solids separation for wastewater compliance.

Baldwin Industrial Systems designs and manufactures advanced dissolved air flotation (DAF) units for reliable removal of oil, grease and suspended solids.

Built in Australia and backed by decades of engineering experience, Baldwin DAF systems support water recycling, reduced disposal costs and consistent discharge compliance across industrial sectors.

How Dissolved Air Flotation Works

Simple process. Superior efficiency.

DAF treatment separates contaminants by dissolving air into wastewater under pressure.

When released, the air forms microbubbles that attach to solids, oils and greases, lifting them to the surface. A scraper system removes the accumulated float, producing clarified effluent.

Compared with sedimentation, DAF provides faster clarification, reduced chemical demand, and high-quality effluent, even under high-load conditions.

Why Choose a DAF Wastewater Treatment System?

Compliance, efficiency and reliability built in.

  • High-efficiency removal of oils, greases, algae and suspended solids
  • Consistent discharge quality for EPA and site requirements
  • Reduced energy and chemical consumption
  • Fast start-up and low-maintenance design
  • Compact footprint and modular configuration
DAF vs Sedimentation

The faster path to cleaner water.

ProcessDescriptionTypical Outcome
SedimentationUses gravity to settle solids at the base of the tankSlower; less efficient in high-load conditions
Dissolved Air Flotation (DAF)Floats contaminants to the surface via air microbubblesRapid separation and higher-quality effluent

For sites needing reliable throughput and compliance, DAF is the preferred solution.

Frequently Asked Questions

What is a DAF wastewater treatment system?

A DAF system removes suspended solids, oils and greases by releasing dissolved air into wastewater. Microbubbles attach to contaminants and float them to the surface for removal.

How does DAF differ from sedimentation?

DAF uses flotation rather than gravity, enabling faster solids removal and superior performance under high-load or variable-temperature conditions.

What industries use DAF systems?

Food processing, mining, manufacturing, recycling, wash bays, oily water treatment and other industrial sites requiring consistent discharge quality.

What accessories are available?

Coalescing separators, dosing skids, compressors, pumps, flocculation tanks and monitoring equipment to meet performance goals.

Can DAF systems be customised?

Yes. Each unit is built to site-specific flow rates, tank volumes, integration needs and compliance requirements.
