Advantages of DAF Dissolved Air Flotation

Removes Contaminants Effectively

Removes more than 85 to 90% of suspended solids and 90 to 95% of oil or fat from treated effluent (wastewater). This exceeds all other methods for removing these contaminants available today.

Quick Removal of Contaminants

Small diameter air bubbles in our systems mean that contaminants are removed from treated water much faster than by other means, and that filtered effluent can therefore be provided to industries with quick response times.

Customizable Solutions

Companies can configure their systems to meet their specific needs i.e. for fitment in their facility (size: 1 to 500+m3/hr) or their means of shipment (truck, rail, or container).

Economically Advantageous

Our systems provide companies with low operating and maintenance costs, coupled with energy efficiency savings that provide an economic advantage for companies to produce treated effluent using our methods versus traditional methods of treated effluent production.

Yes, DAF Systems can meet all governmental requirements. All DAF Systems comply with ISO, CE, and Local Environmental Regulations. Additionally, Energy Saving Features (e.g. Variable Frequency Drives) lower our carbon footprint.

Is there a difference between DAF and Sedimentation?

DAF is most effective for lightweight particles, oils, and other time-sensitive applications since DAF systems separate materials quicker than sedimentation, while sedimentation is a better solution to separate heavier particles/sediments. We also provide hybrid DAF and Sedimentation treatment solutions.

How often do DAF Systems require maintenance?

DAF Systems require very little downtime; Typical maintenance includes the following: Daily: inspections of the pumps and skimmers. Weekly: Cleaning the nozzles and sensors. Annually: Professional servicing, which can be arranged through our Global Support Services.

Which industries utilize your DAF Systems?

What Our Clients Are Saying

Bruce

Through the use of DAF technology, we've found a way to decrease our oil removal cost at the facility 30%. The footprint of the DAF unit has proven to be advantageous to our facility due to limited space.

Sini

I am currently utilizing DAFs in my biodiesel processing facility for removing plug oils and greases from washing water. The sturdy stainless steel construction of these units supports the confidence I have, along with an 18-month warranty.
