Advantages of Dissolved Air Flotation Wastewater Treatment

Smaller Footprint

Requires less space than conventional equipment and takes up much less space than traditional sedimentation systems.

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.

Superior Quality of Treated Wastewater

Our treated effluent has a COD reduction of approximately 30 to 50%; so companies can produce treated effluent that meets even the most stringent discharge or reuse standards.

Assured Long-term Reliability

Provides customers with long-term assurance of the reliability of the equipment it operates and the ability to provide ongoing operational support including an on-site training, 24/7 phone support, and 18 months guarantee after purchase.

FAQ

If a DAF System fails, what are the procedures to be followed?

If a DAF system fails to operate correctly or at all, our 24/7 Global Support Services will diagnose the problem from the customer site or visit the customer site as required. Standard Warranty for DAF systems is for 18 months, and we can ship spare parts within 48 hours.

Are your DAF Systems environmentally friendly?

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.
