Dissolved Air Flotation is the preferred option for primary treatment where the contaminants are fine suspensions, colloids, oil and grease and flocculable colour. Depending on the fraction of suspensions and oil grease that exert BOD, reducion efficiency of BOD in the range of 25% to 90% is achievable. Below is a comparison of DAF clarifier with conventional sedimentation clarifier:

1. Daftech clarifier has a retention time of 3 minutes against 2 hours in a sedimentation clarifier.

2. TSS removal of 98% is possible whereas in a conventional clarifier the average efficiency does not exceed 70%.

3. Oil removal down to 10 ppm is possible whereas in a conventional clarifier there is no possibility of removing O&G.

4. The higher efficiency of BOD removal in a DAF clarifier results in lower energy consumption in downstream biology.

5. Sludge consistency as high as 3 to 3.5% is achievable against 1 to 1.2% in a sedimentation clarifier.

6. Sludge flows by gravity whereas in a conventional clarifier sludge transfer would require sludge pumps.
