DAF system used in enhanced biological tertiary treatment

Jorsun's DAF system is specially designed for enhanced biological treatment.

                      DAF used in enhanced biological tertiary treatment

Solids and other particulates preferentially attach to the air bubbles and rise to the surface of the dissolved air flotation unit where they are collected, thickened and removed by a motorised scraper. 

 

Using established solids/liquid separation technology, the units generate “whitewater” by dissolving air under pressure and then releasing the pressure to form micro air bubbles.

 

Main advantages

1. Extremely compact and efficient clarifier - with hydraulic loading upto 30 m/h.

2. Lower capital cost versus traditional rectangular units for equal flows.

3. Highly energy efficient - very high level of clarification with significantly lower pressurisation rate compared to traditional DAF clarifiers. 

4. Minimises polymer consumption by optimising flocculation with extended mixing time in presence of air bubbles and polymer.

 

Main applications

1 White water clarification and fibre recovery in the paper industry.

2 Clarification of de-inking effluents.

3 Clarification of food and industrial effluents in combination with physical-chemical treatment.

4 Biological tertiary treatment.

5 Landscape water treatment.
