The bubbles are generally below 30um.
3. The DAF adopts a new high efficiency grid reaction structure, which has good
flocculation effect and power saving.
4. DAF with automatic control box, after debugging, normal operation without
special management, can achieve full automation.
Ⅱ、Application of DAF
DAF can be widely used in the treatment of industrial wastewater such as paper
making, printing and dyeing, electroplating, chemical industry, food, oil refining and
so on.
1. The fiber recovery rate of papermaking wastewater can reach about 95%, the COD
removal rate is above 85%, and the clean water can be reused completely.
2. The chroma removal rate of dyeing wastewater is about 90%, the removal rate of
COD is 60‐70%, and the removal rate of BOD5 is about 50%.
3. The oil from the refinery wastewater can be reduced to below 10mg/L, and the
wastewater can reach the level of clarification.
4. The COD removal rate of food, slaughterhouse and tannery wastewater is about
70%, and the chroma removal rate is over 94%.
5. When the content of chromium, zinc, copper, nickel and lead is below 50 ppm, the
removal rate of electroplating wastewater can reach more than 90%.
6. The bath turbidity of the big pool can be stabilized below 10 degrees, and the
bacteria in water can be removed more.
7. The turbidity of drinking water and industrial water can be delivered to less than 5
degrees, and has a good effect on reducing the color oxygen consumption.
8. The water content of the activated sludge can be reduced to about 97% by the
secondary common pond after the loanable biological treatment.
