Process Description of Dissolved Air Flotation
May 15,2023Read More
The air flotation process is an effective and fast method of separating solid particles from wastewater, which are designed to remove total suspended solids (TSS), biochemical oxygen demand (BOD), and oils and greases (O&G) from a wastewater stream..Here will introduce its application fields in detail.
The scope of oily wastewater is very wide, petrochemical, mechanical processing, food processing and other industries will produce a large number of oily wastewater. Oil and gas float method is mainly used to remove the emulsified oils.
Printing and dyeing wastewater has high color color and complex water quality. The ratio of BOD5 / COD is relatively low, so the printing and dyeing wastewater can be treated by air and float method. For the printing and dyeing wastewater containing sulfide and dispersed insoluble dyes, the effect of applying gas float method is remarkable.
Paper making industry is one of the industries with large water consumption, among which the white water produced by paper copying section accounts for about half of the displacement of the whole paper making process. Paper white water contains a large number of fiber, filler, rosin gum, etc., using gas floating machine to treat white water, not only can recover fiber, improve the utilization rate of resources, but also can make white water recycling, save water resources, reduce the discharge of waste water. According to the actual operation experience, the treatment of white water by air float is generally only 15~20min, with a short time, the removal rate of suspended matter is more than 90%, the removal rate of COD is about 80%, and the concentration of float residue is more than 5%.
Above all,we can know the air flotation unit is high-effective for the treatment of natural precipitation of emulsified oil and suspended solids with relative density close to 1. If you are worried about your wastewater treatment, trust the skid-mounted air flotation units will bring you nice experience!
