Dissolved air floatation is divided into shallow air floatation machine, concave air floatation machine, flat flow air floatation machine and so on. It is widely used in water supply, industrial wastewater and urban sewage treatment. The advantages of air flotation machine lie in its solid - liquid separation equipment with less investment, small area, high degree of automation, easy operation management and other characteristics. So how do you use it to make it work efficiently.

First, make sure that the water level of the equipment does not flood the packing layer or fall below the prescribed range. This prevents the intermediate zone from carrying too much undissolved air, thus keeping the effect as stable and balanced as possible. In addition, if the water temperature in the equipment is relatively low, some agents can be appropriately added, which can make up for the increase in the viscosity of the water flow and reduce the floating performance of the flocculate with air, so as to ensure the water quality.

Secondly, during the operation of air flotation machine equipment, the staff need to refer to the actual production conditions for appropriate adjustment, mainly according to the reaction pool flocculation, air flotation pool separation area scum and effluent water quality and other changes, timely adjust the amount of coagulant.

Then, to pay attention to the regular daily scum cleaning operations, can establish a suitable slag scraping system, but should pay attention to the daily work should be in accordance with the correct method to operate the air flotation machine, to ensure its efficient normal operation.
