Air flotation machine is a common wastewater treatment equipment, its main principle is to use bubbles to float the suspended substances in the water, so as to achieve the purpose of purifying water quality. In an air flotation machine, adding a certain amount of flocculant can accelerate the settling speed of suspended substances and increase the lifting force of the bubbles, thus increasing the contact area between the bubbles and the suspended substances and promoting the floating of the suspended substances. However, in practice, there are times when the floc does not float after the flocculant has been added. Why is this? Firstly, we need to understand how flocculants work. Flocculants are high molecular organic compounds that are electrically charged and can react chemically with suspended substances in the water to form larger flocs, thus causing the suspended substances to precipitate or float. However, if not used properly, the flocculant can be added in excess or too little, thus affecting the normal operation of the air flotation machine. Secondly, the flotation effect of an air floatation machine is related to the size and number of bubbles and the lift force. The smaller the bubbles, the greater the number, the greater the lift, the greater the contact area between the bubbles and the suspended material, and the better the flotation effect. However, adding too much flocculant will reduce the contact area between the bubbles and the suspended material, and the lift force of the bubbles will be reduced, resulting in flocs not floating easily. In addition, if the flocs are denser, this will also affect their floatation rate. In addition, the operating conditions of the air floatation machine can also affect the floating effect of the floc. For example, the speed of the water flow in the flotation machine, the depth of the water and the way in which the bubbles are generated can all have an effect on the flocs floating. Improper operating conditions can also lead to flocs not floating easily.
Finally, it should be noted that different types of flocculants have different ranges of application. If used incorrectly, they can also affect the normal operation of the air flotation machine. Therefore, when using flocculants, you need to choose the appropriate type and addition amount according to the actual situation and adjust it with the operating conditions in order to achieve the best flotation effect. In conclusion, there may be various reasons why flocs do not float in air flotation machines after flocculants are added, and the influencing factors need to be considered and adjusted appropriately to ensure the normal operation of the air flotation machine and the purification of water quality.
