The method of treating scum with air flotation machine

Generally, foreign countries will return the scum in the flotation machine to the mixed juice for treatment with clarified Limewater. It is said that calcium phosphate and flocculant in the scum can also act. You should know that after the formation of scum, there will be re dissolution during the dilution process. Moreover, the greater the dilution of the scum, the more re dissolved it will contain, which is something we need to pay attention to.
Purpose of handling scum
The purpose of treating scum is to better improve the purification work, and to make good use of the sucrose in the air flotation machine scum, and to prevent the content inside the scum from deteriorating. If we cannot handle it well, there will be deviations in the results and even side effects. When we are dealing with phosphorus, there is relatively little scum, and it is not difficult to handle it. Only one suction filter can handle it.
Method of handling scum
Usually, the scum is refluxed into the mixed juice and treated with clarification. It is said that the calcium phosphate and flocculant in the scum can also act. You should know that after the formation of scum, there will be re dissolution during the dilution process. Moreover, the greater the dilution of the scum, the more re dissolved it will contain, which is something we need to pay attention to. For example, dissolve and stir the floating slag of an air flotation machine with different types of water for three minutes, and then filter it at a temperature of 95 ℃.
