1. The purpose of treating scum is to improve the purification work better, and to make good use of the sucrose in the scum of the air flotation machine, and to prevent the contents of the scum from deteriorating. If we can't handle it well, the effect will be biased, and even side effects will appear. When we are doing phosphorus treatment, there is less scum, and it is not difficult to deal with, as long as a suction filter can be done.
2. Generally, the scum is returned to the mixed juice, and clarification is used for treatment. It is said that the calcium phosphate and flocculant in the scum can still function. You should know that after the scum is formed, there will be redissolution during the dilution process. And the greater the dilution of the scum, the more reconstitution it will contain, which we need to pay attention to. For example, the scum of the air flotation machine and different water are mixed and stirred for three minutes, and then filtered at a temperature of 95°C.
