Many friends who use air flotation have such troubles, because they do not know how to deal with the scum of air flotation. I think first of all, everyone should know what scum is, and what harm does scum do to air flotation, and then come to find a solution, and this is our theme. Let Wanchuan Environmental Equipment give us a brief explanation. .
In fact, the purpose of treating the scum is to better improve the purification work, and to make good use of the sucrose in the scum, and to prevent the content 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 carrying out phosphorus treatment, the scum that we scold him is relatively small, and it is also difficult to deal with, as long as a suction filter can handle it.
Generally abroad, the scum will be refluxed into the mixed juice, and it is treated by clarification. I heard that it is because the calcium phosphate and flocculant in the scum can also function. You must know that after the scum is formed, there will be redissolving in the process of dilution. And the greater the dilution of the scum, the more reconstituted it will contain, which we need to pay attention to. For example, the scum and different water are mixed and stirred for three minutes, and then filtered at a temperature of 95°C.
