Nowadays, I believe that most companies and factories are very concerned about the issue of environmental protection, and all use recycled water treatment systems for sewage treatment. In the process of circulating water treatment, such as (proteins, polysaccharides, including other circulating water agents 'aqueous system containing active ingredients'), continuous circulating water system operation, a large number of actinomycetes and filamentous bacteria in the water, plus Stirring and stirring the incoming air, the foam naturally emerges, the foam is mostly yellow-brown and is not easy to handle. The circulating water treatment foaming will directly affect the normal operation of the water treatment system, so most of the plants will use the defoamer for circulating water treatment defoamer.
De-foaming with de-foaming agent for circulating water treatment can be said to be a low-cost and simple solution. But do you really know how to use the defoamer for circulating water treatment? The following are some of the methods and precautions used by Xiaobian for everyone's work on circulating water treatment defoamers. Let's take a look.
It is recommended to use 1-3 times diluted with water or solvent (but also foaming liquid) before use;
Dropping method, the antifoaming agent is dropped in a place with a lot of bubbles, so that the antifoaming agent can be utilized to the maximum extent.
Concentratively adding, adding or spraying in the place where the foam concentrates, or adding directly in the well of the sewage with good fluidity. It is recommended to use 30-300PPM.
In the use of recycled water treatment defoamer, the amount does not need too much, only 0.05% ~ 0.1%, adding too much is a waste. In the course of dilution, it is not possible to dilute the excess. When the solid content reaches 5% or more, the defoaming effect of the defoamer for circulating water treatment will be significantly reduced, and more defoamers will need to be added to achieve the defoaming effect. This is not worth the loss. It! If the dilution is to be used immediately, it must be diluted and stored for a long time. Remember to add stabilizers.
All right. Today Xiao Bian wrote it here, I hope to be helpful to everyone. Of course, if everyone has a better solution for the solution of circulating water treatment defoamer, you can also leave a message or consult the circulating water treatment defoamer. Go to the column to see!
