Paper production will produce a lot of waste water. It is a common phenomenon that a lot of bubbles appear in the process of waste water treatment. Foams will affect the quality of paper making paper. Many bubbles in the wastewater treatment stage will increase the cost of water treatment. It can be eliminated by adding paper. Foaming agent solves the problem of foaming. A well-targeted papermaking defoaming agent not only has good defoaming performance, but is also very convenient to use. This article analyzes the reasons for the foaming of papermaking wastewater and gives solutions for defoaming.

Reasons for the foaming of papermaking wastewater
1. The wastewater contains surfactants
Due to the use of a large number of additives in the papermaking process, the surface tension of the system is changed, and foam is easily generated. Foam is a dispersed system in which gas is separated by liquid, and gas phase is the dispersed phase. The liquid phase is the dispersion medium. The papermaking wastewater contains one or more surfactants with foaming and foam stabilizing effects, which can promote the formation and stability of bubbles.
2. The papermaking wastewater treatment process produces foam
For example, biological foam is caused by abnormal production of filamentous bacteria. Surfactants play a foaming and stabilizing role, and filamentous bacteria further enhance the stability of biofoam. Due to the slender structure of filamentous bacteria, it is almost completely inelastic when it collides, and it is easy to adhere to bubbles. Therefore, the proliferation of filamentous bacteria provides a three-dimensional framework for the development of biological foam to space, which prevents the merger of bubbles and promotes the formation of biological foam.

Papermaking wastewater defoaming plan
Papermaking wastewater treatment is due to production raw materials, water treatment technology and other reasons. It is difficult to avoid a large amount of foam in papermaking wastewater. A large amount of foam will not only affect the papermaking wastewater treatment process, but also increase the difficulty and cost of wastewater treatment. The foam problem can be solved by adding a defoamer.
Nanhui defoamer manufacturers are prone to a large amount of foam in the treatment of papermaking wastewater. The papermaking defoamer developed and designed in a targeted manner not only has a fast defoaming speed, but also has strong foam suppression.

Nanhui Paper Defoaming has the following advantages:
1. Stable defoaming performance, resistant to high temperature, acid and alkali and other environments, and can continue to defoam;
2. It is chemically inert, will not react with wastewater and will not affect the wastewater treatment process;
3. For the formula, provide customized services, and customize the defoaming formula according to customer needs.
Nanhui is a manufacturer with years of application experience. It has far more defoaming technology than other antifoaming agents in the market. From the above cases, we prove the strength of our Nanhui defoamer. We have a group of excellent defoaming engineers, and an independent laboratory that facilitates defoaming experiments with foams that are difficult for customers to solve.
