Do defoamers have any effect on microorganisms? How big is the impact? This is a question often asked by friends in the wastewater treatment industry and fermentation products industry. So today, let's learn about whether defoamer has any effect on microorganisms.
The effect of defoamer on microorganisms is minimal. There are four common types of Papermaking defoamer: natural oils, fatty acids and esters, polyethers, and silicones. Our common fermentation industry often uses defoamers of natural oils and polyethers. These Anti Foaming Agent are basically friendly to fermenting microorganisms and will not have any effect.
But this is also relative. The principle of using defoamer is to use a small amount and many times. When too much Natural Anti Foaming Agent is added at one time, it will have a certain impact on the production system.
That is because:
1. Excessive addition of Antifoam Food Grade will increase the liquid film resistance, thereby affecting the dissolution of oxygen and the transfer of other substances.
2. A large number of bubbles burst, resulting in a rapid reduction of the gas-liquid contact area, resulting in a decrease in KLA, and a decrease in oxygen supply under the condition of constant oxygen consumption.
Therefore, the defoamer will not affect the microbial cells, but excessive addition will affect the transmission of oxygen.
The growth of foam is regular, and different foaming systems have different rules. In most cases, defoamer is used to solve the problem of excessive foam.
However, in the middle and late stages, the growth of the foam may be caused by the self-melting of the bacteria due to insufficient nutrition. At this time, in addition to the use of defoaming agents, supplements should be used to supplement nutrients, maintain the growth of microorganisms and inhibit foam, and also increase oxygen consumption.
Although the defoamer will not have much impact on the microbial system, everything needs to be analyzed in detail. When it is necessary to use the defoamer, you should consult the defoamer manufacturer, listen to the answers of professionals in detail, and carry out Samples, make sure there is no problem before you can use it with confidence.
