Defoamer in the water treatment industry amazing defoaming effect
In the production process of many different processes will discharge a large amount of wastewater, wastewater needs to be treated to meet the standards before discharge, wastewater impurities, most of them will produce a large amount of foam, too much foam will bring many adverse effects, so in the process of water treatment most need to add defoamer to defoam in order to discharge, so why is defoamer recommended for the water treatment industry?
In the water treatment industry we first need to understand the causes of its foaming:
1、The production equipment contains a certain amount of foam, the high temperature of the inlet water foam particles will be more, the production process of water circulation will also lead to a large number of foam appear.
2, The water contains a large number of impurities, impurities and gases and other systems mixed together in the water flow machinery and other continuous stirring action to produce a large number of bubbles.
3、The change of PH value in the water treatment will cause the active mud not to adapt, thus generating foam.
4、Insufficient dissolved oxygen in the water treatment, the system is low load operation, easy to produce back nitrification foam.
Why are defoamers recommended for the water treatment industry?
1, In the water treatment industry, defoamer has good chemical stability, not easy to produce adverse chemical reactions with other impurities in the wastewater, can continue to stabilize the defoaming.
2, Used in the water treatment industry defoamer viscosity is low, in the water phase system has good dispersion, can quickly eliminate the foam.
3, The amount of defoamer is small but has a highly efficient defoaming ability, easy to use, simple operation, can be added directly to the foaming system.
In the process of adding defoamer in the water treatment as far as possible in accordance with the formal methods of adding the use of defoaming, in adding defoamer need to pay attention to the following points can reduce the amount of defoamer, there will also be a better defoaming effect.
1, When adding defoamer to stir evenly dispersed, so that the defoamer to play a continuous defoaming ability
2, Defoamer in the process of adding recommended the use of metering pump continuous drip, easier to control the amount added.
3, Pay attention to the temperature when adding defoamer, for example, some defoamers to be added at low temperatures with better results.
4, The specific amount of defoamer needs to be constantly tested, need to be determined according to the defoaming situation after the field test.
