【Summary】Bleach powder is a mixture of chlorine gas and hydrated lime, the effective component is Ca (ClO) 2, Ca(ClO)2 is easy to deteriorate when it encounters water and carbon dioxide in the air and loses or reduces its oxidation and sterilization ability. Therefore, the preservation of bleach to pay special attention to seal, in order to isolate air, at the same time to store in a dry and cool place. To measure the quality of bleaching powder, external view, bleaching powder is powdery, no agglomeration, smell a strong pungent smell, if bleaching powder agglomeration, the smell is light, the deterioration occurred.

Information

Bleach powder is a mixture of chlorine gas and hydrated lime, the effective component is Ca (ClO) 2,

Ca(ClO)2 is easy to deteriorate when it encounters water and carbon dioxide in the air and loses or reduces its oxidation and sterilization ability.

Therefore, the preservation of bleach to pay special attention to seal, in order to isolate air, at the same time to store in a dry and cool place.

To measure the quality of bleaching powder, external view, bleaching powder is powdery, no agglomeration, smell a strong pungent smell, if bleaching powder agglomeration, the smell is light, the deterioration occurred.

But some bleaching powder is powdery and has a strong taste, but it is not necessarily good.

So it is not enough to judge the quality of bleach by the senses alone.

The so-called "effective chlorine" refers to the percentage of the mass of chlorine released after the action of sufficient acid in the mass of bleaching powder.

For example, the effective chlorine of a bleaching powder is 70%, which means that every 100 parts of bleaching powder can release the equivalent of 70 parts of chlorine gas when completely interacting with the acid.

Obviously, the higher the effective chlorine content of bleaching powder, the better the quality of the bleaching powder and the greater the effectiveness.

The effective chlorine content of commercial bleaching powder is generally 60%-70%. In industry, the effective chlorine content of bleaching powder is generally determined by iodine quantification method. Although this method is accurate, it is complicated to operate and difficult to be accepted and used by individuals and pharmacies.

We can simply measure the content of effective chlorine in bleaching powder by blue ink determination method.

What are the applications of biological treatment in wastewater treatment engineering?
There are two types of biological treatment technologies that are most widely used in wastewater treatment projects: one is called activated sludge method, and the other is called biofilm method. The activated sludge process is a form of aerobic wastewater treatment performed by the biochemical metabolism of suspended biological groups.
