Information

Hazardous ingredients: CAS NO.

Active ingredient: Ca(ClO)2———— calcium hypochlorite

Preparation: chlorine gas into the lime milk calcium hypochlorite

2 Cl2 + 2 Ca(OH)2 = CaCl2 + Ca(ClO)2 +2 H2O

Calcium hypochlorite is made by the reaction of chlorine gas with calcium hydroxide (sluice lime). Because absolutely dry calcium hydroxide does not react with chlorine gas, chlorine can only be adsorbed by calcium hydroxide. For this reason, the industrial system uses sluiced lime containing less than 1% of free water to carry on chlorination, and the chlorine gas used also contains less than 0.06% of water. The free water in these raw materials is used to hydrolyze chlorine gas to produce acids (HClO, HCl), and the resulting acids are neutralized by slaked lime. Subsequently, depending on the water precipitated from the calcium hydroxide during the chlorination reaction, the chlorine continues to hydrolyze, and more calcium hydroxide is involved in the reaction process to form a series of compounds. Bleach is a complex of these compounds.

What are the applications of biological treatment in wastewater treatment engineering?
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.
