bleach clay extraction process

Manufacturing Process Bleach (Sodium Hypochlorite)

This process is called electrolysis. Sodium chloride, commonly known as table salt, comes from either mines or underground wells. The salt dissolves in hot water to form a salt solution which would be tested for impurities before the electrolysis process ("How Bleach is Made", 2007).

Extraction Methods.edited.docx Extraction Methods 1

This process involves mixing the oil with the required amount of bleaching clay, and then the mixture is slightly heated. After the bleaching process, the oil is filtered to remove the clay and other substances.

The oil produced was refined through degumming, neutralization and bleaching process using local adsorbent (activated clay).

The bleaching process of edible oil_edible oil bleaching

In the bleaching process of edible oil, it is exactly using white clay or active carbon to absorb pigments in crude edible oil. So edible oil bleaching process is a physical process, which can also remove part of residual phosphatides, metals, soaps and oxidation products. And then, the waste white clay is removed by leaf-filter machine.
