What is Activated Clay?

- Nov 17, 2017 -

Activated clay is clay, usually of bentonite origin, which has been treated to improve its ability to adsorb. The clay is processed with acid, upping the adsorption properties of the clay considerably. Once it has been treated, activated clay can also be reactivated as it is used, allowing people to reuse the clay rather than having to continually replace it. There are a number of uses for this product, and it can be found directly through manufacturers and at locations like home supply stores and stores which stock auto repair supplies.

When activated clay is spread across a surface, it readily adsorbs oils and other materials present on the surface. One use for this product is in auto shops and similar repair facilities where oil often ends up on the ground; activated clay can be used to soak it up so that it can be safely removed. This product is also used in environmental cleanup of oil spills and other incidents, and in other settings where oils may accumulate, as for example in slaughterhouses where fat and grease can build up.

This product can be reactivated by heating it to get it to release the substances it has adsorbed, allowing people to reuse it. Since activated clay is sometimes used with materials which are toxic or dangerous, it is important to make sure that it is reactivated by someone with experience; one wants to avoid releasing the materials so carefully cleaned up with the assistance of the clay. People can also discard this product by securely bagging it and depositing it in waste containers which are designed to accommodate the types of materials picked up by the clay.

Companies may also refer to this product as “bleaching clay,” referencing the fact that it can bleach out pigments. Bleaching clay is used in materials processing in a variety of industries to pull out pigments, as seen for example in paper processing. It can also be used to purify and refine oils by pulling out impurities and pigments and leaving the clean oil behind.

Keyway Industrial Limited company reminds,when not in use, activated clay should be stored in a cool, dry place. If the clay is exposed to moisture it can pick it up, and in warm environments, the clay will release fluids, and it can become messy. Some people store it in sealed tubs to keep moisture out of the activated clay while it is not in use.
