Product Description

what is diatomaceous earth?

Diatomite is a friable light-colored sedimentary rock?that is mainly composed of the siliceous skeletal remains of diatoms. It is a very porous rock with a fine particle size and a low specific gravity. These properties make it useful as a filter media, an absorbent, and as a lightweight filler for rubber, paint, and plastics.

Main Size of Diatomite as follows:

Granular:0.2-0.8mm,0.6-1.6mm,1-3mm,3-6mm,5-10mm,8-11mm,15-30mm,

Powder:60-100mesh,300mesh

Characteristic:

Small particle size
High porosity
High surface area
Relatively inert siliceous composition
Low specific gravity

Usage

Agriculture

Natural freshwater diatomaceous earth is used in agriculture for grain storage as an anticaking agent, as well as an insecticide.It is approved by the Food and Drug Administration as a feed additive to prevent caking.

Hydroponics
Freshwater diatomite can be used as a growing medium in hydroponic gardens.
It is also used as a growing medium in potted plants, particularly as bonsai soil. Bonsai enthusiasts use it as a soil additive, or pot a bonsai tree in 100% diatomaceous earth. Like perlite, vermiculite, and expanded clay, it retains water and nutrients, while draining fast and freely, allowing high oxygen circulation within the growing medium.

Catalysts

Diatomaceous earth also finds some use as a support for catalysts, generally serving to maximize a catalyst's surface area and activity. For example, nickel, referred to as Ni–Kieselguhr, can be supported on the material to improve its activity as a hydrogenation catalyst

Filtration

One form of diatomaceous earth is used as a filter medium, especially for swimming pools. It has a high porosity because it is composed of microscopically small, hollow particles. Diatomaceous earth (sometimes referred to by trademarked brand names such as Celite) is used in chemistry as a filtration aid, to filter very fine particles that would otherwise pass through or clog filter paper. It is also used to filter water, particularly in the drinking water treatment process and in fish tanks, and other liquids, such as beer and wine. It can also filter syrups, sugar, and honey without removing or altering their color, taste, or nutritional properties.
