    Share with you the knowledge of diatomite decolorization

    Diatomaceous earth is actually formed by the accumulation of layers of remains of ancient diatom plants and other single-celled organisms. Generally, diatomaceous earth tends to be white, such as white, gray, gray, etc., because its density is generally only 1.9 to 2.3 per cubic meter, so its int...
