Berkey - composition of the Black Berkey filter

The Black Berkey filter is a type of filter used in water purification systems manufactured by the Berkey company. Here's the typical composition of the Black Berkey filter:

1. Activated carbon: Activated carbon is used to remove organic contaminants, chemicals, herbicides, pesticides and solvents from water.

2. Ceramic purification media: This media helps remove particles and bacteria from water. It uses extremely fine pores to trap contaminants and provide additional filtration.

3. Specialized media for heavy metal reduction: Black Berkey filters also contain a specialized media designed to reduce the presence of heavy metals such as lead, mercury, cadmium and other metallic contaminants.

A "media" in the context of water or air filtration is a material used to capture, retain or remove contaminants present in the flow of air or water passing through a filtration system. Media are designed to have specific properties that enable them to perform different filtration functions.
