How Walnut Shell Filter Media Works?

Walnut Shell Filter Media utilizes depth filtration, where contaminants are captured within the porous, irregular structure of the crushed shells. This increased surface area provides superior filtration performance compared to traditional filter media such as sand or gravel. It’s particularly effective in removing oil, grease, and other suspended contaminants from water and liquid streams.
