Walnut Shell Filter Media
Walnut shell filter media refers to a type of filtration material made from crushed walnut shells. The shells are typically crushed into granules of different sizes to create a filter media with a high surface area.
Walnut shell filter media is often used in water treatment processes, such as in sand filters or multimedia filters, to remove suspended solids, sediment, oil and organic matter from water.
Walnut shell filters are commonly used in various industries, including automotive, manufacturing, and oil and gas, for the removal of oil and other contaminants from liquids. Walnut shells have a high affinity for oil, allowing them to adsorb and retain oil molecules while allowing clean oil to pass through. This makes walnut shell filters useful for applications such as coolant filtration, hydraulic oil filtration, and oil wastewater treatment.
