Walnut Shell Filters are down flow, deep bed, nut shell media filters designed for oily water filtration.
As the liquid passes through the walnut shell filter's media bed, oil and solids are efficiently retained in the bed and can easily be backwashed out of the media.
One huge advantage of walnut shell media is its superior filtration of wastewater.
Walnut Shell Filters will typically remove 95% of solids at 5 micron, and 90% of suspended oil.
Walnut shells have a natural affinity for oil, causing it to bond to the surface of the media. Unlike in sand filters, whose captured oil films over the surface, captured oil remains as droplets. These absorbed droplets will then contact smaller droplets, which coalesce onto the larger droplets and increase the removal rate of small particles over time.
Walnut shells have an oil absorption capacity that is 2-3 times that of sand.
