Black Walnut Shell Media

BLACK WALNUT SHELL MEDIA USES
Black walnut shell media is used often by oil industry as lost circulation material and as a nutshell filter media for cleaning produced water. It's a new generation of light filtering material instead of silica sand filtering medium. Because black walnut shell filter media has the advantages of high hardness, heavy specific gravity, porosity and versatility, and after special physicochemical treatment (for example, removing off its color agents, fat, grease and negative ion), making black walnut shells has excellent oil removal, solid particles removal and easy backwashing performance in oily water treatment, industrial waste water treatment and civil water treatment. Black walnut shell filter media is normally used for nutshell filters into water treatment equipment in petroleum company or refinery enterprise to improve water quality and reduce water treatment costs greatly. Walnut shell filter media adopts good quality black walnut shells as raw materials, after producing processes of breaking up, winnowing, polishing, steam & wash, drug treatment and twice screening.
Suggested mesh sizes are 10/12, 12/16, 16/20, 20/35
