Nutshell Filter Media in Water Treatment Suppliers in China

Introduction

Nutshell filter media is new generation of light filter material in water treatment instead of silica sand filtering medium. Because walnut shell filter media has the advantages of high hardness, ideal specific gravity, porosity and versatility, and after special physicochemical treatment (for example, removing off its color agents, fat, grease and negative ion), making 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. Walnut shell filter media is normally used 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 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

Walnut Shell Filter Media Advantages
