PRODUCT 

Walnut Shell can be used to remove suspended solids 
and organic material from produced water, surface water 
and river, lake and well water. Walnut Shell Grit treats and 
removes suspended solids, oily residues, ash and metallic 
hydroxides from industrial liquids in power generation, 
metal working, and municipal chemical petroleum and 
petrochemical applications. 

OTHER USES 

Walnut Shell Grit prevents lost circulation on oil well 
drilling. Provides a non-skid enhancer in abrasive paints 
around swimming pools, walkways, dock boards and other 
areas where a rough surface is required. Serves as a filler 
prior to burnout – a porosity enhancer for grinding wheels 
and ceramics.  Preserves gel-coat when removing paint 
from fiberglass boats. Wide range of surface patterns can 
be achieved with 7 grades of Walnut Shell Grit (6/12 to 
60/100) available.
