Quartz sand

Silica Sand 1.very high purity, SiO2 99.9% min 2.very low Fe ion, Na+ ion, Cl- ion. MAIN APPLICATIONS

  Drinking water        Industry waste water         Residential water 

APPEARANCE

Quartz sand: Light and white granule

Gravel:          Rough granule

Pebble:         Slick spherical shape

ADVANTAGE

.

1. Graded specifically for water filtration plants

2. Desirable chemical properties, color, and wide range of precision sizing

3. The spherical shape of uncrushed gravel promotes good flow and even distribution
