pumice were found to be 85-90% and 98-99%, respectively. Furthermore, the head loss for sand and pumice were found to be 460 mm and 215 mm, respectively. The results obtained have shown that pumice has a high potential for use as a ˜lter bed material. * Burhanettin Farizoglu, Bulent Keskinler. Published in Filtration and Separation, April 2003

Pumice Perlite. 7.2.4. Pumice. Pumice is a form of natural volcanic rock where a very low viscosity lava shot to the Earth's surface full of gas. The gas expanded rapidly at the surface before the molten rock could cool. The rock thus became a very lightweight . This is dug up, crushed and sorted to various sizes.
