PEBBLES

Pebbles are composed of sub-angular, durable and dense grains of predominately siliceous material. These small roundish stones are either machined or have natural occurence. Moreover, sandstone pebbles are roundish or squarish in shape. Natural pebbles can be provided in various sizes as per requirement. It can be used directly as a filtration media or as a support system in the lower levels of the filter bed. Further, for supporting the media, the size needs to be calculated and the correct gradation is required. Water Filter Gravel or the Support Pebble is ideal for filtration as it provides high purity and consistent quality.


Extracted from a clean glacial deposit, our range of pebbles are used in various water treatment and filtration applications. ACURO's Pebble's physical properties make it adequate for various water filtration applications.
