APPLICATIONS, PART OF MULTIMEDIA AND SAND FILTRATION SYSTEMS

IWE water filter sand is composed of sub-angular, hard, durable, and dense grains of predominately siliceous material. Extracted from a clean glacial sand deposit, IWE Sand and Gravel ’s physical properties make it among the finest available in the world for filtration applications. Our water filter sand is washed, kiln dried, and screened to meet EXACTING specifications with strict adherence to quality control.

We also specialises in custom grades of sand and gravel to meet your stringent specifications.
Sand is characterized by the diameter of the individual sand grains (eg 0.15-.35 mm) and the effective size of the composite sand, the ES or d10. d10 is defined as the sieve size in mm that permits passage of 10% by weight of the sand. The uniformity coefficient (UC) of a sand is defined as d60/d10.

Sand needs to be of a fine grade ( 0.15-.35 mm is recommended), uniform (the UC should always be less than 3 and preferably less than 2), and be washed free of loam, clay, and organic matter. Fine particles will quickly clog the filters and frequent cleaning will be required. A sand that is not uniform will also settle in volume, reducing the porosity and slowing the passage of water. Sand manufacturers should be able to supply or blend sand to these specifications.
