Filtering Materials

Definitions Anthracite : A granular hard coal used as a filtration medium in multi-media filters. Backwash : The procedure used to flush deposited solids out of the granular filter at the end of the filter run. This normally involves feeding clean water in the base of the granular bed and washing it in an upward direction. Design Engineer : The Engineering Company responsible for specifying the design requirements for ROS on the drawing sheet, in accordance with the requirements of this specification.

Page 3 of 18



Filter Medium: The term filter "media" is in common use to describe granular filtering materials. Grammatically, it is plural and should apply to the bulk material to be installed in several filters. (A single filter has a filter medium). To avoid ambiguity the term "filtering material" used in the American Water Works Association (AWWA B100) specification is preferred. Packing layer : A granular material, coarser than the working filtering material, which is not intended to capture suspended solids and neither is it intended to move or be fluidized during filter backwash. Polyelectrolyte : An organic chemical compound with many repeated structural units produced by uniting many primary units, called monomers. It is added to the water to agglomerate particles into larger groupings called flocs, which then settle by gravity. Pretreatment : All the unit operations upstream of the reverse osmosis (RO) system that have purpose to eliminate or minimize the fouling potential of the RO feed water. Saudi Aramco Inspector : The person or company authorized by the Saudi Aramco Inspection Department to inspect ROS to the requirements of this specification. Silt Density Index (SDI) : A measurement of the rate of plugging of a 0.45 micron Millipore filter at 207 kPa (30 psig) applied pressure.
