    Abstract

    A large liquefaction tank used to prepare sand for laboratory testing required a 107-cm (42-in.) diameter filter. The filter was needed to separate the sand from water diffusers below, to facilitate a uniform upward flow of water, and to filter out undersired fines. The chosen design consisted of two geotextile fabrics sandwiched between a perforated plexiglass sheet and a steel grating. Selection of the geotextiles was based on the fabrics' porosities, permeabilities, and pore sizes. The system has been a success and has required no maintenance in over four years of usage.
