Abstract
Tubular water filter for use in wells consists of concentric outer and inner perforated tubs produced by rolling textile webs impregnated with a curable binder and a filter material, pref., a block of porous material bonded to the webs or granules embedded in a binder. The particle size of the granules pref. increases from one tube to the other coaxially. The filter is more resistant to corrosion and more uniform than filters produced from metal by cutting or wound from metal wire.
