Abstract
A filtration apparatus has a horizontally oriented permeate conduit supported on the floor of a tank. A module of filtering membranes may be placed on or over the permeate conduit and communicate with the permeate conduit. The module may be of a variety of configurations including one with vertically oriented hollow fibers. A permeate collector may be connected to the permeate conduit by a second permeate conduit. The connection may be made near the top of the module and may be through an isolation valve. The apparatus is suitable, among other things, for installation in a sand filter tank. Permeation may be by gravity flow. This abstract is not to be used to construe the claims.
