Abstract:
A cross-flow multi-filter module assembly, comprising two spider fittings each in opposed facing relationship to one another, and including a central hub body having an interior volume, and having arms joined in fluid flow communication with the hub body interior volume, with each of the arms extending generally horizontally radially outwardly to a radially outer flanged terminus, and a right angle pipe fitting being coupled to each of the arms of the spider fitting, the right angle pipe fitting being flanged at respective ends thereof, with one of the flanged ends of said right angle pipe fitting being abuttingly engaged with the radially outer flanged terminus of an arm of the spider fitting so that the right angle pipe fitting extends generally horizontally radially outwardly from the said one of the flanged ends thereof and then generally vertically to the other of the flanged ends thereof, with said other of the flanged ends of the right angle pipe fitting being coupleable to an end portion of a filter module, and with respective filter modules arranged parallel to one another, each said filter module (1) including at least one permeate discharge for discharging permeate produced by filtration in said filter module, and (2) extending between said other of the flanged ends of a first right angle pipe fitting at a first end of the filter module said other of the flanged ends of a second right angle pipe fitting at a second end of the filter module wherein a lower end of each said hub body includes means for introducing or discharging a medium to or from the respective said interior volume, and wherein a distance from the interior volume of one of said spider fittings through the filter module to the interior volume of the other of said spider fittings is the same for each of the filter modules in said assembly, and wherein at least one of said spider fittings comprises an upper segment joined by a flange to the hub body, which upper segment includes a central bore opening which communicates with the interior volume of the hub body, and wherein the upper segment terminates at its upper end in a flange.
