Zusammenfassung: | A filtration apparatus includes a tubular casing having a longitudinal axis and first and second casing ends. A plurality of partition plates are positioned in the casing and sealed thereto to thereby define an intake collection chamber between a first of the partition plates and the first casing end, a discharge collection chamber between a second of the partition plates and the second casing end, and a reject collection chamber opposite the second partition plate from the second casing end. A plurality of elongated filtration membrane stacks are positioned side-by-side in the casing generally parallel to the longitudinal axis. Each filtration membrane stack includes an intake end which is fluidly connected to the intake collection chamber, a discharge end which is fluidly connected to the reject collection chamber, and a permeate channel which extends between the first and second ends and is fluidly connected to the discharge collection chamber. The filtration apparatus further includes an intake pipe having a first end that is fluidly connected to the intake collection chamber and a second end that is fluidly connected to a first connector which is located proximate the second casing end; a discharge pipe having a first end that is fluidly connected to the discharge collection chamber and a second end that is fluidly connected to a second connector which is located proximate the first connector; and a reject pipe having a first end that is fluidly connected to the reject collection chamber and a second end that is fluidly connected to a third connector which is located proximate the first and second connectors. In use, a fluid to be filtered is communicated to the intake collection chamber through the intake pipe and is separated by the filtration membrane stacks into a permeate which is discharged from the discharge collection chamber through the discharge pipe and a reject fluid which is discharged from the reject collection chamber through the reject pipe. |
