Abstract

A scaling tool for replicating filtration characteristics of a large-scale filtration device, the scaling tool comprising a housing having a fluid inlet and a fluid outlet, and a filter receiving region in fluid communication with the fluid inlet and the fluid outlet and configured to contain a membrane comprising one or more pleats, the filter receiving region being defined by a rigid wall framework configured to hold the one or more pleats of the membrane and compress the pleats in an amount effective to replicate the filtration performance of the large-scale filtration device. Also disclosed is a methodology for configuring a filter receiving region in a scaling tool.

First claim

What is claimed is:

1. A cup-style scaling tool for replicating filtration characteristics of a large-scale filtration device, comprising:
a disc-shaped housing having a circular surface, wherein the circular surface includes a rectangular, wedge-shaped slot adapted to be a filter receiving region and cut-outs adjacent the wedge-shaped slot, the disc-shaped housing having a cup-shape and an annular groove capable of receiving a seal,
wherein the filter receiving region has a fluid outlet and extends axially from the circular surface, and comprises a rigid wall framework configured to hold and compress one or more pleats of a membrane and compress said one or more pleats in an amount effective to proportionally replicate the filtration performance of said large-scale filtration device; and
a wedge-shaped pleated membrane having one or more pleats and comprising ends capable of being placed in the cut-outs, and

a cover having one or more fluid inlets in fluid communication with said fluid outlet of said filter receiving region, said cover and said disc-shaped housing being sealed together.

2. The scaling tool of claim 1 , wherein said pleats of said pleated membrane are oriented in an M-pleat pattern.

3. The scaling tool of claim 1 , wherein said proportional replication is a 1:1 replication of throughput.
