Abstract
A unit for producing pyrogen controlled water on a small to medium factory scale comprises a number of charged ultrafiltration units arranged in parallel. Orifice plates are used to restrict and control the flow of deionized water to each filter . The filter units are mounted on a frame with a wheeled chassis which may be pushed or moved by a forklift truck to a site where pyrogen controlled water is required. The unit has an inlet line for connection to a supply of deionized water and an outlet line for connection to a user of pyrogen controlled water. The unit may be purged with nitrogen from a supply . Sampling ports in a common supply inlet and a common outlet ensure that the filtration efficiency can be closely monitored. The flow of water is monitored by a flowmeter and pressure sensors upstream of each filter facilitate a high level of control.
