Filtration system suitable for microfiltration, ultrafiltration or reverse osmosis

摘要

The invention relates to a filtration system. The filtration system comprises a filter unit having a housing enclosing a filter element. The unit has an inlet into the housing upstream of the filter element. The unit also has a retentate outlet from the housing upstream of the filter element, and a permeate outlet from the housing, downstream of the filter element. The permeate outlet is isolated from the retentate outlet and inlet by the filter element, while the retentate outlet is spaced from the inlet and in communication therewith. The system also includes a bundle made up of a plurality of releasably interconnected modular members at least one of which includes a valve, the bundle forming a flow control unit which controls fluid flow from the inlet to the permeate outlet. The invention also provides the filter unit of the system.
