Armfield - Miniature-Scale Research & Development Technology - FT18 Reverse Osmosis/Ultrafiltration Unit

The Armfield Reverse Osmosis/Ultrafiltration (RO/UF) unit is the smallest known industrial membrane system of its type in the world. It is designed specifically for laboratory-scale testing of both reverse osmosis and ultrafiltration techniques.

The FT18 is a fully self-contained in a mobile cabinet. Comprehensive instrumentation is provided with digital meters displaying temperatures and system pressure. In addition to the membrane module, the cabinet also houses feed and permeate tanks, a plate heat exchanger and positive displacement pumps. Connection to cooling water and a suitable electrical supply is all that is required for normal operation.

All parts in contact with the process fluid are constructed from hygienic design materials such as stainless steel, PTFE and silicone rubber.

The RO/UF unit has an efficient Clean-In-Place (CIP) facility and is easily dismantled for servicingor maintenance. It uses a PCI MICRO 240 membrane mdoule, which accomodates all PCI membrane types. The unit is supplied with a pack of both R.O. membranes (AFC99) and U.F. membranes (ES625).

Membranes can be installed or removed rapidly for use in either process.

The filtration membranes differ only in length and quantity from those installed in the full-scale plant. Using small quanitities of process fluid, operating paramters can be established and then optimised to effect a confident transition to full-scale.
