Modular Cross Flow Filtration
MINIATURE-SCALE R&D TECHNOLOGY
FT18MkII Modular Cross Flow Filtration
The Armfield FT18-MkII is a small pilot-scale cross-flow filtration system designed to operate with a range of membrane module configurations. It can operate with as little as 5-10 litres of material but still give data that is useful for process scale-up. It can be used over the full range of cross-flow filtration applications from microfiltration through to reverse osmosis. It is the perfect tool to use, following on from flat sheet membrane trials with the FT17, for further process development and scale-up.
Features
• Dual operation, RO/UF
• Uses proprietary membranes available from PCI
• Clean-in-place (CIP) facility
• Mobile and self-contained operation
• Computer linked for data logging and analysis
Benefits
> Rapid changeover from R0 to UF and back
> Easily cleaned and maintained

Vessel (FT18-20)
30-litre 316 stainless steel retentate vessel for recirculated product, complete with sensor to protect against dry running. Mass balance option for permeate flow rate measurement.
Electronic Flow Meter (FT18-44)
- Electronic flow meter that measures the recirculation (retentate) flow rate
- Must be ordered with FT18-MkII base unit
Backpulsing/Backflushing (FT18-50)
- This module enables filtration pressure to be reversed for a period of time during processing in order to reduce fouling and thus enable extended operation between cleaning cycles
- This module is compatible with the Ceramic (FT18-5) and Hollow Fibre (FT18-7) filter modules only
- Must be ordered with FT18-MkII base unit
System Control
- As standard the system is controlled by a PC (not supplied) with a USB interface
- An optional touchscreen system (FT18-60) can be used in place of a PC (not supplied)
