Take the tube
15 Jan 2000
A new tubular membrane filtration system, which applies nanofiltration technology to the recovery of cleaning chemicals, has been launched by PCI Membrane Systems.
Capable of operating at temperatures of up to 60 C and handling a pH range between 1 and 14, the Reco-CIP system can typically recover up to 95 per cent of an active chemical solution.
Modular in design, the Reco-CIP is said to be straightforward to clean. Continuous or batch process operation is possible and the nanofiltration units can be run for up to 22 hours prior to cleaning. Organic compounds in the spent cleaning solution are retained by the Reco-CIP membrane, allowing the permeate to be re-used.
Suspended solids, oil and grease as well as up to 75 per cent of Kjeldhal nitrogen are all rejected by the Reco-CIP, which can operate at pressures between 14 and 28 bar.
