Ultrafiltration

The ultrafiltration process is a physical process for cleaning and recycling of the wiping solution used in the intaglio printing presses.
This is a wastewater free process.

The core elements for this tailor-made application, are our ceramic membranes. These membranes not only enable very high percentages of wiping solution recovery but avoid the costs for usage, storage and disposal of many chemicals needed for other processes (chemical filtration).

Another great attribute of our special designed ceramic membranes is their long lifetime (approximately 5 to 7 years).

The spent wiping solution is separated into a recovered solution (permeate) and in a side stream of sludge with high and controllable solid concentration (intaglio ink waste).
The permeate collected in a storage tank during the process, can be reused for wiping without any further treatment.

The system performs automatically a cleaning process of the membranes, after the conclusion of a selected work batch size.

Thanks to the high recovery rates and the low use of chemicals, the final amount of waste is not only extremely reduced but – to fulfill further customer requirements – can be further treated to a dry waste (see our exclusive Spray Dryer System).
