Ready to connect Membrane Filtration System “Ultrastil“/ Economical Raw Water Filtration

Water in its original quality may not always be directly treated to fulfill the requirements of the pharmaceutical, cosmetic or chemical industry for production or rinsing purposes. With Ultrastil, Christ now introduces a ready to connect membrane filtration plant for the removal of suspended solids from aqueous solutions. It is suitable for the filtration of raw water capacities up to 8 m3/h. The system may be installed upstream of reverse osmosis and electrodeionization units and ensures a SDI (silt density index) of < 3.

The module works based on the absolute filtration method (dead end) which ensures economical operation of the plant. Ultrastil combines the following process steps: raw water feed, rinsing, ultrafiltration, pure water storage, cleaning and disinfection as well as a Simatic S 7 control cabinet for the control and monitoring of all fully automated processes. The ultrafiltration membranes installed have a pore diameter of approximately 0.01 µm ensuring a cut-off of 100 kD (kilo Dalton) for the retention. This guarantees fulfilling the recommendations of cGMP, GAMP and ISPE.

The filtration module made of PE/PES is pre-qualified ex works; on request, Installation Qualification and Operational Qualification may also be executed. Assembly work during the commissioning of the plant on site is not necessary since the membrane filtration system is supplied ready to connect or as a component of the compact high-purity water treatment plant Osmotron.
