With Ultrastil Christ 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 for the retention. This guarantees fulfilling the recommendations of cGMP, GAMP and ISPE.
