MORE FILTRATION, LESS ENERGY
The SANI Membranes Free Flow Plate™ technology is also well suited for nanofiltration, reverse osmosis and even forward osmosis applications. The key benefits of the Free Flow Plate™ technology in NF and RO application is the open feed channel designs ability to handle difficult feeds without pre-filtration. A concept for Free Flow Plate™ technology forward osmosis modules has also developed. The business focus is however on microfiltration and ultrafiltration applications for the time being.
The Free Flow Plate™ Technology can also be used in nanofiltration applications. The current products restrict the maximum pressure to 4 bar. This means only low pressure nanofiltration applications can be handled by the current products.
The Free Flow Plate™ Technology can also be used in Reverse Osmosis applications. The current products restrict the maximum pressure to 4 bar. This means only low pressure Reverse Osmosis applications can be handled by the current products.
The SANI Membrane Free Flow Plate™ technology was originally designed with a sanitary retentate side and a sanitary permeate side. In fact, the permeate side can be flush cleaned. This feature makes it possible to create true cross flow, where a turbulent flow is established on the outside (the feed side) of the membrane as well as on the back-side (the draw side) of the membrane. This make the Free Flow Plate™ technology uniquely efficient as a base technology for forward osmosis.
Forward osmosis is still only used in smaller industrial systems as industrial solution to draw-recovery is still not obvious.
