MORE FILTRATION, LESS ENERGY
NF, RO and FO
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 10 bar. This means only low pressure nanofiltration applications can be handled by the current products.
Reverse Osmosis (RO)
The Free Flow Plate™ Technology can also be used in Reverse Osmosis applications. The current products restrict the maximum pressure to 10 bar. This means only low pressure Reverse Osmosis applications can be handled by the current products.
Forward Osmosis (FO)
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.
