MORE FILTRATION, LESS ENERGY
The SANI Membranes Hollow Plate™ technology is also well suited for nanofiltration, reverse osmosis and even forward osmosis applications. The key benefits of the Hollow Plate™ technology in NF and RO application is the open feed channel designs ability to handle difficult feeds without pre-filtration. A concept for Hollow Plate™ technology forward osmosis modules has also developed. The business focus is however on microfiltration and ultrafiltration applications for the time being.
The Hollow 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.
The Hollow 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.
The SANI Membrane Hollow 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 Hollow Plate™ technology uniquely efficient as a base technology for forward osmosis. The present webpage was made public in October 2016 to secure freedom to operate using Hollow Plate™ technology for forward osmosis.
Forward osmosis is still only used in smaller industrial systems as industrial solution to draw-recovery is still not obvious.
