Organic Solvent Nanofiltration Unit
The principle of the OSN Unit is the cross flow over the membrane, dividing the inlet flow into solute enriched solvent upstream (concentrate) and purified solvent downstream (permeate).
In addition to the membrane stage the BORSIG Organic Solvent Nanofiltration Unit usually consists of a feed pump and a circulation pump. The feed pump pressurises the process fluid to the filtration pressure and the circulation pump maintains the required membrane cross flow.
The mechanical design of the system is skid-mounted and pre-assembled for easy implementation.
OSN units are used in the fine and specialty chemical production, the oil and petrochemical industry as well as in the fragrence and food industry.
Several BORSIG OSN units have been successfully implemented in industrial processes in recent years.
Organic Solvent Nanofiltration
One of our innovative membrane technologies is Organic Solvent Nanofiltration (OSN), a new separation technology for the treatment of liquid process streams in the molecular range. OSN is a pressure driven process
that operates at moderate or ambient temperatures. The separation takes place in the liquid phase. No phase transition is required for efficient separation.
