Cogeim filters are specially designed for solid-liquid separation.
By adding an heating system to the side walls, introducing an heated agitator and operating under vacuum conditions, they can be transformed into filter - dryers. A filter - dryer can process a concentrated slurry and discharge a dry powder.
Cogeim Filter-Dryers are deep bed, solid - liquid separation systems that use a filter screen to promote the development of the filter cake. Use of nitrogen above the cake and of vacuum underneath the filter mesh, can improve the filtration process.
The supply of a heating fluid to the jacket in combination with vacuum inside the vessel generates the appropriate conditions for solvent evaporation and thus for wet cake drying.
