Pilot membrane filtration units PiloMem

 

Concept and design:
 
PiloMem units are designed for piloting of pressure driven membrane processes with typical batch sizes of 20-500 litres. All sorts of membrane modules in industrial scale can be used. The units are built in a stainless steel rack. Various membrane modules can be used on an industrial scale. The systems are installed in a stainless steel frame on rollers with a maximum base area of 80x120 cm and a maximum height of 2m. They can be used for the pressure-driven membrane processes microfiltration, ultrafiltration, nanofiltration and reverse osmosis, at pressures up to 40 bar and in special designs up to 80 bar. The type PiloMem I has a pump that generates pressure and cross-flow, PiloMem II is a 2-pump system, with a smaller pressure generating feed pump and a pump in the membrane loop that generates high cross-flow for larger membrane modules.

The membrane modules are interchangeable. We offer the suitable modules for ceramic membranes and polymeric spiral-wound membranes, which we have optimized especially for minimal dead volume.
The design of the systems is particularly focused on: Easy emptying, good cleanability (CIP) and low minimum working volume with the largest possible membrane area.
Concentration and diafiltration can be carried out automatically, via PLC or hardware-controlled. All the necessary measurement technology is integrated in the systems, so that any external feed container can also be coupled.

GMP membrane separation unit for organic solvents (ATEX) ChroMem

 

ChroMem units are similar to the PiloMem systems but GMP compliant, ATEX  certified for use in Ex Zone II and suitable for operation with pure organic solvents and for the pressure-driven membrane processes microfiltration, ultrafiltration, nanofiltration and reverse osmosis up to 40 bar. Typically they are equipped with nanofiltration membranes and used e.g. in combination with preparative chromatography, for concentration and/or solvent change. There are two standard system sizes, the smaller ChroMem I and the larger ChroMem II.

The membrane modules are interchangeable. We offer the suitable modules for ceramic membranes and polymeric spiral-wound membranes, which we have optimized especially for minimal dead volume.
The design of the systems is particularly focused on: Easy emptying, good cleanability (CIP) and low minimum working volume with the largest possible membrane area.

Concentration and diafiltration can be automated. All measurement equipment also for this operation is integrated in the unit therefore no external signals are needed. The units are temperature contolled and pump speeds are electronically controlled.
