Modular membrane filtration unit

GEA Membrane Skid up to 6.25 m³/h

GEA Modular Membrane Filtration System up to 6.25 m³/h, in excellent condition and barely used. This equipment was used for just two validation batches, and after that has been in storage. It is currently equipped with spiral-wound nanofiltration membranes but other membrane types can be used for microfiltration (MF), ultrafiltration (UF), etc.

The complete original manufacturer documentation is included in digital format, comprising the operating manual, process flow charts, wiring diagrams, certificates, inspection reports, and other relevant technical documentation.

The system is designed to process a maximum volume of approximately 100 m³ of product (feed) per day. An average feed flow rate of approximately 4 to 6 m³/h is assumed under the “16/4” or “20/4” operating regime (Explanation: “20/4” corresponds to 20 hours of filtration operation / 4 hours of CIP cleaning).

If, at a later stage, the daily processing capacity needs to be increased or the installed membrane surface becomes insufficient due to unforeseeable fouling effects, two empty slots are provided for retrofitting additional membrane housings. The piping and recirculation pump are already prepared for such an expansion.

The membrane unit is designed for a semi-automatic cleaning-in-place (CIP) procedure. The system includes the required valves for internal circulation of cleaning solutions, followed by system flushing.
