PureSep MF membrane filtration systems

Clarification is a critical stage in the manufacturing of alcoholic beverages (such as beer, wine and cider), vinegar and fruit juice. It’s important that suspended solids and microorganisms are removed to reduce haze, produce a standardised taste profile and improve shelf life. Membrane filtration provides effective, efficient and high-quality clarification as part of wider filtration processes.

Traditional, two-stage diatomaceous earth (DE) and sheet filtration clarification methods are labor-intensive, inconsistent and wasteful, which can lead to increased operating costs and reduced yields.

Envirogen’s PureSep MF membrane filtration systems – including beer membrane filtration (BMF) – provide superior, high-quality clarification and increased yields in a compact modular design.

Membrane filtration equipment specially designed for the clarification of alcoholic beverages, fruit juice and vinegar

PureSep MF is our next-generation range of hollow fiber membrane filtration systems. Built on the success of our PureFlow and installed in factories across Europe, Africa and the Caribbean, this new range has been specifically designed for beer membrane filtration and the clarification of wine, cider, vinegar and fruit juice.

PureSep MF systems are single-step, membrane filtration solutions, designed to improve product quality and consistency while reducing costs and waste streams. The PureSep MF 100 model is optimised for the clarification of wine, cider, vinegar and fruit juice, while the PureSep MF 600 model is specifically designed for beer clarification.

PureSep MF 600 single-step, membrane filtration solution, specifically designed to improve beer quality and consistency while reducing costs and waste streams.

Each system includes Envirogen’s own Envi-BMF (beer membrane filter) or Envi-WMF (wine membrane filter) units. Each hydrophilic polyethersulfone (PES) hollow fiber membrane features an extra-wide, 1.5 mm lumen for excellent solid retention capacity and superior filtration quality.

Easy operation and straightforward maintenance are key to the PureSep MF system. Single-stage clarification is achieved with no additional treatment steps or additives. Cleaning protocols are automatically scheduled when the filters become saturated and require no manual intervention or hazardous cleaning fluids. The removal of chemical costs and the reduced labour requirement deliver significant efficiency savings while reducing environmental impact.

PureSep MF membrane filtration systems are the latest evolution of our tried and trusted PureFlow (crossflow filtration) models:

Membrane filtration equipment built for customization and integration

The PureSep MF range is based on a modular design and can be fully customizable to meet manufacturers’ exact requirements. The compact, skid-based systems slot easily into existing processes and even congested operational environments.

PureSep MF 100 and 600 models can operate as standalone units, provided with a complete control system and Siemens PLC touchscreen human-machine interface (HMI) as standard. With integration becoming an important feature of modern manufacturing processes, PureSep MF systems can be easily connected to supervisory control and data acquisition (SCADA) systems for complete control and even remote monitoring.

Futureproofed, modular skid designs that grow with your business

PureSep MF membrane filtration systems are fully customizable with the flexibility to change and grow as your production demands evolve. Manufacturers can choose the configurations and bolt-ons that achieve process-specific clarification standards without the cost of a fully custom-made system.


Expandable skid design

PureSep MF’s flexible skid design enables additional membranes to be added as production demands increase.

Filtrate back pulse bolt-on

A filtrate back pulse unit can be added for challenging products. The system reverses the filtrate flow to breakdown the gel layer inside the membrane lumen. The disruption decreases trans-membrane pressures and increases production volumes.


Feed and filtrate tanks

Separate feed and filtrate tanks can be added for independent wine conditioning. Vessels are pressure-rated for isobaric operation and include an internal spray ball for clean-in-place (CIP) operation.

Clean-in-place bolt-on

CIP chemical dosing tanks, bunds and associated instrumentation can be added to PureSep MF skid for independent cleaning of the membranes and associated tanks. The automated cleaning protocols reduce chemical handling and associated health and safety risks.
