Cross-flow membrane filtration technology is quickly gaining global acceptance as an important manufacturing step in many of the process lines in the food, dairy, pharmaceutical/biotechnology and starch and sweetener industries worldwide. The ability to produce very specific separations at low or ambient temperatures with no phase change can, in many applications, make membrane filtration a much more cost-effective solution than more conventional methods such as rotary vacuum filtration or filter presses.
Membrane filtration is a pressure driven technology with pore sizes ranging from 100 molecular weight to 5 microns. The technologies included in membrane filtration are: Reverse Osmosis RO, Nanofiltration NF, Ultrafiltration UF, and Microfiltration MF
GEA Filtration offers a wide range of system and membrane types to allow each and every completely optimize their specific separation. The range includes a number of both polymeric and inorganic membranes:
- Spiral - Due to their compact layout and relatively large amountof membrane area per element, spirals are good cost-effective solutions to high volume applications with minimal or no suspended solids, with the primary advantage being both low capital investment and energy costs. They are available for all types of filtration from microfiltration to reverse osmosis.
- Tubular - Highly resistant to plugging, tubular membranes are typically used when the feed stream contains large amounts of suspended solids or fibrous compounds.
- Hollow Fiber Membrane - Extremely high packing density and open channel design; offers the possibility of backwashing from the permeate side, particularly suited for low solids liquid streams.
- Ceramic - Ideally used for value added or sanitary applications such as milk or fermentation broths as well as products requiring selective separations from fluid streams with extremes in pH, temperature or solvents.
- Stainless Steel - Rugged design, especially effective for demanding applications with aggressive process conditions or feed streams with elevated particulate solids or viscosity.

GEA is a global technology group operating in two major Business Segments:
- Process Engineering
- Process Equipment
- Customized Systems
Within these Business Segments our companies have specialized in process technology, refrigeration, mechanical separation, thermal and energy technology as well as air treatment and dairy farm systems. They manufacture components, systems and complete process lines. In addition to standardized products, we particularly provide customized solutions tailored to our customer's specific needs. Founded in 1920, the Group is headed by the holding company GEA AG, Bochum, which went public in 1989. 200 operating companies in some 50 countries which are organized in seven divisions are controlled from here. GEA is among the three biggest engineering contractors in Europe.
In many product areas GEA companies are technology leaders. Our activities centre on
- the rationalized production of processed food for a steadily growing world population,
- the efficient use of non-renewable sources of energy and
- the conservation and preservation of the environment.
These three increasingly important challenges create growing long-term demand and develop markets worldwide.
The turnover in the business year 2006 amounted to about EUR 4.3 billion. The result before taxes and interest (EBIT) lay with 298.2 million euros. To the 30th June, 2007 the enterprise occupied about 19,000 employees. The corporation GEA Group is listed in the MDax.
Cross-flow membrane filtration technology is quickly gaining global acceptance as an important manufacturing step in many of the process lines in the food, dairy, pharmaceutical/biotechnology and starch and sweetener industries world wide. The ability to produce very specific separations at low or ambient temperatures with no phase change can, in many applications, make membrane filtration a much more cost-effective solution than more conventional methods such as rotary vacuum filtration or filter presses.
Membrane filtration is a pressure driven technology with pore sizes ranging from 100 molecular weight to 5 microns. The technologies included in membrane filtration are:
- Reverse osmosis - Reverse osmosis (RO), sometimes called hyperfiltration, describes the tightest of these molecular-level separations. In reverse osmosis, hydraulic force is applied in excess of the natural osmotic pressure of a solution to provide the driving energy for water molecules to diffuse into and through the membrane. Typical operating pressure can be in the hundreds to even a thousand pounds per square inch (25 to 68 bar). RO membranes are generally characterized by their ability to reject sodium chloride (NaCl) at given pressure, temperature, and concentration conditions. Typical rejection values can be on the order of 98 to 99.5%.
- Nanofiltration - Nanofiltration (NF) is the next, more open cross-flow membrane filtration type. In solutions of mixed ionic species, monovalent ions will tend to permeate (pass through) the membrane whereas divalent or multivalent species will tend to be highly rejected at the membrane interface. Since some ionic species, the monovalent ions, are transmitted through the membrane, the difference in chemical potential between the two solutions is less and therefore lower driving forces are required. Hence, typical NF operating pressures may be only one to a few hundred pounds per square inch (7 to 40 bar). NF membranes are generally characterized by their ability to retain a divalent ionic species, often magnesium sulphate (MgSO4) or calcium chloride (CaCl2). Since more variability in applications exist with NF, retention of MgSO4 might range from around 80% to 98%.
- Ultrafiltration - With ultrafiltration (UF), the membranes comprise a discrete porous network. As a mixed solute solution is pumped across the membrane, smaller molecules pass through the pores while larger molecules are retained. We end up with one solution depleted of larger molecules, the permeate stream, and another enriched of larger molecules, the retentate. The open membrane structure means that mass transfer is now more flow dependent than pressure dependent, so operating pressure is further reduced. Typical operating pressures for UF are tens of pounds per square inch to a hundred or so (1 to 10 bar). Membrane classification convention shifts to atomic mass for UF membranes. Molecular weight cut-off (MWCO) is generally expressed in standard dalton (Da) or kilodalton (kDa) units. For example, a 10 kDa membrane would highly retain molecules of that molecular mass or greater while highly permeating smaller molecules. While this system is inherently flawed since the atomic mass does nothing to describe the actual size or geometry of a molecule, it remains the standard convention for UF membrane classification.
- Microfiltration - Finally, microfiltration (MF) describes the coarsest of filtration in the cross-flow membrane filtration range. Membrane porosity is, at last, conventionally depicted as a distance measure generally from a fraction of a micron up to a micron (10-6 m) or so. Large and small molecules then can be separated from very large or complex molecular structures. Typical operating pressures for MF are a few pounds per square inch to perhaps one hundred (0.5 to 6 bar).
Laboratory and pilot plant activities have been a vital part of the customer service offered by GEA Filtration through the history of the organization. GEA Filtration has facilities in selected locations worldwide for testing customer products and developing new processes that involve the core technologies of GEA Filtration, i.e. microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Over the years, a considerable amount of product knowledge has been accumulated. Pilot plant testing together with industrial plant experience has always been and will remain the basis for successful new projects that involve areas of GEA Filtration technology. To highlight the different applications we have divided our target market into these industrial segments:
Membrane filtration processes are generally differentiated by their ability to separate molecules and particles of different sizes. The core element is the barrier structure, separating the liquid into two compartments. This structure, called a membrane, acts as an active or passive barrier for the product - separating and transporting from the feed side to the permeate side.
GEA Filtration plants and systems are renowned for their design, engineering, process quality and efficiency.
