Definitions
- the invention relates to an improved crossflow filtration unit for separating substances by crossflow filtration of liquid media and obtaining the target substances in the filtrate and / or in the concentrate
- fluids such as liquids, emulsions, suspensions, beverages such as beer, wine, juice, water and milk, whey, beer wort, industrial and waste water, solutions in pharmaceutical, medical, cosmetic , Chemical, biotechnology, genetic engineering, environmental protection and laboratory areas. They can be used to extract valuable materials, separate substances such as macromolecules and biomolecules, to depyrogenize and sterilize solutions, to separate pollutants from the fluids, to filter and concentrate biological solutions , for the separation of microorganisms such as bacteria, yeasts, viruses and cell components, for the desalination of protein solutions and other biological media
- a feed liquid to be filtered flows tangentially over the surface of a filter material and is thereby split into a concentrate and a filtrate.
- a microporous membrane in the ultrafiltration and microfiltration range is generally used as the filter material
- the ultrafiltration membranes are characterized by medium pore sizes or exclusion limits which enable them to retain macromolecules, for example in the molar mass range between 500 and 1,000,000 Daltons, while the microfiltration membranes have medium pore sizes in the range between 0.01 and 10 ⁇ m.
- medium pore size or exclusionlimit
- EA Schezermann in chapter 4 3 3 "Membranes” in the manual of the industrial Fest Flussig-Filtration, published by H Gasper, Huthig Buch Verlag Heidelberg 1990, pages 250 to 262 used.
- the concentrate is discharged from the overflowing surface of the membrane and can be recycled so that it can be recycled Repeated overflow of membrane surface
- the filtrate flowing through the membrane perpendicular to the surface is discharged from the underside of the membrane.
- Target substances to be obtained can be contained in the filtrate (filtrate substances) and / or in the concentrate (concentrate substances).
- Crossflow filtration units are often used in the form of filter cassettes, such as They are described, for example, in DE-PS 34 41 249. They consist of a large number of adjacent filter cells, which generally consist of alternately arranged, flat blanks from a concentrate spacer to form an overcurrent gap for the feed liquid to be filtered, a first membrane system, a filtrate spacer to form a filtrate collection gap and a second membrane assembly.
- Each overcurrent gap communicates with an inlet for the feed fluid to be filtered and with an outlet for the concentrate, and each filtrate collection gap communicates with an outlet for the filtrate
- the concentrate substances which are excluded from passage through the pores of the membrane due to their size, should be rinsed away from the surface so that they do not clog the membrane pores for permeation of the filtrate and the filtrate substances
- the membrane surface overflows in various ways with a cover layer, which usually affects the filtration performance, the yield of target substances and the service life of the crossflow filtration unit
- the invention is therefore based on the object of proposing an improved crossflow filtration unit which is distinguished by improved filtration performance and a high product yield
- the problem is solved by the features specified in the characterizing part of claim 1.
- Advantageous developments of the invention are solved by the features of the subclaims
- the improved crossflow filtration unit serves to separate substances of a feed liquid into filtrate substances of a filtrate and into concentrate substances of a concentrate.
- a feed liquid into filtrate substances of a filtrate and into concentrate substances of a concentrate.
- It consists of several sequences of a flat filter material, a filtrate collecting gap, a further flat filter material and an overcurrent gap in such a way that the filter materials with their back surface limit the filtrate collection gap and with its front surface the overflow gap and each filtrate collection gap is equipped with at least one outlet for filtrate and each overflow gap with an inlet for the feed liquid to be filtered and with an outlet for the concentrate.
- the filter material consists of two superimposed microporous membrane layers i the membrane system facing the filtrate collecting gap has an average pore size in the range of an exclusion limit of 1000 daltons to 1.2 ⁇ m, which excludes the concentrate substances from passage through this membrane system and the membrane system facing the overcurrent gap is at least one larger by a factor of 1.3 has medium pore size, preferably by a factor in the range from 1.3 to 5 and particularly preferably by a factor in the range from 1.5 to 3.
- the crossflow filtration unit is designed as a filter cassette, the membrane systems of which consist of microfiltration membranes.
- a filter cassette is particularly preferred in which the membrane systems facing the filtrate collecting columns have an average pore size, which is selected from the range from 0.1 to 1.2 microns
- the filtration unit has only a sequence of an overcurrent gap, a flat filter material from the two membrane layers with the different average pore sizes and a filtrate collecting gap in such a way that the filter material delimits the filtrate collecting gap with its rear surface and the overcurrent gap with its front surface
- a yeast-containing cell suspension (Pichia) with a cell concentration of 6 ⁇ 10 6 yeast cells (concentrate substances) per ml, which contains a target protein with a molecular weight of 70,000 daltons ( Filtratstof ⁇ ) in a concentration of 127 mg / 1, filtered in the crossflow regime (circulation of the concentrate)
- the pressure values were 0.9 bar at the inlet for feed liquid, 0.4 bar at the outlet for concentrate and 0.1 bar at the outlet for filtrate
- Example 1 As a crossflow filtration unit according to the invention, a filter cassette with an overflowable membrane area of 0.4 m 2 is used, which has 13 overflow gaps and 12 filtrate collection gaps.
- the membrane systems adjacent to the filtrate collection gaps consist of a cellulose acetate membrane with an average pore size of 0.2 ⁇ m and the membrane systems adjacent to the overcurrent gaps consist of a cellulose acetate membrane with an average pore size of 0.45 ⁇ m.
- 7.3 l of the cell suspension were reduced to a final volume of concentrate of 1 1 concentrated
- the average filtrate flow was 0.875 1 / min x 2
- the filtration was ended after 18 minutes.
- a concentration of target protein of 106.6 mg / 1 was found in the filtrate. 238 mg / 1 target protein was determined in the concentrate.
- the yield of target protein in the filtrate was thus 72%
- a filter cassette of the prior art (Sartocon * from Sarto ⁇ us AG) is used as the crossflow filtration unit with an overflowable membrane area of 0.7 m 2 , which has 17 overcurrent gaps and 16 filtrate collection gaps.
- the membrane systems adjacent to the filtrate collection gaps consist of a single cellulose acetate membrane with an average pore size of 0.2 ⁇ m
