Ultrafiltration equipment on the basis of hollow fibre elements
Ultrafiltration module on the basis of cassette elements
1. Development of synthesis and production methods for the ultra-
and microfiltration membranes’ preparation based on a wide range of polymers:
2) Designing technological processes of membrane separation for liquid mixtures
3) Pilot systems and industrial units fitted with:
DEVELOPED AND INTRODUCED TECHNOLOGICAL PROCESSES OF MEMBRANE SEPARATION
1) The food-processing industry
2) Pharmaceutical industry
ULTRAFILTRATION MEMBRANES MIFIL represent
porous anisotropic a film with thin (0.5 - 5 µm) the active layer
basing on highly porous substructure from the same polymeric material.
The membrane is deposited on reinforcing support from a non-woven polyester
or propylene giving to it a necessary complex of mechanical characteristics.
The asymmetric structure provides a combination of high filtration efficiency
and solutes rejection. Membranes MIFIL are produced in the form of continuous
cloth in width of 400 mm, stored and transported in a dry kind. It is
possible to prepare the membranes in the form of plates, disks, cassettes
and other configurations.
MIFIL-AC - hydrophilic membranes on a basis cellulose diacetate. Membranes AC-50 and AC-100 are analogues of industrial membranes of series UAM, however, as against the last, have the increased productivity and are produced in a dry kind. Membrane AC-300 has no domestic analogues. Membranes of AC series are intended for fractioning, purification and concentrating of solutions of synthetic and natural high-molecular substances, colloids, the viruses, clarifying filtration in various industries. They are characterized low adsorption ability to protein substances, low blocking.
MIFIL-RC - high hydrophilic membranes on the basis of the regenerated cellulose. Distinguish low nonspecific adsorption ability to proteins, enzymes, low blocking and high stability to action of organic solvents, detergents, mineral oil.
MIFIL-PAN - moderate hydrophilic membranes on the basis of acrylonitrile copolymers, distinguished by high stability to action of fats, mineral oil. In comparison with cellulose, membranes on a basis polyacrylonitrile provide the high protein rejection. Membranes PAN-10 and the PAN-20 having a narrow pore size distribution, are recommended for separation of the solutions of proteins, biologically active substances, medical products. The membrane PAN-100I is specially developed for sewage treatment and has the high stability to contamination by dissolved or colloid compounds of iron.
MIFIL-PA - moderately hydrophilic membranes on the basis of aromatic polyamide. Are intended for ultrafiltration of foodstuffs, separation of the solutions of high-molecular and biologically active substances. Are analogues polysulfoneamide membranes of series UPM, however, as against the last, having narrower pore size distribution and the high chemical stability.
MIFIL-PS - moderately hydrophobic membranes on the basis of aromatic polysulfone. Surpass in stability to alkalis, the acids, washing agents other types of membranes MIFIL. Are recommended for using in biotechnology, food, pharmaceu-tical and other industries.
MIFIL-PA-M - a new type of the composite membranes received by surface modification of aromatic polyamide ultrafiltration membranes. Distinguish the high fouling stability, high rejection in relation to "average" molecules (1000-5000D). Are produced as cassette and hollow fibre elements.
