Installation for producing functionalized nanocomposite permselective materials

Summary

A Romanian research institute has developed a pilot installation for producing functionalised nanocomposite permselective materials. The institute is looking for a company interested in the industrial scale construction of the installation and the construction of membrane-based equipment for the purpose of commercialization, under a technical cooperation or commercial agreement with technical assistance.

Description

The installation allows a wide range of such materials, with reproducible structural, electroconductive and hydrodynamic characteristics. In most modern technologies that have in their phases the separation of various compounds from liquid media, classical filtration has been replaced by processes that have as a central element of separation a nanomaterial permselective material known as the membrane. Transport phenomena, flowing into porous media, separation under environmental and environmental conditions, and a wealth of practical applications have made the membrane field grow at an exponential rate. It is the natural consequence of the optimal ratio between the technical and economic factors that characterize the membrane processes: • technical factors: selectivity of separation, reliability of technologies and related facilities, product quality, productivity and energy consumption; • economic factors: the cost of installations and equipment, the cost of operation and maintenance, the price of the final product. The main advantage of membrane processes is the ability to separate thermolabile compounds, since separations are carried out at ambient temperature. Thus, the problems of separation and concentration of compounds whose properties related to the structure and implicitly to the mode of action are irreversibly altered at a certain temperature are solved. In the last time, the use of membrane processes has been imposed (at the expense of classical separation / concentration processes) in the following areas: -biotechnologies - for the separation and concentration of biologically active compounds from existing complex mixtures in plant extracts, processing of biosynthetic environments, concentration of fruit juices, removal of microbiological load from wine (cold sterilization, without sulphites addition, etc);- treatment of surface or deep water for the purpose of potable water; -take of drinking water in sea water through reverse osmosis; The installation for continuous flow of nanocomposite materials comprises the following subassemblies (figure 1): - the film generation module (1) - the coagulation tank (2) - the reaction tank (3) - the thermostate module (4) - the coagulation solution feed module (5) - the reaction mixture feeding module (6) - the wastewater collecting an neutralization tank (7). The nanocomposite membranes were achieved by successively following the following stages of the technological flow: in the first step, the polymer is dissolved in the solvent, after this the adjuvants needed to adjust the viscosity are added to the solution; the final solution obtained is filtered and de-aerated; this is introduced into the film generation module, after which the process of forming the membrane begins by applying the polymeric solution to the polyester support, immersing the polymer film in the coagulation bath, passing the membrane formed in the reaction vessel in which the composite membrane is made, the washing and finally the conditioning of the obtained membrane. - industrial wastewater treatment; -cleaning of levigates generated by municipal landfills. The technical problem solved by the invention consists in development of an installation for producing functionalized nanocomposite permselective materials with overlapped polymeric structures. The materials are resulting from the chemical reaction forming of one polymer into the training process network through a physical process of another chemically inert polymer by phase inversion. Electroconductive and hydrodynamic characteristics are reproducible and usable both for baromembrane processes as well as in electrochemical processes for bioseparation and bioassay. A Romanian research institute is looking for a company interested in the industrial scale construction of the installation for the purpose of commercialization for technical and research cooperation agreement with technical assistance.

Advantages and innovations

The installation and technology used has the following advantages: - is producing the functionalized nanocomposite permselective materials with reproducible electrically hydrodynamic and structural characteristics - modular construction, simple, easy to operate and serviced - is allowing production of functionalized nanocomposite permselective materials, with various characteristics, in the same cycle of operation. The installation is designed for producing functionalized nanocomposite permselective materials, usable both for baromembrane processes as well as in electrochemical processes for bioseparation and bioassay; it is solving the problems related to the fact that the multilayer permselective materials obtained using other technologies consist of two or more layers physically deposited on each other, with applicability in most cases restricted to the field of barometric processes.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
