KeraNor has, through the years, been working with international industries in a number of industrially driven projects. Below is a brief description of some of these projects:
Ceramic filters for oil well drilling filtration
During drilling of oil wells there is a need to separate of the rock fragments (sand) from the formation water. This can be done with ceramic filters.
Here also, the high temperature properties of the KeraNor ceramic filter are important as well as the good wear properties.
Porous ceramic plates for bipolar fuel cell and battery applications
For bipolar applications within fuel cells and batteries, porous plates may function as hosts for conducting materials impregnated into the pores allowing the electrode direct contacted with the conducting phase on both sides of the plate. This allows the current path between the two electrodes to be very short, hence reducing the internal resistance of the cell (and battery).
Here also, the high temperature properties of the KeraNor porous ceramics are important as well as the good mechanical properties.
Ceramic filters for membrane emulsification
Ceramic filters are well suited for membrane emulsification. Ceramic filters are delivered with pore sizes in the nanometre range, and with a very sharp pore size. This is useful for making emulsions with small and consistent size of the dispersed phase, thus improving the stability of the emulsion.
Ceramic functional filters for removal of heavy metal ions
Modified electro dialysis (MED) is a CEDI technology suitable for removal of heavy metal ions, as well as precious metal ions and radioactive metal ions.
Ceramic MED filters have the advantage that they are mechanically very stable, can withstand high temperatures, and cannot easily be influenced by radioactive radiation. Ceramic MED filters can be surface modified and grafted with active groups for capturing the wanted ions.
Ceramic filters for high temperature (WFI) water filtration
The use of KeraNor ceramic filters for production of WFI (Water For Injection) applications can simplify the process and reduce costs.
The ceramic WFI filters need to withstand temperatures in excess of 150°C, and special care must be taken in order to avoid leakage from the "dirty" feed side into the "pure" WFI water side.
Depending on the nature of both the continuous and dispersed phases, the ceramic filters can also be made either hydrophobic or hydrophilic.
