Ion exchanging textile are used as organic supports for enzyme immobilisation in the aim to develop reactive fibrous materials able to be substituted to membrane systems in bioreactors or acting for instance as reactive bags for waste treatment devices, thus extending the range of their potential applications. Integration of this modified textile in the electrodialysis cell allowed simultaneous removal of urea and ions produced by the hydrolysis reaction. The reactor-separator systems were studied under different current densities.
