Endocrine Distruction Chemicals (EDCs) Degradation in an Advanced Oznone Membrane Reactor - Experimental & Modelling Study

A study of ozonolysis degradation kinetics of EDCs in two phase gas-liquid system has been performed in a semibatch reactor observing Total Organic Carbon (TOC) degradation. TOC degradation alone may not be a sufficient parameter because multiple/complex kinetic concept is needed. This has been accomplished with experimental work. Reaction perturbed evolution and decay of the initial substance and its degradation by-products have been observed based on Glasser-Hildebrandt concept. TOC degradation and multiple/complex reaction kinetic parameters have been determined from percentage TOC consumption and HPLC area response rationalization based on carbon balance. These kinetic information have been incorporated to model and simulate ozone membrane reactor system using (i) mass balance approach and (ii) widely used continuity equation. The derived model answers the values of the characteristic parameters such as efficiency, molecular weight cut -off and enhancement for EDCs remediation in ozone membrane reactor.
