The present work deals with the photocatalytic degradation as a method for pre-treatment of the effluent from a textile industry containing various dyes and their intermediates which are non-biodegradable. The textile effluent was subjected to photocatalytic degradation under UV irradiation in the presence of TiO2 as catalyst and the process parameters for maximum degradation were determined. Optimisation of catalyst dose and pH was carried out and the effect of addition of oxidant H2O2 on the degradation efficiency was also studied. The effectiveness with which the photocatalyst can be recycled was also assessed to ensure the economic viability of the process.
