UV Photodegradation and Anaerobic Digestion of MB Dye

Abstract:

Ultra-Violet (UV) photocatalytic degradation and anaerobic digestion (AD) were applied in the treatment of methylene blue (MB) dye. South African natural zeolite was used as a catalyst support and biomass support in the photocatalysis and AD process respectively. It was found that UV photocatalysis pre-treatment of MB dye before the AD process improved its biodegradability. This resulted in higher biogas production coefficient compared to the non-UV pre-treated MB dye.
