Disinfection of dairy wastewater effluent through solar photocatalysis processes

Solar photocatalysis of a recalcitrant coloured effluent from a wastewater treatment plant.

A photocatalytic study of a coloured effluent from a wastewater treatment plant was carried out in a pilot plant using compound parabolic collectors (CPC) in order to find out the best conditions for colour removal, since the discharge limit for this parameter is not achieved after conventional wastewater treatment. The interaction between ultraviolet natural radiation and TiO(2) strongly enhan...

Electrochemical disinfection of secondary wastewater treatment plant (WWTP) effluent.

In this work the electrochemical disinfection of the effluent of a secondary wastewater treatment plant is investigated. In the experimental work, performed on-site with real effluents of the WWTP located in Vuelta Ostrera (Cantabria, Spain), boron-doped diamond (BDD) electrodes were employed. The initial concentration of E. coli in the effluent of the WWTP varied in the range 1.3 x 10⁴-5.2 x 1...

Hydrogen producing water treatment through solar photocatalysis†

Hydrogen is being intensively investigated as a new energy carrier that stores and transports energy obtained from renewable energy resources (e.g., solar and wind power) to the point of use. In particular, efficient methods that can convert solar energy into hydrogen are being actively sought. One of the ideal methods is solar hydrogen production from water splitting that can be driven by phot...

Uv Disinfection of Treated Wastewater Effluent: Influence of Color, Reactivation and Regrowth of Coliform Bacteria

Disinfection is a very important unit process to deactivate coliform bacteria in treated wastewater. However, regrowth potential of coliform bacteria raises human health and safety concerns associated with reuse of treated wastewater in various applications. Both post chlorination and post UV disinfection regrowth have been reported in the literature. In view of increasing use of recycled waste...
