Renewable energy is an increasing need in our society. Microbial fuel cells (MFCs) represent a new method for treating wastewater and simultaneously producing electricity. In the present study, we demonstrated the feasibility of bioelectricity generation from brewery wastewater treatment using a mediator less MFC at different pH. We also demonstrated that addition of readily utilizable substrat...

Bangalore city hosts two Urban Wastewater Treatment Plants (UWTPs) towards the periphery of Vrishabhavathi valley, located in Nellakedaranahalli village of Nagasandra and Mailasandra Village, Karnataka, India. These plants are designed and constructed with an aim to manage wastewater so as to minimize and/or remove organic matter, solids, nutrients, disease-causing organisms and other pollutant...

Background and purpose: Nowadays, rapid growth of car wash industries has led to a demand for wastewater reclamation. In this study, the hybrid process including electrocoagulation/flotation, sedimentation, and filtration were used in treatment of real carwash wastewater. Materials and methods: In this research, the sample was first entered into the ECF reactor, then entered the retention tank...

Backgrounds and Objectives: The base structure of total petroleum hydrocarbons (TPH) is made of hydrogen and carbon. Widespread use, improper disposal and accidental spills of this compounds lead to long term remaining of contaminations such as organic solvents and poly aromatic hydrocarbons (PAHs) in the soil and groundwater resources, resulting in critical environmental issues. In this s...

This work was aimed at studying the applicability of H2O2-based oxidation processes (namely H2O2/UV, photo-Fenton, and Fenton) for the treatment of six real aqueous wastes. These wastes derived from chemical, pharmaceutical, and detergent production, and were characterised by high COD (chemical oxygen demand) and, in four cases, surfactant concentrations: overall, about 100 tests were conducted...

The simultaneous partial nitrification, ANAMMOX and denitrification (SNAD) process was validated to potentially remove ammonium and COD from wastewater in a single, oxygen-limited, non-woven rotating biological contactor (NRBC) reactor. An ammonium conversion efficiency of 79%, TN removal efficiency of 70% and COD removal efficiency of 94% were obtained with the nitrogen and COD loading rate of...
