Microbial fuel cells (MFCs) have been used to produce electricity from different compounds, including acetate, lactate, and glucose. We demonstrate here that it is also possible to produce electricity in a MFC from domestic wastewater, while atthe same time accomplishing biological wastewater treatment (removal of chemical oxygen demand; COD). Tests were conducted using a single chamber microbi...

background: entry of untreated wastewater of wool scouring factories has been associated with many environmental hazards because of high rate of pollution. presently effective treatment methods and reducing the costs of operation and maintenance from treatment units have always been under the attention of this industry owners. the aim of this survey is to present a suitable method for the treat...

Biological nutrient removal (BNR) technology can suffer poor performance or complete failure due to the fastidious nature of the bacteria used in the system. The bacteria involved necessitate strict operating conditions, multiple zones with one or more recycling lines, carbon source augmentation, and efficient aeration. For wastewater treatment plants receiving significant combined sewer overfl...

Microbial fuel cells are obtaining increased attention in wastewater treatment technology because of provision of effective treatment in presence of a low organic load through continuous electrical power supply. This paper studies the voltage reutilization performance of a microbial fuel cell using recycled wastewater from its treatment process as an anodic fuel. The experimental results show t...

Microbial fuel cell (MFC) technology is promising for wastewater treatment because it enables recovery of clean electric energy as wastewater organic matter is oxidized. The preferred oxidant is the oxygen in air because it is cheap and readily available, but the efficiency of oxygen reduction is constrained by operating conditions (low oxygen solubility, temperature and mostly neutral pH). Con...

Ammonium ions wastewater pollution has become one of the most serious environmental problems today. The treatment of ammonium ions is a special concern due to their recalcitrance and persistence in the environment. In recent years, various methods for ammonium ion removal from wastewater have been extensively studied. This paper reviews the current methods that have been used to treat ammonium ...

Water supply and sanitation demands are foreseen to face enormous challenges over the coming decades to meet the fast growing needs in a global perspective. Significant growth in the industry is predicted and membrane separation technologies have been identified as one of the possible solutions to meet future demands. Application and implementation of membrane technology is expected both in pro...

Wastewater reclamation is an upcoming approach that will significantly affect wastewater treatment systems. Despite the fact that technology for treating wastewater to an effluent water quality that meets various quality standards for reuse is already available and applied, the reuse of water is not just a simple and straightforward road. Significant additional energy and civil infrastructure i...

The wastewater at Sukinda chromite mines (SCM) area of Orissa (India) showed high levels of toxic hexavalent chromium (Cr VI). Wastewater from chromium-contaminated mines exhibit potential threats for biotic community in the vicinity. The aim of the present investigation is to develop a suitable phytoremediation technology for the effective removal of toxic hexavalent chromium from mines wastew...

Wastewater treatment is essential to protecting the environment and human welfare. Water is a resource that is fundamental to human life, which makes taking action to protect the resource on the forefront of research. Treated wastewater effluent is a possible source that can pollute receiving water bodies and cause contamination. It is often discharged into larger bodies of water that are used ...
