Background and purpose: Microbial electro-Fenton system as a novel technology can be employed in removal of resistant organic pollutants along with generation of renewable electrical energy through the activity of anaerobic microorganisms. This study aimed at investigating the performance of this process in treatment of synthetic wastewater containing tetracycline and generation of electricity ...

In this paper, the electrical consumption of Hamedan University is derived of the bills, Then with defining of fuzzy Bus Thermal Coefficient objective function for heating, the amount of available heat selling to university consumer that is produced by Biomass CHP plant is calculated. With the capacity determination of Biomass CHP plant to provide Thermal and electrical energy of university and...

Train braking energy regeneration in urban electrical rail transportation systems can reduce energy consumption and operational cost of the system. In this paper, optimal design of an onboard energy storage system (OESS) with volume constraint is presented for urban electrical rail transportation systems (ERTS). Onboard super-capacitors are considered as the storage system. The objective functi...

well-designed lighting decreases accidents and diseases of eyes and can increase productivity and concentration. increase of energy price and a high proportion of electric lighting energy consumption in buildings due to defects in designing and maintenance led to desirable lighting to be reduced. one of our challenges in providing health and quality of lighting is lack of economic justification...

Saving energy is one of the most important challenges of todaychr('39')s world. Reducing electrical energy consumption in compressed air systems is one of the essential requirements for designing these systems. When using domestic air conditioners (dual air conditioners) in very hot areas (Khuzestan) their performance decreases and electric current consumption increases. Therefore, the use of n...

−Finite element analysis is used to compute the current distribution of the human cochlea during cochlear implant electrical stimulation. Genetic algorithms are then applied in conjunction with the finite element analysis to optimize the shape of cochlear implant electrode array based on the energy deposited in the spiral ganglion cells region. The goal is to improve the focus of electrical ene...

Introduction and purpose: The olive oil industry wastewater contains significant amounts of oil and this can cause serious problems if it is discharged into the wastewater treatment system, so the oil in the wastewater must be removed and seperated prior to any action. Therefore, the oil in the sewage should be removed and separated prior to taking any measure. There are several ways to remove ...
