one of the most important concerns in tehran municipal landfill is the production of leachate and its potential for water resources pollution, this study was undertaken to examine feasibility of biological and physico/chemical treating of high-strength landfill leachate that was collected from tehran municipal landfill. average cod of the leachate in aerobic submerged membrane bioreactor is 68...

Small-scale photovoltaic-powered reverse osmosis (PVRO) desalination plants can provide fresh water to remote communities that do not have sufficient natural sources. The technical feasibility of such systems is well-established and the economics for specific locations have been addressed. Recently, generalized methods to evaluate their economic feasibility have been proposed. They show that th...

Solar power models are a crucial element of solar-powered UAV design and performance analysis. During the conceptual design phase, their accuracy directly relates to the accuracy of the predicted performance metrics and thus the final design characteristics of the solarpowered UAV. Likewise, during the operations phase of a solar-powered UAV accurate solar power income models are required to pr...

The use of modern high flux reverse osmosis membranes with low salinity feeds at high recovery rates, makes the measurement of fouling by flux decline difficult in practice. Early detection of fouling is important, because the onset of fouling occurs at a critical flux which is difficult to predict a priori. An alternative method, measuring the electrical properties of the membrane is proposed ...

The availability of freshwater and energy is a serious issue in remote islanded areas, especially at small scale, where there may not be the possibility to access grid and/or water distribution systems. In this context, polygeneration systems operating on basis local, renewable sources can an answer users’ demand for electricity, heating, cooling, domestic hot water. scope proposed paper was in...
