  • Potential of membrane distillation – a comprehensive review

    Membrane distillation (MD) is a recent and unique separation technology, in use in the process industry. The process of separation in MD involves the simultaneous heat and mass transfer through a hydrophobic semi permeable membrane, using thermal energy. Consequently a separation of the feed solution into two components – the permeate or product and the retentate or the return stream occurs. MD ...

  • Optimization of permeate flux produced by solar energy driven membrane distillation process using central composite design approach

    Membrane distillation (MD) is considered as a relatively high-energy requirement. To overcome this drawback, it is recommended to couple the MD process with solar energy as the renewable energy source in order to provide heat energy required to optimize its performance to produce permeate flux. In the present work, an original solar energy driven direct contact membrane distillation (DCMD) ...

  • Exergetic analysis of passive and active solar stills

    This paper presents an exergetic analysis for passive and active solar distillation systems. The analysis is based on mass, energy and exergy balance equations, which has not been attempted in the past for active solar stills. In the present paper, it has been tried to compare the hourly exergy and thermal efficiency of passive and active solar stills. The values of hourly exergy and thermal ...

  • The effect of sponge liner on the performance of simple solar still

    In conventional solar stills, a part of the radiation is reflected by the inner wall surfaces to the still components and the remaining energy is stored by itself. The main objectives of this experimental study are: 1) to utilise the energy available on the inner wall surfaces of a still by using sponge liner; 2) to find the optimum thickness of sponge liner. Two single-slope solar stills are ...

  • Multiple floating porous absorbers type solar still: annual performance evaluation

    This paper describes an experimental work conducted in order to evaluate the annual performance of a modified single sloped basin type solar still. The modified still consists of a multiple number of blackened porous jute cloth absorbers, which are being floated on the basin water with the help of thermo–col insulations. Higher absorber surface temperatures are rapidly reached in this design, ...

  • Tungsten trioxide nanostructured electrodes for organic dye sensitised solar cells

    Tungsten trioxide (WO 3 ) nanospheres with diameter ranging from 10 nm to 500 nm were synthesised by a facile thermal oxidation process. By resistively heating metallic tungsten in oxygen atmosphere, WO 3 nanoparticles were produced in high yield. Optical, compositional, morphological and structural studies were performed by UV-VIS-NIR spectrophotometry, X-ray photoelectron spectroscopy ...

  • Carbon credits earned from a double slope active solar still under forced circulation mode

    Human life on land is vitally dependent on fresh water along with food and air. Many areas in the world do not have access to fresh water. Growing demands of freshwater resources are creating an urgent need to develop self sustained system to meet the demand. At present, many distillation methods are available like reverse osmosis, thin film distillation multi-effect fresh evaporation but they ...

  • Thermal modelling, validation and exergetic analysis of a hybrid Photovoltaic/Thermal (PV/T) active solar still

    This paper presents the thermal analysis of a self sustainable, new design of hybrid photovoltaic/thermal (PV/T) active solar distillation system. The experiments were conducted for 24 h (7am-7am) for the New Delhi (India) climatic conditions on typical days during the month of April 2006 for water at different depths (i.e., 0.05, 0.10, 0.15 m) in order to validate the experimental results, a ...

  • Feasibility investigation of coupling a desalination prototype functioning by Aero-Evapo-Condensation with solar units

    The rural regions of south Mediterranean countries suffer from problems of drinking water supply. However, the majority of these regions have important resources of brackish salt water. Thus, brackish water desalination on a small scale presents a potential solution to this problem. For this reason, a number of small desalination prototypes are being developed worldwide. Bourouni et al. have ...

  • Two proposals for unlimited fresh water

    The world water crisis may be more serious than generally appreciated. One reason for this is that the main response has been to increase storage of rain rather than to increase the amount of fresh water. Another is that fossil groundwater has been widely seen as inexhaustible. Two fresh water collecting systems are outlined here and it is argued that they have no ultimate limitation, either by ...

  • A review of the factors affecting sunlight inactivation of micro-organisms in waste stabilisation ponds: preliminary results for enterococci

    Waste stabilisation ponds (WSP) are efficient, cost-effective methods of treating wastewater in rural and remote communities in Australia. It is recognised that sunlight plays a significant role in their disinfection, however, due to the poor penetration of light in turbid waters it has been hypothesised that other mechanisms may also contribute to disinfection in WSPs. To date, studies have ...
