Parametric Studies

There is an ever increasing need to provide clean and portable drinking water in developing countries because of the poor quality of water, which causes various water borne diseases killing millions of infants and elderly people every year. There have been a lot of recent developments in the field of solar enabled water distillation where pure water is being generated. But a majority of the system use some type of external energy source for the system to run on which might make it efficient but can cause dependence on energy sources. The power of the Sun can be effectively harnessed and used as heat and light source for efficient steam generation. One of the challenges is to develop a low cost system which can perform at par with the best and extravagant systems. This paper investigates the performance of the solar distillation system when activated carbon nanoparticles are used along with brine and other sources of impure water so as to obtain clean water. The activated carbon nanoparticle which are an efficient and cheap mode of water purification enhanced the productivity of the system by 190% when compared to saline water due to its steam generation properties. A solar simulator of 1KWm2 was used to simulate the sun. Various parameters like the variation of air flow on condensation rate, height of fluid on vapor production rate and the temperature variation of the system are evaluated. Parametric studies of the effect of water quality and salinity were performed. It was determined that the optimum output rate of distilled water was 240 grams (6000gday.m2) was determined by the system from the parametric studies and the system is feasible and cost effective to be used in real world application. All of these standout features make the system a low cost option which can tackle the clean water dilemma in developing countries.

Land Holdings

The population of marginal farmers in India is bound to increase due to continued division of farm holdings. Characteristically, marginal farmers are having more family labours but the production and productivity of their land holdings is low. The foremost reason behind this is the erratic rainfall and lack of assure supplementary irrigation during long dry spells. This paper presents the scope and applicability of a diaphragm based treadle pump in Bihar where groundwater is abundant and available at shallow depths round the year. Therefore, this pump could be very useful for marginal farmers in improving production and productivity of their tiny piece of land, as it uses human power and can be operated by male and female of age group 32- 45 years and lifts water from a depth ranging from 0- 30 feet. The water saving technologies such as bucket kit drum kit etc. could be used with this pump to irrigate the crops with high water productivity.

Butanol Yield

MgO supported on activated carbon (AC) with a load ranging from 10% to 30% has been investigated as catalyst for the conversion of ethanol into butanol at 400 °C in a fixed bed reactor at different GHSV. Catalysts have been characterized by XRD, SEM/EDX, and N2 physisorption at 77 K. The high dispersion of MgO into the pores of the support provides strongly enhanced performance with respect to bulk MgO. MgO/AC catalysts have been also tested under wet feed conditions showing high water tolerance and significantly larger butanol yield with respect to an alumina supported Ru/MgO catalyst. After wet operation, the increased surface area of the catalyst leads to better performance once dry feed conditions are restored.

The main aim of the present study is to draw attention to the possibilities and to the measures of appropriate utilization of renewable energy to achieve what is called “water self-sufficient” for arid regions in Jordan. Also to put efforts of increasing the use of renewable energy sources to lower cost of potable water pumping and gives more economical benefits. Another aim of the current research is to utilize the new control algorithm and the developed computer capabilities in the field of sun tracking in order to improve the efficiency of solar distillers. The new tracking method is utilized for water distillation taking advantage of high possible concentration of parabolic trough collector to reach high levels of daily yield per square meter. The present research utilizes the techniques of image processing to catch the core of the sun as the target, also used artificial intelligence techniques to predict the sun position in abnormal conditions (i.e. cloudy, dusty, rainy). The results of sun tracking using image processing found to be accurate and reliable according to the self monitoring of the focus point validated by the solar radiation results. Water distillation yield shows high percentage output of distillate of about 65% of water supplied to distiller. Mechanical design was tested for high ability to withstand the extra loading. It was found that the output yield reached to noticeable levels, because of the use of the parabolic collector that promoted the solar still efficiency.
