Abstract Desalination is a process of eliminating salt and other minerals from seawater which turns it to a safe usable water. This study showed the generation of clean water from seawater using carbon-coated solar absorber in two different solar still body colours which are transparent and black solar still, under direct solar exposure at approximately 1.2 kW/m2. The efficiency of carbon-coated solar absorber in the transparent and black solar still was computed, while the clean water collected was examined for its pH and salinity. Carbon-coated solar absorber in black solar still exhibit the highest efficiency at around 35.71%, where the pH and salinity of the collected clean water was substantially reduced to usable water at 6.55 and 62 ppm, respectively.

Abstract: The Effectiveness of Rice Husk Ash Filter to Reduce Turbidity of Martapura River Water. Martapura River water is used by people living on riverbanks for cooking, washing, bathing, and others. The main problem of Martapura river water is the turbidity which is relatively high so it needs to be processed first before use. The preliminary test conducted on August 15, 2016 shows the value of turbidity of Martapura river water at 38.9 NTU. This research was an experimental research with the one group pretest and posttest design which aimed to determine the effectiveness of the filter to reduce the turbidity of Martapura river water. The medium used was rice husk ash with variation of thickness were 13 cm, 26 cm, and 39 cm. The effectiveness of filtration was determined by comparing the turbidity of water filtered with standards. The turbidity of Martapura river water before filtered was 35.7 NTU. After filtered by 13 cm, 26 cm and 39 cm filter, the turbidity of water decreased consecutive to 2.97 NTU, 1.17 NTU, and 0.95 NTU, with decreasing percentages respectively of 91.7%, 96.7% and 97.3%. All filtered water showed turbidity fulfilled both the standar of clean water and drinking water so that rice husk ash filter was effective decreased turbidity of Martapura river water. Filtered water is recommended to be cooked first to boil when used for drinking water because the number of bacteria of Coli has not been studied. Further research needs to be conducted by adding other parameters according to water quality standard

Clean water is one of the human's main needs. Dug well water in Tombang, used for various needs. However, the dug well water has been polluted by E. Coli bacteria which is suspected to be due to the disposal of rubbish and waste carelessly and also the distance of latrines and dug wells that are very close together. Therefore it is important to do water purification using agricultural waste that is not utilized. The analysis showed that the purification of dug well water in Tombang with rice husk charcoal had reduced E. Coli bacteria by 55.6% with MPN pattern 1-0-3 so that the MPN value was 11/100 mL of sample.

This paper presents the synthesis of silica (SiO2) from rice husk at different firing temperatures. Due to the environmental awareness and to reduce air pollution, agricultural wastes specifically rice husk is used to produce SiO2. Silica was prepared by washing with clean water without any chemical treatment. The rice husk was fired at 700, 800, 900, 1000, 1100 and 1200°C. In order to determine the effect of firing rice husk at different temperature, X-ray Diffraction (XRD) analyses were conducted. Crystalline silica were obtained at 1100°C and 1200°C firing temperature. At 900°C and 1000°C firing temperature, silica was observed to be in a transitional phase of amorphous into crystalline or it called as semi crystalline. However, at 700°C and 800°C silica remains to be in amorphous phases.

Abstract Today, availability of clean water is hard as the residents are expanding and moving fast to achieve rapid urbanization as a result need for clean water has been raised. Solar stills are the solution to desalinate to obtain pure water. This paper represents the theoretical and experimental study of tubular solar still with and without fins. The reading was recorded from 8:00 AM to 6:00 PM. Efficiency of TSS with fins and without fins are 23.39% and 13.76% respectively. The rate of irreversibility from the basin of TSS with flat is higher than TSS with finned absorber. Similarly, the rate of irreversibility from water is significantly reduced using finned absorber. Also, the exergy efficiency of TSS with finned absorber is higher compared to TSS with flat absorber.

Purpose:The supply of pure fresh water is becoming a rising issue is many areas of the world. Clean water being a basic requirement is still unavailable to a large number of people. The fast development and growth in population and agriculture has helped to increase the need of clean water. The solar distillation is one of the most cost efficient ways to accomplish this. Methodology:When water evaporates from the basin of the still, it leaves the various impurities behind resulting in clean palatable water. Solar stills have a comparatively low yield but can be used to provide safe water options to rural areas of the world. To increase the yield of the solar still nano Al2O3 fluid is used,which is prepared using a dispersant of Sodium Dodecyl Benzene Sulphonate (SDBS). The still is a double slope basin type solar still with black paint coating on the inside and external reflecting mirrors, to enhance the yield. Main Findings:This project compares the efficiency and output of double slope solar still with and without the nanofluid. The single basin double slope solar still was fabricated using low cost durable materials and the 0.01 vol. % Al2O3 water based nanofluid was prepared. The results showed a positive outcome of a 15% increase in the rate of distillate collected with the use of nanofluids. The payback period was calculated to be less than 2 weeks without nanofluid and one week with the use of nanofluid. Implications:The present study is useful for obtaining pure drinking water at remote locations in Sultanate of Oman where solar energy is abundance. Novelty of Study: Nanofluids are used to enhance the distillation rate when compared to the conventional solar stills.
