MODEL AND FABRICATION OF AN INDIGENOUS WATER PURIFIER Vishal V. Patil1, Gaurav C. Pawar2, Yogesh A. Pansare3, Yogesh B. Pawar4, Rohan D. Hucche5 Dept. of Mechanical Engineering, G. H. Raisoni College of Engineering, Ahmednagar, India [1],[2],[3]&[4] Professor, Dept. of Mechanical Engineering, G. H. Raisoni College of Engineering, Ahmednagar, India [5] ---------------------------------------------------------------------***--------------------------------------------------------------------purifier consist of an unique design of solar Abstract - Even in 21st century millions of people pasteurizer combine with simple filtration unit. The in the developing countries suffer from water-borne disease. filtration system consist of two metallic containers Polluted water is causing health problems in the rural areas placed one at the top of the other one with a ceramic of India. Here the potential of solar energy to pasteurize the candle filter fitted at the upper containers bottom. water is investigated. Low cost indigenously available Lower container stores the filtered water & to cool materials have been utilized to design and fabricate a solar the hot water collected from solar pasteurizer, pasteurizer having a capacity of nine liters. The designed evaporative cooling system is implemented. The pasteurizer maintains water temperature in the range of whole purifier unit can be placed in suitable support 60oC to 70oC continuously for more than an hour which is made of wooden table. A funnel is connected with enough for deactivation of bacteria. The low cost and inlet pipe of the pasteurizer. A stop cock is fitted at operational simplicity of the pasteurizer make it affordable. the outlet connection of first metallic container. Vent Key Words: Pasteurization, Water Purifier, Solar holes are provided with collector tank and filter Energy, Water Treatment, Disinfection, Heating. container. A mercury thermometer is fitted at the outlet of water container. In the present work, we 1. INTRODUCTION report the design of a solar pasteurizer using low cost indigenous material. The efficiency of Polluted drinking water is causing many health pasteurizer has been under local environmental problems in the remote areas. Most commonly rural conditions. people face huge problem due to unavailability of safe drinking water. In many parts of the world, work 1.1 Performance Characteristics is already being carried out to use solar energy for purposes other than cooking. David and Robert 1) Latitude of Ahmednagar district, Maharashtra, (1984) investigated the potential of using solar India: 19. energy to pasteurize water. They heated water to a 2) Average intensity of solar radiation in temperature of 65oC in a box cooker. Razzak et al. Ahmednagar District, Maharashtra, India: 4.8 (1985) carried out a direct method for obtaining KW per sq. m pasteurization of contaminated water by using solar 3) Minimum intensity of solar radiation: 1.9 kW per energy. They designed a solar pipe collector and sq. m obtained a temperature of 63 to 78oC. Reddy and 4) Maximum intensity of solar radiation: 6.6 kW per Verma (1986) studied the scope of using solar sq. m energy in pasteurization of milk. Joyce et al. (1996) 5) Maximum water temperature attained during reported the thermal effect of equatorial sunshine on winter: 60°C. water samples contageted with high populations of 6) Maximum water temperature attained during coliforms. They investigated the feasibility of summer: 70°C. employing solar disinfection for highly contaminated 7) Capacity of filtration throughout the day during water. McGuigan et al. (1998) reported a series of winter: 9 liters. experiments to identify the inactivation process in 8) Capacity of filtration throughout the day during stored water, exposed to sunlight. Safapour and summer: 9 liters +9 liters = 18 liters (water filling Metcalf (1999) described a simple and reliable and collecting is possible two times). method that could be used to pasteurize milk and water with solar energy 1.2 Solar Pasteurization and Filtering Unit To fulfill need of rural people a new design of The solar pasteurizer unit of improved water purifier combine solar pasteurizer cum water filter has been is a newly developed solar pasteurizer, which designed.
