“…In spite of the good rain fall in the state of Maharashtra shortage of fresh water is observed and large quantity of ground water is the saline water [3][4][5][6]. R.K. Khanna et al [7] reported his findings about the water quality from the village Chui located in the state of Rajasthan. He observed that in this village nearly all the family members need to search the fresh water, collect it and store the same.…”

Experimental setup of the integrated parabolic trough collector (PTC) with solar still was developed. PTC was designed considering the solar geometry and the physical laws of parabolic shape and the concentrators. Test were conducted at the location with latitude 19.9975ON and longitude 73.7898OE. Theoretical analysis was done using ray tracing and engineering equation solver (EES) software while designing the system. PTC system was developed with dimensions of 1.5 m length, 1 m width and a concentration ratio (CR) of 21.22. Theoretical thermal efficiency was predicted as 48.1% whereas experimental average thermal efficiency is observed as 42.76%. The observed temperature difference between the vapor and the glass cover is about 17 °C and between ambient air and vapor is about 24.4 °C. Maximum water temperature in the conventional solar still was 64.6 °C where as for the PTC coupled solar still was 74.4 °C. PTC coupled solar still is having averagely 37% higher production rate. This has definitely added an advantage because of the higher energy absorption rate compared with the conventional solar still. PTC coupled solar still system has nearly 35% more heat absorption. Total embodied energy of the system is around 896.875 kWh. Total capital cost of the system is Rs. 41300/-. Total annual output of pure water is around 3 L/Day. Estimated energy payback period is around 2.29 years and the total carbon credit earned is Rs. 2165.38 per year.

“…Es por eso que en lugares donde hay fuerte irradiación solar y donde las fuentes de agua dulce son escasas se puede utilizar la destilación solar a pequeña escala comercial para abastecer a las pequeñas comunidades de áreas aisladas (Bouchekima, 2002) (Al-Hayek & Badran, 2004) (Khanna, Rathore, & Sharma, 2008) (Mboumboue & Njomo, 2016). Siendo el uso de energía solar para destilar y purificar el agua una tecnología de bajo costo y amigable al medio ambiente (Shatat, Worall, & Riffat, 2013) (Tiwari & Sahota, 2017).…”

This research allows knowing the Sector of bottled water in the district of Sechura, one of the 8 provinces of the Department of Piura-Peru. To assess by a proof of concept, water bottled obtained from the underground of Sechura has been processed and purified with filters and solar panels as a result from the Project financed by Innovate Peru-Fidecom with the Periche Company. Also, knowing its behavior with regards to the origin of the water consumed the assessment of the faucet and bottled water. The project starts because the lack of water and because the low quality of it in Sechura. Therefore, low supply in the area and high demand make feasible the initiative of extracting water from its underground. At the regional level, we are one of the countries with lower consumption per capita of bottled water. There is a great potential for demand reflected in the growth rate of more than 10% in the sector in the last five years. The market of Sechura, according to data from INEI, is comprised by 58,497 inhabitants of the urban area of 6 districts of Sechura. These constitute, by area of influence of the project, the main potential market. Research was performed to identify the consumer of bottled water in the area of influence of the Project, a representative research with 102 surveys and product tests to final users. Surveyed people were explained that the project consisted on the manufacturing of a pilot plant to sanitize the water from a spring source using solar power, a friendly system with the environment, sustainable over time using resources of the area. The trend is to use water from the faucet, mainly for cooking and hygiene, and bottled water for daily consumption featured in 20 liters bottle. Also, water studied have been performed through the People's Protection Office to the districts of Sechura, which have set its bad quality, and this study presents with low score provided by the surveyed people. The assessment to bottled water is mainly hygiene (61%), health (56%) and taste (50%). In surveys, it is shown that users in 87% are willing to take this new proposal of bottled water. Also, they value the regional origin of water and the care for their environment in 92%. The environmental value of the water is the recognition as an essential part of the system. It constitutes an opportunity for communication and positioning for the innovative company. Therefore, it is a demand in a brand introduction phase where promoting and distribution are essential, and should be focused emphasizing in the differential features of the product to create awareness and testing of the product. The water, being a vital product for consumption, has a strong acceptance. Therefore, the put in place of policies for an integrative management of the resource by authorities and better planning are necessary as part of a governmental commitment or private initiatives, and a change in one of them impacts in the other components of the system Keywords-bottleled water, Sechura, water quality Digital Object Identifier (
