Ground Water Quality Index of Growing Smart City of Vadodara

Authored by Bablu Prasad

In current investigation ground water quality were monitored and assessed along the urban area of Vadodara including Gorwa, Nizampura, Harni, Gotri, Sayajiganj, Fatehgunj, Ajwa Road, Tandelja, Lal Baug, Makarpura and Tarsali monitoring station. Electrical conductivity, TDS, turbidity and alkalinity were found to be higher as compared to BIS standards of drinking water due to presence of ions such as Na+, K+, Ca2+, Mg2+, PO43-, SO42, NO3- and Cl-. Ground water quality index (GWQI) was calculated on the basis of BIS standards of drinking water specification. The calculated GWQI for these sampling stations ranges from 41 to 193 with a mean values 100. Based on GWQI, most the ground water samples have been included in good water to poor water category. GWQI analyses showed better ground water quality in the monitoring stations located in the underdevelopment area of the city than those stations located in the developed area. These results evidently indicated the use of water filtration or/and treatment before consumption of ground water of Vadodara city and it is also needs to be protected from contamination.

Integration of a Solar Thermal System for the Heating of an Office Space

Authored by R Kharchi

Given its geographical location, Algeria lends itself favorable to solar applications. The global solar radiation varies between 1700 and 2650 kWh/m2/year, for a duration of sunshine which is close to 3500 hours/year. This clean and in exhaustible energy can cover the heating demand of the office space. Our project consists of the integration of a solar thermal system controlled and controlled by a solar controller that will ensure optimal use of the solar heating system. Office heating is provided by low temperature radiators. Given its geographical location, Algeria lends itself favorably to solar applications. The global solar radiation varies between 1700 and 2650 kWh / m2 / year, for a duration of sunshine which is close to 3500 hours/year [1,2]. It is with this in mind that our project is to take advantage of this energy to cover the heating needs in the building. A solar collection field is installed on the terrace, the heated water is stored in a solar tank, which supplies the radiators for the heat distribution in the building. The building housing offices located in Bouzareah, Algiers (36°47’24” north, 3°01’04” east). The climate is warm and temperate.
