In central India, the groundwater is hard and contaminated with F<sup>-</sup> and other elements above the permissible limits and found to be linked with prevalence of the fluorosis diseases. In this work, the groundwater quality Balod district, Chhattisgarh, India is investigated for assessment of water quality for drinking purposes. The concentration (n = 50) of F<sup>-</sup> was ranged from 1.5 - 14.0 mg/L with mean value of 3.9 ± 0.8 mg/L. The causes of prevalence of skeleton fluorosis in human of the studied area are described.展开更多

In this work, the combustion characteristics of sewage sludge and green algae are described. The calorific value (CV) of dried sewage sludge (n = 7) and green algae (n = 11) was ranged from 1800 to 6250 and 3700 to 6280 kcal/kg with mean value of 3999 ± 1347 and 4428 ± 547 kcal/kg, respectively. The effect of proximate variables and water quality parameters in the CV of sludge and algae are discussed.展开更多
