Toxicological evaluation of tannery industry waste water on Oreochromis mossambicus

  This paper investigates the impact of tannery industry wastewater on O. mossambicus. The histopathological changes observed in gills, liver, kidney and brain of the studied fish have demonstrated the quality status of industrial waste water. In the vital organs, the following marked changes were observed: filament cell proliferation, cellular infiltration, haemorrhage and epithelial lifting in gills,...

Removal of faecal bacteria and nutrients from domestic wastewater in a horizontal surface flow wetland vegetated with Echinochloa pyramidalis

  The aim of this study was to evaluate the removal of faecal bacteria and nutrients from domestic wastewater, in surface flow wetlands vegetated with Echinochloa pyramidalis. Horizontal surface flow (HSF) wetlands were fed with primarily treated domestic wastewater at organic loading rates varying from 20.74 to 27.15 g BOD/m2/day for two consecutive years. Water samples were collected at two weeks...

Fuel properties of loofah (Luffa cylindrica L.) biofuel blended with diesel

  Fuel properties of loofah oil and its ethyl ester blended with diesel were experimentally determined. Biodiesel blends (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) of loofah oil and its ethyl ester by volume with diesel was used. The fuel properties of the biodiesel blends were determined according to American Society for Testing and Materials (ASTM) standards. Pure Automotive Gas Oil (AGO) was used as a...

Correlation-regression model for physico-chemical quality of groundwater in the South Indian city of Gulbarga

  Groundwater is a major source of municipal and private water supply in Gulbarga city. Water samples were collected from spatially referenced bore wells located in various wards of the city. 150 bore well water samples were analyzed for electrical conductivity (EC), pH, total dissolved solids (TDS), total hardness (TH), Ca2+, Mg2+, Na+, K+, HCO3-, CO32- Clˉ, SO42-,NO3ˉ, F and Fe. All tests were...

Precise estimation of total solar radiation on tilted surface

  A new correction factor (CF) which depends upon the longitude and altitude of the location, has been used for the estimation of hourly and total solar radiation at different orientation and inclination for Delhi. The estimated values of hourly solar radiation have also been compared with 15 years measured data of Delhi to establish the accuracy of the results. The study reveals that hourly and total solar...
