Measurement of radon exhalation rate and radiation doses in fly ash samples.

Coal based thermal power plants contribute about ~ 72% of the power generation in India. Indian coal is of bituminous type, having a high ash content with 55-60% ash. Due to considerable environmental importance the collected fly ash has become a subject of worldwide interest in recent years.

Data on treatment of sewage wastewater by electrocoagulation using punched aluminum electrode and characterization of generated sludge.

The electrocoagulation setup must be optimized in order to design an economically feasible process. Therefore, in this work, the effect of the punched aluminum electrode on the performance of the electrocoagulation (EC) has been investigated. A series of experiments were performed for treatment of sewage wastewater using plane electrode and compare with punched electrodes.

Assessment of groundwater quality by water quality indices for irrigation and drinking in South West Delhi, India.

Groundwater quality should be continuously monitored for irrigation and drinking purpose so that risk from geochemical contaminants can be reduced by appropriate treatment method. Therefore, the focus of the present study was to determine the suitability of groundwater collected from South West Delhi, India, for irrigation and drinking purpose on the basis of various water quality indices. In order to assess the groundwater quality, 50 samples were collected from different sites of selected study area and parameters such as pH, EC (electrical conductivity), total dissolved solids (TDS), salinity, total hardness (TH), total alkalinity (HCO), calcium (Ca), magnesium (Mg), sodium (Na), potassium (K), chloride (Cl), Fluoride (F), sulfates (SO) and Nitrates (NO) were determined.

Assessment and hydro-geochemical characterization for evaluation of corrosion and scaling potential of groundwater in South West Delhi, India.

In the present study, hydro-geochemical characteristics of groundwater samples collected from South West Delhi, India, have been assessed. 50 sampling locations were recorded with the help of global positioning system, to assess the groundwater quality and evaluate the corrosion and scaling potential. Hydro-geochemical characterization for different parameters such as pH, temperature (T), electrical conductivity (EC), total dissolved solids (TDS), salinity (SA), total hardness (TH), total alkalinity ( ), levels of anions such as calcium (Ca), magnesium (Mg), sodium (Na), potassium (K) and cations which include chloride (Cl), Flouride (F), sulfates ( ), Nitrates ( ) was done using standard APHA methods.
