Assessment of water quality using principal component analysis: A case study of the river Ganges

Abstract: In present study multivariate statistical approaches are used; interpretation of large and complex data matrix obtained during a monitoring of the river Ganges in Varanasi. 16 physicochemical and bacteriological variables have been analyzed in water samples collected every three months for two years from six sampling sites where river affected by man made and seasonal influences. The dataset was treated using Principal Component Analysis (PCA) to extract the parameters that are most important in assessing variation in water quality. Four Principal Factor were identified as responsible for the data structure explaining 90% of the total variance of the dataset, in which nutrient factor (39.2%), sewage and feacal contamination (29.3%), physicochemical sources of variability (6.2%) and waste water pollution from industrial and organic load (5.8%) that represents total variance of water quality in the Ganges River. The present study suggests that PCA techniques are useful tools for identification of important surface water quality parameters.

The use of redox potential in water treatment processes

Abstract: The use of redox potential as a control parameter of wastewater treatment processes for characterizing the natural water condition and estimating the antioxidant properties of drinking water has been investigated.

Water quality assessment of the River Kabul at Peshawar, Pakistan: Industrial and urban wastewater impacts

Abstract: Untreated wastewater discharges may have significant short term and long term effects on the quality of a river system. Present study was undertaken to assess the present status of the water quality of the River Kabul near Peshawar in Pakistan. Seven sites were sampled upstream and downstream in the River Kabul in 2009. Samples were also taken from waste water channel (Budni Drain) that carries waste-water of Peshawar Industrial Estate as well as the domestic sewers to assess the pollution contribution of these sources to the River Kabul. Physico-chemical and microbiological parameters of the samples were analyzed during the study, as well as possible sources of contamination were investigated. The study showed that the pollution level in river is rising from upstream (at city entrance) to downstream (at city exit) due to discharge of domestic waste water effluents, agricultural activities, and solid waste dumping directly into the river.

Reactive Red 120 dye removal from aqueous solution by adsorption on nano-alumina

Abstract: The adsorption of Reactive Red 120 dye from aqueous solutions by using nano-alumina has been investigated. The batch adsorption studies were carried out to determine the impact of pH, contact time, concentration of dye, and the adsorbent dose on adsorption process. The maximum adsorption efficiency was observed at pH 3. However with an increase of the adsorbent dose, the dye removal efficiency increased, while the amount of dye adsorbed per unit mass (mg/g) decreased. A pseudo-second-order model best described the adsorption kinetics of the specified dye onto nano-alumina. In this case the Langmuir isotherm model appeared to be most suitable. Findings of the present study reveal that nano-alumina can be an effective adsorbent for the removal of Reactive Red 120 from aqueous solutions.

Photometric determination of ammonium nitrogen with the nessler reagent in drinking water after its chlorination

Abstract: The photometric procedure for determining ammonium nitrogen in the drinking water containing inorganic chloramines has been refined. The preliminary reduction of chloramines at pH 4–9 was performed by using sodium sulfite at the fixed concentration in the interval 0.1–0.2 mM. Thereafter the mixture of solutions K2HgI4 (1–2 mM) and NaOH (80–100 mM) was added and the optical density of the resultant colored solution was measured at 440 and 600 nm.
