Assessment of the water quality standard of Brahmani River in terms of physico chemical parameters

Abstract

newline Water is needed for survival. Every living process takes place in this form. It is newlineneeded for both human growth and the proper functioning of the planet eco-system. Global newlineculture, industrial development, urban growth, and population growth have resulted in newlinerapid depletion of water supplies. The standard surface of Brahmani River in and around newlineindustrial district, which is situated at an average height of 160.7 meters above mean sea newlinelevel, is evaluated and interpreted in this Ph.D. study titled quotAssessment of the Water newlineQuality Standard of Brahmani River in terms of Physico-chemical Parameters quot. The thesis newlineis divided into seven chapters. The first chapter deals with relationships between quality of newlinewater, and human health, and anthropogenic practices that influence the quality of water, newlinescope and objective of the present work. Chapter 2 presents the importance of rivers in newlineIndia and impact of population and industrial growth around the Brahmani river. Chapter 3 newlinedescribes the role of physical and chemical components in wastewater assessment. Chapter newline4 includes the physico-chemical factors and nine samples were taken on the first working newlineday of each month over the entire length of the river basin. Physico-chemical parameters newlinesuggest that the water content of the Brahmani River is well within tolerance limits; newlineaccording to the current analysis. Panposh recorded the maximum pH value 8.4 and newlineGomlai the minimum pH value 6.5 with an average temperature of 22oC to 35oC. The newlineminimum conductivity value 84 and#956; mho/cm is recorded at Tilga. In the present newlineinvestigation, it is seen that TDS value of most of the water samples are well within the newlinepermissible limit except at Jareikela. Chapter 5 deals with analysis of water quality of newlineBrahmani river based on the concentrations of heavy metals like As, Cd, Ni, Zn, Pb and Cr newlinewere within permissible limits of WHO and BIS. Chapter 6 calculates the water quality newlineindex(WQI) which is recorded within 35-56 at various stations. There is a need of newlinetreatment before consumption of water for drinking purpose as in some stations, the water newlinequality index is very near to the border line of being contaminated by organic as well as newlineinorganic matter. Chapter 7 deals with recent nanotechnology advances in water and newlinewastewater treatment, Langmuir and Freundlich models are mainly used for stating the rate newlineof adsorption data with a recorded removal rate of Nickel and Zinc metals of newlineapproximately 71%. Chapter 8 ends with a conclusion over the water quality and effects of newlinephysico-chemical parameters in Brahmani river and future work
