In the obtaining process of the kaolin by wet way, the influence that the quality of the water inthe rheological properties of the suspensions of ceramic kaolin was evaluated, for which benefittests of kaolin were carried out, using the same raw material and water of different sources andquality. The rheological properties of the kaolin suspensions were measured in terms of electrolytedemand -DE-, thickening, the Methylene Blue Index -IAM- and the rate of deformation. Theparameters of water quality evaluated were pH, conductivity, acidity, alkalinity, total hardness andfree chlorine. It was found that when alkalinity, the acidity and conductivity of the water used toobtain kaolin increases, also does the DE of the suspensions, however, despite observing a diferentbehavior between materials obtained from washing with water with few ions content and materialsobtained from washing with water with some more ions content, no specific relationship wasfound for thickening.

Life could not be imagining without the presence of water on this earth. An ecosystem is very dependent on the quality of water. Regular water quality monitoring is very essential of a region. In the study area, no study has been yet done on the quality of drinking water and productivity level of Beas river near Arni University, Himachal Pradesh, India. The main aim of this study was to determine the water quality of three different sources of water like hand pump water, tap water, and Beas river water. For this, we have collected total twenty-six samples in the month of May 2018 and analysed for pH, TDS, EC, DO, alkalinity, phenolphthalein alkalinity, total hardness, calcium hardness, chloride, sulfate, phosphate, nitrate, carbonate, bicarbonate, E. coli, and productivity level by standard methods. The entire analysed parameters showed the lower level than the permissible guideline of the WHO except for the presence of E. coli and higher level of alkalinity. The productivity level of Beas river was indicating that trophic index belonged to the ultra-oligotrophic. From the findings, it might be concluded that hand pump water, tap water, and Beas river water was drinkable except the presence of E. coli and higher level of alkalinity in tap water and river water. However, in the case of the productivity level of Beas river was indicating the very low accumulation of dissolved nutrient salts, and a lower rate of algae growth as the productivity level belonged to the ultra-oligotrophic. Further extensive study on the water minerals and heavy metals level in all the water sources are required in this study area.

One of the processes that significantly determines the quality of water to consumers is the process of mixing water from different sources in the water mains. Put to the network two or more chemically and biologically stable waters may result in the formation of water that will be deprived of these features. This article presents the german guidelines for analysing water quality for mixing waters from different sources, in various proportions. Then performed an analysis of utility the mathematical models,including quality criteria, for use in network control. An IT tool has been developed to manage selected water quality processes using mathematical modeling. The basis for implementing the tool was a network model created in Epanet integrated with the Matlab.

AbstractAs the surface water in northern India is the main water resource for regional economic and also supply for drinking and irrigation purposes. However, deficiency of water quality leads to serious water pollution in the Pandoh river basin (PRB). Therefore, the main objective of the present study is to evaluate the quality of surface water. With this objective, surface water samples were collected from the PRB of northern India, and analyzed for pH, EC, turbidity, alkalinity, total dissolved solids, and total hardness. Moreover, geographical information system (GIS) tools were used to prepare the geology, drainage pattern, and location maps of the study region. Surface water quality observed from the PRB has an alkaline nature with a moderately hard type. Further studies are encouraged to better understand the water quality in northern India.

This paper shows the results obtained in field analysis performed at the Tamis River, starting from the settlement Jasa Tomic - border between Serbia and Romania to Pancevo - confluence of Tamis into the Danube. The Tamis is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pancevo. During the years the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamis River on every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamis is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamis River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further pollution decreasing of the river's water.

Malwa region of Punjab state, India has become the center of water borne diseases due to excessive use of pesticides, chemical fertilizers, heavy metals, industrial toxins that cause toxicity in water. The main contamination in ground water is by physico-chemical parameters and heavy metals i.e. pH, total dissolved solids, total alkalinity, total hardness, calcium, chlorides, fluorides, arsenic and lead. The contamination of ground water with heavy metals causes health hazards to humans and animals. Due to lack of adequate facilities and resources for the management and handling of waste, the ground water contamination has been increased. In the present study, assessment of ground water quality was carried out in the villages of Ferozepur district of Punjab state, India. With main emphasis on analyzing the groundwater parameters of Ferozepur district which are responsible for health hazard to humans and animals. Various groundwater samples were collected randomly from the villages of Ferozepur district and analyzed for pH, total dissolved solids, total alkalinity, total hardness, calcium, chlorides, fluorides, heavy metals (arsenic and lead) using standard procedures. The concentrations of calcium, chlorides, fluorides and pH were within the permissible limits, whereas, alkalinity and total hardness were observed beyond permissible limits in most of the water samples. Even among majority of the samples taken, the concentration of arsenic and lead was found within the permissible limits. Results showed that the ground water samples collected from depth ranging from 100 to 360 ft, recorded values within permissible limits for drinking purpose as prescribed by WHO. Further, ANOVA has been applied on analysis results to study the effect of pH on fluoride and chloride, depth on fluoride and chloride and depth on arsenic and lead. Also, to adjudge the overall quality of water in Ferozepur district, the water quality index (WQI) has been calculated on the basis of large number of physico-chemical characteristics of water. The water quality index of ground water in Ferozepur district has been calculated to be 107. The value is close to 100 so the quality of ground water in Ferozepur district can be categorized under 'Good Quality' water.
