Bhavani is one of the important rivers in Tamil Nadu. Many industries, particularly textile processing units, tanneries, sugar factories and distillery units, are situated on the banks of Bhavani river. These industries let out untreated and partially treated effluents into the river stream. It is, therefore, decided to study the quality of water and to estimate its pollutional load in the River Bhavani. Samples of water were collected at selected points and physcio-chemical and biological examinations were carried out. A simple, comprehensive water quality index system, devised by NSF of USA and an alternative method adopted, were applied and the water quality assessed at every point. It was observed that at the start of monsoon season the water quality in the Bhavani river was good, but showed a progressive decline from its origin to further distances as it passes through human settlements and industrial areas.Keywords

An attempt has been made to study the physico-chemical characteristics and biological investigations of Cauvery river at Erode region. The sampling points were selected on the basis of their importance. Industrial wastewater, dyeing effluents and sewage are allowed to mix with the Cauvery river water in this region. Water Quality Index (WQI) has been calculated based on National Sanitation Foundation (NSF) index system. Water Quality Index is an easy tool to assess the quality of surface waters and to control the pollutional load of water bodies.Keywords
Cauvery River, Water Quality Index, Pollutional Load, Feacal Coliforms.- Replacement of River Sand Using Manufactured Sand and Quarry Dust in Cement Concrete

River sand is widely used for concrete as fine aggregate. The increased cost of river sand and depletion in ground water table due to illegal sand mining leads to find an alternative for fine aggregate without compromising the strength. In this study, concrete mix M30 has been designed using quarry dust and manufactured sand by replacing the river sand. Four mix proportions were made to test the effect of inclusion of quarry dust and manufactured sand in concrete and the results were compared with the control specimens. It was found that the strength of the concrete is enhanced in both the types of replacements.Keywords

The sharp fall in underground water table in river basins is said to be the outcome of indiscriminate sand mining resulting in the deepening of river beds. The natural sand beds have voids of 45-50% in the soil where the rain water is retained by the river sand. This property of the river sand is mainly responsible for maintaining the ground water table in and around river basins. This paper deals with the partial replacement of river sand by fly ash in aggregate in concrete without compromising the strength.- Treatment of Wastewater from Dairy Industry by Root Zone Method

In India, the dairy industry contribute a significant percentage of the total quantity of waste generated. Since, milk processing consumes large amount of water, the volume of effluent discharged from the industry is very high. It increases level of BOD and depletes dissolved oxygen of the receiving waters. In this paper various water quality characteristics such as pH, electrical conductivity, COD and TDS of the effluent are studied before and after the application of ischolar_main zone treatment system (RZTS), and it is found that the treatment is very effective.- Study on Biodegradability of Vegetable and Flower Wastes by Vermicomposting

An experimental study was conducted to determine the efficiency of vermicomposting process of various types of organic wastes such as vegetable, fruit and flower wastes. Various characteristics like pH, electrical conductivity, moisture content, total solids, volatile solids and ash content were monitored continuously to ascertain the stability of the compost. The vermicomposting process for flower waste and fruit-vegetable waste mixture was compared. Both the processes were found to be effective with significant nutrient enrichment.- Reduction of Global Warming Gas Emissions from the Manufacture of Portland Cement Using High Volume Fly Ash Concrete

The Global warming gases are increasing steadily in the world due to the advent of industrialization. In 1800 before the industrial revolution started, the concentration of CO2 gas in the atmosphere was estimated to be 260 ppm only. The concentration of CO2 in the year 1988 was observed in Hawaii to be 350 ppm. The data indicate that the rate of concentration of global warming gases (GWG) in the atmosphere has increased considerably in the past few decades. This pushes the average global surface temperature by about 0.7°C. The United Nations Intergovernmental Panel on Climate Change (IPCC) has taken the view that average global temperature could rise by 1.4°C-5.8°C by the end of this century. This paper discusses some aspects of global warming and the role of admixtures in reducing emissions of CO2 to the atmosphere.- Water Quality Index of River Noyyal at Tirupur, Tamil Nadu, India
