Evaluation of Quality of Water Supply of Belgaum City – A Case Study
Abstract
Evaluation Of Quality Of Water Supply Of Belgaum City -A Case Study traverses dense industrial and population clusters, farms and fields through its long stretch of 30 km before it meanders into the Markandeya River. The main goal of this study was to characterize Bellary nala’s combined industrial and municipal wastewater in terms of physico-chemical parameters.
Nature has mechanisms for self-purification that eliminate contaminants from water, soil, air and the environment in general. Mechanisms of self-purification include primarily absorption, diffusion, chemical reactions, and biological processes. A major factor in the self-purification mechanisms of the environment is the speed of processes, which depends mainly on the volume of contaminants, their nature, the weather, and the general characteristics of the environment.
River sand is becoming a scarce commodity and has thus become an alternative for exploration to it. Plastics are common polluting materials that are non-biodegradable. These will affect the soil fertility.
Streams, which in many areas serve the basic needs of water, play a significant role in shaping the environmental and ecological balance of the region through which it flows. Despite all these versatile contributory roles, it is knowingly or unknowingly used as a dumping site for the disposal of municipal and industrial waste waters with the intention that streams will take care of these wastes.
Discharge of the effluent beyond the water bodies ‘ self-purification capacity would definitely pollute the water. If the situation continues for a long time, a freshwater stream may transform into a sewer, or in other words, a water surplus region may transform into a water scarce region.
Conclusion
Concrete produced by replacing natural sand with manufactured sand with the addition of 0.5 per cent of plastic fibers imparts higher compressive, flexural and split tensile strengths due to sharp edges and better M-sand particle interlocking and good bonding with other materials. The compressive strength of 100% replaced sand concrete produced with 0.5% plastic fibers is 10.38% more than the reference mix (0% replaced mix).
