Wastewater Disposal Techniques

Each and every human activity which uses water generates wastewater; however as the overall demand for water rises, the quantity and quality of wastewater generated. The major challenge is to provide an increasingly growing global populace with plenty of freshwater with increasing demands for growth of more power, more nutrition, more enterprise, and more consumption. Whereas wastewater is a vital component of the water conservation process, water is all too frequently seen as more of a nuisance to be disposed of or a hazard to be overlooked after it is used. The consequences of the negligence are now clear. The specific effects, including aquatic habitat depletion and waterborne disease from polluted freshwater sources, have reaching consequences to the well-being of ecosystems and the livelihoods of peoples. Facing with the ever rising demand, wastewater is attaining a momentum as a safe alternative water source, shifting the wastewater management paradigm through “treatment and disposal” to “recycle, reuse, and resource conservation.” Thru this manner, wastewater is no more seen as some kind of problem that requires a solution, rather than as part of a solution to the problems that society and the world facing today. This chapter focuses on the new wastewater technology which has been used in the world for the treatment of wastewater. The wastewater treatment methods are evolving with the rapid technical and time shift. Scientists and researchers are busy seeking new sewage treatment methods which are simpler to install and less costly to use. This chapter discusses wastewater treatment current methods which can make the water be reused for various purposes.
