The Consequences Of Environmental Pollution

The environmental pollution is a global issue now a days. It is a huge challenge to ensure a pollution free environment. Environmental pollution is any release of pollutants into water, land, or air which may cause severe impairments to the global ecological balance or that decrease the quality of life. The consequences of environmental pollution is a massive damage in the delicate balance of the biological food web that are visible only over long time phases [1-3]. Until relatively recently in humanity's history, where pollution has existed, it has been predominantly a native problem. The introduction of motorized vehicles, enormous industrialization of the society and the explosion of the human population, however, have instigated an exponential…show more content…
Pure water is an animating fluid while polluted water is a real curse for livings being [14]. It is very important to manage this resource, not only as a social, industrial and commercial good but also for the sustainable benefit of all present and future living matter. Water pollution is the introduction into fresh or ocean waters of chemical, physical, or biological material that degrades the quality of the water and affects the organisms living in it. This process ranges from simple addition of dissolved or suspended solids to discharge of the most insidious and persistent toxic pollutants (such as pesticides, heavy metals, and non-degradable, bio-accumulative, chemical compounds) [15]. The textile dyeing industry consumes enormous quantities of water and also significant amount of dyestuff and chemicals. Generally there are several types of wet processing stages, fabric production profiles and hence fluctuations in effluent flow rates and compositions involved [16, 17]. Wastewater released by the textile dyeing industry pose a serious threat to the environment and the wastewater from this industry is well known to contain strong color, residues of dyes and chemicals, very high biological oxygen demand (BOD5), chemical oxygen demand (COD) and broad range of pH…show more content…
The electrochemical treatment is a relatively new eco-friendly technique providing certain advantages such as almost complete decolorisation of wastewater, operation under moderate pH range, low final temperature, significant COD, BOD5 and TOC reduction, no sludge formation and potential cost effectiveness. Moreover these techniques show facility and precision on control of the electrochemical process (since the electron is the main reagent) and a compact design [33]. Therefore, the feasibility of electrochemical oxidation of organic substrates in textile wastewater is attracted much attention since pioneering studies to the present days [34, 35]. The feasibility of electrochemical degradation of textile dyes have studied by several researchers using various electrode materials such as dimensionally stable anode (DSA) [36], platinum electrodes [31], diamond and metal alloy electrodes [37] and boron doped diamond electrodes [38,
