Factors affecting the remediation of wastewater worldwide through eco-technologies

Water has always been an essential resource for the survival of living systems and a crucial reserve for the development of human society and the economy. However, current water resources are being contaminated by environmental factors, which include social systems, climate change, as well as industrial and agricultural waste. Water pollution has become a worldwide concern because of the increasing level of water demand. This global issue is a challenging spot to filter wastewater before enters into reservoirs of water. In this regard, it is necessary to identify the level of pollution, the form in which it already exists, and the biological efficacy of the water to establish sustainable techniques and scientific methods for removing pollution. Several eco-technologies of water remediation such as constructed wetlands, ecoremediation, green bridges, and green lake technologies are conferred and worked out widely. This chapter deals with water-associated contaminants and remediation factors with eco-friendly remediation developments including natural and advanced procedures. The advanced environment-friendly technologies with new methods and improved materials need to encounter the demand for wastewater treatment management. The improvement of both environmental and human health is the ultimate goal of wastewater management.
