This chapter advances SDGs 6 & 7 by presenting membrane technologies that can be used to purify wastewater and produce biomass for energy.

This chapter advances SDGs 6 & 7 by discussing how to convert gelatinous industry wastewater into useful chemicals and fuels.

This chapter advances SDGs 6 & 7 by critically examining the recent developments, opportunities, market possibilities, and barriers in resource recovery in wastewater treatment plants.

Pesticides have the potential to contaminate groundwater resources and have become a serious concern worldwide. In this chapter, we have discussed the mechanism of pesticide pollution along with its trajectory from the land surface into aquifers. Additionally, the harmful effects of pesticides on human health and promising remedies for reducing pesticide pollution have also been discussed.

This chapter highlights important implications of the field such as permissible limits of heavy metals in water systems, major sources of aquatic heavy metal pollution, impact of heavy metal contamination on aquatic life, human health and environment, loss of resources in form of heavy metals, prominent strategies adopted to tackle the problem, recent advancement in treatment technologies for heavy metal contaminated wastewater, and future aspects.

This chapter examines how PPCPs are often termed as micropollutants or trace organics, as these compounds are present in the µg/L range in the environment. PPCPs may pose a serious threat to aquatic life, having acute and chronic toxicity responses. As a result, there is a need for evolving technologies to detect, identify, and remediate compounds from these micropollutants.

This book chapter advances SDGs 6 and 11 by providing information on various sources of pollution and ways to monitor them. Assuring water quality and purity is extremely important because water is an essential material for human survival.

This book chapter advances SDGs 6, 7 and 11 by discussing how we can create integrated ecological technologies that transform natural resources into anthropocentric goods and services, while restoring the land and reducing pollution by returning beneficial materials or energy to the ecosystem.

This chapter advances SDG 6 and SDG 13 by highlighting the connection between climate change and water resources. It describes some of the most sinificant efforts taken to mitigate climate change.

This book chapteradvances SDG 6 by focusing on the environmental impacts of the recovery of resources from industrial wastewater from different aspects such as water resources, aquatic life protection, greenhouse gas reduction, sustainable agriculture, human health, and environmental economics. Finally, the contribution of the recovery of resources in circular bioeconomy is discussed.
