Clay Minerals and Metal Oxides Based Green Nanocomposites for Sustainable Water Remediation: A Review

Priyanka Pareek and Lalita Ledwani

Abstract

The textile, paper, and plastics industries are facing the challenges of water scarcity for dyeing, processing, and washing. A large volume of colored and heavy metal-based wastewater results from its operations. Water recycling and reuse are practical options for improving water availability while reducing environmental impacts from discharging untreated colored wastewater. Several methods are used to recycle chemical-rich wastewater: biological, chemical, and physical. Physical treatment of wastewater is the most favorable method over chemical and biological treatment because of its low cost, simple, and effective operating system, which offers different methods such as adsorption, filtration, sedimentation, distillation, etc. This review article is based on the physical method and uses various natural and low-cost adsorbents and green nanocomposites to remove dyes and heavy metals. However, several key concepts discussed here reveal the better method, including the green method, nanocomposites, water quality enhancement, low environmental impacts, and technology integration. Including this, environmentally friendly, inexpensive, natural, and achievable water conservation and treatment strategies are also discussed, highlighting the current limitations and opportunities for treating wastewater with sustainable and cost-effective methods.
