| Abstract |
Multi-soil layering (MSL) is an efficient and eco-friendly soil-based system ingeniously engineered to circumvent common limitations imposed by soils when used as filtering materials for wastewater treatment. However, relatively few comprehensive and critical reviews emphasize the significant assets of successful application and durable operation and discuss the cutting-edge orientations to promote the acceptance and widespread use of this emerging Ecotechnology. To bridge the existing research gap, after giving the essential knowledge on the principle, typology, and treatment mechanisms of MSL reactors, the present paper reviews and criticizes current applications and discusses the most influencing factors to highlight their crucial role in maintaining sustainable design and effective operation. Furthermore, this paper provides guidance and discusses future scopes and novel perspectives to promote MSL systems' effectiveness, large-scale development, and sustainability by optimizing operational conditions and transitioning toward renewable energies and circular economy approaches. Further, the present paper gives an estimative evaluation of the capital cost of an MSL system based only on locally available materials. Lastly, this review summarizes the most relevant recommendations relative to sustainable design and operation in the form of holistic guidelines from emergence to recent state of art as a start-up and consultative base for stakeholders and researchers interested in MSL technology. |
