Progress in Multi-Soil-Layering Systems for Wastewater Treatment
Summary
Not relevant to microplastics — this review summarizes advances in multi-soil-layering (MSL) systems for decentralized wastewater treatment in rural areas, covering hydraulic performance and integration with other technologies, without addressing microplastic removal.
The use of decentralized wastewater treatment technologies is a reasonable solution for rural areas. As a decentralized treatment technology, the multi-soil-layering (MSL) system has recently drawn an increasing amount of attention owing to its merits, such as a high hydraulic load rate, small land area occupation, low probability of clogging, low investment, and low operation cost. This review summarizes the progress in MSL systems in the past decade, focusing on the directions of efforts for system optimization, the latest applications of MSL systems to various wastewater treatments, and the integration of MSL with other technologies. The great application potential of MSL systems is illustrated, and future research directions regarding better application of MSL systems are provided.

A Review of Strategies and Technologies for Sustainable Decentralized Wastewater Treatment
This review examines decentralized wastewater treatment as a sustainable alternative to large centralized systems, covering technologies suitable for both urban and rural settings. Researchers evaluated various treatment approaches including constructed wetlands, membrane bioreactors, and nature-based solutions for their ability to remove contaminants including microplastics. The study highlights how decentralized systems can improve water management while addressing emerging pollutant concerns.
Microplastic removal and management strategies for wastewater treatment plants
This review examines how well different wastewater treatment technologies remove microplastics and what management strategies can improve performance. While conventional treatment plants can remove a large percentage of microplastics from water, the particles often end up concentrated in sewage sludge that gets applied to farmland. The study highlights the need for advanced treatment options and better management of biosolids to prevent microplastics from simply being transferred from water to soil.
Mitigation of emerging pollutants and pathogens in decentralized wastewater treatment processes: A review
This review assessed the performance of decentralized wastewater treatment technologies — including constructed wetlands, biofilters, and solar disinfection — for removing emerging pollutants such as microplastics, pharmaceuticals, and pathogens, identifying combinations of processes that achieve the best overall removal.
[Microplastics in wastewater treatment: current status and future trends].
This review summarizes current research on microplastic occurrence, removal, and fate in wastewater treatment plants, noting that while plants capture most microplastics in activated sludge, significant numbers still escape into effluent. The sludge itself then becomes a major pathway for microplastics to enter agricultural soils when applied as fertilizer. Future treatment improvements and sludge management policies are needed to reduce these release pathways.
Distribution and removal mechanism of microplastics in urban wastewater plants systems via different processes
Researchers compared the microplastic removal efficiency of three wastewater treatment technologies and found that the anaerobic-anoxic-oxic process achieved the highest removal rate at 83.9%. Most microplastics were transferred to sludge during primary and secondary treatment stages, with dehydrated sludge containing significant concentrations. The study highlights that while wastewater treatment plants effectively intercept most microplastics, they also redistribute contamination to sludge, which may become a secondary pollution source.
