Advanced Water Treatment Technologies for Mitigating Marine Pollution in Coastal Ecosystems
AI summary Read the abstract
This review, which pulled together over 125 studies on water treatment, found that advanced filtering technologies, like reverse osmosis and specialized membrane filters, can remove up to 99% of harmful pollutants from coastal waters, including heavy metals, microplastics, and pharmaceutical residues. This matters because these contaminants build up in seafood and drinking water sources, so better filtration technology could significantly reduce our exposure to substances linked to long-term health problems. Combining multiple treatment methods together worked best, suggesting a promising path forward for protecting both ocean health and public health.
Coastal marine ecosystems are currently under increasing threat from industrial waste, agricultural runoff, urban wastewater, and emerging pollutants. In particular, heavy metals, microplastics, pharmaceutical residues, and mercury and polyfluoroalkyl compounds have long-term negative impacts on marine biodiversity, water quality, and public health. In this context, it is crucial to evaluate the effectiveness of advanced water purification technologies and determine their applicability in coastal environments. The objective of this study was to comprehensively analyze the efficiency, limitations, environmental sustainability, and future prospects of various advanced water purification technologies. To this end, more than 125 survey-based studies, research articles, and technical reports published from 2015 to 2025 have been reviewed. Comparative analysis shows that reverse osmosis and nanofiltration technologies have demonstrated approximately 95 to 99 percent efficiency in removing heavy metals and emerging pollutants, while ultrafiltration has achieved 85 to 95 percent efficiency in removing microplastics, and advanced oxidation processes and photocatalysis have achieved 85 to 98 percent efficiency in removing complex organic pollutants. In addition, hybrid water purification systems have demonstrated the highest performance in removing multiple contaminants simultaneously and have also increased the potential for water reuse and resource recovery. The results of this research provide an important scientific basis for coastal marine pollution control, sustainable water management, and the development of future advanced water purification technologies.

This review of over 125 studies found that advanced water filtering methods, like reverse osmosis and specialized filters, can remove 85-99% of harmful pollutants from coastal waters, including heavy metals, microplastics, and pharmaceutical residues. This matters because these contaminants can build up in seafood and drinking water sources, potentially affecting human health over time, so having proven technologies to clean them up gives coastal communities real tools to protect both marine life and public health.
Drinking Water Contaminants and Advanced Purification Technologies: A Review of Conventional and Emerging Treatment Approaches
AI summary Read the abstract
This review pulls together existing research on removing harmful contaminants, like PFAS "forever chemicals," heavy metals and microplastics, from tap water. No single filtering method catches everything, but combining technologies (like activated carbon plus advanced filtration) can remove up to 95 to 97% of these pollutants. The takeaway: layered water treatment systems are key to protecting public health as contamination from industry and climate change worsens.
The Occurrence of Micropollutants in the Aquatic Environment and Technologies for Their Removal
AI summary Read the abstract
This review summarizes the growing problem of micropollutants in water, including microplastics, pharmaceuticals, and industrial chemicals, and evaluates advanced treatment methods to remove them. The research is important for human health because conventional water treatment plants cannot effectively filter out these contaminants, meaning people may be regularly exposed through tap water.
Review of Advanced Water Treatment for Removal of Nanoplastic Pollution
AI summary Read the abstract
This review evaluates drinking water treatment technologies for removing nanoplastics, finding that combined coagulation, flocculation, and filtration achieves up to 99.9% removal efficiency. As nanoplastics are detected in drinking water globally and cannot be degraded in the environment or human body, identifying effective removal processes is directly relevant to protecting public health.
A review of microplastic removal from water and wastewater by membrane technologies
AI summary Read the abstract
This review examines how membrane filtration technologies can remove microplastics from drinking water and wastewater. Researchers found that advanced membranes like nanofiltration, reverse osmosis, and membrane bioreactors are among the most effective methods for capturing microplastic particles that conventional treatment plants miss. The study compares membrane approaches with other removal methods and discusses the challenges of membrane fouling caused by microplastic accumulation.
