Problems, Challenges, and Removing Methods of Micro Plastics from Water
Summary
This review examines the presence of microplastics in drinking water — both tap and bottled — and the technologies available to remove them. Microplastics have been detected in drinking water worldwide, and while conventional treatment removes some particles, smaller nanoplastics largely pass through. The authors assess filtration, coagulation, and advanced treatment options for improving microplastic removal in drinking water systems.
Abstract: Over the past few years, several studies have reported the presence of micro plastics in treated tap and bottled water, raising questions and concerns about the impact that micro plastics in drinking-water might have on human health. Microplastics are ubiquitous within the environment and are detected in marine water, wastewater, water, food, air and drinking-water, both bottled and water. Microplastics enter freshwater environments in a number of ways: primarily from surface run-off and both treated and untreated wastewater effluent, but also from combined sewer overflows, industrial effluent degraded plastic waste and atmospheric deposition. Further, the limited evidence indicates that some microplastics found in drinking-water may come from treatment and distribution systems for water and/or bottling of drinking water.
