Student Projects

Abstract

Plastics are accumulating in the natural environment due to their longevity and can have negative eects. Waste water treatment plants might act as a potential source of micro plastic particles into the environment. No standard methodology exists to quantify micro plastic particles in the euents of waste water treatment plants. In this study a methodology to sample, extract, identify and quantify micro plastic particles in the euents of waste water treatment plants has been developed. The study showed that additional treatment step of ltration after the secondary clarier can lower the amount of micro plastic particles released by waste water treatment plants.

Microplastics

Microplastics are fragments of any type of plastic less than in length, according to the U.S. National Oceanic and Atmospheric Administration (NOAA) and the European Chemicals Agency. They cause pollution by entering natural ecosystems from a variety of sources, including cosmetics, clothing, food packaging, and industrial processes. The term macroplastics is used to differentiate microplastics from larger plastic waste, such as plastic bottles or bigger pieces of plastics. Two classifications of microplastics are currently recognized.

Plastic pollution

Plastic pollution is the accumulation of plastic objects and particles (e.g. plastic bottles, bags and microbeads) in the Earth's environment that adversely affects humans, wildlife and their habitat. Plastics that act as pollutants are categorized by size into micro-, meso-, or macro debris. Plastics are inexpensive and durable, making them very adaptable for different uses; as a result, manufacturers choose to use plastic over other materials.

Industrial wastewater treatment

Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater that can be treated in sewage treatment plants.
