Microplastics and its removal in wastewater treatment processes
AI summary Read the abstract
This Croatian thesis reviews microplastic sources, distribution, and removal in wastewater treatment processes. The author examines the effectiveness of different treatment stages and discusses the environmental and biological toxicity concerns associated with microplastic pollution.
Onečišćenje okoliša česticama mikroplastike (MP) u posljednje vrijeme dobiva veliku pozornost kao jedan od najvećih ekoloških problema. Mikroplastika je toksična za živi svijet zbog svoje biopokretljivosti, abioakumulacije, interakcije s postojanim organskim onečišćivalima i laganog ulaska u žive organizme putem hranidbenog lanca. Izvori mikroplastike u okolišu mogu biti nepropisno odlaganje otpada, otpadne vode sa postrojenja za obradu voda u granama industrije gdje se mikroplastika proizvodi i/ili primjenjuje te komunalne i oborinske vode. U svrhu smanjivanja emisije čestica mikroplastike u okoliš potrebno je u procesima obrade voda potpuno ukloniti mikroplastiku prije ispuštanja u prijamike. Istraživanja koja se provode uključuju različite fizikalno-kemijske procese za uklanjanje čestica MP u svim procesima obrade voda poput koagulacije, flokulacije, adsorpcije, membranske filtracije i dezinfekcije. U ovom radu dan je pregled dosadašnjih istraživanja koji poboljšavaju učinkovitost uklanjanja mikroplastike u procesima pročišćavanja i obrade otpadnih voda.

Microplastics in wastewater treatment plants: Sources, properties, removal efficiency, removal mechanisms, and interactions with pollutants
AI summary Read the abstract
This review examines microplastic sources, properties, removal efficiency, and removal mechanisms across different wastewater treatment plant stages. Researchers found that while treatment plants remove a significant portion of microplastics, they cannot eliminate them entirely, resulting in the continued release of millions of particles into the environment daily through effluent and sludge.
Microplastics in Wastewater Treatment Plants: Characteristics, Occurrence and Removal Technologies
AI summary Read the abstract
This review summarizes how wastewater treatment plants are a major pathway for microplastics entering the environment, covering the types, sizes, and sources of microplastics found in wastewater. While treatment plants can remove many microplastics, significant amounts still escape into rivers and oceans through treated water and sludge. The authors evaluate various removal technologies and recommend advanced treatment methods to better prevent microplastics from reaching water supplies.
