Abstract

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.

Abstract (english)

Environment pollution with microplastics particles (MP) has recently gained attention as one of the largest ecological issues. Microplastics is toxic for the living world due to its biomobility, abioaccumulation, interaction with stable organic pollutants and easy permeation into living organisms via the food chain. Sources of microplastics in the environment can include improper waste disposal, waste waters from water treatment plants in industries where microplastics is produced and/or applied, as well as sewage and rainfall. For the purpose of reducing the emission of microplastics particles into the environment, it is necessary to completely remove microplastics from water treatment processes, before releasing it in into the receivers. Current research includes various physical-chemical processes for removing MP particles from all water treatment processes such as coagulation, flocculation, adsorption, membrane filtration and disinfection. This paper provides an overview of research done so far that increases the efficiency of removing microplastics from water treatment and wastewater treatment processes.
