Sažetak
Recently, new pollutants affecting water quality have been a cause of concern. Microplastics (MP), which are one of them, represent plastic particles smaller than 5 mm. These particles have been detected in water (freshwater and marine) systems, as well as in terrestrial ones. The impact of particles on aquatic organisms and human health is still not sufficiently understood. Accordingly, there are studies which are focus on the technologies and their effectiveness for MP removal from water. MP can be removed by physical, chemical, biological, and membrane processes. Membrane processes depend on membrane characteristics (material type, thickness, water sorption, porosity, pore size), and operating parameters (transmembrane pressure, water flux, specific energy consumption). The primary mechanism is size-exclusion, but in the presence of electrostatic interaction, pore adsorption can also occur, resulting in higher fouling phenomenon. Membrane processes account for 13 % of all the methods used to remove MP, of which 5 % is via membrane bioreactors [1]. Ultra filtration (UF), dynamic membrane technology, reverse osmosis, and membrane bioreactors (MBR), are frequently used for MP removal from water. According to the high efficiency (80.0 % – 99.9 %), membrane bioreactors are often used, and UF is often used in combination with other processes as the second stage of (waste)water treatment [2]. MP can be effectively removed from wastewater if advanced treatment process that combines membrane processes and biological treatment is applied: 99.9 % of amount-reduction was achieved by MBR, 97.0 % by rapid sand filter, 95.0 % by dissolved air flotation, and 40.0 – 98.0 % by disc filters [3].
