Microplastics Extraction and Counting from Wastewater and Sludge Through Elutriation and Hydrocyclone
AI summary Read the abstract
A combined elutriation and hydrocyclone method effectively separates and concentrates microplastics from wastewater and sludge, enabling more accurate counting of synthetic fibers and fragments. Improving extraction efficiency in wastewater treatment analysis is critical for quantifying how much microplastic escapes treatment plants and enters waterways.
Microplastics are defined as plastics whose size is smaller than 5 mm [1, 2]. According to Correira (2018), around 35% of the microplastics present in the ocean, correspond to fibres from synthetic textiles [3] detached from clothes in washing machines [4]....

Pretreatment Methods for Further Analysis of Microplastics in Wastewater and Sludge Samples
AI summary Read the abstract
Wastewater and sludge samples require careful pretreatment to remove organic matter and other interfering materials before microplastic analysis can yield accurate results, and the choice of pretreatment method significantly affects particle recovery and identification. Standardizing pretreatment protocols is critical because wastewater treatment plants are major pathways through which microplastics reach both aquatic environments and agricultural soils via sludge application.
