Bioflocculation of Euglena gracilis via direct application of fungal filaments: a rapid harvesting method
Funding Information: Special thanks to the US Agricultural Research Service for the provision of fungal strains. Thanks also to Dr Marilyn Wiebe (Technical Research Centre of Finland) for her expert advice on fungi and Johanna Oja for her technical help. This research was enabled by funding from The Land and Water Technology Foundation, The Finnish Cultural Foundation, and The Finnish Foundation for Technology Promotion. Publisher Copyright: © 2021, The Author(s). The high cost and environmental impact of traditional microalgal harvesting methods limit commercialization of microalgal biomass. Fungal bioflocculation of microalgae is a promising low-cost, eco-friendly method but the range of …
Particle balance and return loops for microplastics in a tertiary-level wastewater treatment plant.
Highlights: Dewatering by centrifugation was a step that removed a high number of MPs from the sludge. Sludge retained especially the fibrous microplactics. Reject water transported microplastics inside a wastewater treatment plant. Disc filter-based tertiary treatment ensured removal of 99% of microplastics in wastewater. Microplastics (MPs) from households, stormwater, and various industries are transported to wastewater treatment plants (WWTPs), where a high proportion of them are captured before discharging their residuals to watersheds. Although recent studies have indicated that the removed MPs are mainly retained in wastewater sludge, sludge treatment processes have gained less atten…

Microplastics (MPs) from households, stormwaters and various industries are transported to wastewater treatment plants (WWTPs) where a high proportion of them are captured before discharging their residuals to watersheds. Although recent studies have indicated that the removed MPs are mainly retained in wastewater sludge, sludge treatment processes have gained less attention in MP research compared to water streams at primary, secondary and tertiary treatments. In this study, we sampled twelve different phases in a tertiary-level municipal WWTP in Central Finland. Our results showed that compared to plant influent load, three times higher number of MPs was circulating via reject water from …
