  1. 1. Biokinetic Characterization of Methane Oxidizing Microbiomes Co-metabolizing Trace Organic Chemicals

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Hugo Möller; [2024]
    Keywords : Methanotrophs; organic micropollutants; co-metabolism; biodegradation; applied microbiology; Earth and Environmental Sciences;

    Abstract : The presence of organic micropollutants (OMPs) in wastewater effluents is concerning, as they pose a threat to human and aquatic health. Biodegradation via methane-oxidizing bacteria (MOB) is an attractive option, as the method is cheap and effective. MOB can co-metabolize a variety of substrates, there among organic micropollutants.

  2. 2. Wastewater Characterisation for Design and Modelling of Primary Settlers at Municipal Wastewater Treatment Plants

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Louise Westin; [2023]
    Keywords : Primary Settling Tank; Wastewater Treatment; Settleometer; Particle Settling Velocity Distribution; Modelling.; Technology and Engineering;

    Abstract : The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. READ MORE

  3. 3. Wetland restoration on Öland : a short-term evaluation of vascular plant community composition after topsoil removal and reinstated grazing

    University essay from SLU/Dept. of Ecology

    Author : Marta Holmlund; [2023]
    Keywords : wetland restoration; vegetation; biodiversity; topsoil removal; Ellenberg indicator values;

    Abstract : Wetlands are recognized as important types of ecosystems, inhabiting rich biodiversity and performing multiple ecosystem services. However, many have been lost because of anthropogenic activities and a majority of the remaining wetland habitats are in bad conditions, displaying both loss of functionality and biodiversity.

  4. 4. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Hana Faulds; [2023]
    Keywords : Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

    Abstract : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

  5. 5. House price and fertility behavior among different families - Empirical study from CFPS data

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Huichan Chen; [2023]
    Keywords : House Price; Fertility Rate; Gender Effect; Birth Plan Policy; One Child Policy;

    Abstract : This paper uses panel data from the China Family Panel Studies (CFPS) to examine the relationship between housing prices and fertility behavior in China, this paper analyzes sample data from 2014, 2016 and 2018 and uses Probit model and the logit model to study how house price affects fertility behavior among different families, furthermore, after the removal of One Child Policy, how the fertility behavior would react to house price. The study found that rising housing prices have a significant negative impact on fertility behavior, and that this negative impact persists even when using instrumental variables to control for endogeneity.
