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

    Master-uppsats, Lunds universitet/Industriell elektroteknik och automation

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

    Sammanfattning : 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. LÄS MER

  2. 2. The fate of pebbles and planetesimals entering protoplanetary envelopes

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Emil Zadera; [2019]
    Nyckelord :Planet formation; planet; protoplanet; protoplanetary envelope; protoplanetary atmosphere; protoplanetary growth; planetary growth model; accretion rate; vapour blob; vapourblob; vapour planet; transport of water; water on planet; pebbles; planetesimals; pebble accretion; planetesimal accretion; meteors; ablation; fragmentation; sublimation; protoplanetary disk; MMSN; accretion window; accretion channel; accretion; destruction; disruption; terminal velocity; gas; gasflow; shearingbox; exoplanet; Physics and Astronomy;

    Sammanfattning : Planetary embryos grow by the accretion of solid dust-material, ranging from cm- to m-sized pebbles up to km-sized planetesimals. However, the underlying size-distribution of the accreted material is poorly understood. LÄS MER

  3. 3. Modelling Chemically Enhanced Primary Settlers Treating Wastewater using Particle Settling Velocity Distribution : Modellering av kemfällning i försedimentering för avloppsvatten, genom att använda distribuering av sedimentationshastigheter för suspenderadepartiklar.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Emma Lundin; [2014]
    Nyckelord :Modelling; Primary clarifier; Chemically enhanced clarification; Settling velocity; MATLAB Simulink; Total suspended solids; Wastewater; Resource recovery;

    Sammanfattning : The urban sprawl creates a gap between producers and consumers and the a sustainable circuitof nutrients and energy is difficult to maintain. Many times the waste that is created in urbanareas is not reused and the circuit is lost. LÄS MER
