(2019)Tämän diplomityön tarkoituksena oli selvittää, kyetäänkö laserkäsittelyn avulla parantamaan biolietteen kuiva-ainepitoisuutta. Lisäksi tutkittiin suodatuksen tukiaineiden käyttöä lietteen suodatuksessa. Kirjallisuusosassa ... -
Biosorption and bioaccumulation of geosmin from recirculating aquaculture system : fate of geosmin in aquaculture water
(2023)Geosmin (GSM) is one of the most common off-flavor compounds found in aquaculture wastewater which is responsible for the odor-related problems in fish. The microalgae assisted water treatment unit is used in Recirculating ... -
Cake filtration of recycled cemented carbide powder
(2023)Cake filtration is one of the most common ways to separate solid and liquid phases from each other. In cake filtration, the solid material accumulates on top of the filter medium, forming a cake layer. The properties of ... -
Carbon capture integration to steam cracker furnaces : techno-economic evaluation
(2023)In olefin production, over 90 % of carbon dioxide emissions are related to steam cracking furnaces. Reducing these emissions is major step towards targeting carbon neutrality goals. Various alternatives are currently being ... -
Catalyst-free simultaneous esterification and transesterification of low-quality fats and oils to FAME under subcritical water conditions and their purification
(2020)There are many advantages to using bio- or renewable diesel but the downside is its economic limitations related to feedstock prices which may be the largest cost item in the production. Because of this, there is a constant ... -
Chemical recycling of magnetic tape
(2019)This work aimed to study a recycling path for magnetic tapes. Magnetic tapes at the time of writing have no recycling processes and end up in dump despite their massive volumes. In the literature review composition of ... -
Circular economy principles in modeling and production of the “hydraulic cylinder head” part
(2022)The purpose of this work is a comprehensive analysis of the course of processes in the technological cycle of production and use of titanium alloys, by-products and production waste, taking into account the principles of ... -
Circular economy principles in modelling and production of the “Cylinder” part machining
(2022)Machining a part by milling on modern CNC machines is one of the best ways to get surfaces with accurate dimensions and the part with high surface accuracy. This thesis examines the process of machining of a "Cylinder" ... -
CO2 capture from gases by using hollow-fiber membrane contactor
(2019)The aim of this thesis was to examine the efficiency of CO2 capture by means of hollow-fiber membranes using potassium glycinate as the absorbent. The literature part presents the background for the thesis, conventional ... -
Combined non-thermal plasma and catalytic oxidation of low concentration methane
(2023)This master´s thesis studies the effect of non-thermal plasma and the hybridized plasma-catalysis system on the methane abatement by using Dielectric Barrier Discharge (DBD) reactor. The catalysts in the hybridized ... -
Comparative analysis of process control charts in order to define most efficient sampling frequency
(2021)This thesis conducts various comparative analysis of control charts in order to define most efficient sampling frequency. Control charts analyzed through this work are tools used in process of quality monitoring invented ... -
