Folding boxboard mill wastewater treatment plant performance and operation
(2019)
This thesis was done to evaluate the performance of a folding boxboard mill wastewater treatment plant. In the literature part the folding boxboard production process was introduced, and the different board mill wastewater ...
Elintarviketeollisuusjätevesien laadun parantaminen ja puhdistusmahdollisuudet
(2019)
Elintarviketeollisuuden ympäristökuormitus muodostuu vedenkäytön ohella pääosin energian käytöstä ja jätteistä. Koska vesi- ja ympäristövastuu korostuvat oleellisena osana nykyaikaista yritystoimintaa, yritysten on pyrittävä ...
Functionality of a novel pilot-scale freeze crystallizer in wastewater purification
(2019)
Freeze crystallization (FC) is an energy efficient purification process employed to get the high product purity. During FC solvent freezes out and left concentrate behind. This characteristic of freeze crystallization makes ...
Electrochemical water treatment and filtration of generated slurries
(2018)
This work is focused on the electrocoagulation (EC) as an electrochemical water treatment process followed by solid-liquid separation of the solid species, which form during the treatment. In the theory part of the thesis, ...
Selective recovery of indium from secondary resources by iminodiacetic acid chitosan
(2019)
Indium demand has escalated drastically in the last few decades, due to the technological advancement and the introduction of the high-tech products such as Liquid Display Panels and the mobile device; this demand is not ...
Sunlight-driven photocatalytic reduction of noble metals ions to nanopartices
(2019)
The investigation of the noble metal ions photoreduction to nanoparticles was conducted in this Master Thesis. Four types of graphitic carbon nitride powders were synthesized through the thermal polycondensation reaction ...
Bioelectrochemical remediation of oil-contaminated marine sediment via novel microbial electrochemical snorkel
(2021)
Following an unintentional oil spill, marine sediments serve as an ultimate sink for a variety of human-made organic pollutants, especially petroleum hydrocarbons. The activity of indigenous microfloral populations connected ...
Removal of pharmaceuticals from water using modified biochar
(2022)
The production of microalgae in wastewater is a sustainable method to obtain microalgal biomass because it biofixes carbon while remediating wastewater. The microalgae can then be pyrolyzed to produce valuable products ...
ATP-based monitoring system for CIP rinse waters in enzyme industry
(2020)
This thesis was made for Genencor International Oy enzyme plant in Jämsänkoski, Finland. The product packing lines are cleaned with cleaning in place (CIP) method and the cleaning verification is performed with a traditional ...
End-of-life membrane modification inside spiral-wound modules using layer-by-layer coating with polyelectrolytes
(2020)
Possibility for membrane modification of end-of-life reverse osmosis spiral-wound elements was investigated in this study. End-of-life membrane was successfully cleaned from the membrane fouling and converted to ultrafiltration ...
