Use of recycled nutrients in biological wastewater treatment
(2017)
In this master’s thesis, possibilities for using recycled nutrients in industrial wastewater treatment, as nutrient source, were studied. Possible sources for recycled nutrients found, were biogas plant’s reject water, ...
Gamified participatory sensing: Impact of gamification on public’s motivation in a lake monitoring application
(2017)
Participatory sensing is the concept or practice whereby individuals or publics using ICTs such as mobile phones, contribute to data collection, analysis and sharing of knowledge. The lack of motivation from publics is ...
Synthesis and application of lignin-based adsorbents for metal cations removal from water solutions
(2017)
This research is focused on the development of a novel inexpensive and environmentally friendly nanocomposite materials that will act as adsorbents for the removal of Ni(II), Cd(II) and Pb(II) from aqueous solutions. In ...

Pulsed corona discharge and membrane filtration for purification of lettuce washing waters
(2016)
Washing processes constitute most of the water used in fresh-cut industry. Pulsed corona discharge (PCD) as an advanced oxidation process and membrane filtration were studied as possible treatment methods for lettuce washing ...
Mittaussuureiden hyödyntäminen pumppujen kuluman ja tukkeuman havaitsemisessa
(2017)
Keskipakopumppu on teollisuuden käytetyin pumpputyyppi ja sitä käytetään siirtämään erilaisia nesteitä pisteestä A pisteeseen B. Pumpattava neste sisältää usein paljon kiinteitä hiukkasia mikä aiheuttaa pumpun voimakasta ...
Waste water purification based on natural ice crystallisation
(2017)
In this thesis, a test system for the breaking and harvesting of ice grown from water is
developed using a systematic methodology. The purpose of this system is to form a part of
a larger system to purify waste water by ...
Enzymatic Synthesis, Recovery, and Purification of Ethyl β-ᴅ-glucopyranoside
(2015)
A method to synthesize ethyl β-ᴅ-glucopyranoside (BEG) was searched. Feasibility of different ion exchange resins was examined to purify the product from the synthetic binary solution of BEG and glucose. The target was to ...
