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 ...
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 ...
Investigating high-power ultrasonic vibration and vacuum as methods to enhance the extraction of water from municipal wastewater sludge
(2016)
The main objective of this thesis is to uncover and investigate physical mechanisms that can be used to develop efficient ways to remove water from municipal wastewater sludge. The essential criterion will be to minimize ...
Development of novel hybrid adsorbents for recovery of rare earth elements from mining effluents
(2017)
The main objective of the thesis was to develop novel hybrid adsorbents for the recovery of rare earth elements (REEs) from acidic mine waters. Three different groups of adsorbents, based on different combinations of ...
