- Sewage collection and water distribution networks
Kelechukwu Uche, 2018. Optimizing suspended solids removal during chemical treatment of humic and low turbidity water: Purification of peat extraction runoff water
The main objective of this thesis was to evaluate practical solutions for the optimisation of processes i.e. coagulation
and flocculation, in order to improve the efficiency and reliability of the chemical treatment of the typically humic
and low turbidity waters discharging from peat extraction site.
Joni Ruottinen, 2018. Impact of concrete type on the leaching of calcium hydroxide during flushing of water distribution network pipes (Finnish)
In this thesis, the suitability of different methods for reducing leaching from concrete lined pipes was investigated. The influence of concrete type and flushing water quality on the leaching of alkaline compounds and consequently on water pH was investigated via leaching experiment under laboratory conditions.
Felipe Campos Lopez, 2018 - valuating the effectivity of peat as sorbent material for mining water purification in pilot scale systems
The main objective of this thesis was to evaluate the suitability of using peat as a sorbent for the purification of mine process and drainage waters in pilot-scale purification systems.
Satu Kuusiola, 2017. Fate and effects of sewage derived estrogens on aquatic ecosystems
The main objective of this thesis was to investigate the occurrence, concentration, fate and estimated environmental impacts of the synthetic estrogen 17-a-ethinylestradiol (EE2) and the natural estrogens 17-b-estradiol (E2) and estrone (E1). Research methods included literature review and a case study where FATEMOD modelling software.
