Thermal performance and microclimate test methods for flat-plate solar thermal collectors
2012
In this Master’s thesis testing methods, experimental setups and data evaluation procedures for flat-plate solar thermal collectors are presented. An official quasi-dynamic test method according to the EU standard EN 12975 for evaluating the collector’s thermal performance is described, and its applicability to an existing experimental setup is evaluated. The general practicality of this setup is also reviewed. Furthermore, a second experimental setup is designed to monitor the inside conditions, or microclimate, of a solar thermal collector, in order to assess the frequency of condensation occurrence inside the collector. This work’s results include that the existing thermal performance se…
Water resource recovery by means of microalgae cultivation in outdoor photobioreactors using the effluent from an anaerobic membrane bioreactor fed w…

[EN] With the aim of assessing the potential of microalgae cultivation for water resource recovery (WRR), the performance of three 0.55 m3 flat-plate photobioreactors (PBRs) was evaluated in terms of nutrient removal rate (NRR) and biomass production. The PBRs were operated outdoor (at ambient temperature and light intensity) using as growth media the nutrient-rich effluent from an AnMBR fed with pre-treated sewage. Solar irradiance was the most determining factor affecting NRR. Biomass productivity was significantly affected by temperatures below 20 °C. The maximum biomass productivity (52.3 mg VSS·L−1·d−1) and NRR (5.84 mg NH4-N·L−1·d−1 and 0.85 mg PO4-P·L−1·…
