Case study: Pilot treatment of olive mill and metal processing wastewater by ceramic membrane ultrafiltration
This paper presents the results of the pilot-testing performed at both locations during the months of June and October 2015, respectively.

The aim of this study was to compare an evaporation and oxidation as a final stage of stillage treatment to recycle the treated water and use it in the ethanol process, namely the fermentation process.
Oslo Airport Gardermoen (OSL) is situated over a ground water reservoir, and collection and handling of spent de-icing fluids is therefore of major importance.
The paper presents typical design data for nitrification and denitrification in MBBRs, plus results from guarantee tests where a single train is operated at design load, as well as results from normal operation of the plants.
Out of six plants with nitrogen removal in Norway, four plants use the Moving Bed Biofilm Reactor (MBBR) process.
The results from Norwegian and North American pilot and small full scale technology assessment studies.
Full-scale testing demonstrated that the combined denitrification MBBR process can easily remove 90 % of total N at reasonable operating costs.
The new CFIC® process was tested in parallel with the well-documented MBBR process.
Proof-of-concept has been demonstrated for a process that will utilize nutrients from sludge liquor, natural light, and CO2 from biogas to grow microalgae at wastewater treatment plants.
The feasibility of growing microalgae in natural light using wastewater high in nutrients (N & P) for the production of more bioenergy was examined.
