Design and Operation of Moving Bed Biofilm Reactor Plants for Very Low Effluent Nitrogen and Phosphorus Concentrations
Out of six plants with nitrogen removal in Norway, four plants use the Moving Bed Biofilm Reactor (MBBR) process.
Rotating belt screens: An attractive alternative for primary treatment of municipal wastewater
The results from Norwegian and North American pilot and small full scale technology assessment studies.
Environmental Technology Verification of a Biofilm Process for High Efficiency Nitrogen Removal From Wastewater
Full-scale testing demonstrated that the combined denitrification MBBR process can easily remove 90 % of total N at reasonable operating costs.
Development of a compact, cost effective, and energy efficient biofilm reactor for wastewater treatment and effluent reuse
The new CFIC® process was tested in parallel with the well-documented MBBR process.
Microalgae Growth For Nutrient Recovery From Sludge Liquor and Production of Renewable Bioenergy
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.
Utilisation of wastewater nutrients for microalgae growth for anaerobic co-digestion
The feasibility of growing microalgae in natural light using wastewater high in nutrients (N & P) for the production of more bioenergy was examined.
Impact of selective size distribution of influent suspended solids on downstream biological processes
Three lab-scale sequencing batch reactors (SBRs) were investigated to remove nitrogen from wastewater containing different particulate organic contents based on suspended solids (SS).
Sustainable wastewater treatment with the innovative CFIC® biofilm reactor process
This new process has been tested for municipal wastewater.
Increasing the sludge energy potential of wastewater treatment plants by introducing fine mesh sieves for primary treatment
The objective of this study was to compare some basic characteristics of sludge from fine mesh sieves (sieve sludge) with sludge from primary clarifiers.
Anaerobic co-digestion of microalgae Chlorella sp. and waste activated sludge
The study investigated the growth characteristics of environmental algal strain, Chlorella, in the modified Zarrouk medium and its anaerobic co-digestion with waste activated sludge (WAS).
