A new greywater biological treatment technology was trailed and demonstrated for the first time: Greywater from baths/showers in the guest rooms is separately collected and transferred to settling tanks. After preliminary sedimentation the greywater is treated continuously in a six-stage Rotating Biological Contactor (RBC) system.

Initially, the purposes were to increase the state of the knowledge using MBR in wastewater treatment and evaluate a pilot-scale MNR during start-up and steady state conditions, in respect of nutrient and organic compounds removal and overall system performance. A second objective was to evaluate the performance of the MBR during different stress conditions (power failure, high loading rate and high flux) in respect of nutrient and organic compounds removal and overall system performance. A third objective was to investigate permeate quality with respect of nutrients and organic compounds after infiltration through soil columns. The purpose was to assess if the effluent quality was suitable for direct discharge into the underlying groundwater or surface water.
