Also in Luxembourg the realisation of a local pilot plant is only possible due to cooperation with a local hospital.

Advanced wastewater treatment at the Centre Hospitalier Emile Mayrisch in Esch-sur Alzette

The pilot plant for the Centre de Recherche Public Henri Tudor is built at the Centre Hospitalier Emile Mayrisch in Esch-sur Alzette. It has about 640 hospital beds and about 1,700 employees. The pilot plant is built for isolated streams and thus treats up to 1 % of the total hospital effluent. The flow to the pilot plant is in average about 1-3 m3 per day. Due to the hydraulic capacity of the membranes the hydraulic loading of the pilot plant is limited to 0.125 m³/h. The PILLS pilot plant works in three steps: The first step is a biologic membrane filtration before it is then treated by reversed osmosis, UV irradiation and / or ozone. The clean water is discharged into a water body.
