As specialized reed bed consultant, Sievertconsult did the design for the Design & Build contract for the water management of the Sustainable Pavilion from Dubai at the World-Expo 2020. This water management concept won the MEP Middle East Award 2020, Project of the Year.
The system consists of 4 treatment units: Condensate treatment, the treatment of brackish ground water for fresh water production (Well & RO-unit) and the separate treatment of grey water (Ultrafiltration) for direct reuse and the toilet water (black-water) from the building is treated with a settling tank, mechanical self-cleaning filter, vertical flow reed bed in the landscaping and an aeration tank (basement) and a final Ultrafiltration (MBR). As space was limited in the project, the reed bed filtration was combined with a membrane filtration to reach the desired quality of TSE for reuse on a limited area. The combination of a reed bed with a MBR reduces the disadvantages and enhances the advantages of both technologies: Reed Bed area is reduced to minimum (Reed Beds are used only for filtration and organic load reduction).
