As main disadvantage, if higher quality is required, treating grey water in a decentralized way is performed mostly in small technical installations such as Membrane-Bio-Reactors (MBR), which lead to high energy consumption, high operation costs and that need regular maintenance from experts. Additionally, reusing treated grey water for bathing or showering could rise the question of risk for human health and social acceptance, thus a risk assessment for greywater reuse would be necessary. \n\nIn two INTERREG-project (EmiS\u00fbre and CoMinGreat), researchers from the Chair for Urban Water Management developed and tested specific Constructed wetlands (a nature-based, vertical flow system with selected plants) as an additional treatment step (after conventional treatment) for Micropollutant elimination from municipal wastewater. Removal rates for Micropollutants as well as 'classical' wastewater pollutants (BOD, COD, NH4, P) and germs were excellent. One of the reasons for the very high removal rates is the addition of 15 % active substrate (Activated Biocoal \u2013 produced from plants) to the classical substrate (sand).\n\nThe main idea of the project is to develop and test a modular-designed system for greywater treatment from households \u2013 based on Constructed wetlands with the special substrate, as a decentralised solution for the utilisation of treated greywater in sustainable buildings. A pilot plant will be located in Lyc\u00e9e Edward Steichen of Clervaux for the duration of 15 months. The project is funded from the Administration de la gestion de l\u2019eau (Minist\u00e8re de l'Environnement, du Climat et du D\u00e9veloppement durable) particularly interested in saving potable water in line with the scope of the European Commission\u2019s Circular Economy Action Plan as the Luxembourg government\u2019s strategy on Circular Economy.","rp_start_date":"2022-10-01 14:49:16","rp_duration":24,"rp_main_funder":"Administration de la gestion de l\u2019eau ","rp_other_funders":[],"rp_external_partners":["Administration de la gestion de l\u2019eau "],"rp_keywords":["Greywater","Water reuse","Membrane-bio-Reactors","Constructed wetlands","Micropollutant elimincation","Wastewater","Sustainable buildings","AGE","Circular Economy"],"rp_members":[{"id":"50001938","isExternal":false,"isPI":true,"name":"Joachim Hansen","featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwMDE5MzhfX0pvYWNoaW0gSEFOU0VO","detailsPageUrl":"https:\/\/www.uni.lu\/fstm-en\/blog\/people\/joachim-hansen\/"},{"id":"50026211","isExternal":false,"isPI":false,"name":"Dr. Silvia Venditti","featuredImageUrl":"https:\/\/www.uni.lu\/en\/person-image\/NTAwMjYyMTFfX1NpbHZpYSBWRU5ESVRUSQ==","detailsPageUrl":"https:\/\/www.uni.lu\/fstm-en\/blog\/people\/silvia-venditti\/"}]},"research-project-status":[276],"research-project-type":[272],"field-of-interest":[287],"organisation":[53,47,29],"authorship":[131,106],"acf":[],"_links":{"self":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches\/10124"}],"collection":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches"}],"about":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/types\/core-researches"}],"author":[{"embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/users\/131"}],"version-history":[{"count":2,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches\/10124\/revisions"}],"predecessor-version":[{"id":25079,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/core-researches\/10124\/revisions\/25079"}],"wp:authorship":[{"embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/users\/131"},{"embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/users\/106"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/media\/10123"}],"wp:attachment":[{"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/media?parent=10124"}],"wp:term":[{"taxonomy":"research-project-status","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/research-project-status?post=10124"},{"taxonomy":"research-project-type","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/research-project-type?post=10124"},{"taxonomy":"field-of-interest","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/field-of-interest?post=10124"},{"taxonomy":"organisation","embeddable":true,"href":"https:\/\/www.uni.lu\/fstm-en\/wp-json\/wp\/v2\/organisation?post=10124"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
