FORSKER, AQUATEAM COWI

Lelum begynte i Aquateam COWI i 2017. Før dette var han ansatt seks år i DOSCON og åtte måneder på Teknologisk Institutt. Han har syv års erfaring med avanserte renseteknikker i vann og avløpsvanns, modellering og optimalisering av koaguleringsprosesser, sanntidsmåling og kontroll av renseprosesser, virtuelle sensorer og validering av måleresultater, fjerning av tungmetaller med koagulering og omvendt osmose samt fjerning og gjenvinning av næringssalter.

Lelum har vært koordinerende sekretær for flere internasjonale forsknings- og utdanningsprosjekter. Han var medlem av to internasjonale konferanser: IWA Particle Separation (Oslo, 2016), IWA European Utility Management (Oslo, 2014) og anmelder for 4 internasjonale journaler inkludert IWA- Water Science and Technology  og IWA-Journal of Water Supply: Research and Technology – AQUA i 2015.
