5. 4. INVESTIGATION OF PHOSPHORUS SORPTION BY SEDIMENT DERIVED BIOCHAR - A LITERATURE REVIEW

   University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

   Author : Christina Henricson; [2023]
   Keywords : ;

   Abstract : As excess phosphorus in water bodies causes eutrophication, biochar can be used as an adsorbent to remove phosphorus from water, thus increasing the circularity of phosphorus in the society. This literature review is a summary of recent research on optimised uptake of phosphorus by sediment derived biochar. READ MORE

6. 5. Unsupervised Anomaly Detection in Multivariate Time Series Using Variational Autoencoders
