Short Biography

Nelly Brugerolle de Fraissinette currently works as a research engineer at the Institute of Interdisciplinary Research on Environment and Materials (IPREM) in Pau (FR). She is part of MANTA, a research Chair aiming at developing novel bio-sourced and bio-inspired materials from the sea. She previously worked at the Interdisciplinary Centre of Marine and Environmental Research (CIIMAR, Porto, PT) as a graduate research fellow, in the context of the European project NoMorFilm (Grant nº 634588) - http://www.nomorfilm.eu/'. For a year, she was responsible for the isolation of secondary metabolites from cyanobacteria with inhibition potential against pathogenic biofilm-forming bacteria.

Cyanobacteria blooms occur frequently in freshwaters around the world. Some can produce and release toxic compounds called cyanotoxins, which represent a danger to both the environment and human health. Microcystin-LR (MC-LR) is the most toxic variant reported all over the world. Conventional water treatment methods are expensive and require specialized personnel and equipment. Recently, a multi-soil-layering (MSL) system, a natural and low-cost technology, has been introduced as an attractive cost-effective, and environmentally friendly technology that is likely to be an alternative to conventional wastewater treatment methods. This study aims to evaluate, for the first time, the efficiency of MSL eco-technology to remove MC-LR on a laboratory scale using local materials. To this end, an MSL pilot plant was designed to treat distilled water contaminated with MC-LR. The pilot was composed of an alternation of permeable layers (pozzolan) and soil mixture layers (local sandy soil, sawdust, charcoal, and metallic iron on a dry weight ratio of 70, 10, 10, and 10%, respectively) arranged in a brick-layer-like pattern. MSL pilot was continuously fed with synthetic water containing distilled water contaminated with increasing concentrations of MC-LR (0.18–10 µg/L) at a hydraulic loading rate (HLR) of 200 L m−2 day−1. The early results showed MC-LR removal of above 99%. Based on these preliminary results, the multi-soil-layering eco-technology could be considered as a promising solution to treat water contaminated by MC-LR in order to produce quality water for irrigation or recreational activities.
