A bilayer coarse-fine infiltration system minimizes bioclogging: the relevance of depth-dynamics
(Elsevier, 2019-06)
Article
Open AccessBioclogging is a main concern in infiltration systems as it may significantly shorten the service life of these low-technology water treatment methods. In porous media, biofilms grow to clog partially or totally the pore ... -
A mechanistic model (BCC-PSSICO) to predict changes in the hydraulic properties for bio-amended variably saturated soils
(2017-01)
Article
Open AccessThe accumulation of biofilms in porous media is likely to influence the overall hydraulic properties and, consequently, a sound understanding of the process is required for the proper design and management of many technological ... -
Bilayer infiltration system combines benefits from both coarse and fine sands promoting nutrient accumulation in sediments and increasing removal rates
(2018-04)
Article
Open AccessInfiltration systems are treatment technologies based on water percolation through porous media where biogeochemical processes take place. Grain size distribution (GSD) acts as a driver of these processes and their rates ... -
Connecting bacterial colonization to physical and biochemical changes in a sand box infiltration experiment
(Elsevier, 2014-09-19)
Article
Restricted access - publisher's policyInfiltration through sediments is linked to complex biogeochemical processes occurring at small spatial scales, often leading to a progressive reduction in infiltration rates due to microbial growth and/or mechanical ... -
Interaction between physical heterogeneity and microbial processes in subsurface sediments: a laboratory-scale column experiment
(2017-06)
Article
Open AccessPhysical heterogeneity determines interstitial fluxes in porous media. Nutrients and organic matter distribution in depth influence physicochemical and microbial processes occurring in subsurface. Columns 50 cm long were ... -
Linking biofilm spatial structure to real-time microscopic oxygen decay imaging
(2018-02)
Article
Open AccessTwo non-destructive techniques, confocal laser scanning microscopy (CLSM) and planar optode (VisiSens imaging), were combined to relate the fine-scale spatial structure of biofilm components to real-time images of oxygen ... -
The effects of sediment depth and oxygen concentration on the use of organic matter: an experimental study using an infiltration sediment tank
(2015-04-02)
Article
Open AccessWater flowing through hyporheic river sediments or artificial recharge facilities promotes the development of microbial communities with sediment depth. We performed an 83-day mesocosm infiltration experment, to study ...
