Achieving drinking water compliance levels for metaldehyde with an acclimated sand bioreactor
Metaldehyde removal was delivered to below the 0.1 µg L-1 regulatory concentration in a laboratory scale continuous upflow fluidised sand bioreactor that had undergone acclimation through selective enrichment for metaldehyde ... -
From full-scale biofilters to bioreactors: engineering biological metaldehyde removal
Rolph, Catherine A.; Jefferson, Bruce; Brookes, Adam; Choya, Andoni; Iceton, Gregg; Hassard, Francis; Villa, R. (Article)Polar, low molecular weight pesticides such as metaldehyde are challenging and costly to remove from drinking water using conventional treatment methods. Although biological treatments can be effective at treating ... -
Impacts of microalgae pre-treatments for improved anaerobic digestion: Thermal treatment, thermal hydrolysis, ultrasound and enzymatic hydrolysis
Villa, R.; Ometto, Francesco; Quiroga, Gerardo; Psenicka, Pavel; Whitton, rachel; Jefferson, Bruce (Article)Anaerobic digestion (AD) of microalgae is primarily inhibited by the chemical composition of their cell walls containing biopolymers able to resist bacterial degradation. Adoption of pre-treatments such as thermal, thermal ... -
Influence of light regime on the performance of an immobilised microalgae reactor for wastewater nutrient removal
Whitton, Rachel; Ometto, Francesco; Pidou, Marc; Jefferson, Bruce; Villa, R. (Article)Microalgae immobilised within a resin shaped into beads have demonstrated the ability to remediate nutrients from wastewater effluents within hydraulic retention times as low as 3 h. Methods to further optimise performance ...
