A series of technologies have been employed in pilot-scale to process digestate, i.e. the byproduct remaining after anaerobic digestion agricultural and other wastes, with aim recovering nutrients reducing load solids organics from it, hence improving quality digestate for potential subsequent reuse. In this case originated a mixture dairy animal wastes small amount wastes. It was processed by application several treatments, applied series, microfiltration, ultrafiltration, reverse osmosis,...
Abstract A combination of membrane processes was applied to treat the digestate produced after anaerobic treatment pig manure in a biogas plant, aiming towards recovery nutrients and effective water for potential reuse. Initially, coarse filtration (sieving microfiltration) used remove particles larger than 1 µm, followed by ultrafiltration, reduce suspended solids concentrations below g/L. Subsequently, selective electrodialysis is employed recover main nutrient ions, primarily ammonium...
Ultrafiltration and reverse osmosis proved effective in treating the liquid fraction of anaerobically digested sewage sludge, both with without an intermediate selective electrodialysis treatment step. The incorporation significantly increased clean water recovery rates (from 38% to 88%) while concurrently reducing its dissolved solids load by almost two orders magnitude, from 869.0 10.3 mg/L. Selective efficiently separated ions into stable fractions that could be post-processed produce...
The reuse of nutrient-rich waste in order to create green fertilizers a sustainable and efficient way is new strategy for the transition circular economy. Digestate produced as by-product from anaerobic digestion plants large amounts creating major management issue both storage, utilization or disposal. current work focuses on development an innovative, small-scale technology processing digestate that use food, animal, agricultural sludge waste. targets recovery fibres nutrients production...
In recent decades, there has been a growing focus on the management and valorization of digestate, primarily driven by its nutrient-rich composition, which positions it as promising resource for biofertilizer production. However, several countries still restrict direct application digestate due to potential environmental hazard, includes presence contaminants emerging concern (CECs) such pharmaceuticals. This paper explores efficacy novel UV/ozone-based technology, UVOX Redox®, in removing...
