چکیده
The manufacture of mineral N fertilisers by the Haber–Bosch process is highly energy-consuming. nutrient recovery technologies from wastes through low-cost processes will improve sustainability agricultural systems. This work aimed to assess suitability gas-permeable membrane (GPM) technology recover an anaerobic digestate and test agronomic behaviour ammonium sulphate solution (ASS) obtained. About 62% total ammonia nitrogen removed using GPM was recovered, producing ASS with 14,889 ± 2324 mg L?1, which more than six-fold higher in digestate. evaluated a pot experiment triticale as plant for 34 days growth chamber. Compared fertilised Hoagland (Hoag), provided significantly biomass production (+29% dry matter), uptake (+22%), efficiency 3.80 compared 1.81 DM mg?1N Hoag, fertiliser replacement value 133%. These increases can be due biostimulant effect organic compounds assessed FT-Raman spectroscopy. considered bio-based effect.

Characterizing the Performance of Gas-Permeable Membranes as an Ammonia Recovery Strategy from Anaerobically Digested Dairy Manure
Capturing ammonia from anaerobically digested manure could simultaneously decrease the adverse effects of ammonia inhibition on biogas production, reduce reactive nitrogen (N) loss to the environment, and produce mineral N fertilizer as a by-product. In this study, gas permeable membranes (GPM) were used to capture ammonia from dairy manure and digestate by the diffusion of gaseous ammonia acro...
متن کاملRecovery of ammonia from swine manure using gas-permeable membranes: effect of aeration.
The gas-permeable membrane process can recover ammonia from manure, reducing pollution whilst converting ammonia into an ammonium salt fertilizer. The process involves manure pH control to increase ammonium (NH4(+)) recovery rate that is normally carried out using an alkali. In this study a new strategy to avoid the use of alkali was tested applying low-rate aeration and nitrification inhibitio...
متن کاملRecovery of ammonia from swine manure using gas-permeable membranes: effect of waste strength and pH.
Nitrogen recovery from swine manure was investigated using gas-permeable membranes. The process involved a continuous recirculation of an acidic solution through a gas-permeable membrane submerged in manure. Ammonia from manure was concentrated in the acidic solution increasing its pH, while pH decreased in manure. In the first set of experiments, nitrogen recovery efficiency was evaluated with...
متن کاملAmmonia removal from anaerobically digested dairy manure by struvite precipitation
Ammonia is one of the most important contaminants impairing the quality of water resources. When this is considered along with the fact that the global demand for nitrogenous fertilizers is in constant rise, the need for recovery as well as removal of nitrogen is well justified. Crystallization of N and P in the form of struvite (MgNH4PO4 6H2O), which is a slow releasing and valuable fertilizer...
