چکیده
The application of new technologies in the agro-industrial sector is needed to close loop nutrient cycle food chain. aim this work study feasibility combination two recovery technologies. In a first step, novel gas-permeable membrane technology recovers N from wastewater as an ammonium sulfate solution (a bio-based fertilizer). Secondly, electrodialytic process P, electrolyte solution, which P can then be precipitated struvite slow-release was tested different livestock wastewaters: swine manure (SM) and anaerobically digested SM (digestate). Recovery efficiencies for were 53% 94% digestate; 100% 74% digestate, respectively. results showed great potential combining these wastewaters, promoting sustainability realm bioeconomy.

متن کاملRecovery and concentration of polyphenols from olive mill wastewaters by integrated membrane system.
The purpose of this work was to analyse the potentialities of an integrated membrane system for the recovery, purification and concentration of polyphenols from olive mill wastewater (OMW). The proposed system included some well-known membrane operations such as microfiltration (MF) and nanofiltration (NF), as well as others not yet investigated for this specific application, such as osmotic di...
متن کاملA Novel Electrodialysis Membrane, Modified by Polydopamine and Carbon Nanofibers, Removes Toxic Heavy Metal Ions from Wastewaters
Background: In light of severe and growing shortages of clean water and the rising environmental pollution in many countries, seawater desalination has been an effective method to produce freshwater. Cationic membranes have enabled environmental scientists to effectively remove toxic heavy metals from wastewater and to regenerate freshwater. Methods: We used a novel method, involving electro- ...
متن کاملApplication of Struvite Process for Nutrient Recovery from Anaerobic Digesters of Livestock Wastewater
Process of struvite (MgNH4PO4·6H2O) precipitation is a promising method for phosphorus recycling. The use of cheap magnesium ore for precipitation struvite as phosphate recovery has been examined. The optimal conditions for precipitation are pH 9.0 and Mg: 4 NH : 4 PO molar ratio 1.1:30.7:1. Linear correlation of experimental data is in qualitative agreement with modelling calculation. Surf...
متن کاملMaximizing recovery of energy and nutrients from urban wastewaters
Historically, UWWs (urban wastewaters) that contain high levels of organic carbon, N (nitrogen), and P (phosphorous) have been considered an environmental burden and have been treated at the expense of significant energy input. With the advent of new pollution abatement technologies, UWWs are now being regarded as a renewable resource from which, useful chemicals and energy could be harvested. ...
