Are alternative magnesium sources the key for a viable downstream transfer of s...
Rodrigues, Denis Manuel; Fragoso, Rita do Amaral; Carvalho, Ana Paula; Hein, Thomas; Brito, António GuerreiroPhosphorus (P) recovery in source-separated decentralised wastewater treatment processes is an eco-efficient strategy in accordance with a circular economy perspective. Struvite (MgNH4PO4.6H2O) capture allows a reduction of P discharged to surface waters and generates a product known for its slow-release fertiliser properties. However, the cost and availability of current commercial Mg2+ sources hinder the down...
Combined pretreatment by ultrasound and struvite precipitation of raw substrate...
Coura, Renata D'arc; Rodrigues, Ana Cristina; Alonso, Joaquim Mamede; Ferraz, Ana Isabel; Brito, Luis Miguel; Abrantes, João C. C.The present study aimed to optimize the struvite chemical precipitation process in nitrogenrich anaerobic co-digestion systems. Struvite precipitation experiments were carried out using a mixture of cattle slurry liquid fraction and sewage sludge, with and without ultrasound pretreatment. Marine salt or MgCl2 were used as magnesium source in NH4 + :Mg2+ stoichiometric proportions of 1:1.5 and 1:3. Under the tes...
Microbial fuel cell-induced production of fungal laccase to degrade the anthraq...
Simões, Marta Filipa Jesus Freitas; Maiorano, Alfredo Eduardo; Santos, Jonas Gomes dos; Peixoto, L.; Souza, Rodrigo Fernando Brambilla deThe anthraquinone dye Remazol Brilliant Blue R is largely used in the textile industry. However, its removal from wastewaters is costly and complex. Many methods have been tested to solve this ecological problem, but there is still a need for efficient methods. We propose here an alternative use of a two-chambered microbial fuel cell (MFC), fuelled with domestic wastewater in the anodic chamber, to degrade a si...
