Comparison of Ozonation and Fungal Treatment for the Depuration of an Anaerobically Pretreated Mezcal Vinasse
In Mexico, the manufacturing of mezcal generates huge amounts of mezcal vinasses (MV), that cause a negative environmental impact. Although there is no specific information for mezcal vinasses, similar effluents have been treated by anaerobic digestion (AnD) usually complemented by oxidative chemical post-treatments such as ozonation. In the present work the post-treatment of anaerobically pret...
متن کاملBiochar from anaerobically digested sugarcane bagasse.
This study was designed to investigate the effect of anaerobic digestion on biochar produced from sugarcane bagasse. Sugarcane bagasse was anaerobically digested to produce methane. The digested residue and fresh bagasse was pyrolyzed separately into biochar at 600 degrees C in nitrogen environment. The digested bagasse biochar (DBC) and undigested bagasse biochar (BC) were characterized to det...
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...
متن کاملOvercoming challenges to struvite recovery from anaerobically digested dairy manure.
Recovering struvite from dairy manure has consistently posed problems for researchers. This study separated solids from anaerobically digested dairy manure using a filtration system. Filtrate was rich in free magnesium (160 to 423 mg/L), ammonium (320 to 1800 mg N/L) and orthophosphate (93 to 332 mg P/L). High concentrations of free calcium (128 to 361 mg/L) and alkalinity (3309 to 6567 mg/L as...
متن کاملPreparation of Gd2O3 Ultrafine Nanoparticles by Pulse Electrodeposition Followed by Heat-treatment Method
Gd2O3 nanoparticles were prepared by a two–step process; cathodic electrodeposition followed by heat-treatment method. First, Gd(OH)3 nanoparticles was galvanostatically deposited from nitrate bath on the steel substrate by pulse current (PC) mode. The deposition experiments was conducted at a typical on-time and off-time (ton=1ms and toff=1ms) for 60 min. The electrodeposited precursor was the...
