Recovery of nitrogen and phosphorous as struvite from swine waste biogas digester effluent.
OBJECTIVE To investigate the feasibility of nitrogen and phosphorus recovery from swine waste biogas digester effluent and the effects of pH and NH4+: Mg2+: PO4(3-) molar ratio on its precipitation. METHODS Precipitation experiments with swine waste biogas digester effluent were conducted at pH 7.5, 8.0, 8.5, and 9.0 together with NH4+: Mg2+: PO4(3-) molar ratios 1: 0.2: 0.08, 1: 1: 1, and 1:...
متن کاملStruvite recovery from swine waste biogas digester effluent through a stainless steel device under constant pH conditions.
OBJECTIVE To investigate the struvite precipitation under constant and non-constant pH conditions and to test a stainless steel device under different operating regimes to maximize the recovery of struvite. METHODS The molar ratio of NH4+: Mg2+: PO4(3-) was adjusted to 1: 1.2: 1.2 and pH was elevated to 9.0. The absorbance measurement was used to trace the process of struvite crystallization....
متن کاملComparison of Air Emissions from Raw Liquid Pig Manure and Biogas Digester Effluent Storages
Biogas digesters are commonly used in livestock farming in China. The digestion process converts large amounts of raw liquid manure (RLM) to biogas digester effluent (BDE). The BDE is then stored on the farm for some time before land application as crop or orchard nutrients. Storage of RLM or BDE is associated with gas emissions, although little information is available concerning comparison of...
متن کاملBiogas stripping of ammonia from fresh digestate from a food waste digester.
The efficiency of ammonia removal from fresh source-segregated domestic food waste digestate using biogas as a stripping agent was studied in batch experiments at 35, 55 and 70°C, at gas flow rates of 0.125 and 0.250Lbiogasmin(-1)L(-1)digestate with and without pH adjustment. Higher temperatures and alkaline conditions were required for effective ammonia removal, and at 35°C with or without pH ...
متن کاملReview on Biogas Production from Co- Digestion of Cow Dung and Foodwaste with Water Hyacinth
With Increasing Energy Demand in the World and to keep Environment Friendly, biogas technology has attained a notable position for the future scope. This paper tells about a comprehension review on anaerobic digestion of cow dung and food waste with Water hyacinths to enhance biogas productions. Water hyacinths are treated as waste in rivers, ponds, but they have high potential in biogas produc...
