Overcoming 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 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 کاملEcology of Metarhizium anisopliae in soilless potting media and the rhizosphere: implications for pest management
Wholesale container-grown ornamentals are often maintained at the nursery for at least two growing seasons and are subject to infestation by black vine weevil (BVW), Otiorhynchus sulcatus F., for several months each year. Therefore, a potting media amendment aimed at controlling BVW needs to persist for an extended period of time. These studies were conducted to determine the persistence and ec...
متن کاملReleasing phosphorus from calcium for struvite fertilizer production from anaerobically digested dairy effluent.
Being a non-renewable resource and a source of potential water pollution, phosphorus could be recovered from animal manure in the form of struvite (MgNH4PO4.6H2O) to be used as a slow-release fertilizer. It was found recently that the majority of phosphorus in anaerobically digested dairy effluent is tied up in a fine suspended calcium-phosphate solid, thus becoming unavailable for struvite for...
متن کاملNative Plant Production in Potting Media Amended with Anaerobic Digested Cattle Biosolids
Anaerobically digested cattle biosolids are a by-product of cattle waste processing for pollution control and biogas production, yet this material has potential as an economical component of potting mixes used for sustainable nursery container production. As an animal waste, this material could have valuable fertilizer properties that could reduce the amount of supplemental fertilizer applied t...
