The role of struvite crystals and the necrobiome in estimating the postmortem interval for forensic investigations in the UK
… Kingdom (UK). Research in the UK has highlighted struvite crystal precipitation as a potential preliminary method for estimating the postmortem interval (PMI). The aim of this research was to investigate the use of struvite crystals and the microbial communities that precipitate them in estimating …

Natural zeolitites in combination with struvite precipitation technology for the recovery of nutrients from agricultural wastewaters
… technology consists in the precipitation of struvite crystals for the recovery of both nitrogen (N) and phosphorous (P). But, even if these processes are starting to scale up at industrial levels, the unbalance between the struvite components in wastewaters, as Mg2+, NH4+ and PO43-, remains …

Microbial Dynamics and Mechanistic Insights into a Hydrogenotrophic Denitrifying Microbial Consortium
… through the precipitation of 13.5 mg/L of struvite crystals. The precipitates obtained were found to be generated through biologically controlled mineralization (BCM) enabled by the dissimilatory nitrate reduction to ammonium (DNRA) process. By understanding and manipulating specific …

Investigating pretreatment methods for struvite precipitation in liquid dairy manure
… wastewater treatment regulations. P recovery as struvite (MgNH4PO4·6H2O) is a promising technology because it can be used as a slow-release fertilizer. The objective of this study was to investigate different pretreatment methods to enhance struvite precipitation in dairy manure. Generally there …

Understanding the impacts of supersaturation and seed crystal loading on struvite precipitation kinetics and collection efficiency
… of full-scale phosphorus removal with struvite precipitation processes is increasing. Utilities are increasingly understanding the necessity for higher levels of nutrient removal due to the regulatory pressures and the up and coming stringent discharge limits. To subsidize some of the …
