Recovery of phosphate (PO4-P) as struvite (MgNH4PO4·6H2O) from dairy lagoon wastewater (DW) limits contamination surface water arising application DW to crop fields. Magnesium (Mg) addition during PO4-P recovery is used promote precipitation and suppress formation undesired mineral products. A pilot-scale aerated fluidized-bed reactor was treat for recovery. The effect Mg concentration (0–20 mM...

Abstract This study investigated the mechanism of lactose assimilation in Nannochloropsis oceanica for dairy-wastewater bioremediation and co-production valuable feed/food ingredients a circular dairy system (β-galactosidase omega-3 polyunsaturated fatty acids). Mixotrophic cultivation was found to be mandatory N. , with biomass production mixotrophic cultures reaching fourfold increase over th...
