Phosphorus Recovery from Wastewater by Struvite Crystallization: A Review [PDF]
Critical Reviews in Environmental Science and Technology, 2009 The present review provides an understanding of principles of struvite crystallization and examines the techniques and processes experimented to date by researchers at laboratory, pilot, and full-scale to maximize phosphorus removal and reuse as struvite from wastewater effluents.

Phosphorus Recovery from Sewage Sludge as Struvite [PDF]
Water, 2023 Environmental legislation on waste management coupled with the potential for nutrient recovery are key factors encouraging the use of advanced treatment technologies to manage biosolids waste. In this context, phosphorus recovery from sewage sludge treated by a wet oxidation (WO) process was carried out in this work.

RECOVERY OF STRUVITE FROM STORED HUMAN URINE
Environmental Technology, 2008 In previous work, synthetic urine was used as a readily available proxy for real urine for determining the factors which affect the recovery of struvite from urine. Based on these findings with synthetic urine, we recovered struvite from real urine and, thus, showed that a) the synthetic urine served as an adequate model for determining the processes ...

Understanding struvite crystallisation and recovery [PDF]
, 2006 Struvite crystallisation from wastewater effluents is seen as an alternative to traditional biological and chemical phosphorus removal processes used widely in the wastewater treatment industry. It presents the advantage of not only removing phosphorus

Assessment of struvite and K-struvite recovery from digested manure [PDF]
, 2018 Human population has had an impact on the natural phosphorus’ cycle, a limited resource, and the predictions show that this resource could be exhausted in 100-250 years. Therefore, the actions for the coming 10-25 years must be focus on the recovery of phosphorus, for example, from renewable sources such as manure. Thus, phosphorus recovery as struvite

An economic evaluation of phosphorus recovery as struvite from digester supernatant
Bioresource Technology, 2006 Phosphorus can be recovered from wastewater through crystallisation of struvite, MgNH(4)PO(4).6H(2)O. Approximately 1 kg of struvite can be crystallised from 100 m(3) of wastewater. Crystallisation is profitable compared to chemical and biological removal of phosphorus due to savings from the reduction in (i) chemicals used for precipitation and sludge

Phosphorus recovery by struvite precipitation: a review of the impact of calcium on struvite quality [PDF]
Journal of Water, Sanitation and Hygiene for Development, 2021 Abstract Precipitation of phosphorus (P) as a struvite product from wastewater and local magnesium (Mg) sources is considered as a high economical prudent venture, as it has shown to bring down the cost of producing the product. However, there is a significant concentration of calcium (Ca) in these Mg and most wastewater sources.

Ammonia removal and recovery using heated struvite as an adsorbent
, 2011 The removal and recovery of aqueous ammonia from BNR plant centrate or supernatant is an important research area. Stringent ammonia discharge requirements must be met to avoid fish toxicity in the receiving waters. Completely removing ammonia from the process reduces the load recycled back to the head of the plant and minimizes operational problems ...

Biological recovery of phosphorus from waste activated sludge via alkaline fermentation and struvite biomineralization by Brevibacterium antiquum [PDF]
, 2022 Struvite biomineralization is a promising method for phosphorus recovery from wastewater treatment plant streams, and the growth of responsible microorganisms in mixed cultures is one of the most critical points for applying this process in pilot and ...

Process optimization of low-cost struvite recovery
, 2009 Struvite (MgNH4PO4·6H2O) recovery from wastewater streams has been known as an efficient nutrient recycling method. However, current research has predominantly addressed high-end solutions to overcome fertilizer shortages in agriculture and prevent eutrophication in receiving waters.
