Struvite Formation, Control and Recovery
Water Research, 2002Recent legislation on the removal of nutrients from wastewater has led to a number of operation problems with struvite scaling. Struvite is MgNH4PO4 x 6H2O and this paper reviews the formation, control and recovery of struvite from primarily municipal wastewater and other waste streams.

Potential Phosphorus Recovery by Struvite Formation
Water Research, 2002Formation of struvite (MgNH4PO4 x 6H2O) at sewage treatment works can cause operational problems and decrease efficiency. Struvite has a commercial value and the controlled formation and recovery of it would be beneficial. A mass balance was conducted at full scale across the whole sewage treatment plant in order to identify a stream to conduct bench ...

Co-Precipitation of Cd with Struvite During Phosphorus Recovery
Chemosphere, 2023During the struvite recovery process, Cd, a hazardous metal commonly found in waste streams, can be sequestered by struvite. This study investigated the influence of Cd2+ on the precipitation of struvite. Quantitative X-ray diffraction (QXRD) results showed that the purity of struvite decreased from 99.1% to 73.6% as Cd concentration increased from 1 ...

A Review of Struvite Crystallization for Nutrient Source Recovery From Wastewater
Journal of Environmental Management, 2023Nutrient recovery from wastewater not only reduces the nutrient load on water resources but also alleviates the environmental problems in aquatic ecosystems, which is a solution to achieve a sustainable society. Besides, struvite crystallization technology is considered a potential nutrient recovery technology because the precipitate obtained can be ...

Looking Beyond Struvite for P-Recovery
Environmental Science & Technology, 2013) and could potentially be used asa slow-release fertilizer. If the economic and life cycle costs aretaken into account, however, it becomes clear that phosphaterecovery as struvite is likely not the best approach, for thefollowing reasons: (1) production of P-mineral with a highcontent of struvite from real wastewater is a difficult and costlyprocess ...

A Theoretical and Practical Evaluation of Struvite Control and Recovery
Water Environment Research, 2013ABSTRACT: Struvite accumulation is a costly problem in many water resource recovery facilities (WRRFs) that use anaerobic digestion, causing significant labor and equipment costs and potentially impacting facility performance and permit compliance. A comprehensive study was undertaken to evaluate possible solutions to struvite control at two similar ...

Phosphorus Recovery by Methods Beyond Struvite Precipitation
Water Environment Research, 2018Unintentional phosphate precipitation at water resource recovery facilities (WRRFs) causes operation and maintenance challenges. With global phosphorus (P) scarcity looming and receiving water eutrophication caused by excess discharges of P, intentional P recovery at WRRFs has been gaining traction. To date, struvite recovery as slow release fertilizer

Recovery of Struvite from Calf Manure
Environmental Technology, 1999A full-scale plant for the recovery of struvite from calf manure has been installed at a calf manure treatment facility at Putten (the Netherlands), and is in the final stages of testing. If successful, all 4 calf manure treatment facilities, with a combined annual volume of appr.
