Struvite formation, control and recovery

Water Research, 2002
Recent 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, 2002
Formation 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 ...

A review of struvite crystallization for nutrient source recovery from wastewater

Journal of Environmental Management, 2023
Nutrient 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 ...

Assesing the Potential for Struvite Recovery at Sewage Treatment Works

Environmental Technology (United Kingdom), 2001
Struvite in wastewater treatment plants was identified as early as 1939. Problems with struvite formation date back to the 1960s when it was noticed at the Hyperion treatment plant, Los Angeles. Operators at the plant noticed crystalline deposits on the underside of post digestion screens.

Phosphorus recovery from wastewater by struvite crystallization: Property of aggregates

Journal of Environmental Sciences, 2014
Struvite crystallization is a promising method to remove and recover phosphorus from wastewater to ease both the scarcity of phosphorus rock resources and water eutrophication worldwide. To date, although various kinds of reactor systems have been developed, supporting methods are required to control the struvite fines flushing out of the reactors.

Co-Precipitation of Cd with Struvite During Phosphorus Recovery

Chemosphere, 2023
During 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 ...

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 ...

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 ...
