STRUVIA™ Phosphorus Recovery and Harvesting System

Struvia™ Phosphorus Recovery and Harvesting technology developed by Veolia facilitates the recovery and the reuse of phosphorus contained in wastewater.

Struvia™ Phosphorus Recovery and Harvesting technology developed by Veolia facilitates the recovery and the reuse of phosphorus contained in wastewater.

Phosphorous is an essential compound of life. There is no known substitute for phosphorous and it is bound to become a valuable resource in the near future. Veolia developed the Struvia™ technology to recover phosphates & ammonia from concentrated wastewater through crystallization / precipitation process.

Struvite is a nuisance at many wastewater treatment facilities. Struvite, or Magnesium Ammonium Phosphate (MAP), will precipitate out of solution once it exceeds the solutions supersaturation threshold in the wastewater. Struvite will deposit in pipes, tanks, and various other mechanical equipment resulting in costly down-times for maintenance.

The Struvia™ Phosphorus Recovery and Harvesting technology will solve the struvite problem while harvesting valuable nutrients from the wastewater stream. These nutrients (phosphorous and ammonia (N)) can be used for fertilizers, agriculture, and for animal feed.

Struvia™ Phosphorus Recovery and Harvesting uses a patented mixer, TurboMix™, in combination with lamella settlers to produce and separate struvite crystals from the wastewater within a single reactor with a small footprint, making it an economical phosphorous recovery process. Struvia™ is compact, resource-efficient, and produces a granular end product consisting of magnesium ammonium phosphate (MAP) crystals.

Struvia™ Phosphorus Recovery and Harvesting system proactively removes phosphorus from nutrient-rich sidestreams. This low-energy process thus saves on operating costs by reducing struvite-related maintenance. Struvia™ also reduces the amount of coagulant used for chemical P removal in the mainstream treatment process. Struvia™ does all of this while producing a valuable, high-demand end product that is rich in recycled nutrients.
