RECOVERING FERTILIZER FROM WASTEWATER

Wastewater is the most common byproduct generated at our company’s processing facilities, and our Rousselot facility in Gerona (Spain) is no exception. The wastewater from the Gerona plant is generated through processes that are specific to this location, and the wastewater produced has its own unique properties.

Having an abundance of ammonium and phosphate, Operations Manager Juan Antonio Burdalo and his team have implemented an innovative method to turn this difficult-to-treat wastewater into a sustainable resource for fertilizers. The process makes use of nutrients present in the wastewater, and the three parallel batch reactors can produce five tons of struvite (a slow release fertilizer) per day.

CLEAN WATER,

The discharged wastewater is in compliance with all environmental guidelines so it can be given back to nature.

A NATURAL PRODUCT,

Up to five metric tons of struvite, a slow-release fertilizer can be produced per day.

HELPING CROPS GROW.

Struvite is a sought after nutrient for agriculture, horticulture, and sport and lawn applications.

WE HAVE STRUCK ‘THREE’ BIRDS WITH ONE STONE. OUR EFFLUENT IS CLEANER; WE DELIVER ON THE ENVIRONMENTAL ASPECT, AND WE HAVE FOUND A WAY TO REGAIN SOME OF THE COSTS OF WASTEWATER TREATMENT.
