Ostara’s Pearl system from Evoqua is a fluidized bed reactor designed to recover phosphorus from municipal and industrial waste streams through the controlled precipitation of crystalline struvite. The growth of struvite (magnesium ammonium phosphate) is facilitated by the addition of magnesium. This allows nutrients to crystallize into eco-friendly fertilizer granules which are harvested, dried and then distributed and sold by Ostara as Crystal Green Fertilizer. This cost-effective nutrient recovery solution converts wastewater treatment plants into resource recovery facilities. 800-466-7873; www.evoqua.com
