METHOD AND SYSTEM FOR THE CRYSTALLISATION OF STRUVITE FOR RECOVERING PHOSPHATES IN WASTEWATER |
摘要 |
The invention relates to a method and a system for struvite crystallization of in order to recover phosphates in urban or industrial wastewater preferably having phosphate concentrations higher than 50 mg P/L, more preferably higher than 100 mg P/L, where phosphates are recovered by means of the crystallization thereof in the form of struvite granules, the diameter of which can reach up to 5 mm. The struvite crystallization system is formed by a crystallizer (1), a decanter (2) with a distribution system (9), and a unit for adding industrial magnesium hydroxide (3). The phosphates are recovered from the wastewater as a result of two steps : a step of growing struvite granules, and a step of growing fine struvite crystals. |
