This invention relates to the prevention of struvite deposition at wastewater treatment plants with biological phosphorus removal. For this purpose calcium silicate hydrate (CSH) is dosed direct into the digestion tower. The CSH stays in suspension. This enables a long reaction time for CSH absorbing phosphate even if it is incipiently blocked.
