Struvite Causes Reduced Sludge Dewaterability and Wastewater Treatment Plant Capacity

In wastewater treatment plants with biological phosphate elimination, high phosphate concentrations occur in the digester’s anaerobic environment.

As a result, struvite (or MAP: magnesium ammonium phosphate) builds up inside the pipes, pumps and process equipment, causing problems including:

• Reduced plant capacity due to decreased flow through the digester’s pipes
• Reduced dewatering efficiency due to increased water bounding effects in the sludge by high phosphate levels
• Increased phosphate loads in the return liquor, which leads to a less efficient phosphate-elimination process and causes crystallization problems in pipes and pumps
