The City of Paso Robles Wastewater Treatment plant simultaneously installed Title 22 tertiary treatment technologies and a phosphorus nutrient harvest system to provide a new source of sustainable water and address struvite build-up. The results of these system implementations will benefit agencies facing reduced plant inflows and struvite production.

Learning Objectives:

Have a basic understanding of a Title 22 Recycled Water production facility and treatment, permitting and testing obstacles to overcome.
List strategies to manage struvite formation and describe ways to look for signs of formation before it happens.
Demonstrate understanding of phosphorus harvesting principles and in which conditions a phosphorus harvesting system is effective.
