Abstract

Struvite is an insoluble mineral that is ubiquitous in the solids handling potion of wastewater treatment plants. It can adversely affect treatment plant operations by precipitating in pipes and pump impeller surfaces reducing flows. The primary purpose of this study was to determine the feasibility of using CO2 for struvite control and provide recommendations for implementation. The work presented in the report demonstrated the feasibility of using CO2 to prevent the formation of struvite in wastewater treatment plants. Published by WRF. 56 pages. Online PDF. (2018)
