Struvite control through process and facility design as well as operation strategy

Abstract

Struvite deposition is a common problem in municipal wastewater treatment plants and can be significant if not anticipated, but struvite deposits are completely manageable if properly addressed. This paper summarises experiences from a number of facilities that have dealt successfully with struvite problems, elaborates on the interrelations between secondary treatment and anaerobic digestion, and outlines an approach to control struvite and available alternatives.
