Phosphorus removal and recovery from sludge stream in water resource recovery facilities provides multiple benefits including phosphorus recovery, digester and pipes protection, and improvement of sludge dewaterability. This study discusses an innovative integrated system for achieving enhanced phosphorus recovery and sludge dewaterability optimization through brushtie and struvite precipitation.

Learner Outcomes:

The effects of orthophosphate on dewaterability of solids.
How to prevent operational and maintenance issues with Struvite precipitation.
The benefits of pre-digestion and post-phosphorus removal.
