By harvesting most of the phosphorus, a reactor is said to virtually eliminate struvite build-up, further lowering the plant's operating costs, and increasing its capacity.
-
While struvite is produced on purpose inside reactors, it also occurs naturally when phosphorus and nitrogen combine with magnesium in a wastewater treatment plant's sludge stream.
-
Magnesium is added within the reactor, creating a concrete-like substance known as struvite.
