  • 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.

    Gizmag Emerging Technology Magazine

  • This unasked-for struvite clogs lines and valves, reduces flow rates, and has to be removed either mechanically, or by running acid through the lines.

  • This struvite, in turn, is processed into a nitrogen/phosphorus/magnesium slow-release fertilizer sold as Crystal Green.

    Gizmag Emerging Technology Magazine

  • 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.
