Recovery of NH4 through QW-N

​

• The use of QW-N has been proven to provide exceptional recovery of NH4-rich streams into a receptor stream that NH4 is soluble in

​

• The conventional approach is to use an acid with the end result being an ammonium rich stream.

​

• Recovery results ranging from ~75% up to 99% have been confirmed in field evaluations through a variety of agricultural, municipal and industrial streams.

​

• Efforts have been undertaken to use a distilled water type solution as the receptor stream.

​

• Reduces consumable costs.

​

• Maintains desired nutrients in the treated stream for other applications such as irrigation.
