The invention converts toxic brines created during the desalination of brackish ground water and acid mine drainage into fertilizers.
Treating brackish ground water has presented an expensive problem to recover up until the advent of the KNEW process (Potassium Nitrate ex Waste). Water is neutralized through an ion exchange battery to remove all the dissolved ions leaving a water of any required quality. The ions are then converted into profitable fertilizers. The KNEW process is currently the most profitable and environmentally desalination process. 2103 IchemE award winner.
