NORTHWESTERN UNIVERSITY

Our mission is to increase opportunities for NU faculty and students in all domains touching on water, to catalyze and coordinate water research across NU, and to increase the visibility and impact of NU water research by solving current and emerging grand challenges in water systems sustainability, efficiency, and robustness... Beginning with stage one, our tour guide illustrated the usage of Polyaluminum chloride (PAC) on flocculation/coagulation within incoming water. In this step, the aggregates sink to the bottom of a sedimentation pond forming sludge, and the remaining 99% of pre-treated water is returned to the sedimentation area. Then in the second stage, the water is moved into a standing operational reservoir where certain fishes are used to remove impurities and nuisances that bloom in the reservoir (i.e., particles, plankton, snails, algae, etc.). In stage three, the water is placed in the center filtration plant where another round of coagulation is used to remove..
