The Cincinnati Zoo uses an ultrafiltration system (UF) to treat storm water. The reclaimed water is collected from fourteen acres of the park, including parking lots, animal exhibit yards, rooftop drains and walking-path storm drains. These combined sources run through a straining basin to a 300,000 gallon retention tank system. From there, the water is
An 8-MGD water reclamation system in Northern California was experiencing membrane fouling that was increasing the required feed pressure to produce water. A membrane autopsy showed that the fouling was caused by silica scale. The system consisted of three trains, each designed to produce 1850 gpm of permeate at a feed pressure of 145 psi.
Why do a Membrane Autopsy? The word autopsy derives from the Greek word “autopsia” which means “to see with one’s own eyes.” Autopsies can identify specific foulants and scalants on the membrane surface, and they can determine the presence of chemical or mechanical damage that has occurred during operation. The data and conclusions from an
AWC is proud to announce that our CEO and Technical Director, Mo Malki, won the AMTA Best Paper Award at the MTC 2017 conference in Long Beach, California. The paper, titled “A Novel Calcium Carbonate Scaling Model for Calculating Maximum Recovery and Inhibitor Dosages in Industrial RO Applications” described three indices developed by American Water
