  • Ultrafiltration Stormwater Recovery System At Cincinnati Zoo Reaches Optimal Performance
    Study January 28 2015 Ultrafiltration Stormwater Recovery System At Cincinnati Zoo Reaches Optimal Performance Source Alkema Solutions Inc The Cincinnati Zoo uses an ultrafiltration system UF to treat stormwater The reclaimed water is collected from 14 acres of the park including parking lots animal exhibit yards rooftop drains and walking path storm drains Those sources are combined and routed through a straining basin to a 300 000 gallon retention tank system From there the water is pumped from a wet well to the UF system producing irrigation water and make up water for various animal exhibits These include underwater viewing of polar bears and sea lions as well as moats for lions cheetahs and African wild dogs The UF stormwater recovery system was showing a drastic deterioration in product flow A contracted service company performed an extensive cleaning They first circulated a competitor s acid cleaner at a pH of 1 6 for two hours followed by an alkaline cleaning at pH 12 8 The high pH cleaner was circulated for about 1 5 hours at 96 F followed by an overnight soak The next morning the system was cleaned for a few more hours with a fresh alkaline solution at pH 12 4 The system was finally cleaned with a second acid solution for an additional hour The transmembrane pressure TMP and flow did not recover to design values Within a few days the product flow started to decrease again until the UF system s operation had to be completely halted The Cincinnati Zoo operations team requested Alkema Solutions assistance in finding an optimum procedure to clean their UF elements A cleaning study was performed in our laboratory and it was determined that a 2 percent solution of AWC UF 428 an alkaline chlorinated cleaner should be applied The
