During a 30 day test in September and early October of 2007 it was demonstrated that doses from 1.4 to 3.0 ppm peroxyacetic acid (PAA) with UV doses from 45 to 110 mJ/cm2 were consistently able to bring a wastewater utility using an underperforming UV disinfection system into fecal coliform discharge permit compliance without the need for a costly equipment upgrade. These results were obtained during a challenging operational time. Many of individual samples taken before the test (April through August) and samples taken the first week after the test were at or above the monthly geometric mean discharge permit limit of less than 200 MPN fecal coliform/100 ml. During the testing period treated with PAA as described above fecal coliform values from individual samples ranged from < 10 to 70 MPN fecal coliform/100 ml. Non-compliance indicators, total coliform and enterococcus, were also well controlled during the PAA testing period.
