6% as Cl2 solution was performed to oxidize As(III) and Fe(II) and to provide chlorine residuals to the distribution system. In addition to tracking the depth of the NaOCl solution in the day tank, the operator measured chlorine levels 28 to ensure that adequate residuals existed throughout the treatment train. Insufficient chlorine was dosed due to a chlorine fitting leak reported by the operator as starting on February 12, 2006. Using spare parts, the operator made a series of repairs between the February 14 and 21, 2006 sampling events to restore prechlorination.
The control panel contained a modem and a touch screen OIP that facilitated monitoring of system parameters, changing of system setpoints, and checking the alarm status. Run time, standby time, and ∆p settings automatically dictated when the pressure filters should be backwashed (see settings on Table 4-5). The touch screen OIP also enabled the operator to manually initiate the backwash sequence. 2. , manually initiating backwashes and/or changing setpoints in the PLC to accommodate HachTM turbidimeter malfunctions).
