Any excess ozone from the generator that would result in an ozone concentration that exceeds the target dose shall be vented to the ozone destruct unit prior to injection. An ambient ozone monitor shall be tied to a control switch for the ozone generator to terminate ozone generation if ambient air concentrations exceed health screening levels. A variable speed peristaltic pump shall be used for dosing an aqueous ozone quenching agent, calcium thiosulfate, after the ozone contactors. The peristaltic pump shall be tied to a PID controller to modify the dose based on readings from the inline ozone residual probe. The quenching agent feed tank shall be housed within secondary containment with a minimum volume equal to the quenching agent feed tank capacity. The ozone skid shall have inline instrumentation for monitoring ozone residual with a digital display and capability for data logging. The service provider shall be responsible for procuring all pipes, valves, meters, and miscellaneous parts required for successful installation, operations, and maintenance of the ozone unit. Coagulation and flocculation skid: The service provider shall be responsible for providing a twostage coagulation and three-stage flocculation skid capable of dosing 0.2 to 1.5 mg/l of ferric chloride

16 BL Page 16 coagulant at a velocity gradient of 1,000 per second (/sec), and 1 to 2 mg/l of Clarifloc Polydimethylsiloxane flocculent at a velocity gradient of 60/sec (Table 1). The mixing basin sizes shall have sufficient volume to attain 36 seconds of coagulation mixing and 8 minutes of flocculation mixing. The basin volume shall be adjustable to allow testing of various mixing durations. The coagulation and flocculation mixers shall be variable speed. Water shall be pumped from the ozone skid effluent to the elevated coagulation/flocculation skid located on a platform. Coagulant and flocculent shall be dosed using variable speed peristaltic pumps. The coagulant and flocculent feed tanks shall be opaque and housed within secondary containment with a minimum volume equal to the feed tank capacity. Elevated platform: The service provider shall design a work platform in accordance with all local, state, and federal requirements for working at heights of up to 18 feet. The platform shall allow sufficient room to conduct operations and maintenance as well as sampling of the coagulation/flocculation skid, as well as sample from the top of the filter columns. Design drawings of the elevated platform shall provide sufficient detail for an on-site contractor to construct and install. The platform shall be designed to hold the weight of the coagulation and flocculation skid while operating at a flow rate of 6 mgd and up to 5 personnel at a time. The platform edges shall contain railing the meets all OSHA health and safety requirements. Filtration skid: The filtration skid shall contain four 6-inch ID clear PVC filter assemblies with a total height of up to 18 feet. The influent/backwash water line shall be a minimum of 4 feet below the top of the filter column with an overflow drain to sewer near the top of the filter column. The total column height shall allow for 30% bed expansion during backwash and the backwash effluent line shall be sufficient to minimize the potential for media loss during backwashing. The filters will contain 60 inches of anthracite and 12 inches of sand; this media will be obtained from the Shoal Creek Filter Plant full scale filters. The service provider shall mount these pilot filters vertically using fiberglass unistruts and stainless steel pipe clamps. The filters shall be constructed to allow for downward flow by gravity from the coagulation/flocculation skid. The filter flow rate shall be modulated using motor operated valves (MOV) controlled by both the influent flow meter and the filter level indicating transmitter to maintain a constant 11.5 feet of submergence above the filters. The service provider shall incorporate a clear PVC common header that allows excess filter influent water to drain to the onsite sewer line if needed. Each pilot study filter shall be equipped with a 2-inch connection located at approximately 100 inches from the bottom of the filter to allow for draining the water prior to a backwash and to discharge backwash water. Sufficient space shall be provided below the underdrains to allow for air scour and backwashing. In addition, each filter shall be equipped with online instrumentation shown in the P&ID including an individual turbidimeter, flow meter, level indicating transmitter and modulating valve for flow control. The service provider shall have top of each pilot filter open to allow for filter media sampling from the top of the filter bed. The underdrains shall be comprised of Leopold IMS caps. Amendment dosing systems: The service provider shall be responsible for procuring the tanks, mixers, and feed pumps necessary for adding phosphorous and hydrogen peroxide into the filter influent at the concentrations specified in Table 1. The dosing pumps shall be multi-head variable speed peristaltic pumps (4 heads per pump) to allow for injection of such amendments into the four pilot study filters individually. All tanks shall be opaque and housed within secondary containment with a minimum volume equal to the feed tank capacity. The hydrogen peroxide stock tank and peristaltic pump tubing used for dosing shall be comprised of a chemically-compatible material with a concentration of up to 3,000 mg/l of hydrogen peroxide. Backwashing system: the service provider shall be responsible for furnishing a backwashing system including air scouring and capability for chlorinated or unchlorinated backwash. Filter effluent water will be routed to the 200 gallon backwash water tank prior to initiating a backwash. The air scouring shall have capability to provide 2 to 25 actual cubic feet per minute per square foot (ACFM/ft 2 ). The air scour air compressor shall have a receiving tank with inlet and outlet pressure regulating valves and pressure gauges. The backwashing pump shall be a variable speed centrifugal pump with a capacity of 7 gpm at 20 psi. The pump shall be sufficient to supply 3 to 25 gallons per minute per square foot (gpm/ft 2 ) of flow sufficient to enable up to 30% bed expansion during backwashing. The backwash

17 BL Page 17 tank shall show water level with exterior graduations on a sight-tube and allow for excess water to overflow to the sewer. Chlorine shall be added to the backwash water and be equipped with a day tank, mixers, calibration cylinders, and peristaltic chemical variable speed pumps to feed sodium hypochlorite. The chlorine feed tank shall be opaque and housed within secondary containment with a minimum volume equal to the feed tank capacity. Ranges of anticipated flow rates are shown in Table 1. Backwashing shall have the ability to be manually or automatically triggered by filter run time, headloss, or turbidity. The backwash effluent line from each filter shall be connected to a clear PVC common header to allow the operator to view color and turbidity in the spent backwash water and to collect samples. Finished water tank: The finished water tank shall be a minimum of 200 gallons with an overflow to sewer. The tank shall show water level with exterior graduations on a sight-tube and allow for excess water to overflow to the sewer. A chlorine tank and variable speed peristaltic dosing pump shall be included that meets the specifications shown in Table 1. All stock tanks shall be opaque and housed within secondary containment with a minimum volume equal to the feed tank capacity. Commissioning and training: The service provider shall include an onsite visit for installation, system start-up testing, and training for the pilot operators. Start-up testing shall include leak testing of all components of the pilot (e.g., hydrostatic pressure testing) including backwashing.
