Interim Groundwater Treatment System <br /> O eration Maintenance and Monitoring Manual <br /> 2.0 START UP/SHUT DOWN PROCEDURES <br /> 2.1 START.UP PROCEDURE <br /> Pre-check <br /> 1. Prior to operation, the carbon in each vessel must be wetted with clean water and allowed <br /> to de-aerate. First, the adsorber's vent line should be opened to to the atmosphere, then <br /> clean water should be introduced into the adsorber's outlet connection and the water filled <br /> vessel should set for about 24 hours. After this time, close the vent line and reconnect <br /> the outlet piping. <br /> 2. Visually inspect carbon vessels, manifold, and visble piping joints to make sure <br /> everything is in place and properly connected with no liquid leaks. <br /> 3. Check water level in extraction well to insure that static level is at least 3 feet above the <br /> level of the pump motor. <br /> 4. Check position of groundwater flow control valves: <br /> a. When starting the pump for the first time, the discharge valve should be <br /> closed approximately one-third. <br /> b. Carbon units should be plumbed in series. <br /> c. Holding tank discharge valve should be closed until Iaboratory results <br /> confirm non-detect results and/or WDR permit has been issued. <br /> Startup <br /> 1. If everything above is OK flip pump circuit breaker to the on position. <br /> 2. The pump should take approximately 2 seconds to develop full pressure upon initial <br /> startup. <br /> 3. Once the pump is operational, adjust the well valve to achieve the desired flow rate. <br /> 4. Monitor drawdown in the well to ensure that the pump always remains submerged. <br /> 5. Monitor the flow rate to ensure proper cooling of the pump. The pump should not be <br /> operated at less than 0.2 gpm. <br /> 6. You may need to adjust the fluid level switches for optimum operation based upon <br /> drawdown. <br /> roeklo&mmanl <br />
