3.2 It is understood that the Town will make power, potable water and sanitary sewer <br /> services available for pilot plant use at its' Membrane Water Treatment Plant site. <br /> The District will route temporary overhead power cable from the Membrane Water <br /> Treatment Plants' main power distribution panel to the pilot plant trailer and cargo <br /> container. The District will install buried temporary potable water and drain lines <br /> will be buried from the trailers to the connection with the Town's utilities. <br /> 3.3 Prepare record drawings of the completed pilot plant installations and submit ten <br /> (10)paper copies and one electronic copy to the District and the Town. <br /> 4.0 Task 4-Pilot Plant Equipment Startup and Commissioning <br /> 4.1 The District and various equipment vendor service technicians will conduct <br /> pressure and flow testing of pilot plant components to verify proper operation—in <br /> particular the systems operating at pressures greater than 500 psi. Verify calibration <br /> of instrumentation and communication with the system monitoring and control <br /> system. Once all the equipment is operating properly,begin concentrate treatment <br /> testing at a low recovery rate to establish a steady state baseline operating condition. <br /> 4.2 It is assumed that the Town's treatment plant and peripheral systems are operating <br /> in a stable predictable manner such that concentrate production is consistent. <br /> 4.3 Prepare a Project Start-up and Commissioning Technical Memorandum (TM) <br /> documenting the baseline operating conditions. <br /> 5.0 Task 5- Operate and Monitor Test Scenarios <br /> 5.1 Upon establishing baseline operating scenarios for each pilot plant process, <br /> incrementally increase the recovery, flux rates and other operating parameters in <br /> accordance with the Project Work Plan testing plan until the ultimate performance <br /> objectives are achieved. Periodic chemical cleaning of plant components and <br /> regeneration of the softening resins will be required. <br /> 5.2 Testing is assumed to be completed over a 4 month period to allow sufficient <br /> time(two to three weeks) to evaluate pilot plant process performance and to monitor <br /> processes for potential mineral scaling or equipment problems. During this period the <br /> Consultants field engineer will visit the site daily to monitor and maintain the <br /> equipment. Vendor technicians and District process specialists will periodically visit <br /> the site on as needed basis to optimize the treatment process. <br /> 5.3 If the District determines during the course of testing that the ZLD equipment or <br /> configuration is not appropriate or does not meet expectation, the Consultant may <br /> terminate the test and recommend alternate treatment strategies for the pilot test.
