摘要

The Scottsdale Water Campus is a water resource management facility that maximizes the Cityrnof Scottsdale’s (City), recycled water production and minimizes their reliance on the multi-cityrnowned regional wastewater treatment plant. The facility consists of a 20 mgd wastewaterrnreclamation plant (WRP), which reclaims water for subsequent reuse in open access irrigationrnapplications such as golf courses and an advanced water treatment plant (AWT) consisting ofrnmicrofiltration (MF) and reverse osmosis (RO) systems. The AWT provides additional treatmentrnof the tertiary effluent from the WRP for subsequent vadose zone injection.rnIn continuing a vision of maximizing water recycling, the City has begun a project to expand thernAWT facility. The project will ultimately allow the City to produce 20 mgd of product water forrnvadose zone injection.rnAs part of the expansion project, the City is installing additional microfiltration capacity asrnrequired to achieve the new production goals. During the design portion of this project, thernCity made a few cunning decisions, including installation of the new microfiltration equipmentrninside of the existing microfiltration building and membrane system procurement through anrninnovative double design approach.rnThe decision to install the new membrane systems inside of the existing building is noteworthyrnfor a few reasons. The decision allowed the City to save a significant amount of money by notrnconstructing new building space and allowed the City to save existing land for future expansionrnor other uses. However, the decision to install the MF systems inside of the building also placedrnadditional constraints on the construction phase of the project since a significant portion of thernexisting system must remain in operation throughout the construction project.rnThe key decision, to forgo the conventional pilot test-procurement approach for membranernsystem design and instead provide two detailed designs is unique. Use of this approach willrnlikely allow Owners to have more input in critical treatment process decisions and may reducernthe typical project schedule by eliminating the time required for pilot testing.rnThis paper will describe in detail the new procurement approach used to supply membranernfiltration equipment on this project, the results of the new procurement approach andrnobservations made during the construction portion of this project. Additionally, this paper willrndescribe design differences between the two systems, challenges associated with reusingrnbuilding space and the commissioning process used to prove equipment conformance.
