Water Journal : Current Feb 2016
13 www.awa.asn.au Association news NEW IMPETUS FOR TECHNICAL PAPERS To ensure the technical papers published by the Association benefit as wide an audience as possible and investigate an array of water issues they've been given a new digital home in the Water e-Journal. By visiting the Water e-Journal at bit. ly/e-Journal, members can access all technical papers in a fully searchable, shareable and printable format. Current will publish executive summaries of the most recently received technical papers in each issue, with the full text and data available online. Association Marketing Manager Ashleigh James says the new approach will improve knowledge-sharing among Australian water professionals and boost the profile of work being done by the Association's Specialist Networks."By giving the technical papers a specially built home online, we are ensuring that Association members can access the latest thinking and insights in Australian water no matter where they are, no matter what time of day it is," she said. "A focus on publishing online also means we face no space restrictions, allowing us to increase the quantity of technical papers we publish, ensuring we delve more deeply into the many various specialties of our members." Publishing more papers will in time allow the Water e-Journal to become a fully accredited scientific journal. GO ONLINE FOR THE LATEST WATER NEWS The water sector is ever-changing and developing, which is why the Australian Water Association is now publishing the latest news online every weekday. Contained on the Association's new fully mobile-responsive website, the coverage includes industry, political and scientific updates. Visit bit.ly/WaterNews to read the latest or follow @AustralianWater on Twitter to keep up to date. This is the first issue of Current, the Australian Water Association's new quarterly magazine. It is part of a sweeping refresh the Association has undertaken for all its communication platforms, including a completely new website. While retaining the strong focus on publishing the latest in research and technical expertise held by the previous Water Journal, the new magazine has also expanded its scope to more thoroughly encompass the world of the Association's members. As well as executive summaries of technical papers, each issue will contain news features delving into the social and political issues facing the profession, canvass the biggest industry trends, as well as do more to highlight individual members of the Association and their contributions to the industry. Association President Peter Moore said the new magazine was a vehicle for driving greater understanding and appreciation between the Association's members. "There is an incredible array of stakeholders involved in the Australian water industry and in order to make the best use of our most valuable resource, these different stakeholders need an understanding of the broader contexts," he said. "The Association's members are credible, passionate, collaborative and innovative and Current magazine will reflect those values." MEMBER MAGAZINE GETS CURRENT MAKEOVER INSIDE THE NEW LOOK ASSOCIATION MEMBER MAGAZINE www.awa.asn.au 24 THE ASSOCIATION'S MENTORING PROGRAM HAS PROVED A CAREER-CHANGER FOR SCORES OF YOUNG WATER PROFESSIONALS, GIVING THEM ACCESS TO THE HARD-EARNED WISDOM OF INDUSTRY OLD HANDS. STEWART GIULIANO Giuliano Marcon was an engineer at the very beginning of his journey into the world of water when the Association's mentoring program found him the perfect guide -- CSIRO Professor Stewart Burn, whose decades of experience were vital in helping Marcon chart his own course. Mentee GIULIANO MARCON KNOX CITY COUNCIL, VICTORIA My background is as a production engineer. When I chose production engineering, I was very young, and probably not mature enough to decide what I want to do with my life, but I had to choose. There were a lot of things happening in my life at the time, but later I discovered I felt a lot more connected to the environment, and this piece was missing from my work as an engineer. After about seven or eight years working as an engineer, I decided I had to change direction and change where I would work, so I enrolled in the PhD course and started digging a bit more into water and environmental policies in general, all of which makes a lot more sense to me. I did my PhD in Brazil from 2001 to 2005 at the university of São Paulo's School of Public Health. The proposal was to assess how well São Paulo state's water resource policy had been applied in practice. I'm glad that I made that decision, even if it's a bit later in my life, it was worth it. The Australian Water Association was running a mentoring program, and I was interested, and so I enrolled in the program and met Stewart on the day. We have similar research backgrounds, because my PhD is in water management and Stewart, at the time, was the senior principal scientist for Urban Water Systems Engineering at the CSIRO. Water helped us make the link.

GIULIANO MARCON Industry executive summary wastewater treatment Wes ter nport Water provides water supply and wastewa ter collection and treatment services to anareaof 300km2 about 100 k m south east of Melbourne, centred o n the hol iday resor t of Phil lip Island. Although the ser viced area only has a resident p opul ation of ab out 20,000, it experienc e s pe a ks of over 100,000 pe rsons during eve nts and holiday period s. The C owes wastewater treatme nt plant, which was a conventional ex tended aeration, activated sludge plant with disinfected effluent discharge to Bass S traight, was at full capacity. An anal ysis of treatment options recommended modifying the ex isting plant to biological nitroge n remova l (BNR) rather than constructing a new plant. The upgrade involved converting the ex tended ae r ation proces s to BNR, while increasing the overall plant capacit y to hand le projected influent lo ads up to 2021. The major changes involved: l Incorporating an anoxic zone for biological denitrification; l An internal mixed liquor recycle of up to twice the average daily flow; l Peak wet weather loading is to be handled by a new storm bypass system to protect the biological process to an enlarged storm storage facility. To provide increased capacity, upgrades were made to: l the inlet works l bioreactor l internal pumping station l sludge digester, and l sludge drying systems. The major challenge was to provide continuous operation of the plant within the licence limits during construction. This was managed by careful scheduling of construction activities to select the best timing and duration of individual work components. In summary, the upgrade was complex and challenging, but it was completed on time and within budget with no breaches of the licence effluent limits. The upgrade was completed in June 2015 and since commissioning of the anoxic tank effluent quality has improved despite increases in inflow volumes. A comparison of the effluent quality before and after conversion is given in the table below.
