Ozwater’17 Conference Abstracts:
How Much Can Be Saved? Energy Cost Reduction at 9 STPs – Author/s: Cameron Staib (Technical Discipline Leader, Process – Asia Pacific – MWH, now part of Stantec), Elena Mejia Likosova (Process/Project Engineer – MWH, now part of Stantec), Nicholas Collins (Process Engineer – MWH, now part of Stantec), Michael Thomas (Unitywater), King Intrapaiboon (Unitywater), Rui Yang (Unitywater)
Ever wished your rates bill was lower? Creating energy efficiencies in sewage treatment operations is not only good for the operator but the customer may ultimately benefit too. In his OzWater 2017 poster presentation, Cameron Staib shares a Queensland utility’s journey to identify energy savings above and beyond those already being realised.
Holistically Optimising Odour Control Spend in Sewer Networks – Author/s: Ari Shammay (Senior Process Engineer – MWH, now part of Stantec/ University of New South Wales), Ian Evanson (Principal Process Engineer – Technical Leader (Odour Management) – MWH, now part of Stantec)
Wastewater odour can be unpleasant for communities and a challenge for Utilities. Local authorities need to balance their operational costs against any odour’s potential impact on neighbouring communities. This week at OzWater17 in Sydney, Senior Process Engineer Ari Shammay will explore how it would be possible for regional councils to reduce their chemical dosing costs without impacting the surrounding community.
Pursuing a Biological Solution Without Bio-Sludge – Author/s: Glen Hadiardja (Process Engineer – MWH, now part of Stantec), Chiew H Wong (Principal Process Engineer – MWH, now part of Stantec), Jose Gonzalez (Sydney Water), Andrew Findlay (Microvi Biotech Inc)
Bio-sludge treatment and disposal can be costly so utilities are exploring techniques to minimise or eliminate it altogether. Process Engineer, Glen Hadiardja, presented at OzWater17 on a pilot trial using MB-N2 technology with a major NSW utility to assess its potential benefits over conventional technologies, including reduced waste sludge production. This presentation is a case study on the implications of emerging technologies on the wider water sector.
Achieving Zero Effluent Phosphorus – The Membrane Treatment Solution – Author/s: C.H. Wong (Principal Process Engineer – MWH, now part of Stantec), Glen Hadiardja (Process Engineer – MWH, now part of Stantec), John McAndrew (Asia Pacific Technical Discipline Lead, Process – MWH, now part of Stantec), V. Corling (Queanbeyan – Palerang Regional Council)
As communities grow, environmental regulators are restricting the phosphorus levels contained in wastewater effluent as it discharges into waterways. Glen Hadiardja’s OzWater17 paper looks at utilising currently available technologies and good operational management to juggle very low phosphorus limit (<0.5 mg/L) and TDS constraints in a semi-closed loop recycled water system.

Below is a selection of published Journal articles and Conference papers from Dr Chi-fai Wan, Principal Engineer (Dams) MWH Australia. Dr Wan has 32 years of experience in civil and dams engineering and published a number of papers on dam design, risk assessment, numerical modelling, internal erosion and suffusion in embankment dams. Currently Dr Wan is MWH Principal Dams Engineer providing advice on dam safety matters to Central Highlands Water and East Gippsland Water in Victoria. He is also leading the design of the upgrade works for West Gellibrand Dam for Barwon Water in Victoria.
