PACE Zenith Awards 2012: Finalists for Water & Wastewater

Bluetongue Brewery
Recycled Water Treatment Plant/Green Energy Plant for Bluetongue Brewery

Bluetongue Brewery Recycled Water Treatment Plant/Green Energy Plant for Bluetongue BreweryPacific Beverages' new Bluetongue Brewery in NSW features a waste water treatment plant which produces green energy in the form of biogas from the first anaerobic digestion.

In addition, about 50% of the effluent water is recycled following further treatment and polishing treatment steps.

This achieves world's best-practice water reuse standards while providing renewable green energy recovery. Bluetongue is able to target a reduction in water usage to 2.2 litres of water for every litre of beer produced against a global average of 4-5 litres.

The anaerobic pretreatment is followed by treatment processes involving an aerobic membrane bio reactor and reverse osmosis.

The process has demonstrated its suitability for application in the food and beverage industry in Australia which consists of for some 20,000 companies producing more than $80 billion worth of local and export products in markets increasingly focused on producers' clean, green production credentials.

The plant – engineered jointly by Australia's CST Wastewater Solutions in partnership with Global Water Engineering – has achieved all performance targets set.

Tyco Flow Control Pacific
Nepean River Weirs Environmental Flow Release and Fish Passage Control System

Tyco Flow Control Pacific Nepean River Weirs Environmental Flow Release and Fish Passage Control SystemThe Nepean-Hawkesbury upgrade was initiated to allow for new environmental flows in the river system and improve fish passage in the water.

Critical to the success of this upgrade was the design and implementation of a flow control system by Tyco Flow Control to monitor and record flow parameters associated with water flows through the weirs.

The scope of the Nepean Hawkesbury project posed significant challenges for the team because the waterway was comprised of eight individual weirs — each with its own individual set of fluctuating process variables that displayed no clearly defined limits.

Since this was an environmental project Tyco was, in effect, attempting to automate a 'live' river. Many standard equations that would have been useful in automating a 'controlled environment' were considered inappropriate or just simply didn't work under these conditions.

The control system continuously monitors the total environmental flow and adjusts the position of the valve to reach the set point EFS (MLD) taking into account flow through the fish passage and spill over the weir crest. Valve position adjustments are carried out in a single movement. When the set point is reached, the valve movement will cease and hold for 15 minutes before the next adjustment if the set point has deviated.

CST Wastewater Solutions
DAF Treatment to Achieve Tough Wastewater Targets

CST Wastewater Solutions DAF Treatment to Achieve Tough Wastewater TargetsA dairy product company is achieving high efficiency discharge targets from a new $1.5 million wastewater treatment facility for treating of effluent from its Southern NSW manufacturing site.

The company chose a high-performance high-efficiency DAF (Dissolved Air Flotation) system, designed and installed by CST Wastewater Solutions.

The wastewater treatment plant is capable of treating 300,000 litres of effluent daily, meeting the local council's demanding discharge standards as well as reducing the discharge fees paid to the council.

The DAF system at the plant was regarded as preferable to costly microbial treatment because the dissolved air flotation process (DAF) was straightforward with a favourable ROI.

DAF treatment reduces the high levels of Suspended Solids (SS) and Biological Oxygen Demand (BOD) in the wastewater sufficiently to allow discharge into the local authority's sewerage system. The DAF treatment process at the dairy company includes a 94,000 L buffer tank, with the floated sludge being collected in a smaller 30,000 L tank.

The DAF process introduces micro bubbles into the wastewater and with the aid of chemicals removes suspended matter, reducing the pollutant levels in the wastewater. The bubbles released by the DAF process carry the suspended matter to the surface of the flotation cell, where the matter is removed by a rotating scoop or surface skimmer.

Yarra Valley Water
Yarra Valley Water Host SCADA Upgrade Project

Yarra Valley Water Yarra Valley Water Host SCADA Upgrade ProjectAfter a strategic review of their SCADA domain, Yarra Valley Water (YVW) determined that upgrading their software applications, including replacing their legacy text-based SCADA system, was a critical factor to achieving their future business goals.

This $3 million project will align YVW with industry best practice and standards for SCADA system software and help to deliver a more efficient and effective service to customers.

One of the critical objectives of the project was to develop a SCADA system that provided high level security for today's environment, while also ensuring the crucial business objective of no vendor lock-in for service delivery.

By utilising the extensive templating feature set of ClearSCADA, Schneider Electric were able to deliver a system that any of the approved System Integrators working for YVW can work on without fear of compromising the integrity of the Host SCADA system.

To help achieve this, the Schneider Electric project team provided tools such as ClearSCADA Configuration Management System, implemented a Test and Development Server regime and a Mobile data application.

These tools are an integral part of the overall SCADA solution and provide YVW with a world class SCADA system. While ClearSCADA is an "out of the box" SCADA application that has a multitude of inherent features, this project built on the "base" system with these added features that go beyond the traditional solution offering.

These additional features make sure the on-going maintenance and expansion of the system is managed correctly with a high level of security and auditing. 

Vertical Screen Increases Wastewater Treatment Efficiency

Frucor Vertical Screen Increases Wastewater Treatment EfficiencyA compact vertical screen has been installed by Frucor, the market leader in energy drinks in Australia and New Zealand, to remove the solid debris from factory wastewater before its discharge into the sewer.

The vertical screen provides the company with an automated process that requires far less labour than the previous flatscreen method, which necessitated regular removal of the screens by forklift, followed by hand cleaning.

The vertical screen at Frucor is positioned between the below-ground sedimentary sump and the main sump, which both hold wastewater from the entire manufacturing plant at the Manukau City site.

After the screen has removed solid material from the wastewater, it is pH corrected and discharged into the sewer. The solids are mainly fruit pulp, but also include extraneous debris such as plastic bottle caps and hairnets. This material is discharged into a bin for disposal.

The screen lifts to more than six metres for discharge and can be retrofitted into existing pump stations with depths of up to eight metres. The high-strength shaftless spiral requires no bottom bearings.

SAGE Automation
State Water iSMART (integrated Surveillance, Monitoring, Automation & Remote Telemetry) SCADA Upgrade Project

SAGE Automation State Water iSMART (integrated Surveillance, Monitoring, Automation & Remote Telemetry) SCADA Upgrade ProjectIn April 2010, State Water released a tender to the market for the design and construction of a fully integrated SCADA System to support all aspects of State Water’s delivery and management systems.

SAGE provided a full set of electrical control system drawings. These included topology drawings and interconnection and schematic drawings.

SAGE undertook the programming of the SCADA system along with design review phase which incorporated the production of detailed process functional specification on which the SCADA programming was based. This was a highly interactive stage with extensive input from the client to ensure that the end product met or exceeds operational and functional requirements and expectations.

State Water now has the technical infrastructure in place to allow for the increasing needs of securing critical infrastructure into the future and a single interface to all of their state assets which will allow them to add enhancements in the future and real time reporting to the business across the whole state.

Maintenance personnel have 24/7 access to a system that allows them make business decisions based on the network as a whole – for example someone 200km downstream can make decisions based on a dam level upstream.
