Kaeser delivers high quality compressed air to Malabar WWTP

As part of the Malabar Waste Water Treatment Plant Process and Reliability / Renewal Improvement Project being delivered by 4Malabar, an ageing compressed air system at the plant was recently upgraded with three Kaeser CSDX series rotary screw compressors, along with a Sigma Air Manager 4.0 compressed air management system. Australia’s largest water and wastewater service provider, Sydney Water is a State Owned Corporation wholly owned by the New South Wales Government. Sydney Water collects and treats around 1.5 billion litres of wastewater each day through a network of over 25,000 kilometres of wastewater pipes, 677 pumping stations, 14 water recycling plants and 16 wastewater treatment plants. Malabar Waste Water Treatment Plant (WWTP) is Sydney Water’s largest wastewater treatment plant. It has an average daily discharge of almost 500 ML. A significant project was initiated at Malabar WWTP to improve the reliability of the processes that treat wastewater, to ensure Malabar WWTP continues to comply with its environment protection license requirements, improve safety and working conditions and reduce operating costs. This will ensure that Sydney Water continues to deliver great value for their customers and better conditions for their staff. The Project is being delivered by 4Malabar, an alliance between Sydney Water, John Holland, UGL Engineering and GHD. Work on the Improvement Project started in 2014 and is expected to be completed by mid-2019. Since work has commenced, a number of improvements have been completed and include an upgrade of the ageing compressed air system. Compressed air is used for a number of plant site services across Malabar WWTP including valving, pneumatic actuation and sparging. A reliable and efficient supply of quality compressed air is critical to deliver these site services and was therefore a key criteria in selecting the new system. Following a successful tender process, three Kaeser CSDX […]

Expert calls for grid renationalisation

A publicly owned national electricity grid is the logical solution to Australia’s energy crisis, according to University of Queensland economist Professor John Quiggin. In “Grid Renationalisation – a discussion paper”, published by Flinders University’s Australian Industrial Transformation Institute, Professor John Quiggin said electricity reform in Australia has been a comprehensive failure since the creation of the National Electricity Market (NEM) in the 1990s. “We’re past the point of tinkering; energy instability is compromising our growth and economic progress,” Professor Quiggin said. “Tweaks to the system, such as those being considered in the Independent Review into the Future Security of the National Electricity Market, will not resolve the fundamental failings of a privatised and fragmented system subject to multiple regulators. “The price increases of the past decades and the series of recent breakdowns reflect systemic design flaws, exacerbated by the failure to take appropriate account of the implications of climate change. “The appropriate policy solution is a unified, publicly owned, National Grid encompassing the ownership of physical transmission networks in each state and interconnectors between states. “It would be responsible for maintaining security of supply and planning the transition to a sustainable, zero emissions, electricity supply industry. Professor Quiggin said that some would describe a publicly owned National Grid as “unthinkable”. However he said it was the only coherent response to the failure of neoliberal electricity reform, just as the establishment of a publicly owned National Broadband Network was the only feasible response to the failure of telecommunications reform. “And, in the light of the political upheavals of 2016, the idea that any political possibility should be dismissed as unthinkable appears obsolete,” Professor Quiggin said. AITI Director Professor John Spoehr said the paper lays down a challenge to governments of all persuasions to set aside politics and pursue policy that is […]

World-first universal chute design cuts costs and downtime

A multidirectional rotating underground coal chute system that can be installed in less than a single shift at a typical mine has been developed by Chute Technology in what the Australian technology and manufacturing partnership believes is a world first. The cost-saving universal chute – which can rotate output through 160 degrees left or right – can remove completely the need to custom-manufacture individual chute types to fit the confined spaces and particular angles of individual mines. The versatile bolt-in system – comprising a complete integrated structure from head end to conveyor outlet – features a rotating outlet beneath the head that can be angled to any position required to facilitate product flow. In addition to radically reducing the labour required for manufacture and installation, the chute’s ability to be installed in a fraction of the time of custom chutes minimises downtime by keeping production moving when chutes wear out. “This is a brilliantly simple breakthrough in cost and time saving at a time when the mining industry needs it most to maintain production. The benefits are obvious when you look at the basic concept, but we don’t know of anywhere else in the world where it has been done,” says Chute Technology Partner Mr Tom Woods, whose experience of coal chute manufacture through family company T.W. Woods Construction extends back more than 40 years. The new chute system – of which the first example has already been produced – is the result of the analytical, design and manufacturing experience of each of the three Principal Partners in Chute Technology, who have combined experience of more than 80 years in a wide variety of resource industries including coal, iron ore, alumina and limestone across Australia, the USA, South America and South Africa. The company’s technologies are also applicable to gold, […]

Push to reform electricity market gathers pace

The City of Sydney has teamed up with Australia’s major property industry group and a leading environmental organisation to push for a change to make electricity cheaper and cleaner. Recognising that local generation is a win for the environment, businesses and consumers, the Property Council of Australia and the Total Environment Centre have joined with the City to ask the Australian Energy Market Commission (AEMC) to change the rules that govern the electricity market. Across Australia, a fundamental shift is occurring as more and more businesses and households are generating and exporting local electricity. Local generators range from office buildings with generators in the basement through to sugar mills making electricity from waste heat to residents with rooftop solar installations As well as saving money for themselves, local generation benefits all users by bringing down the costs of transporting power across long distances from remote power stations (can be more than half the cost of electricity bills for both households and businesses). Unfortunately, electricity rules in Australia have not kept pace with change. Under current rules, full network charges are still payable if an office tower with its own generator sends surplus power to the building next door or across the street. This fails to recognise the savings made from not using the long-distance networks of poles and wires. The proposed rule change would ensure local generators receive a credit for surplus power exported to the grid which reflects its economic value – increasing the financial return for local energy projects, making the electricity network more efficient and lowering electricity prices for all consumers over time. Lord Mayor Clover Moore said she was delighted to join the Property Council and the Total Environment Centre to push for a rule change that would encourage local power generation. “For years the City […]

Remote detection of oil & gas infrastructure corrosion

Corrosion and it’s degradation of oil and gas infrastructure-pipelines, rigs, towers and refineries-represents an annual cost of many millions of dollars to the industry. There are thousands of kilometres of pipelines operating in more than 50 countries around the world. They form the gathering systems joining wells to process facilities and the distribution system delivering product to refineries and markets. The overwhelming majority of petroleum pipelines are constructed from metal and, whether buried or on the surface, they are all exposed to a range of physical, climatic and chemical environments that can cause corrosion. The corrosion of steel is accelerated in harsh environments, especially coastal, tropical or desert, where high salt levels or extreme temperatures can accelerate the rate of decay. It is important that owners of high-value assets understand the cost implications of ignoring the effects of corrosion. There are many advantages of planning for corrosion control and mitigation, two of which are that the life of an asset can be extended and maintenance time and costs are reduced. As part of the regular technical program, the Australasian Corrosion Association (ACA) is hosting a one-day technical event in Melbourne on 21 May where the latest challenges and developments in the materials engineering and corrosion control for both onshore and offshore environments will be discussed. Sessions will focus on the remote inspection and the identification of hidden corrosion within oil and gas infrastructure. Speakers and participants will have the opportunity to share their work experiences, case studies, best practices, engineering guidelines, and failure analysis in a technical exchange open forum, aiming to look at new technologies and methodologies to fill the gaps in these industries. The events are aimed at oil and gas industry personnel, such as Asset Managers, Structural, Process and Maintenance Engineers, Specialist Contractors and Asset Condition Inspectors, […]

Green energy orb environmentally outstanding

A spectacular orb-shaped green energy storage facility being installed at one of Australia’s largest beef processing plants is helping to demonstrate how industry can profit from environmental initiatives. The 6000m3 capacity flexible pvc-coated polyester fibre flexible storage tank collects biogas produced by the new Global Water Engineering COHRAL(TM) Covered High Rate Anaerobic Lagoon being installed by CST Wastewater Solutions at Oakey Beef Exports on Queensland’s Darling Downs. To be commissioned next year, the plant will extract green energy biogas (methane) from its waste water streams to replace millions of dollars worth of natural gas currently consumed at the abattoir. The 26m high flexible storage tank – one of the world’s largest of its type – features resilient flexible double membrane storage so that gas produced by the COHRAL plant can be safely stored separately from the gas generator. Use of the separate flexible tank for gas storage provides security against leakage, with gas securely contained in the tank instead of being more loosely contained under lagoon covers. The Sattler biogas storage design selected for Oakey Beef has been tested and proven over decades and now is an integral feature in the design of modern waste water treatment plants worldwide. They are engineered to be permanently gas-tight with high operational reliability and optimum safety. “The safe, durable and environmentally harmonious COHRAL(TM) technology deployed at Oakey Beef can be widely applied worldwide to food, beverage and agricultural and primary processing plants. Oakey Beef Processing and its owners Nippon Meat Packers have taken a far-sighted initiative that opens the way to cleaner, greener and more profitable industry performance,” says CST Wastewater Solutions Managing Director Mr Michael Bambridge, whose company represents the GWE COHRAL(TM technology in Australia and New Zealand. The COHRAL(TM plant (with alternative view of the flexible storage tank above) is expected […]

Maintenance for mine profitability

Mining operations and manufacturing facilities rely on the continued safe operation of vehicles and machinery to maintain profitability. Any equipment failure can be expensive in terms of lost production and cost of repairs. An estimate for the cost of lost production for a single dragline is $8000 per hour in Australia making any breakdown very costly when it might take weeks for a replacement part to be available. One way to minimise losses is to continually monitor plant and machinery using non-destructive testing (NDT) methods to ascertain component health, and monitor mechanisms for damage. Phased array ultrasound can enhance day to day inspection of surface mining equipment, thereby improving safety and keeping critical equipment operational. However, it is important that inspections are performed with minimal down time, so need to be planned and coordinated to ensure that critical parts are available when the maintenance is carried out. As part of the technical programme at the recent Australian Institute for Non-Destructive Testing (AINDT) Conference in Brisbane, Nicholas Bublitz, a Global Product Support Specialist with Olympus Scientific Solutions America (OSSA), reported on how the use of phased array ultrasonics could improve surface mine profitability. NDT is a group of techniques used to detect discontinuities in materials or components without causing damage or permanently altering the article being inspected. The AINDT Conference provided opportunities for NDT and maintenance professionals to meet and discuss the latest advances in NDT from around the world. Leading corporate members of the Institute, such as Olympus, displayed and demonstrated some of their innovative, precision analysis instrumentation and applications supporting NDT. “NDT methods like ultrasonics, eddy current and radiography—along with condition monitoring techniques such as oil and vibration analysis—play an important part in predictive maintenance programs and help reduce unexpected expenses,” Bublitz said. Outage and emergency repair costs can […]

India deal launches Australian firm’s global biofuels division

Australian biofuel developer, Algae.Tec will join forces with India’s largest private sector enterprise, Reliance Industries, to take its innovative technology to the market. Western Australia-based Algae.Tec has partnered with Reliance Industrial Investments and Holdings Limited (RIIHL), a subsidiary of the Reliance Group, to build a pilot biofuels plant using its algae fuel technology. RIIHL will make an initial investment of A$1.5 million with an additional A$1.2 million to follow. The plant is designed to tailor the technology for local settings and produce two barrels of biofuel a day in the pilot phase. The partners will work together towards commercialisation, with Reliance having exclusivity of the technology in India. The companies plan to take the technology to other parts of Asia to help meet the growing demand for biofuels. According to Bloomberg News, India is aiming for 20 per cent of its fuel to come from clean sources by 2017. Algae.Tec Managing Director Peter Hatfull told RenewEconomy that the algae technology had the potential to make a significant impact on India’s energy and environmental requirements. ‘India is a perfect market place for our technology. It is an absolutely gigantic market,” he told the magazine. Talking about the partnership agreement Mr Hatfull said, ‘This is a very exciting step forward. This level of financial backing and ongoing support is just what Algae.Tec needed. ‘It’s a fact of business life that emerging companies need funding injections and the technical grunt of this type to transition into the commercial phase,’ he said. Austrade’s Senior Trade and Investment Commissioner, Nicola Watkinson said, ‘As Indian companies continue to drive innovation programs to improve their competitiveness at home and abroad, they are considering Australian businesses and research institutions for mutually beneficial partnership opportunities. ‘They are on the lookout for joint research projects, or to develop and commercialise […]

Hope for Australian renewables fading fast

Deployment of solar PV has grown at a 48% compound annual growth rate since 200 in Australia. Construction of the southern hemisphere’s largest solar PV plant is getting underway. This follows swiftly on from the announcement that Australia has recently completed its two millionth small-scale renewable installation, just eight months after reaching the initial million mark. On first glance it appears Australia’s time in the renewable sun is just around the corner. Deployment of solar PV has grown at a 48% compound annual growth rate since 2005, and the state of South Australia generated over 25% of power supply during peak output in January. Yet AGL Energy’s 102MW Nyngan Solar Plant provides a false glimmer of hope for Australian renewables, which are struggling to break through the billowing smoke of the fossil fuel industry. The Verdantix Energy Profile of Australia, highlighted how power generation is overwhelmingly dominated by fossil fuels, with coal generating 70% of electricity, dwarfing both wind and solar at 2% and 1% respectively. It appears the clouds are gathering for renewables as the government is planning to water down the Renewable Energy Target – a subsidy scheme which has underpinned the surge in solar and wind investment in recent years. “Elected in September 2013 on a mandate to scrap the carbon tax, the Coalition is on the warpath to put renewables on the backburner.” Elected in September 2013 on a mandate to scrap the carbon tax, the Coalition is on the warpath to put renewables on the backburner and cement Australia’s dependency on fossil fuels, as it seeks to put the brakes on rising electricity prices. Details released in December on the Emissions Reduction Fund – the cornerstone of the Coalition’s new energy and climate change legislation – reveals that the firms failing to meet emissions reductions targets will most likely go unpunished. With a declining manufacturing […]
