Better energy management, lower operating costs

Better energy management, lower operating costs Energy Optimization System for wastewater treatment powered by EcoStruxure Simple and scalable from single to multi-site

Better energy management, lower operating costs Networks Plants To achieve energy-efficiency and cut operating costs, energy management and optimization works across your entire water or wastewater treatment system. Some equipment and processes, like pumps and aeration tanks, are particularly energy hungry and afford opportunities for major savings. Plants 2

Water is the world s most widely consumed product. Everywhere it is a strategic resource. Everywhere it needs to be carefully stewarded and managed to meet the challenges of: access to clean drinking water for all water pollution and treatment regulatory and environmental issues. Water and wastewater utilities have to address these challenges. And they have to do so on a fiercely competitive, cost-constrained water market. Labour costs are rising. So are energy costs and at an even faster rate. Regulatory pressure grows steadily tighter, setting exacting standards for water quality, energy conservation, and reduced waste and emissions. Then, how and where do you cut your operating costs while rising to the challenges of water quality, sustainable development, and ever more stringent regulations? One good place to look and act is your energy consumption. It accounts for 30% of facilities operating costs. You can, of course, lower it by making processes more efficient. Leakage, waste, and carbon emissions are all signs processes still leave room for improvement. Even when their efficiency is maximized, operating costs are still likely to be too high. The most effective, most efficient, and most sustainable solution is to manage and optimize your energy use. It is a challenge that Schneider Electric TM can help you turn into an opportunity. Make energy management part of your operating routine In recent decades information and communication technology (ICT) has been key to reducing production and operating costs in process industries. Energy management information systems (EMISs) leverage ICT s intelligence to make further savings and help build a resource-efficient, sustainable future for the world. But margins are tight, competition fierce, and every operating second counts. It is critical that EMIS systems should not be disruptive. You need an EMIS that is not financially disruptive. One that you account for in your operating expenditure no capital investment. You need an EMIS that doesn t disrupt your site s machinery or processes when you install it. One that is designed to be scalable to your needs and means. And simply, unobtrusively becomes an integral part of your control system. And an EMIS has to be smart. That s what makes it intuitively simple to use. No need to spend time keying in data. It supplies the intelligence displays of meaningful operating data that are simple to interpret and act upon. An EMIS should slip unnoticed into your processes and budget unnoticed, that is, until you notice the gains. 3

Turn water and wastewater challenges into opportunities Turn challenges into opportunities? We believe that s the way to go. Because the bigger the challenges, the bigger the opportunities. The industry s biggest opportunity is its energy consumption, mostly electricity on average up to 30% of operating costs. Energy: huge potential for operating cost savings What s more, regulations are challenging the water industry to conserve energy, improve water quality, and control carbon emissions. On the deregulated energy market you can and must use your energy better and stamp out waste. Stakeholders make similar demands. Increasingly, they challenge you to show you know economy and ecology share the same root. It makes economic and environmental sense to see energy efficiency and sustainability as ways to cut costs and optimize your treatment processes. Utilities are responding by making energy management an integral part of their strategy whatever the number, size, and type of their sites and regardless of whether they are existing facilities or new ones. 5% Primary treatment Specific electrical energy consumption for primary treatment 25% EMIS can save utilities up to 5% just by making real-time energy intelligence available to operators and managers. This intelligence is actionable and can help find ways of cutting operating costs by up to 25%. Non-production zones: 3% 30% Energy consumption can account for, on average, up to 30% of a site s operating costs. 62% Secondary treatment Specific electrical energy consumption for biochemical oxygen demand removal 4

Energy management makes sense economically and ecologically 15% pre-treatment zones Specific electrical energy consumption for sludge dewatering Specific electrical energy for wastewater lifting CO 2 emissions related to chemical use 15% Sludge treatment On-site energy recovery: - biogas from sludge - incineration Water turbines Decision-makers and plant managers worldwide have already homed in on energy management and optimization. It is proving an invaluable aid in significantly reducing energy-related operating costs and ensuring sustainable, quality water supplies. Aeration tanks account for between 30% and 60% of a plant s total energy consumption. The ways in which energy management helps optimize energy use and reduce related costs include: > monitoring, measuring, and reporting energy consumption. > appraising and comparing sourcing contracts against real consumption. > assessing alternative on-site power generation from sources like biogas from wastewater, hydraulic turbines, and solar power. > comparing energy use and costs across plants, processes, and loads to spot opportunities for improving energy efficiency. For example, aeration tanks account for between 30% and 60% of a plant s and site s total energy consumption. > drawing up targets and action plans in order to improve energy management. Energy management can help you: > continuously monitor, measure, and report emissions. > compare sites and processes to better understand and quantify CO 2 emissions. > establish priorities for effective GHG emissions management. Local authorities and professsional bodies address more and more the issue of greenhouse gas emissions. They publish carbon emission recommendations and some wastewater plants conduct carbon inventories. 35% Research Energy savings when you combine an audit with an auxiliary power consumption system. in the United States finds that sewage treatment plants use about 1.5% of the nation s electrical energy to treat over 47 trillion cubic meters of wastewater a year. 5

Energy efficiency, driving global research A growing number of non-profit professional water organizations conduct research into ways of helping the wastewater industry meet regulatory standards and concerns over environmental sustainability. They have put energy efficiency at the top of their agenda. The American Water Works Association (AWWA), with its 56,000-strong global membership, is one such organisation. As part of a research partnership with the California Energy Commission, a public body, it has produced an energy efficiency roadmap for the water and wastewater community. It identifies five key issues: Rising electricity costs to meet stringent water quality requirements Rising electricity costs to enhance water supplies Improving reliability to mitigate problems of grid and restructuring Lack of a system-level energy-water link perspective for increasing energy efficiency Non-technical barriers to optimize energy use and to foster energy savings. An Energy Managament Information System can make the difference kwh Baseline Energy measured recorded Measurements recorded during the reference period Implementation of Energy Management Information System Without EMIS Measurements recorded for comparison to the reference Energy savings With EMIS Time Our Energy Management Information System can help you meet these objectives when used as part of our comprehensive approach to energy management. In addition to achieving energy cost savings of up to 30% off your existing installation, you will also gain visibility across your entire water network for optimized process management that can help you reduce or even eliminate energy waste in real time. 6
