Real time data visibility Recently, a Canadian water/wastewater operation that encompasses six separate treatment plants recognised its need to not only increase visibility into existing systems, but spot trends that would help better predict its production needs. Because a range of issues might diminish a plant’s ability to deliver water supply - from flow issues and spiking electrical usage to greater-than- average demands by one water user on the network - the operation needed real-time visibility into factors that affect flow. Gaining this information would allow the facility to react to specific issues affecting the fluctuation in demand, without having to risk inaccuracy by ‘guessing’. The water/wastewater operation enlisted Grantek,
an Ontario-based systems integrator and its partner, Rockwell Automation, to identify areas in need of improvement and implement a manufacturing intelligence strategy that could help it reduce risk of downtime and optimise operations. Grantek’s solution is centered on FactoryTalk
VantagePoint software from Rockwell Automation. FactoryTalk VantagePoint software taps into information from systems across operations that has been automatically identified, gathered and stored by FactoryTalk Historian software - including systems developed by a number of different vendors and varying widely in age. The FactoryTalk VantagePoint application provides visibility into production by putting all this data into context through a Web-based reporting tool that gives users a comprehensive picture of the factors contributing to the performance of their operations. By marrying FactoryTalk VantagePoint software with the specific information demands of the water/
wastewater operation, Grantek modelled the physical units of the facility such as high lift pumps and intake pumps, and plant processes such as chlorination and filtration, logged those names into a library, and created drag and drop functionality that provided for a quick and easy migration. The software was scalable and compatible with the operation’s legacy systems, and leveraged the enhanced visibility and reporting capabilities inherent in the application. Grantek’s solution also provided easy-to-use
reporting on key performance indicators, enabling users - whether operator, line supervisor, plant manager or executive - to hone in on the suitable level of detail for their role. Because the FactoryTalk VantagePoint user experience is very intuitive, the water/wastewater operators can now access role-appropriate information with a simple click-through on the Web-based system. “Role-appropriate visualisation is critical to creating
value for our customers,” says Rick Hargreaves, Grantek regional manager. “While an operator needs particular information to make quick decisions on the floor, a manager may only seek high-level dashboard displays that allows taking measure of the whole system with a quick glance.” The software also reduced the amount of operator
time spent on information gathering for regulatory purposes, and highlighted a US$100,000 (€76,000) billing error that had gone unnoticed in the company’s original manual entry spreadsheet system. Yokogawa Indonesia has received an order from
Waskita Karya to supply the automation system for the Petanu water treatment plant that it is building at the Sanur beach resort area on Bali’s southeastern coast for a municipal water utility. The Petanu water treatment plant will produce
300 litres/s of clean water for Gianyar Regency, Denpasar City, and Badung Regency. It is scheduled to start operation in late 2013.
EU hails water treatment moves, but more to be done R
eleased in August, the EU Commission’s Seventh Report on the Implementation of the Urban Waste
Water Treatment Directive to the European Parliament is a measure of how each member state is progressing towards compliance with the Directive and covers the period 2009/2010. The report measures the percentage of compliance that each country has achieved in wastewater collection, wastewater secondary treatment and more stringent wastewater treatment.
Its main findings include: collection rates were at a very high level, with 15 member states
collecting 100 per cent of their total polluting load. All had maintained or improved previous results, although compliance rates remained below 30 per cent in Bulgaria, Cyprus, Estonia, Latvia and Slovenia; compliance rates for secondary treatment are 82 per cent, up four points since the previous report. However there were huge differences between the EU-15, where rates were in the range 90 per cent to 100 per cent, and EU-12, where average compliance was 39 per cent; compliance rates for more stringent treatment to combat eutrophication or reduce bacteriological pollution that could affect human health were
77 per cent overall. EU-12 member states averaged only 14 per cent, whereas Austria, Germany, Greece, and Finland reached 100 per cent compliance
The report also finds that the share of EU territory designated as a sensitive area increased by two points since the previous report, reaching almost 75 per cent. The biggest increases took place in France and Greece. An annex to the report comparing the situation
of 27 European capitals cautioned that only 11 of the 27 had an adequate collection and treatment system in place – despite the fact that the standards were set more than 20 years ago. ■
