News & Events Sponsored by New ABB app highlights potential compressed air energy savings Users of pneumatic valve positioners can now assess the energy efficiency of their valve installations with ABB’s new compressed air calculator app for the Apple iPhone and iPad. Based on the amount of compressed air consumed by conventional positioners, the app shows how using the latest smart positioner technology can help operators to dramatically reduce their energy costs. Easy-to-follow instructions show the user applications exactly what parameters are needed to calculate any potential savings. The user is prompted to enter the number of pneumatic positioners on site, air cost per standard cubic foot and the percentage of time spent at a steady state to calculate the user’s current compressed air energy costs. These costs are then compared to the potential savings that could be achieved using ABB’s TZID-C and EDP300 intelligent positioners, where compressed air is only consumed when required. The app also allows you to measure savings in different currencies, including Sterling, Euros and US Dollars. To find out more information call 0870 600 6122 or email moreinstrumentation@gb.abb.com, ref: ‘Compressed air calculator app’. To download the ABB app, please visit the Apple App store and search for “ABB Compressed Air Calculator”. AURORA WATER REAPS THE BENEFITS OF ON-LINE ZETA POTENTIAL MEASUREMENT Aurora Water (Aurora, Colorado, USA), an award-winning water treatment organization that serves 335,000 customers, is using an on-line Zetasizer Nano from Malvern Instruments (Malvern, UK) to reduce coagulant usage and simplify operations while maintaining exceptional quality standards. Through automated, frequent measurements of zeta potential, the on-line system enables continuous monitoring of the coagulation processes used in the treatment of the water, and is providing new real-time insight into how to optimize treatment. Recent gains include a 17% reduction in treatment coagulant dosage and a simplification of plant operating strategy to reduce energy consumption. “We’ve used a lab-based Zetasizer Nano for some time now to improve and fine-tune our coagulation processes,” said Kirk Watson, Treatment Plant Supervisor. “We find zeta potential data a reliable basis for decision-making, more so than traditional alternatives, so the opportunity for on-line measurement is a positive one. The big plus of an on-line instrument is real-time monitoring, the value of which was really brought home to us during a recent treatment event. The on-line data we collected during the event gave us new insight into a modified operating scheme that we’re now capitalizing on.” This technology is still in its infancy for the water industry but it certainly shows promise.

Barton supports six silo scheme Six new aluminium and stainless steel silos have been installed by Barton Fabrications at IKO plc. The major contract awarded by the specialists in roofing waterproofing is part of a £2million+ plant investment. Capability in providing a single source of liquid and powder storage for IKO’s first silo installation, plus technical support provided during silo specification, helped Barton to secure the order. Three stainless steel and three aluminium silos have been installed at IKO’s Chesterfield site. The stainless steel silos each stand 9m tall with a capacity for 100,000 litres of liquid plasticiser. The 12 metre high aluminium silos are used for dry powders: these contain non-flammable materials in the form of PVC resin and calcium carbonate. The silos are all fitted with load cells, ladders and hand-rails for safety and ease of operation. Commenting on what impressed him about Barton’s service, Andrew McArthur Engineering Manager of IKO plc said: “Barton Fabrications were able to provide a single source of silos for both liquid and powder storage. They guided us through the specification process and liaised with our materials handling engineering company to ensure that the specification, installation and commissioning all ran smoothly. “As the site is close to residential housing, a key requirement of the plant design has been to minimise environmental impact. Barton Fabrications worked closely with us to keep the height of the silos to the level of the roofline. The construction quality of the vessels has also been impressive.” Barton Fabrications is the UK’s leading silo manufacturer for the food and plastics industries. The company regularly works closely with all the key European materials handling engineering contractors simplifying the silo specification process and ensuring trouble free installation and commissioning.

Waste acids and alkalis are among the unavoidable by-products which are generated in the manufacturing process of Semiconductors and these liquids require treatment prior to them being discharged to comply with emissions laws and regulations. Previously, mechanically sealed centrifugal pumps were being used to transfer the effluent waste into a treatment system. However, regular problems were occurring with seal leakages resulting in excessive down-time, regular and expensive repair bills, along with the associated clean-up costs from the spillages. M Pumps magnetically coupled centrifugal model C MAG-P100 in PVDF available from Michael Smith Engineers, was selected by General Waters UK Ltd the filtration and water purification specialists who assist the semiconductor manufacturer in meeting their effluent targets. The combination of the magnetically coupled design and PVDF pump head ensures optimum corrosion resistance and effective containment of the waste acids and alkalis. There are no seals to fail, so leak-free pumping is assured and consequently the manufacturing plant benefits from reduced chemical and environmental hazards. The extended pump operation between servicing also means reduced downtime and the associated benefits. Commenting on the performance of the M Pumps, Gareth Scully, Water Treatment Engineer at General Waters UK said,  “We installed these pumps into our effluent treatment system for pumping effluent dilute acidic waste, replacing  mechanical seal pumps and have found them to be very effective and reliable”. He continued, “The pumps were competitively priced and we would certainly recommend them”.
