water June 2015 100 water Business One was located just 10m from the entrance to a gift shop and customers often commented on the terrible odour. Immediately after the GDOF was installed the odour stopped. At Chirnside Park in east Melbourne, odorous air released from a manhole after a rising main resulted in many odour problems. As soon as a GDOF was installed, all odour release ceased. Monitoring of the dipstick points to a carbon change-out time of two years. The sewer operator is happy with this carbon life, and that the GDOF is successfully treating the odour. At the Playne Street Foreshore in Frankston, Melbourne, a GDOF eliminated odour complaints from a pump station. The readily accessible foreshore area is a popular destination for people of all ages enjoying the walkways, picnic areas, beach and local restaurants. All sewage odour was stopped immediately after the GDOF was installed. A carbon life of three years is predicted based on monitoring of the dipstick. In summary, GDOF passive carbon bed filters are reliably solving odour problems at air release points throughout sewer networks. They are attractive to sewer network operators due to their low cost and low-maintenance requirements. NEW POWER SUPPLY BOXES MAKE MOBILE AND OFF-GRID WATER DISINFECTION POSSIBLE Off-grid and mobile water disinfection is now possible thanks to a unique product recently released by Australian water disinfection specialists, UV-Guard. A PLC-operated controller packed with integrated features, including the ability to operate on 12V and 24V DC power supplies, now gives UV- Guard’s off-grid and mobile customers the ability to disinfect water via UV treatment. UV-Guard Principal Water Treatment Engineer, Luke Chamberlain, said the company worked closely with customers to ensure the new controllers met their needs. The 12V and 24V DC function was the final option to be added to the new controllers, which boast a number of features. “This option has been added after receiving a number of enquiries from operators of solar-powered buildings and other customers who require UV disinfection but are off the grid. We have also heard from customers who require mobile UV disinfection for commercial and domestic applications,” Luke said. “We have been working in partnership with select customers to ensure these enhancements meet their requirements across the industry. Working with an Australian developer has allowed us to release this new range at a competitive market price while incorporating functionality that would ordinarily bring with it a greater price tag,” Luke said. The 12V and 24V DC PLC controller can control UV-Guard’s UV systems up to a power of 40W. This means that recommended UV dose rates can be provided at flows of up to 60lpm by using the SLF, SLT and S-Series of systems. It can also control the storage tank headspace disinfection systems, the T-series. “We see this as the ideal disinfection solution for drinking water provision and commercial applications for our off-grid and mobile customers,” Luke said. The new range has the following optional features that make installation, operation, monitoring and servicing easy: • Australian-designed and made weatherproof IP65 rated box; • User-friendly service menu and digital display; • Digital lamp hour run meter to indicate when the lamp has reached its operational life; • Integrated UV intensity monitoring to ensure correct UV intensity and sufficient disinfection is being achieved; • Building Management System (BMS) connection for remote monitoring; • Remote controllable.

FIRST PROFESSIONAL PH ELECTRODE WITH BLUETOOTH SMART TECHNOLOGY Hanna Instruments has released HALOTM , the world’s first professional pH probe with Bluetooth® Smart (Bluetooth® 4.0) technology. HALO is a high-quality pH probe with a built-in temperature sensor that can be used virtually anywhere – in the field, laboratory or classroom. Using Bluetooth® Smart technology, HALO transmits measurement data directly to an iPad (third generation or newer) running the Hanna Lab App. This combination frees the HALO from cumbersome wires and the need for expensive meters, taking advantage of the widespread usage and versatility of the Apple iPad®. The Hanna Lab App is a free application that turns the iPad into a full-featured pH meter when used with the Hanna HALO pH electrode. Functions include calibration, measurement, continuous data logging, graphing and data sharing. Measurement and logging of pH and temperature at one-second intervals start as soon as the probe is connected. Measurements can be displayed with tabulated data or as a graph. The graph can be panned and zoomed with the iPad’s pinch-to-zoom technology for enhanced viewing. “Part of our philosophy involves making science accessible to the masses,” said Michelle Salisbury, Applications Manager for Hanna Instruments. “The HALO does exactly that. It has the potential to be a real game changer. It makes it easier and more affordable than ever to do pH measurements. Home users, schools, laboratories ... virtually anyone can perform accurate pH measurements with an iPad, the Hanna Lab App and HALO.” Hanna’s new HALO is available in Australia from 1 July 2015 and the Hanna Lab Application is available free through the iTunes store. Familiarise yourself with the application by selecting DEMO probe in the Bluetooth menu. For more information please visit www.hannainst.com.au. Odours were eliminated at this site at Chirnside Park, east Melbourne.
