AUGUST 2014 WATER 89 Water Business stays within the recommended limits. Too little and not all the contaminants will be destroyed; too much and it can be harmful to our health. The ideal set-up for dosing chlorine in an easy-to-use system is for a dosing pump to be mounted to a small Polymaster dosing tank. For a larger system, larger tanks are available from the Polymaster range. To prevent against the possibility of a tank inside an aged concrete bund leaking chemicals outside the tank and causing a serious OH&S/WHS issue, a Polymaster ChemMaster® bunded tank can be installed. ChemMaster® bunded tanks range from 1,500 litres to 10,000 litres to suit any application and are compliant to all speci cations with lower costs and faster installations For remote or temporary dosing of chlorine, a ChemMaster® bunded tank offers the ideal solution with all pumps and instrumentation mounted into the cabinet, and the tank can simply be put in place and then removed when no longer needed without the need for any civil or constructional works. ChemMaster® tanks are not subject to rainwater ingress and have a lockable cabinet door to keep out unauthorised personnel. For added reassurance, they are constructed from PE material that is totally UV-resistant and will not break down over time in the sun.

We need to reduce the linear ow of water, material resources and energy, through promoting technologies and practices that achieve recovery, re-use and demand reduction. In pursuing this goal, 10 International WaterCentre (IWC) Master of Integrated Water Management participants, from a range of water utilities and elsewhere across Australia including Water Corp, Wannon Water, Melbourne Water, Unity Water and Seqwater, recently spent two-and-a-half days learning how to make the water, food and energy systems that service our cities more sustainable and resilient. This session was the face-to-face intensive part of the module Urban Metabolism: Resource and Energy Recovery Systems, which is delivered using a blended approach of face-to-face and online teaching. The participants learned about the direct and embedded (or virtual) ows of water, food and energy in our cities. They evaluated the sustainability of those ows and ways that our cities might become more resilient to external resource or economic changes by recovering and recycling water, nutrients and energy. They learned how different elements of our urban water systems use energy, and where the biggest 'bang for the buck' opportunities lie for reducing water-related energy and recovering energy from water systems. Mass balance modelling was offered as a key technique for characterising and assessing the feasibility of recovery and recycling approaches at different scales and the functioning of different water recycling DELIVERING PUMPING SOLUTIONS Call us to discuss your applications: Melbourne 03 9793 9999 Sydney 02 9671 3666 Brisbane 07 3200 6488 Email: email@example.com Web: www.brownbros.com.au HYDROVAR, the modern variable speed pump drive is taking pumping to a new level of flexibility and efficiency.
