WATER BUSINESS WATER AUGUST 2014 88 Water Business SAFE WORK AUSTRALIA AWARD FOR ZETCO Zetco Valves has been awarded the 2014 Award for the Best Workplace Health and Safety Practices in a Small Business by Safe Work Australia. Following on from its success in the NSW awards, Zetco was nominated by WorkCover NSW for the National Awards. Commenting on Zetco, the judges stated, "Demonstrating that business of all sizes can make a difference, Zetco took out the small business category for taking the initiative to put in place technology solutions that larger organisations have failed to, achieving both safety and commercial bene ts as a result." Zetco is delighted to have its commitment to WHS recognised nationally. Since 2007, there has been a considerable focus on improving the health and safety of the working environment. This has not only delivered considerable gains in terms of reduced risk, but there has also been substantial progress made in terms of worker comfort, which has ultimately led to increased productivity.

Unfortunately there is a commonly held misbelief that people would be better off without chemicals like chlorine. The fact is, most water systems use chlorine-based disinfectants to destroy germs and bacteria in water that can make us sick. They can be effective against almost all bacteria and viruses as well as algae, fungi, some minerals and man-made chemical pollutants. One of the main uses of chlorine that we are all familiar with is in swimming pools and spas, where the chlorine kills harmful microorganisms that can cause health-related problems. Chlorine-based swimming pool and spa disinfectants help prevent a host of health problems including swimmers' ear, athlete's foot, skin rashes and diarrhoea. An important thing to remember is the chlorine chemical must be stored and treated properly to ensure it is effective in use. A dosing chlorinating unit is used to dose chemicals into water. These chemicals can include chlorine for freshwater systems, corrosion inhibitors for main engine cooling water and pH adjustments of freshwater. The most common applications of a dosing unit are to pre-chlorinate or pH- adjust fresh water, pre-chlorinate evaporated water or bunker water on its way to the freshwater holding tank, or re-chlorinate water before it is distributed. The pre-chlorination systems are normally controlled by ow meters in bunker water ow line and evaporated water ow line respectively. This ensures the right amount of chlorine is dosed into the actual water ow in the water line. Polymaster's innovative new dosing tanks are a safer and more effective solution for storing and dosing chlorine as the Polyethylene material will not corrode -- as opposed to other storing methods that will wear away over time. Furthermore, Polymaster tanks prevent gassing off on pump suction lines by inserting suction lines at the base of the tank. A chlorine-dosing pump adds a carefully measured amount of diluted chlorine to the system as the water passes into a tank. The amount of chlorine in the water needs to be monitored continuously to ensure the level ChemMaster® bunded tank. Polymaster dosing tanks.
