Each system has a Kinetico filter, softener and carbon system, followed by Reverse Osmosis. The water is then pumped to the laboratories via Ion exchange polishers, ultraviolet treatment and 0.2 micron filters.
The system also includes a 2,000 litre storage tank with a ultraviolet and Ozone combined system attached to it so that the water purity is maintained whilst in storage. Given the high volumes of water in production it was agreed that a Kinetico non-electric system would be beneficial as it operates on water pressure not electricity saving power costs in the long term. Plus it can keep operating should there be a power outage or natural disaster, such as the Brisbane floods a few years ago.
Shane explained the rigorous testing the water under goes each day. “We test the water every day for resistivity, monthly for bacteria and have the systems serviced twice a year by the Continental Water Service Technicians to make sure all the mechanical and hard ware equipment is functioning.
“The beauty of the system is that it allows us to always shut down one system and switch it over if we notice our water restivity has hit 10 megohm or there is an emergency. As a further safety measure should both System A and B fail portable DI tanks are available which can be attached to a tap to deliver Type II water for 48 hours. We also have a 90 day SDI service contract in place with Continental Water. However if a systems SDI tanks needs replacing we just call the guys and they switch over the SDI tanks within a few hours of the call”.
Shane did point out that the SDI system and related 90 day service program is highly effective as the water quality from the SDI system is such that the RO system does not have to work as hard which has meant the membranes life has been extended well beyond the normal two years. When asked if he was happy with the system, Shane highlighted
“I’m told that our water system is state of the art by visitors to the laboratories. We have more than enough quality water to meet the demands of the laboratories and all their Pure Water needs.”
