GENERAL DESCRIPTION
A Bladder Surge Vessel is a surge control device installed with an Internal Rubber Bladder. The bladder vessel is pre-charged with air to give the required stored energy volume to push water into the network during a surge transient.
The main advantages of Bladder Surge Vessels are there is no need for complicated controls and/or compressor systems. There is absolutely no dissolution of the air into the water and thus no requirement for a permanent regulation system. Once the vessel is commissioned with the modelled pre-charge the vessel will operate automatically, emptying and refilling during a surge transient.
In addition to this, if the vessel is fitted with the recommended level monitoring controls the surge vessel can be monitored on the local SCADA PLC and eliminate the need of regular maintenance. Please contact us for more information on this.
In Australia, we have bladder surge vessels ranging from 100L to 125,000L all which are commissioned and operating. We have bladder surge vessels in VIC and on major projects around Australia including the Victorian Desalination Plant which has 11 x 125,000L Bladder Surge Vessels. These are the largest bladder vessels ever commissioned.
