The old water treatment plant was built close to 20 years ago and had been struggling to cope with the water demand and maintaining the product water quality for the past few years. The local council has had to arrange for water trucking from other towns to cater for its needs. This was due to a combination of increasing water demand, worsening of the raw water quality and failure of plant equipment. Global Water was the successful tenderer to design, construct and commission a 700 kL/d Ultrafiltration membrane plant.
Global Water successfully delivered and commissioned the new ultrafiltration water treatment system in July 2015 ahead of scheduled completion date. The new system is designed to handle raw water turbidity from as high as 400 NTU and to produce water of < 0.3 NTU turbidity.
Key features of the ultrafiltration system includes fully automatic cycles for air scouring, maintenance cleans, recovery cleans and membrane integrity tests. The system also has full remote access capability for online monitoring and troubleshooting.
The product water quality achieved was well within the requirements of the specification and Australian Drinking Water Guidelines.
The main feedback from the residents is the increased water pressure that is now available due to the new supply being capable of filling to tanks to their maximum levels. The town is now assured of a reliable and stable system producing excellent water quality for their needs.
