HAMILTON ISLAND HOLIDAY RESORT, AUSTRALIA

CUSTOMER

Hamilton Island Holiday Resort is a popular destination for both national and international tourists who wish to visit one of Australia's tropical coral islands. Hamilton Island is situated on the Great Barrier Reef, off the northeast coast of Queensland, and forms part of the Whitsunday group of islands.

PROBLEM

With the upgrading of the Hamilton Island Holiday Resort to accommodate 1,500 tourists in first-class style, a new source of fresh water had to be found. The resort had originally been supplied from open water dams, which depended on the collection of rainwater. The water had a high salinity content, and although safe to drink, was unpleasantly salty to the taste.

SOLUTION

Ausmos, Australia, one of the Netafim Australia industrial dealers, was commissioned to design, build and install a seawater filters system, including a desalination and water purification plant with the capacity to supply approximately 264,000 gallons of fresh water per day for the resort.

Two Spin Klin, all plastic, 6 x 2" pre-membrane filtration batteries were incorporated, as the primary filtration ahead of ozonization, sand, carbon, and cartridge filtration, before entering through reverse osmosis membrane filters.

SYSTEM DESCRIPTION

System: Two 6 x 2" Spin Klin AAF seawater filter batteries
Filtration Grade: 130 µ pre-membrane filtration discs
Flow Rate: 793 gal/min
Backflush mode Air pressure

During windy and stormy conditions, the backwash frequency is every 20 minutes.

A weekly, routine examination is performed on one randomly selected filter by opening the selected filter and checking for marine growth. Discs are replaced every three months with clean discs which have been soaked in a diluted acid solution to remove calcium deposits.
