Background

A large hotel/casino on Queensland’s Gold Coast wanted to reduce its water costs and reduce its environmental impact. One of the most sustainable ways of doing this was to build a water treatment plant using reverse osmosis membranes to produce high quality demineralised water.

The water treatment plant treats Class C effluent supplied by the local council’s effluent treatment plant and produce Class A+ water as defined in the Queensland Department of Health guidelines for use of recycled and non-drinking water   the treated water is used in cooling towers and flushing toilets, saving money on potable water and minimising the impact on the environment.

Solution

1 x 500 m3/day skid-mounted Demineralised Water Reverse Osmosis (DWRO) Plant to provide high quality, demineralised, water.
