Singapore operates a number of parks under its Wildlife Reserve brand. These include the Singapore Zoo, Night Safari, and the Jurong Bird Park. The newest park is River Safari, the first river themed park in Asia. It will include eight major rivers from around the world including the Mississippi, Congo, Nile, Ganges, Murray, Mekong, Yangtze and Amazon rivers. The exhibit allows visitors to learn more about the various freshwater habitats supported by these river systems.
Such an exhibit requires a sophisticated aquatic life support system to maintain over 1 MM gallons of water. Each exhibit within the park will have its own treatment system to prevent cross contamination between species, keep the animals healthy and make the experience safe and pleasant for the visitors.
The extensive water treatment system will include course screens, drum filters, high rate sand filters, ozone, UV, chlorination, bio filtration and aeration. All of these treatment methods are coordinated to control turbidity, color, bacteria, nitrate, phosphates, dissolved oxygen, pH and other important water quality factors.
The water treatment system recycles water used in the park as part of the facilities overall conservation efforts. The main use for make up water will be for filter back wash and will come from the existing potable water system in Singapore.
