Recycled water nitrate removal filters
in Brisbane
The Queensland Government Western Corridor Recycled Water project will use Tetra Denite biological denitrification filters in the Bundamba plant, to remove nitrate nutrients from the waterways
Severn Trent Services has been awarded a contract to supply Tetra Denite biological denitrification filters for Stage 1A of the Bundamba Advanced Water Treatment Plant - the first stage of the Queensland Government Western Corridor Recycled Water (WCRW) Project The WCRW Project is the largest recycled water scheme of its kind to be constructed in Australia

First Reservoir Management System passes all tests
The first UK Reservoir Management System has had two years of successful operation, controlling disinfection residual levels and temperature uniformity within large water-containing reservoirs
When completed at the end of 2008, it will also be the largest in the southern hemisphere.
The project involves the advanced treatment and recycling of almost all the wastewater from six existing treatment plants in the Queensland capital city, Brisbane, and the neighboring city of Ipswich, via three new advanced water treatment plants.
A 200km long underground pipeline will be constructed to deliver the purified recycled water to the region's power generators, industry and the major potable water supply system.
The Bundamba Advanced Water Treatment Plant is the first of the new facilities to be built.
The project management team is led by a Thiess/Black and Veatch Joint Venture.
The third step in a six-step treatment process to be used at the advanced water treatment plants involves removing the nutrient concentrate.
This will provide environmental benefits by lowering the amount of nutrients that are currently discharged from the wastewater treatment plants into the region's waterways and Moreton Bay.
Precipitation and clarification processes will remove phosphate, and Tetra Denite biological denitrification filters then remove nitrate.
Together these steps will lower total phosphorous and total nitrogen in the waste stream.
At the completion of Stage 1A, the plant will have the capacity to supply 20ML/d of purified recycled water.
A further stage of construction will increase the plant capacity to 100ML/d, while the total capacity of the three new plants will be more than 200ML/d.
The WCRW Project aims to alleviate pressure on the existing dams and waterways in the region, now experiencing record low levels caused by the worst drought in a century.
