Technology for the reduction of filterable reactive phosphorous (FRP)
During the last decade, the significance of FRP reduction from the water column and the sediment P release control in preventing algal blooms has been recognised. In order to control the P level in water bodies, a number of chemical methods, such as alum or ferric chloride, have been used over the last few decades. However, many scientific studies have demonstrated significant limitations associated with these methods, including the re-release of the sorbed P when physiochemical characteristics of the water body, such as its alkalinity or redox conditions, are changed. In addition, key water quality parameters, such as the ph and conductivity of the water body, can also be affected.
Given the role of the FRP in phytoplankton activity and the limitations of the currently used chemical methods, there is a great need for a technology that can reduce the FRP concentration of the water column and prevent the release of the sediment P under a wide range of chemical conditions (ph, salinity and redox), without affecting the key water quality parameters. The need has been met by a modified bentonite product known as Phoslock.
It removes FRP effectively as it descends through a water column. As it settles, it forms a capping on th e bottom sediment preventing any further release of FRP into the water column.
The product has been demonstrated to have a rapid FRP uptake kinetic, removing 90% of it within the first four hours. In addition, it is shown to operate within a wide ph range (5-11), without any significant change to the ph of the water body.
It performs efficiently in a wide range of water bodies, ranging from natural waterways, aquaculture and a variety of waste waters such as sewage treatment holding lagoons, farm dams, poultry, dairy and piggeries. Furthermore, the removal of arsenate , selenate and molybdate has also been demonstrated.

Rainwater bladder tanks
From Waste Streams - Apr/May 2006

Rainwater bladder tanks
Rainwater bladders are flexible water tanks that can fit under a house. The bladders are claimed to be able to capture up to 500% more water than a standard tank system.
The Rain Reviva system is suitable for sites where a water tank won't fit because of lack of space or where access is difficult.
A traditional water tank will only capture water from one side of the roof, whereas a bladder installed under the house uses the entire catchment surface area of the roof, which means that more rainwater is diverted into the tank.
In addition to the bladder-like tank, the system incorporates an 'inlet diversion' - a 'swing arm' system - that efficiently diverts the rainwater from each downpipe into the water sacs. A pump system then allows the water to be reticulated to a range of devices from the garden hose and the pool to sprinkling systems, and even the washing machine and dishwasher.

Converting wastewater salt into cleaning compound
Dairy companies are closing the recycling
Researchers involved with the Dairy Australia-funded project at Food Science Australia in Sydney are only months away from discovering a way to recycle the salty water that forms in waste milk after the solids have separated from the liquid.
According to Dairy Australia's head of resource management and technology, Neil van Buuren, the researchers are exploring a simple concept that could deliver significant environmental benefits.
"As well as being environmentally responsible, dairy manufacturers would save thousands of dollars by recycling wastewater and reducing the amount of salt in effluent," Mr van Buuren said.
"The salt would be used to make alkaline and acidic cleaning compounds, which would also reduce the need to purchase concentrated cleaners.
"While this discovery would have immediate benefits for dairy manufacturers, dairy farmers should be able to use the same technology on their farms and get the same benefits," Mr van Buuren said.
Researchers in the US have also discovered a new way to clean and disinfect milking equipment using electrolysed oxidising water.
This water is created when the electric current flowing through two electrodes - immersed in a weak salt solution and separated by a membrane - produces an alkaline and an acidic solution.
"The US researchers and Australian researchers have used the same science, but with a different raw produce," Mr van Buuren said.
"The Australian researchers are trying to recycle a waste product, not create a new salt solution," he said.
This project is part of the Closing the Loop initiative which is funded by Dairy Australia and The Geoffrey Gardiner Dairy Foundation. It aims to cut the environmental footprint of Australia's dairy factories. The third research partner is the Department of Primary Industries.

Water reclamation plant unveiled in Noosa
Econova techology treats water like gold
Petrac has unveiled its Queensland designed water reclaimation plant on the Noosa North Shore. With the message that water can be treated like gold, the plant takes good care of delicate environments tht exist in the lowlands of the Noosa North Shore, using the latest membrane technology.
Fewer nutrients and pollutants will flow from the site with the wastewater treatment plant turning out a previously unreachable Grade A + standard.
Petrac's director of development, John /campbell said the $1.2 million installation represented a significant improvement on the wastewater system that the company inherited when it bought the site.
"We worked with the Environmental Protection Agency and our environmental engineers Cardno to identify how we could sustainably reuse wastewater while meeting stringent environmental standards," he said.
The contract involves EcoNova providing the technology that can reclaim wastewater and treat it to a standard surpassing EPA guidelines.
Cardno's project engineer, Michael
chessells, said potable water consumption will be reduced by 10-15% by watering lawns with reclaimed water and because the sewage treatment plant was replaced with the water reclamation plant.

The Honourable Peter Beattie

BILLION DOLLAR FUND TO TACKLE CLIMATE CHANGE
Two new dams and two new weir projects will be built under a new fund worth more than
$1 Billion to be established by the Queensland Government.
Premier Peter Beattie and Deputy Premier and Treasurer Anna Bligh today announced the State Government would legislate to create the Queensland Future Growth Fund to help meet the challenges of climate change and the continued economic development of the SmartState.
Mr Beattie said the fund would be financed from the sale of Sun Retail - comprising the retail business arm of Energex - and the contestable elements of Ergon Retail.
"This massive new fund will position the SmartState to tackle the challenges of climate change through a raft of new innovative technology and infrastructure projects," Mr Beattie said.
"Climate change is a worldwide issue but the impacts can be felt right here in our own backyard.
"Queensland will get drier and hotter. Changes in weather patterns have affected our environment - most notably our water supplies.
"In addition, we must tackle issues such as greenhouse gas emissions and their role in climate change."
Mr Beattie said all details of the new Fund will be released when the sale of the retail business had been concluded and the final price determined over the next twelve months.
He said this was expected to be in excess of $1 Billion.
"As a priority under the Fund we will allocate approximately $200 - $300 million to help accelerate the building of two new dams and two new weir projects," Mr Beattie said.
"Subject to Commonwealth cooperation we now expect these projects to be completed by the end of 2011.
"Together they are expected to deliver up to an extra 235,000 megalitres per annum - this is equivalent to the approximate capacity of more than three new Hinze Dams.
"We will build a major new dam on the Mary River in the Gympie region and bring forward the construction of the promised new dam proposed for the upper reaches of the Logan River to help support burgeoning population growth in south east Queensland
"As part of this process we will re-examine the existing proposal for the Wyaralong Dam site as compared to a new site which has been identified at TilleysBridge near Rathdowney. A detailed investigation, including geotechnical works will be carried out to determine which site will deliver the best yield.
"On the FitzroyRiver in Central Queensland we will raise the Eden Bann weir and build a new weir at Rookwood.
"These two projects alone are expected to deliver up to 86,000 megalitres per annum for future growth in Rockhampton, Yeppoon and Gladstone as well as help fuel our booming coal export and minerals industries."
Ms Bligh said $300 million from the Queensland Future Growth Fund would be allocated to support the continued sustainable development of clean coal technology.
"The rapid shifts in our climate are a clear warning Queensland must work to actively manage our strong position in the global economy while at the same time minimising the impact on the environment," Ms Bligh said.
"Already our Government is involved in a world leading program of research, development and promotion of alternative energy sources.
"We are focused on ensuring our levels of greenhouse gas emissions are kept to an absolute minimum while still meeting the growing demand for energy from our booming economy and population.
"Under the Fund we will allocate $300 million to help this program take a giant leap forward.
"The money will be dedicated to the future development of clean coal technology.
"It will complement a $300 million industry fund set up by consortium Coal21 which includes BHP Billition, Rio Tinto, XStrata and Anglo as well the $500 million Low Emission Technology Demonstration Fund established by the Commonwealth Government.
"We will work together on clean coal technology that will help guarantee the viability of the coal industry into the future while cutting pollution and emissions associated for the use of this resource in power generation."
Ms Bligh said other projects in the Fund would be determined once the sale process had been completed, however sufficient proceeds would be reinvested in GOC commercial infrastructure projects to ensure the State suffers no net loss of the income presently derived from the two assets.
She said that while other States had applied the proceeds of similar sales to paying off debt, the Government's history of prudent financial management and unique net debt position meant it was able to invest the funds in the future growth of the State.

Miriam Vale Toadbusters
Year 2/3 Toadbusters – We did it!!
(Kathryn Apel)
The Year 2/3 Toadbusters night was a resounding success. Conservative estimates put the number of toads 'froze' at 1000.
After a social sausage sizzle, the Year 2/3 students made an entertaining and informative rendition of the poem, ‘Bufo Marinus – What Is It?’ A superb effort!
We then welcomed Anna Hitchcock who joined us from the Gladstone Toadbusters group. Anna shared her expertise - and a lot of safety equipment. She also bagged quite a few Bufos!
The competitive side of the evening was fraught with difficulties, but this didn’t dint enthusiasm. The Browning/Lavia team bagged the ‘Loads of Toads’ award, producing 9 bags full! ‘ Catch of the Day’ was also awarded to this group – mainly because other competitors were reluctant to delve into bags and produce their whoppers. All in fun! Michelle Dahl convincingly won the ‘Warts and Wails’ award for the most shrieks and squeaks.
Though parental expectations for a ‘fun’ night perhaps weren’t that high, wide smiles and shared laughter confirmed the success of the evening. A huge thank-you to all families who turned up in support! Thanks also to Paul and Felix for wielding the BBQ tongs so proficiently.

The Ten Thousandth Toad!
These are pictures of the ten thousandth (10 000) toad caught at the Duckponds. It has taken Toadbusters five years and many volunteer hours to reach this amazing total. This little star has gone to the big duckpond in the sky like his 9 999 friends.
