Also very Interesting Read on Bauxsol from Recent Italian Conference.

BWO 06-27 USING SEAWATER-NEUTRALISED RED MUD (BAUXSOL™) AND BAUXSOL DERIVATIVES TO REMOVE ARSENIC FROM WATER

Significant health risks, including cancer, are associated with prolonged exposure to elevated arsenic concentrations in drinking water even at low concentrations. In view of the occurrence of arsenic in groundwaters in many countries, including several of the poorest developing countries, the development of an inexpensive and efficient system for arsenate removal from drinking water is essential. Promising sorbents have been developed from the seawater-neutralised bauxite refinery residues red mud (Bauxsol™) including acid treated Bauxsol (ATB), acid and heat treated Bauxsol (AB), Bauxsol coated sand (BCS), and AB coated sand (ABCS). Furthermore these sorbents have been tested for their ability to remove arsenic from drinking water, and reported that all these materials can be effectively used for the removal of arsenic (mainly arsenate) from water down to acceptably low concentrations. Their respective affinities towards arsenic, as well as their optimum operational conditions vary, however. The affinity of the developed sorbents towards arsenic in a decreasing order is AB > ATB > ABCS > BCS > Bauxsol, and sorptive capacity of all tested sorbents compares well with the similar unconventional sorbents, and AB, ATB and ABCS can even compete with the pure sorbents such as Fe- and Al- oxides commonly employed for the arsenic removal. This is significant as the cost of the pure sorbents that work well for arsenic removal is a limitation, and the sorbents developed in this study is cost-effective. When the affinity of commonly used adsorbents towards arsenic is compared with the sorbents developed in this study, it is found that the obtained sorptive capacity is comparable to, or better than, other available sorbents. The use of these sorbents may also produce several other benefits through simultaneous removal of a wide range of other potentially hazardous trace elements to very low concentrations without introducing any other secondary contaminants to the water. These additional benefits could be achieved at no extra cost and because the spent sorbents are not toxic, they can be disposed of without the need for confinement. Considering the fact that the raw material of the developed sorbents, red mud, is originally an industrial waste material generated in the alumina industry, the developed sorbents should be readily available and inexpensive compared to alternative materials and their use will enhance resource use efficiency.

I think we should be hearing from Trials carried out by "The Water Research Centre" Soon.
A positive outcome will be Good for VTI and open the Door to all the Water Utilities not just in the UK ;-)))

WRc works with governments and regulatory bodies to ensure soundly based regulation. It works with companies impacted by regulation, particularly the water utilities, their suppliers and the waste industry to optimise operational efficiency.

WRc independent study

Virotec has recently retained the Water Research Centre based in Swindon, United Kingdom (WRc) to independently assess the effectiveness of its ViroSewage™ reagent as a passive ViroFilter™, an end of pipe solution for the extraction of Phosphorous from municipal waste water. The company anticipates that the research will be conducted over a six month period. This is an alternative application of the active dosing ViroSewage™ technology and will enable Virotec to access a broader market with its ViroSewage™ products.

HOOTSTER - Thanks for the diligent research.

Hootster - the Water Research Centre study was announced in the shareholder update on 22/2/05 as recently entered into and which the company anticipated would last about six months. Anything in particular lead you to expect hearing from the results soon?

I would expect to get news about the expansion of the Electrobind operation in the USA following on from the Advance Plating contract first.

Extract from 22/2

Advance Plating
In the USA, Virotec recently installed a significant treatment facility (annual contract value, $AUD 65,000) into Advance Plating, a Boston, Massachusetts plating company, where, after three months of operation, ElectroBind™ has exceeded all treatment expectations. Market analysis indicates there are over 10,000 electroplating facilities in North America and, as a result, the company is currently formulating an expansion plan for North American operations. The success in North America follows a range of commercial contracts for ElectroBind™ in Australia, including metal finishers located in Melbourne and in Brisbane.

Clearly as far as VTI is concerned “recently” can mean in excess of three months.

I tried hunting the net to locate Advance Plating to see if this was an independent or one plant in a large group with many plants. This might affect how quickly follow-on contracts are won. However I could not find it – Advance Plating in Texas, Indianapolis or even Worcester MA – yes, but not in Boston. Any one else run this one down?

It's hard not to be optomistic about the WRc trials. Again from the update-

Colgate-Palmolive

After a substantial trial period in which Virotec was asked to prove the efficacy of its new ViroPhos™ reagent, Virotec has formally entered into a two year license with Colgate-Palmolive in Australia to ensure that they meet stringent requirements for the removal of Phosphorous and suspended solids from its industrial effluent. The annual contract value is $AUD 35,950.

If VTI were able to satisfy Colgate-Palmolive that they could remove phosphorus then hopefully the trials will be fruitful. OK, no doubt municipal waste water is different from industrial effluent but the ability of the VTI team to customise Bauxsol by varying the reagents seems boundless.

I wonder how many other trials are underway for other companies? It may require patience but I am looking forward to a lot more good news by the year (calendar) end.

Alan I think we could hear flash update as soon as April maybe not full results of study IMHO....

The following Snippet from the recent Shareholder update is very Interesting, now the company must know that there is a take up of this 100,000 tonnes of alumina refinery residue and if my summs are right is 450$ausd per Tonne of Bauxsol gives 45mln ausd of revenue, and if the rumours are true that there is need for further supply.
Seems to me that Co must be confident of Forward Orders ;-)))

REGARDS THE HOOT...........



North America

Virotec has entered into an arrangement for the initial supply of 100,000 tonnes of alumina refinery residue in North America. This arrangement ensures an economic source of supply of raw material suitable for BaseconTM conversion to BauxsolTM raw material for the expansion of Virotec's North American operations.

HOOTS - yes, word is that a much larger quantity is required:getting VERY exciting. The share price is ridiculously oversold imo - will become apparent
to believers and the questioning soon enough no doubt, but only when a deal is announced of course! Wouldn't be surprised also to see a major advance for VTI on all those electroplating companies.

I have not seen this document before. It is a summary by the EPA of all ARD treatments. Somewhat depressingly there are 45! Less depressingly Bauxsol seems to attract the most positive comment - or perhaps that's my shareholder's rose tinted glasses!

Virotec's licencee in the US for ElectroBind is a company called EnviroVizion. Good to see that they have already got a licencee in place.

This from EPA document at-

http://webferret.search.com/click?wf,EnviroVizion,,www.epa.gov%2Fepaoswer%2Fhazwaste%2Fgener%2Finit%2Fcomm8-04.pdf,,aol

Company -
EnviroVizion/Virotec
Program
Innovation
New Product ElectroBind is a new and proven metal sequestration technology for the plating industry developed by Virotec and licensed by EnviroVizion in
North America. Because it is prepared from an industrial by-product, it is
inexpensive and the use of the material provides an excellent example of
Green Technology?. It can be prepared as pure Bauxsol or as one of many
possible blends designed to enhance its capacity to treat contaminated
waters with different compositions.

I like that "proven" bit.
