Sydney has a similar problem. The primary treatment plants are not suitable
for the large quantities of influent. I work on a project in Queensland devoted
towards Solid waste management. Our research revolves around the
anaerobic degredation of MSW, which we initially started using raw sewage.
Another area we are looking at is the aerobic degredation of waste using
worms. I'm not sure if i have really helped you, however if you wish to find
out more, feel free to mail me.

Subject: MEASURING BIOREMEDIATION RATE OF HYDROCARBONS

Respirometer monitors bioremediation rate of hydrocarbons in soil and
water
New O2/CO2/CH4/H2S Respirometer is intended for monitoring gas exchanges
caused
by bacteria activity during aerobic or anaerobic
biodegradation/bioremediation of hydrocarbons, plastics, explosives,
fuels. It can also be used for monitoring respiration of algae, plants and
insects. Up to 80 sample chambers can be connected to Respirometer which
is equipped with O2, CO2,CH4 and H2S Analyzers. Optional H2 sensor is
also available.Sample chambers can be refreshed by ambient air or from the
compress gas bottles or from the programmable gas blender. Respirometer
is capable to measure head space gas exchanges ( oxygen consumption ,
CO2/CH4,H2S production etc) on 24h basis. Multiple experiments of
different length can be conducted in the same time using liquid or solid
samples. Due to the exceptionally high sensitivity 0.2uLof gas/h,
Respirometer can monitor very slow anaerobic biodegradation processes but
optional open flow arrangement providing air supply to the reactors can be
used to measure gas exchanges during composting or fermentation processes.

Subject: RS of Baikal lake - partnership proposition
From: "Sergey V.Semovskij"
Date: 13 Nov 1996 12:02:02 GMT
Dear colleagues,
I am going to leave my present place of work for the Baikal Region
"This is no ordinary lake. Baikal is the world's largest lake by volume,
holding 20% of all the earth's liquid fresh water! Four hundred miles
long and averaging about fifty miles wide, it is over one mile deep.
Moreover, the lake's bottom is a layer of sediment over five miles thick,
making the Baikal rift the earth's deepest non-oceanic trench."
(Text courtesy of NASA SeaWifs and Earth Island's
"http://www.earthisland.org/ei/baikal.html")
I am looking for people in the community who can have an interest in Baikal
RS studies partnership. The area of studies is (and as I know it's new for
the Baikal region) - to use satellite imagery available (CZCS, AVHRR, MOS
on IRS and "Priroda", OCTS and future SeaWiFS) for lake ecosystem studies -
three dimensional physical field and ecosystem simulation by surface data,
hydrodynamic and ecodynamic models coupling.
The possible sources of funds for cooperation can be for European - 1997
INTAS project (Russians need to have a 2-3 partners on the West to have a
support), INCO-COPERNICUS DGXII 1997 project and other possibilities.
I begin my activities now because as I know, I will have only e-mail
account in Irkutsk not such excellent Internet attempt as here in Poland.
Thank You in advance for contact
Yours
Sergey V.Semovski, Dr.
Institute of Oceanology, Sopot, Poland
