 Mr. Foo:

My name is Jon Iza, and I am actually working with Prof. Mike
Switzenbaum, at the University of Massachusetts at Amherst. I got a
connexion with Bio$conv network, and we are commenting some of the
messages.
I think you know the kind of work Mike is doing here about Anaerobic
Digestion. I am a post-doc researcher for one year. I did my thesis in
Spain, about Anaerobic Fluidized bed reactors for industrial
wastewaters, and I was one year at Wageningen, with Prof. Lettinga.
Mike and I we are both members of IAWPRC (Anaerobic Digestion
Specialist Group).
We will be very happy to help you, if needed. Please, do not hesitate
to contact us for any comment or information.
Best greetings!
Jon Iza

I was disconnected for several days and I found now your messages.

I write now the information you asked:
I worked in Spain at the University of Valladolid with Prof. Polanco,
in a Pilot plant study of Fluidized Bed reactors for anaerobic
treatment of sugar beet wastewater. The reactor was 1.2 m3, 0.5 m
diameter and 7.5 m high. The system performed quite well, reaching
Organic Loading rates of 36-40 kg COD/m3 d. Some part of the study was
the hydrodynamic behaviour of the bed. You will find more information
on Anaerobic Digestion 88, Bologna proceedings.

Some more work was done on sewage treatment in anaerobic fludized bed
reactors, starting with many lab scale reactors til one pilot reactor
(7m3) which is working now. Valladolid is not a very continental
weather with lows near -10 C and highs of 40 C, so the treatment is
quite difficult.

After my PhD thesis, I went to Wageningen, working for one year at
Prof. Lettinga's lab, studying the treatment of cane vinasses at meso-
and thermophilic  conditions. Some results will be presented next
September at IAWPRC Seminar on Agro-Industries Wastewater Management.

Since last October I am here at the University of Massachusetts,
Environmental Engineering Program.

Here the research focus on Anaerobic Digestion is the Set up of Early
Warning Systems for Anaerobic reactor Upsets. This is performed by
online monitoring of gas composition. I am personally involved in a
Leachate treatment project, building a pilot plant, to
apply the Lab knowledge to on site conditions.

I hope this information will be good enough to let you know what I am
doing here.

With my best regards.

Jon Iza
