One of the key parameters in Fluidized Bed reactors is the control of biofilm thickness and
configuration. The effect of upflow velocity on performance and biofilm characteristics of an
Anaerobic Fluidized Bed Reactor was studied in treating Currant wastewater at various
loading rates. The reactor used this study was made of a plexiglass column being 60 mm
diameter, 140 cm height, and a volume of 3.95 L. The results demonstrated that the AFBR
system is capable of handling an exceptionally high organic loading rate. At organic loading
rates of 9.4 to 24.2 (kg COD m−3) at steady state, reactor performances with upflow velocities
of 0.5, 0.75 and 1 (m min−1) were 89.3- 63.4, 96.9 – 79.6 and 95 – 73.4 percent, respectively.
The average biomass concentration per unit volume of the AFBR (as gVSSatt L−1 expended
bed) decreased with the increase of upflow velocity in the range of 0.5–1 m min−1 at all
applied organic loading rates. The total biomass in the reactor increased with increases in the
organic loading rate. The peak biomass concentration per unit volume (as gVSSatt L−1
expended bed) was observed at the bottom part of the reactor, then it droped off slowly
towards the top. The biofilm thickness increased from the bottom to the top of the reactor
representing a stratification of the media in the AFBR. The bed porosity increased from the
bottom to the top of the reactor.

The Congress Reporting Form
How many volunteers were present at the Congress? : More than 50
Delegates from which countries presented in the congress? : There were delegates and speakers from Many countries around the world like: United states of America, Germany, New Zealand, Japan, India, China, Thailand, Tanzania, Singapore, and Ethiopia…
Were the delegates of any other organizations present in the congress? : No
If yes, please write the names of the organizations in the box :  
What were the responses to your talking points? Were specific questions or concerns raised? : All of researches presentation was oral and some of the participants had questions the research. For example; one of them asked me about performance Anaerobic Fluidized BedReactor (AFBR) in treating high-strength wastewater
If you met staff members, please list their full names & positions. : no
Please inform us if there are any follow up actions we need to talk with the members of the congress : Since this conference is held each year and there are many important problems due to trating of waste water in some regions of our country, I think holding this conference in Iran would help to solve this kind of problems. There will be a chance to use opinion and proposals of experts from all over the world to solve waste water problems.
Your experiences about the travel processes(Providing ticket, accommodation,...) : It was routine for me as I go to different conference every year. But in this conference, we were taken to some villages in order to get familiar with health problems in people who were exposed to these problems, directly
Please give a briefing of your own observations and outcomes of the congress: : In 3 rd conference of the international conference on civil, structural and environmental engineering –(ACSEE),I met many experts in different fields and went to many sessions such as:
Platform session I: Biofiltration process on waste water
Platform session II: Epidemiology 
Platform Session III: Mechanical performance
Platform Session IV: green house gases
Platform Session V: kinetic modelling
The participants could talk and discuss with each other.
We discussed to have collaboration in some field of researches related to wastewater and green house gases problems in water and air pollution in the future.In this conference, we were taken to some villages in order to get familiar with health problems in people who were exposed to these problems, directly.
