Sumo Training from 1st December

November 3, 2020

We’ll have an interactive online training coming up in December about modeling in practice with SUMO. For details, see the attached flyer.

Introduction to Sumo’s model development capability

November 3, 2020

Want to learn wastewater process model development? Have an interesting process and technology and you will like to develop a model? Watch 1-hour webinar on wastewater process model development in Sumo. We will introduce you to Sumo’s model development capabilities, show you how access model files, modify a biokinetic model and develop your own process technology unit.
Webcast key points-
Sumo has an open source structure and not just another black box
Accelerating innovation in process engineering and modeling
SumoSlang – an engineer focused way to write models
Two applications presented
-Biokinetic model – adding colloidal material and flocculation reaction to a model
-Process unit – developing an influent unit with defaults representing industrial wastewater

Dynamita is growing, we’re excited to have Peter and Navalona with us!

August 9, 2020

We were so busy that this announcement is a little delayed – but we’re welcoming Peter and Navalona joining us in the past few months.

Peter Photo
Péter Budai has a PhD from Budapest University of Technology and Economics, Hungary, where later he was an Assistant Professor teaching in Hungarian and English and participating in research projects in water quality, carbon footprint and virus testing in water(!) well before COVID. Peter is an excellent addition to our young and dedicated engineering team in our Budapest offices. Welcome Peter!
Navalona Photo
Navalona (Adrianavalona Harinaivo), with a Master’s degree in Software Engineering and Database is joining us from Antananarivo, Madagascar, with a wealth of experience in application development, several languages we use (C#, Python, English, French, etc.). Navalona will help us with our increasing workload and feature development in Sumo, Dynamizu and our Digital Twin Toolkit. Thanks for joining us in these uncertain times and hope to see you visiting the France HQ when the situation allows!

Quotes for 2020

January 2, 2020

Since starting #Dynamita, I had many many nice conversations with people who understand the novelty in what we’re doing in #SumoSimulator, and this brought me and the wonderful team of #Dynamita lots of enjoyment and satisfaction (while Edison is right with his 1% inspiration, 99% perspiration assessment). I have two memorable quotes as we’re stepping into 2020:

At the very beginning of the development:
“You’re taking on a gorilla”

Just recently:
“You sure put the fear of God in them”

Thanks everyone who joined us on this incredible journey into the future of process modeling.

Happy New Year!

Januar 1, 2020

I reflected last night releasing Chinese lanterns into the sky and 2020; and came to the revelation that there are four types of people – customers, future customers, people who for some unfathomable reason are using other process simulators and people whom I just like without simulation just as much as the previous three groups :)
Happy New Year to all, please contact us for your New Year’s present.
Imre and the Dynamita Team

Spontaneous email from Professor Lember, 15 minutes after installing Sumo

November 16, 2018

“Thanks, it is easy and what´s most important it is fast! :) it took 5-10 minutes to understand the logic of the model configuration, but it is really simple. And after 15 minutes the first plug and flow model was ready.”

We still have a few places left in our course, September 4-5, close to Nice. If you want to see efficient good engineering and advanced technologies, come on over. Just before: September 3rd pm – User Group Meeting and interesting, engaging discussions with Sumo users.

Another happy user

August 16, 2018

Wim Audenaert, AM-Team:

“We have worked with different simulators before, but never got a new model working so fast as SUMO does. We talk about orders of magnitude difference in time spent.”

Sumo fires up users

July 2, 2018

Dr. Joshua Boltz, after a successful model development project:
Thank you very much, Imre, for your exceptional support during the encoding and debugging process. Perhaps we now call you by your ancient name, Prometheus.

For we have been given fire!

Is it not fun to think, at least for this moment, we have a tool that no one else has created?”

Dynamita team is growing – again

November 20, 2015

Dynamita is pleased to announce that Tanush Wadhawan and Hélène Hauduc has joined our team.

Tanush and Hélène bring a wealth of modeling and wastewater process experience to the Dynamita team. Tanush has a PhD from North Dakota state University, he did his Postdoc research at DCWater where led the biosolids research team, focusing on the thermal hydrolysis and codigestion processes. Tanush has experience with high-rate processes, industrial treatment and organic nitrogen removal as well. Tanush is based in our office in Southern Ontario, Canada.

Hélène defended her PhD on ASM-type model comparison codirected by Irstea (Antony, France) and modelEAU (Université Laval, Québec, Canada) in 2010. She completed a Postdoc and was a teaching assistant in Toulouse at INSA, where she worked on physico-chemical modelling of phosphorus precipitation in municipal and industrial wastewaters. Hélène is based in our Toulouse office in France.
The whole team (Imre, Bernhard, Robert, Zsolt, Erika and Csaba) welcome Tanush and Hélène to the team.








Sumo status, August-September 2015

Sumo user’s first experience

September 2, 2013

Robert and Imre: I was able to run SUMO and in fact I did my first simulations. And, yes, within about an hour I am now able to do implement and run models on my own. This is excellent! So far, I very much like what I see! Best, Eberhard.

Strategic partnership with Biopolus

May 5, 2013

Dynamita’s main experience is in treatment of municipal and industrial wastewater in order for safe disposal into the environment. But we believe that the way ahead is energy and valuable material recovery and production(!), i.e. wastewater as a resource, and that this makes a lot of sense as the new vision in the 21st century. Surprise, surprise – there are other companies working towards the same goal. We’re pleased to find a strategic partner in Biopolus (, an innovative enterprise led by an outstanding thinker, István Kenyeres. We’re looking forward to this exciting cooperation with Biopolus.

Strategic partnership with inCTRL

May 1, 2013

Dynamita is happy to announce that in order to provide a wider range of services, we formed a strategic partnership with inCTRL, Canada, well-known specialists in instrumentation, monitoring and control. Dynamita and inCTRL will join forces in projects were Dynamita’s process model expertise and inCTRL’s instrumentation and control background will lead to the best model driven solutions for enhancing the control capabilities and ultimately the performance of utilities at the best possible cost/benefit ratio.

Skype call, CH2MHill – Dynamita

[1/13/2013 7:56:45 PM] Bruce Johnson: boy imre… pretty slow…  9 seconds a day for a fully dynamic feed and 72 bioreactors split into 4 parallel trains.  Can’t you do any better than that? :O

[1/13/2013 8:00:21 PM] Imre Takacs: give me heart attacks!

[1/13/2013 8:00:35 PM] Bruce Johnson: LOL!!!!

[1/13/2013 8:00:49 PM] Bruce Johnson: very sweet imre

[1/13/2013 8:02:05 PM] Imre Takacs: great. I am going to relay this to the guys because they heard so much about speed from me, they are totally fed up

[1/13/2013 8:04:01 PM] Bruce Johnson: please do!  this is absolutely incredible how quick it is.

The model has 105 state variables including DO modelling.
