Sumo can be rented and run from the Cloud

January 30, 2024


Dynamita is happy to introduce a new service to help clients who would typically use Sumo intermittently, while an annual subscription is beyond their budget. From now on, premiering in the market, it is possible to rent Sumo on a weekly basis, as a cloud-based software: Sumo for Rent.

This new service is not only flexible in terms of subscription length, but also offers platform-independence: you can run Sumo on any device that has a browser and Internet connection (even your cell phone). No need for software installation and license activation: just sign up, receive a password and you're ready to go! For further details about Sumo for Rent, please check out the Products page.

Katie will be in charge of our administrative service, and you may be in contact with her for licences requests, quotes and invoices. Katie comes from New Zealand, but couldn't resist the charm of France, where she lives now.

The group photo from our latest meeting revealed a new friendly face in the team, and that's not without a reason. Let us introduce you Sabrina Wang, holding a Master’s degree in Environmental Engineering from the National University of Singapore. She has earned valuable experience in the water/wastewater industry from China, Singapore and Canada. Currently she is based in the UK, from where she is joining our growing engineering team. She will be dedicated to software innovations, applications, and outstanding support to our clients.

Team gathers in France, releasing Sumo 22.1

May 02, 2023

Dynamita folks reunited in SW France during the last week of April. It was great to meet each other again and greet our soon-to-be colleague, Sabrina (announcement to come later). Lots of fun, great food, some kayaking on the Lake of Arjuzanx, a lovely stroll in Bordeaux and crawling atop the great sand dune of Pilat made sure we don't get stranded behind our computers, still we made good progress work-wise as well.

As a result of that, Sumo 22.1 became available for download. For details about the changes in this release, please check out the What’s new in Sumo 22.1 document. This install will replace your existing 22.0 but can coexist with earlier versions (21, 19).

Sumo in Africa

February 04, 2023

After the first ever and best ever WRRmod conference in Africa in Cape Town, and recognizing the challenges African universities and startups face, Dynamita is pleased to announce the following support package:

To any university accredited and located in Africa - we are pleased to provide free unlimited perpetual licenses for the Sumo process simulation package including Digital Twin capabilities.

Any one- or two-person startup from Africa can claim a one year license of Sumo free of charge in their first year of operation.

This program will stand (at least) for the next ten years, until 2033.

Our hope is that this will result in cleaner environment and less bottled water in Africa. Free and Open source!

Dynamita at WRRmod2022+

January 17, 2023

WRRmod2022+ is soon to start in Stellenbosch, South Africa. We are proud platinum sponsors of this event and wish all participants to enjoy and benefit from the interesting programme. Dynamita is going to be represented in person by Daniel, Dwight and Imre - feel free to have a chat with us at the conference venue.

Greetings from Dynamita team

December 13, 2022

As 2022 is slowly coming to an end, the Sumo mascot gets cheeky forming snow angels, while the Dynamita Team is preparing to take a refreshing break as well, wishing you Happy Holidays and a delightful 2023.

Stay tuned, we are about to come back with exciting new developments early next year!

Sumo 22 released

October 1st, 2022

We have great news for those who have been eagerly anticipating the release of Sumo 22! Several months of ambitious development by the entire Dynamita Team brought a range of exciting new features to the package (for details, please check out the What’s new in Sumo 22 document). Now it’s your turn: download , install and experience the latest advancements in wastewater process modeling!

And last but not least, let us also invite you to the new Dynamita Sumo Wiki , the home of the complete and continuously updated documentation about Sumo.

Good news from Finland

September 29, 2022

"Hi Imre,

Many thanks for the licenses! We had a good course and all participants got their plant models done even though they’ve never used Sumo before. Some were so advanced that they even started optimizing their processes 😊 I have used another process modeling programme on the same course before, but must say Sumo’s UI is so much more intuitive that I very much prefer that.

Majia Sihvonen, Ramboll, Finland."

Sumo22 first training session

September 26, 2022

Wastewater process engineers get trained in Sumo22 at our next training session!

This will be the first training introducing Sumo22, a good way to get a head start 😊 A lot of exciting new features and process models. Learn to dynamically model alpha for better aeration design, predict N2O using our greenhouse model, predict sludge dredging in lagoons, perform carbon footprint calculations, develop blower and pump curves, and perform comprehensive energy & cost-saving simulations. And let us not forget to set up a Digital twin and perform urban watershed modeling!

Those interested please check the training flyer for the exact schedule and sign up for the event.

We are looking forward to meet you!

New member joins the Dynamita team, welcome Hung!

June 3, 2021

Hung Bui Quoc is a young talent from Vietnam, with a background in water and wastewater treatment, together with some modelling. He obtained his Master of Science in Environmental Engineering at Technical University of Munich in 2020. Hung has shown his big interest towards modelling and Sumo, so it is our pleasure to welcome him as an intern at the Dynamita team.

Hung already provided us valuable experience as a new Sumo user, so that we could improve Sumo 21 before its official release. He will also help us in Sumo translation into Vietnamese (hopefully he still remembers some Vietnamese!), weather data collection, Sumo models testing...etc. As a young graduate, we hope that the internship time with us will help Hung gain useful experience for his career development.

Sumo 21 released along with new website

May 31, 2021

The new edition of Sumo is here, packed with numerous exciting new features and innovation (for details, please see the What’s new in Sumo 21 document). We had lots of fun developing the newest reference point of wastewater process modeling, so don't hesitate and check out Sumo 21 for yourself. Bet you'll love it!

And by the way, we have a new webpage, too.

Dynamita among top environmental startups in France

April 27, 2021

Feedback for Sumo Training in April!

April 14, 2021

We had the pleasure of providing the first training with the new and shiny SUMO 21, which is very close to officially take wings and bring new dimensions to the process modeling community.

Let us share some of the feedback we received from the participants:

  • “I want to thank you and Dynamita for an excellent training program! Choke full of great info…”
  • “The training is really fantastic, which includes volume knowledge requiring deeper digestion in the following days…”
  • “Dynamita’s openness is fantastic, I am confident we made the right choice to come onboard.”

Opinions like these inspire us to push the limits further…

Sumo Training from 5th April, 2021

March 2, 2021

We'll have an interactive online training coming up in April, see the detailed program here .

Dynamita is growing, an exciting day for us, Dwight Houweling is joining our troops!

January 28, 2021

Dwight Houweling is joining our troops to help roll out our more and more innovative software solutions (Sumo, Digital Twin, Industrial Process Water Simulation, Operator interface, etc.) and help us provide the outstanding support our clients are used to. I know Dwight for a long time, well before I was a Sumo fighter - and he did quite a circle and collected a wealth of experiences around the world.

We're excited and welcome Dwight into our growing and talented group. Looking forward to finally bring the team together again, maybe this fall, not only on Zoom...

Season's Greetings

December 18, 2020

2020 brought many challenges to everyone's lives. Nevertheless, we were happy to see the Dynamita team grow and strongly hope that the upcoming year will allow all of us to get together more frequently outside of cyberspace as well. Until then, stay safe and have a blessed festive season!
