Overview

Dynamita is a France-registered software and process-modeling company specializing in simulation tools for the water and wastewater treatment industry. Its flagship product is SUMO©, a comprehensive wastewater process simulator, and its sister product DYNAMIZU© is described by the company as the world's first dynamic water-processing simulation package, covering effluent reuse, drinking water and ultrapure water models. Both products share a user-friendly graphical interface and are built on open model and process-unit libraries coded in SumoSlang©, a concept designed with engineers in mind. The company positions itself as a specialist vendor of advanced process models, tightly integrated controllers, and a Digital Twin Toolkit. SUMO is marketed for its modern design, speed, open model source code, and support from a worldwide network of resellers and partners. DYNAMIZU connects to SUMO and can be used with Dynamita's Digital Twin offering. Beyond software sales, Dynamita provides training courses for all levels and group sizes, in person or online, in multiple languages and countries, as well as model-based consulting services including model migration, software development, custom model development, and process and energy modeling. Dynamita is registered in France and operates as an extended virtual office, with employees and contributing partners located in Europe and around the world. Public company information lists it as a company in Nice, France. Its team includes internationally renowned wastewater process specialists and IT professionals. The company serves a global customer base through direct sales, resellers, and localized representation, such as Dynamita Japan, which represents SUMO and DYNAMIZU at industry exhibitions in Tokyo. Dynamita's product roadmap and community activity are visible through regular software releases, including SUMO 24.0.1 and DYNAMIZU 26.0, and through short courses and training sessions covering topics such as activated sludge plant setup, wastewater characterization, nitrification and denitrification, PdNA and mainstream anammox, aeration modeling, solid-liquid separation, chemical phosphorus removal, EBPR, biofilm systems, SBRs, anaerobic digestion, controllers, and the Digital Twin Toolkit.

History

Dynamita is a France-registered software and process-modeling company focused on the water and wastewater treatment sector. Public company information describes it as a company in Nice, France. The company was built around the expertise of internationally renowned wastewater process specialists and IT professionals, with Imre Takács, Ph.D., serving as President. Its team operates as an extended virtual office, with employees and contributing partners located in Europe and around the world, including France, Luxembourg, and other countries. Dynamita's flagship product, SUMO©, is a comprehensive wastewater process simulator. The company describes SUMO as offering the most advanced models in the industry, with controllers tightly integrated into the base package and included in the base price, a modern design with user-friendly features, open model source code, fast performance, and outstanding support from a worldwide network. SUMO is distributed through direct downloads, resellers, and network/container license services, with versions such as SUMO 24.0.1 available. The company later introduced DYNAMIZU©, described as the world's first dynamic water package. DYNAMIZU offers libraries for effluent reuse, drinking water, and ultrapure water simulations, connects to SUMO, and can be used with Dynamita's Digital Twin (at additional cost). Like SUMO, it features a modern design, user-friendly features, and open model source code. Both SUMO and DYNAMIZU are unique on the market for their open model and process unit libraries coded in SumoSlang©, a simple-yet-powerful concept designed with engineers in mind. Dynamita also offers a Digital Twin Toolkit as an add-on, along with other add-ons such as Mobile Carrier, Sewer Network, and Densified Sludge. The company provides training courses for all levels and group sizes, in person or online, in different languages and countries. Its consulting services include model migration, software development, custom model development, and process and energy modeling. Model migration is offered free of charge: customers can send a report from another simulation package and receive an equivalent SUMO configuration, tested in steady-state. Dynamita maintains a global presence through resellers and partners. Dynamita Japan represents SUMO and DYNAMIZU at industry events such as the Sewage Works Exhibition in Tokyo. The company communicates with its community through news updates, short courses, and training sessions covering topics such as activated sludge plant setup, wastewater characterization, nitrification and denitrification, PdNA and mainstream anammox, aeration modeling, solid-liquid separation, chemical phosphorus removal, EBPR, biofilm systems, SBRs, anaerobic digestion, controllers, and the Digital Twin Toolkit. Recent software releases include SUMO 24.0.1 and DYNAMIZU 26.0.
