EnglishWhat is EnviroSim and what does the company do?
Updated
EnviroSim Associates Ltd. is a Canadian company that develops and supports wastewater treatment plant simulation software. It was incorporated in 1990, and its offices and laboratory are located in the Hamilton Technology Centre in Flamborough, Ontario, Canada. If your work involves designing, upgrading, or optimizing municipal or industrial wastewater treatment plants, EnviroSim is relevant to you primarily through its flagship product, BioWin.
What EnviroSim makes
EnviroSim's flagship product is BioWin, described as a wastewater treatment process simulator that ties together biological, chemical, and physical process models. The core of BioWin is a proprietary biological model, supplemented by other process models such as:
- Water chemistry models for calculating pH and precipitation reactions
- Mass transfer models for oxygen modeling and other gas-liquid interactions
The BioWin model is owned, developed, and supported exclusively by EnviroSim. The company also references a related offering, BioTwin, on its site.
Who uses it and for what
EnviroSim states that its software is used by consulting engineering companies and utilities around the world for the design and optimization of wastewater treatment plants, both municipal and industrial. BioWin is positioned for designing, upgrading, and optimizing plants of all types.

Practical notes
The site lists a current version of 6.5.4.5173 and provides paths to get BioWin or update a current version. It also offers a "Renew License / Pay an Invoice" option and payment-method management, which indicates licensing is handled through the site — but the available material does not state prices or whether any access is free, so treat those as unconfirmed until you check the site directly.
If you want to evaluate fit, the most useful next step is to look at BioWin's process-model coverage against the specific plant types and problems you handle, and to ask about training and support options, since those are part of how EnviroSim works with clients.
