Theo models your whole plant — biology, chemistry and hydraulics together — and solves it fast enough to explore, not just to wait. Lay out a flowsheet, press play, and watch the entire works come to life.
Lay out a plant, press play, and Theo works through time — flow rates, effluent tables and charts updating step by step as the simulation progresses.
Point a modern AI model at Theo and it can drive the simulation, read every result, and reason about your process — ask in plain English where the phosphate went, and get a traced, quantified answer.
Concentrations, reaction rates, saturation ratios, mass balances — plotted and tabulated across the whole flowsheet, and one click from export.
Drag in reactors, clarifiers, thickeners, digesters and splitters, wire them together, and Theo keeps the underlying model consistent as you go — from a single line to a sprawling multi-train plant.
Runs natively on Windows, macOS and Linux — entirely on your own machine or in your cloud, you decide. iOS and Android clients connect to a Theo instance on your desktop or server.

Respect the rules of model building, add modern numerical methods and hardware acceleration, and a whole new range of questions becomes answerable in seconds.
No shortcuts you would regret. Full pH chemistry and multi-step nitrification stay switched on — because your plant never turns them off.
A blend of in-house experience and published, peer-reviewed models, integrated across the entire plant rather than stitched together unit by unit.
Tired of user interfaces from the 90s? So are we. Theo is clean, quick and intuitive from the first click.
Comprehensive process engineering services focused on biological treatment systems
Detailed assessments of treatment plant operations to identify improvement opportunities
Advanced simulation capabilities for informed decision-making
Specialized training programs to build your team's expertise
We'd love to discuss how we can help optimize your treatment plant
