Frequently Asked Questions

Common technical questions related to our engineering principles.

What makes Rototech's system design superior?

We leverage high-grade materials (like Titanium and Hastelloy), advanced scaling mitigation techniques, and energy-optimized MVR/MEE configurations to reduce OPEX significantly.

How do you manage complex, high-COD effluents?

Our custom Agitated Thin Film Dryers (ATFD) and Stripper Columns separate challenging organics, achieving up to 99% purity and True Zero Liquid Discharge (ZLD) without fouling the main evaporators.

Do you offer custom engineering for specific industries?

Absolutely. From Pharmaceuticals and Chemicals to Food & Dairy, every system is custom-designed according to the specific boiling point elevations, viscosity, and chemical nature of the feed.
