ROTREAT, the original · Industrial membrane treatment · Austria
Robust water treatment systems for streams conventional plants cannot handle.
ROTREAT designs, builds and supports modular membrane systems for landfill leachate, industrial wastewater, high-pressure reverse osmosis and compact biological treatment.
Project logic
From raw water data to a maintainable treatment plant.
Water analysis
Feed parameters, flow rate, limits and operating constraints are translated into a treatment concept.
Pilot or design basis
Pilot testing and process modelling define recovery, membrane selection and cleaning strategy.
Containerized plant
Pre-treatment, RCDT, MBR, polishing and automation are integrated into a practical plant layout.
Operation support
Service, membrane replacement, troubleshooting and optimization keep performance stable over time.
Core technologies
Two membrane platforms. One engineering team.
RTS focuses the page around the technical decision: use the right membrane platform for the water, not a standard package forced onto every stream.
Module view
Open channel module design for difficult feed waters.
Disc tube reverse osmosis
RCDT technology
Open radial flow channels, service-friendly module design and high feed-water tolerance for landfill leachate and industrial concentrate streams.
