About
ROTEC develops mineral scaling-prevention technologies for the water treatment industry. Its Flow Reversal (FR-RO) technology inhibits biofouling and mineral scaling on the surface of membranes and pipes by periodically reversing the flow of feed water inside the pressure vessel, ensuring that scaling does not have time to form on membrane surfaces before being swept away. This technology enables high-recovery RO without exposing plants to the hazards of scaling, helping municipal and industrial clients generate clean water, utilize less raw water, and reduce brine volumes. ROTEC is part of WFI Group (Water From Innovation Group). ROTEC was founded as a spinoff from Ben Gurion University in the Negev desert.
