ROTEC’s products benefits and advantages

Increasing process recovery rate in a steady-state operation

  • Up to 20% increase in water production.
  • Up to 20% decrease in raw water (feed) consumption.
  • Up to 70% decrease in brine (concentrate) volume for disposal.

Prohibition of Biofouling growth

  • Proven highly effective to prohibit the growth of Biofouling when compared to conventional RO.
  • Minimize Chemical Cleaning (CIP) frequency.

Minimizing chemical consumption

  • Minimize or eliminate anti-scalant and acid consumption.
  • Allowing a cost-effective combination of crystallizer systems in RO process (near ZLD).

Strong feasibility in the conservative market

  • Can be introduced to RO desalination plants, either as a retrofit (of existing installations) or as a greenfield plant design (new installations).
  • Minimal operational adjustments required (~99% of the time, Flow Reversal based systems operates the same as standard RO).
  • Fallback – 100%

4 lines of products are commercially available:

1. Ultra-High Recovery RO desalination systems

ROTEC provides a wide range of turnkey applications incorporating off-the-shelf or customized Flow Reversal desalination systems, tailored to meet specific industrial applications. Supplied system includes a complete “ROTEC System” – all the additional equipment required to allow operation at higher recoveries compared to standard system design as an integral part of the desalination system. The supplied system will also include all the required pre-treatment and post-treatment auxiliary systems.
