Reverse Osmosis

NARO WATER SOLUTIONS’ Reverse Osmosis (RO) are custom designed and made for removing dissolves solids, ions and molecules. Using a semi-permeable membrane, it eradicates over 99% of contaminants from water.

NARO offers RO capacities range from 10 up to 50,000 cubic meters per day, with skid mounted, or containerized options. The systems are preassembled and pretested prior to dispatch from the factory, which minimizes site installation works, time and cost.

RO mainly works in conjunction with other purification processes such as Pretreatments (DAF, Filtration, Ultrafiltration) and Demineralization (Mixed Bed or Electro-deionization (EDI).

NARO’s complete process solutions include the design, engineering, fabrication, supervision of installation and commissioning.
