MRO-4H Energy Efficient Industrial Reverse Osmosis  Systems (7.5-20 GPM)

Industrial & Ultrapure Reverse Osmosis Sizing Calculator

MRO-4H-RO-SystemNECO’s Highly Efficient Reverse Osmosis Systems are designed for medium to larger ultra high-purity, commercial and industrial applications requiring very high quality water (98-99% salt rejection). Nominal output capacities of 10,800-28,800 GPD (7.5-20 GPM). Horizontally arranged reverse osmosis membrane housings for maximum product output with the minimal smallest floor-space requirements.  SDI or Portable DI (deionization) Exchange Tank Systems can be added to this after the RO system to change it from a high-purity to an ultra high-purity water system.

Standard Features/Benefits

  • High rejection, 4″ x 40″ thin-film composite (TFC) membrane elements in a spiral-wound configuration.
  • FRP membrane housings with PVC end-cap material (300 psig rating).
  • Stainless steel multi-stage feed pump with TEFC motor (230/460V, 3-Phase).
  • Epoxy –coated carbon steel skid/frame assembly.
  • Polypropylene pre-filter housing with 5.0-micron cartridge.
  • NEMA-4X system controller complete with operator lights and switches for simple operation. Includes pre-wired motor starter, low inlet pressure switch with alarm, and pre-treatment interlock.
  • Compact product water conductivity monitor with digital display.
  • Panel-mounted product, reject, and recycle visual flow rota-meters.
  • Panel-mounted stainless steel system pressure gauges and sampling valves.
  • PVC low pressure piping/valves and brass/stainless steel high pressure tubing and valves.
  • Automatic system inlet feed valve.
  • Automatic membrane flush cycle (after system shutdown).

Optional Equipment

  • Skid-Mount Packages – RO machines are available with the necessary pre-treatment and re-pressurization equipment mounted to a structural carbon steel skid and pre-piped/pre-wired to the fullest extent. Greatly reduces installation time and costs. Not available for 18,000-28,800 GPD models.
  • Clean-in-Place Packages – For periodic cleaning of the membrane elements to remove mineral scale and biological fouling. Includes a skid mounted and pre-wired transfer pump, batch solution tank, inlet filter housing, isolation valves, and quick disconnect cleaning ports. Recommended for 18,000-28,800 GPD models to maximize membrane life and significantly reduce operating costs.
