Reverse Osmosis Systems - MRO-8H Series

The Marlo 'MRO-8H' Series Reverse Osmosis system is designed for industrial applications requiring high purity water (98-99% salt rejection).

Nominal output capacities of 36,000-432,000 GPD (25-300 GPM).
Flexible design allowing for easy customization to meet tight engineering specifications.

Features/Benefits

  • High rejection, 8" x 40" thin-film composite (TFC) membrane elements in a spiral-wound configuration.
  • FRP membrane housings with PVC end-cap material, stainless steel side-entry feed/reject ports, and white polyurethane finish. Designed for 300 psig pressure rating.
  • Stainless steel multi-stage feed pump with TEFC motor (230/460V, 3-Phase).
  • Epoxy –coated carbon steel skid/frame assembly.
  • Stainless steel pre-filter housing with 5.0-micron cartridges.
  • NEMA-4 programmable logic controller (PLC) package complete with operator lights and switches for optimal system control. Includes pre-wired motor starter, low inlet and high pump discharge pressure switches with alarms, and pre-treatment interlock.
  • Product water conductivity monitor with digital display and adjustable alarm.
  • Panel-mounted product, reject, and recycle flowmeters with digital display.
  • Panel-mounted stainless steel system pressure gauges and sampling valves.
  • In-line system temperature indicator.
  • PVC low pressure piping/valves and 304 stainless steel high pressure piping and valves.
  • Automatic system inlet feed valve.
  • Automatic membrane flush cycle (at programmed timed intervals).

Optional Equipment
