MRO-8H High Efficiency Industrial Reverse Osmosis Systems (25-500 GPM)

Industrial & Ultrapure Reverse Osmosis Sizing Calculator

MRO-8H-SystemNECO’s Reverse Osmosis System is designed ultimate water and energy efficiency for the most demanding industrial and ultra high-purity applications requiring ultra high water quality (98-99% salt rejection). Catalogue nominal output capacities of 36,000-720,000 GPD (25-500 GPM). Specially engineered skids can be designed unto 800 gpm and can be customized to meet any engineering specifications or tight foot print. Multiple RO skids can be used to achieve high flow rate RO Systems.   SDI, Portable DI (deionization) Exchange Tank Systems can be added after the RO system to change it from a high-purity to an ultra high-purity water system. For larger applications such as power and petrochemical plants or other heavy use, high-puirty water industrial plants, an onsite regeneration based industrial mixed deionization system or electrodeionization (EDI) system can be added as a polisher and may be more cost effective than SDI.

Standard 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.
