MRO-4H Series Industrial Reverse Osmosis Systems
Designed for larger commercial and industrial applications requiring high purity water (98-99% salt rejection). Nominal output capacities of 10,800-28,800 GPD. Horizontally arranged membrane housings for maximum product output with the minimal smallest floor-space requirements.
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.
