HSRO-390-FF

Summary

Product identification

FilmTec™HSRO-390-FF heat sanitizable reverse osmosis membrane element.

This element delivers outstanding quality water with the added capability to withstand sanitization with hot water, eliminating the need for chemical sanitizers. Its full-fit configuration minimizes stagnant areas, optimal for sanitary design applications. All components comply with FDA standards.

• Part Number: HSRO-390-FF (170701)

Typical Properties

• Active Area: 390 ft² (36 m²)
• Applied Pressure: 150 psig (10.3 bar)
• Stabilized Permeate Flow Rate: 9,000 gpd (34 m³/d)

Important Information

• Membranes must be kept moist at all times after initial wetting.
• To control biological growth during prolonged system shutdowns, elements should be immersed in a preservative solution.
• Avoid static permeate-backpressure at all times.
• The use of this product does not necessarily guarantee the removal of cysts and pathogens from water; effective reduction depends on complete system design, operation, and maintenance.
• Permeate obtained from the first hour of operation should be discarded.

Pre-Conditioning

New FilmTec™HSRO heat sanitizable spiral elements must be pre-conditioned prior to initial use by exposure to hot water to perform to specifications. This process requires chlorine-free, non-scaling/fouling water (RO permeate is preferred). A conditioning procedure involves:

1. Flushing to drain (~30 min) at low pressure and flow rate.
2. Recycling warm water (up to 45°C) at very low transmembrane pressure (< 25 psig (1.7 bar)) and maximum feed pressure of 45 psig (3 bar), with a maximum element pressure drop of 1.5 psig (0.1 bar).
3. Introducing hot water to increase temperature to 80°C (176°F) at a ramp rate no faster than 1-2 ºC/min (max 4ºC/min).
4. Maintaining transmembrane pressure below 25 psig (1.7 bar) when warm or hot water (45°C or higher) is fed.
5. Maintaining temperature for 60 – 90 minutes.
6. Cooling to 45°C or below at a ramp rate no faster than 1-2 ºC/min (max 4ºC/min).
7. Flushing to drain (~30 min) at very low pressure (< 25 psig (1.7 bar) transmembrane pressure with maximum feed pressure of 45 psig (3 bar)).

Note: Permeate should NOT be recycled during the FIRST heat-setting process (pre-conditioning) from step 2 to 6.

Operation Guidelines

Avoid abrupt pressure or cross-flow variations. During start-up, gradually increase feed pressure over 30-60 seconds and achieve set cross-flow velocity gradually over 15-20 seconds.
