ROGA-4040-HR 4"

Summary

Product identification

ROGA®-HR 4” Elements are Cellulose Acetate RO Elements.

• Membrane Chemistry: Proprietary ROGA® cellulose acetate
• Membrane Type: ROGA®-HR membrane
• Construction: Spiral wound with fiberglass outerwrap
• Applications: High rejection for municipal water treatment, municipal wastewater reclamation, industrial water supply, and where chlorine is needed on a regular basis

Specifications

The specifications for the ROGA-4040-HR model are:

• Part Number: 8422100
• Model: ROGA-4040-HR
• Permeate Flow: 1,700 gpd (6.4 m³/d)
• Chloride Rejection: 98.0 percent
• Active Membrane Area: 80 ft² (7.4 m²)
• Feed Spacer: 31 mil (0.8 mm)

Test Conditions: 2,000 mg/l NaCl solution at 420 psi (2,900 kPa) applied pressure, 15% recovery, 77°F (25°C) and pH 5.7.

Performance Note: Individual element permeate flows may vary +15/-15% from the nominal values. Minimum chloride ion rejection is 97% under the stated test conditions.

Operating limits

• Typical Operating Pressure: 420 psi (2,900 kPa)
• Maximum Operating Pressure: 600 psi (4,140 kPa)
• Maximum Operating Temperature: 104°F (40°C)
• Maximum Cleaning Temperature: 104°F (40°C)
• Maximum Continuous Free Chlorine: 1 mg/l free chlorine equivalent (or similarly active oxidizing agents such as iodine, bromine, and ozone)
• Allowable pH – Continuous Operation: 4 - 6
• Allowable pH – Short Term Cleaning: 2.5 - 7 (recommended to limit exposure to 4 hours, once per month)
• Permeate Pressure: Should not exceed feed-concentrate pressure by more than 5 psi (34 kPa) at any time.
• Maximum Differential Pressure per Element: 10 psi (69 kPa)
• Maximum Differential Pressure Per Vessel: 60 psi (414 kPa)
• Maximum Feed Turbidity: 1 NTU (Feedwater with turbidity greater than 0.2 NTU generally results in frequent cleanings.)
• Maximum Feed SDI (15 minute test): 5.0
• Recovery: Maximum recovery is site and application specific. Single element recovery is approximately 15%.

Feed water

• pH Adjustment: Feedwater pH should be adjusted to a practical value of approximately 5.7 to minimize membrane hydrolysis. Above pH 6, these effects may become significant and may reduce the effective life of a membrane.
• Feed Spacers: The use of 31 mil thick feed spacers (standard construction) is recommended for applications where the feedwater has higher fouling potential.

Mechanical / hydraulic

• Model: ROGA 4040-HR
• Length (A): 40 inches (1,016 mm)
• Diameter (B): 4 inches (101.6 mm)
• Center Tube Diameter (C): 0.625 inches (15.9 mm)
• Weight: 10 lbs (4.5 kg)
• Interconnector Part Number: 0035262
• O-ring Part Number: 0035468
• Brine Seal Part Number: 0035702

Lubricants

For element loading, use only the recommended silicone lubricant (or approved equivalent), water, or glycerin to lubricate O-rings and brine seals. The use of petroleum-based lubricants or vegetable-based oils may damage the element and void the warranty.
