POLISHING RO ELEMENT 8040 HRX-NYVP

Summary

Product identification

KMS FOOD & DAIRY POLISHING RO ELEMENTS are Reverse Osmosis 8” Sanitary Element Series.

• Membrane Chemistry: Proprietary TFC™ polyamide
• Membrane Type: HRX™ - high rejection reverse osmosis
• Construction: Sanitary spiral wound elements with net outerwrap and attached ATD’s
• Regulatory Status: Compliant with US FDA CFR Title 21, EC Reg. No. 1935/2004, and EU Reg. No. 10/2011. Halal-certified by the Islamic Food and Nutrition Council of America (IFANCA).
• Membrane Characteristics: HRX™ reverse osmosis elements are selected when high rejection to organic and inorganic material is the objective.

Nominal Performance

• Part Number: 8882250
• Model: 8040 HRX-NYVP
• Active Membrane Area: 371 ft² (34.5 m²)
• Feed Spacer: 31 mil (0.8 mm)

Operating limits

• Maximum Operating Pressure: 650 psi (44.8 bar)
• Maximum Pressure During Cleaning: 150 psi (10.3 bar)
• Operating Temperature Range: 40-122°F (5-50°C)
• Maximum Cleaning Temperature: 122°F (50°C)
• pH Range - Continuous Operation: 4.0-10.0
• pH Range - Clean-In-Place (CIP): 1.8-11.0
• Design Pressure Drop Per Element: 3-6 psi (0.2-0.4 bar)
• Design Pressure Drop Per Vessel: 15-35 psi (1.0-2.4 bar)
• Permeate Pressure: Should not exceed baseline (concentrate) pressure at any time (including online, off-line and during transition). Reverse pressure will damage the module.
• Differential Pressure: Maximum differential pressure limit is 6 psi (0.4 bar) per element. Maximum differential pressure for any length vessel is 35 psi (2.4 bar).

Feed water

• Maximum feed turbidity: 1 NTU
• Maximum feed Silt Density Index (SDI 15-minute test): 5.0
• Chlorine and Chemical Tolerance: KMS recommends removing residual free chlorine prior to membrane exposure to prevent premature membrane failure. Sodium metabisulfite (without catalysts such as cobalt) is the preferred chemical to eliminate free chlorine or similar oxidizers in the feed.
• Cationic Polymers and Surfactants: HRX membranes may be irreversibly fouled if exposed to cationic (positively charged) polymers or surfactants. Exposure to these chemicals during operation or cleaning is not recommended and will void the warranty.

Mechanical / hydraulic

Nominal Dimensions

• Model: 8040 HRX-NYVP
• Length (A)*: 40.0 inches (1,016 mm)
• Diameter (B): 7.9 inches (201 mm)
• Internal Diameter (C): 1.125 inches (28.6 mm)

* Including two integral anti-telescoping-devices (ATD’s).

Installation Lubricants

For element installation, use only water or glycerin to lubricate seals. The use of petroleum or vegetable-based oils or solvents may damage the element and will void the warranty.
