ACM 3

Summary

Product Identification

The TRISEP® ACM series consists of low energy brackish water RO elements, offering high solute rejection at moderately lower pressure. These are strong and durable spiral-wound elements.

• Model: TRISEP® 8040-ACM3-TSA
• Part Number: 164030841
• Membrane Type: Polyamide
• Membrane Designation: ACM3
• Feed Spacer Thickness: 34 mil
• This model features a fiberglass outer wrap, diamond-shaped feed spacers, anti-telescoping devices (ATDs) attached to the element ends, one brine seal, and one interconnector.

Performance Data

• Permeate Flow: 41.6 m³/day (11,000 GPD)
• Membrane Area: 33.9 m² (365 ft²)
• Stabilized Salt Rejection: 99.3%
• Minimum Salt Rejection: 98.8%

Test Conditions: Performance data is based on 2,000 ppm NaCl, 15.5 bar (225 psi) operating pressure, 25°C (77°F) temperature, 15% recovery, and pH 8.0 after 30 minutes of operation. Flow rates may be up to 15% below the stated values.

Operating Limits

• Maximum Operating Pressure: 41 bar (600 psi)
• Maximum Operating Temperature: 45°C (113°F)
• Cleaning pH Range: 1.0 – 12.0
• Chlorine Tolerance: < 0.1 ppm
  • Note: Pretreatment is recommended for the removal of free chlorine and other oxidizing agents to prevent damage. Oxidation damage is excluded from warranty.
• Maximum Pressure Drop:
  • 1 bar (15 psi) per element
  • 4 bar (60 psi) per housing
• Maximum SDI₁₅: 5.0
• Maximum Turbidity: 1 NTU

Mechanical / Hydraulic

• Permeate Tube Type: Female
• Model: TRISEP® 8040-ACM3-TSA
  • Element Weight: 16 kg (36 lb)
  • Dim. A (Length): 1,016 mm (40.0 inches)
  • Dim. B (Diameter): 201 mm (7.9 inches)
  • Dim. C (Inner Diameter): 38.1 mm (1.50 inches)

Important Information

• Start-up: It is recommended to flush elements for 30 minutes at low pressure and discard permeate during the flush prior to operation.
• Cleaning: Elements require periodic cleaning to maintain proper operation and prevent damage.
• Storage: Elements must be stored appropriately to ensure proper operation and prevent damage.
