Engineering summary from PDF text extraction for BR 8040. Verify every value with the OEM datasheet.
Summary
Product identification
The Oltremare BR series consists of high rejection brackish water Reverse Osmosis (RO) elements, specifically the BR 8040 models. These spiral-wound elements are designed for water purification applications, offering very high solute rejection and are suitable for upgrading existing RO systems or new installations. They are available in standard 8" designs.
Membrane Characteristics
- Membrane Type: Polyamide RO
- Stabilized Salt Rejection: 99.5%
- Minimum Salt Rejection: 99.2%
- (Based on test conditions: 1,500 ppm NaCl, 15.5 bar (225 psi), 25°C (77°F), 15% recovery, pH 8.0, 30 minutes operation. Flow rates may be up to 15% below shown values.)
Design Information

|---|---|---|---|---|
| Oltremare BR2 – 8040 | 37.9 (10000) | 17 (75) | 34 (365) | 31 |
| Oltremare BR3 – 8040 | 41.6 (11000) | 17 (75) | 37.2 (400) | 28 |
| Oltremare BR3G – 8040 | 41.6 (11000) | 17 (75) | 37.2 (400) | 34 |
| Oltremare BR34 - 8040 | 45.4 (12000) | 17 (75) | 40.9 (440) | 28 |
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
- Pretreatment for free chlorine and other oxidizing agents is recommended to prevent damage. Oxidizing agents in contact with polyamide membranes can shorten operating life or cause membrane failure, and such damage is excluded from warranty.
- Maximum Pressure Drop: 0.7 bar (10 psi) per element; 4 bar (60 psi) per housing
- Maximum SDI₁₅: 5.0
- Maximum Turbidity: 1 NTU

- Element weight is dependent on packaging and quantity.
- Dim. C is the inner diameter for female elements.
- Female elements are supplied; male elements (not listed here) have a protruding permeate tube ("D").
Important Information
- Start-up: Flush elements for 30 minutes at low pressure and discard permeate before operation.
- Cleaning: Periodic cleaning of Oltremare membrane elements is necessary for proper operation and to prevent membrane damage. Refer to the Membrane Cleaning Guide for details.
- Storage: Appropriate storage of Oltremare membrane elements is required for proper operation and to prevent membrane damage. Refer to the Element Storage Guides for details.
