(Practice)Standard Practice for Standardizing Ultrafiltration Permeate Flow Performance Data
Standard Practice for Standardizing Ultrafiltration Permeate Flow Performance Data
SIGNIFICANCE AND USE
5.1 During the operation of a UF system, conditions including pressure and temperature can vary, causing permeate flow to change (see Note 1). To effectively evaluate system performance, it is necessary to compare permeate flow data at the same conditions. Since data may not always be obtained at the same conditions, it is necessary to convert the UF data obtained at actual conditions to a set of constant conditions, thereby standardizing the data. The user of this practice determines the standard conditions. This practice gives the procedure to standardize UF data on pure water only.
Note 1: Feed concentration, crossflow velocity, and both device and total system recovery will also influence permeate rate, especially when operating on other than pure water. This practice does not address those system conditions.
5.2 This practice can be used for systems which contain spiral-wound, tubular, plate and frame, and hollow fiber devices.
5.3 This practice can be used for a single-element or a multi-element system. However, if the UF system is staged, standardize the permeate flow and salt passage for each stage separately. This requires pressure readings at the feed inlet and concentrate outlet of each stage.
5.4 This practice is applicable for UF systems with no significant leaks between the feed/concentrate and permeate streams.
5.5 This practice assumes no significant osmotic pressure differential (Δπ) exists in the UF system under the actual operating conditions. Differential osmotic pressure will reduce the permeate rate relative to operation on pure water.
5.6 The user of this practice should be aware that fouled UF devices will produce less permeate flow than nonfouled devices, and may wish to perform flushing, chemical, or mechanical cleaning, or combination thereof, prior to determining the permeate flow performance of the device.
SCOPE
1.1 This practice covers the standardization of permeate flow for ultrafiltration (UF) systems.
1.2 This practice is applicable to natural waters including brackish waters, seawaters, and ultrapure waters including those used in power generation and microelectronics and pharmaceuticals production. It is not necessarily applicable to waste waters.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM D5090-20 outlines the standard practice for standardizing ultrafiltration (UF) permeate flow performance data. Developed by ASTM International, this practice addresses the need to compare permeate flow from UF systems under varying operational conditions by converting performance data to a consistent, user-defined set of standard conditions. Standardization is critical for evaluating and benchmarking UF system performance, particularly when reviewing results from different devices, operational setups, or periods.
Ultrafiltration permeate flow can be affected by factors such as pressure, temperature, and system cleanliness. Standardizing this data ensures accurate performance assessment and system optimization, making ASTM D5090-20 essential for industries relying on membrane filtration for water purification.
Key Topics
Scope & Applicability:
- Applies to the standardization of permeate flow for various UF systems.
- Suitable for systems treating natural waters (brackish, seawater, ultrapure) in industries including power generation, pharmaceuticals, and microelectronics.
- Not intended for standardizing data from wastewater applications.
System Types Covered:
- Spiral-wound, tubular, plate and frame, and hollow fiber UF devices.
- Both single-element and multi-element (including staged) systems are addressed.
Operating Conditions:
- Data standardization is based on pure water testing.
- Pressure, temperature, and system recovery are considered, with standardized permeate flow calculations requiring accurate readings of these parameters.
- Assumes no significant leaks or osmotic pressure differential in the system.
- Proper cleaning and maintenance are advised for accurate permeate readings.
Standardization Process:
- User sets standard conditions for comparison.
- Calculations correct data for differences in operating pressure and temperature.
- Temperature correction factors may be provided by device suppliers or calculated as necessary.
- Staged systems require separate standardization for each stage using relevant feed and concentrate pressure data.
Applications
The application of ASTM D5090-20 brings practical value in a range of sectors by enabling:
Consistent Performance Benchmarking:
- Facilitates reliable comparisons over time, between different system designs or operational runs.
- Essential for vendors, operators, and engineers to assess membrane condition and system efficiency.
Research and Development:
- Allows membrane manufacturers and system designers to evaluate and optimize UF module designs under controlled, comparable conditions.
Process Optimization:
- Supports maintenance decisions, such as identifying membrane fouling and the effectiveness of cleaning procedures.
- Aids in troubleshooting process variations related to temperature or pressure fluctuations.
Regulatory and Quality Assurance:
- Provides validated, traceable data for audits, compliance, and quality control within regulated environments.
