Product catalog summary
Overview: The document provides detailed specifications and guidelines for the X-Flow Compact 27G ultrafiltration membrane, designed for applications such as effluent treatment and membrane bioreactors.
Element Specifications: The membrane has a hydraulic diameter of 8.0 mm, a membrane area of 27 m², and a module length of 3000 mm. It is constructed from polyvinylidene fluoride on a composite polyester carrier, offering high performance and anti-fouling properties.
Operating Specifications: The membrane can handle a maximum feed and permeate pressure of 1250 kPa and a temperature range of -20 to +70 °C. It is crucial to avoid sudden temperature changes to prevent mechanical damage.
Solvent and Chemical Resistance: The membrane is resistant to acids (pH >2), bases (pH <11), aliphatic alcohols, hydrocarbons, and oils. It is not resistant to organic esters, ketones, ethers, and polar organic solvents. Cleaning agents include NaOCl, H2O2, NaOH, and various acids, with specific pH and concentration limits.
Storage Guidelines: Membrane modules should be stored in a dry, ventilated area between 0 and 40 °C, avoiding freezing temperatures. After use, membranes must remain wet and treated with biocides to prevent biological growth.
Technical Specifications: The membrane features a mean pore size of 30 nm and is designed for hydrophilic tubular applications. The document emphasizes the importance of adhering to specified cleaning and storage procedures to maintain membrane performance.
Quality Assurance: The product is ISO 9001 certified, and while guidelines are provided, no guarantee of final product performance is implied due to varying usage conditions.

X-FLOW COMPACT 27G ULTRAFILTRATION MEMBRANE MEMBRANE ELEMENT DATASHEET 8 INCH 8.0 MM Compact 27G ARTICLE CODE : 7781KPC99R GENERAL SOLVENT RESISTANCE CLEANING CHEMICAL RESISTANCE • Effluent treatment Since the resistance of the membrane to solvents strongly depends on the actual process conditions, the indications given below should only be considered as guidelines. Depending on the nature of the feed solution the following cleaning agents can be chosen: • Membrane bioreactor Acids, pH >2 Bases, pH <11 Organic esters, ketones, ethers Aliphatic alcohols Aliphatic hydrocarbons Halogenated hydrocarbons Aromatic hydrocarbons Polar organic solvents Oils Sodium Hypochlorite - Typical 200 ppm, at ≤ 40 ºC - Maximum 500 ppm - 250.000 ppm hours cumulative at 30 ºC ELEMENT SPECIFICATIONS NaOCl (active chlorine) H2O2 NaOH Nitric acid Phosphoric acid EDTA Citric acid Enzymatic compounds It is recommended to keep the pH between 1 and 11 and not to exceed a temperature of 40 °C during cleaning and/or disinfection. If those standard cleaning techniques fail to remove the foulants, more concentrated cleaning solutions can be tried. Please contact X-Flow for recommendations. It has to be stressed, however, that no warranty can be given on the efficiency of any cleaning nor on the membrane performance after such cleaning attempts. Hydraulic membrane diameter [mm] For connection specifications please check the corresponding connection configuration data sheet. ADVANCED FILTR

X-FLOW COMPACT 27G ULTRAFILTRATION MEMBRANE MEMBRANE ELEMENT DATASHEET MEMBRANE CHARACTERISTICS OPERATING SPECIFICATIONS Feedpermeate differential pressure • To avoid mechanical damage, do not subject the membrane module or element to sudden temperature changes, particularly decreasings. Do not exceed 70 °C process temperature. Bring the module or element back to ambient operating temperature slowly (typical value 1 °C/ min). Failure to adhere to this guideline can result in irreparable damage • Hydrophilic tubular polyvinylidene fluoride membrane cast on a composite polyester/polyolefine carrier...

X-FLOW COMPACT 27G ULTRAFILTRATION MEMBRANE MEMBRANE ELEMENT DATASHEET STORAGE New membrane modules can be stored as supplied. Membrane modules should be stored in a dry, normally ventilated place, away from sources of heat, ignition and direct sunlight. Store between 0 and 40 °C. The membrane modules should not be subjected to any freezing temperatures. After use, UF membranes need to be stored wet at all times. To avoid biological growth during shutdowns or storage, wet membranes should be treated with a compatible biocide. The membrane is compatible with many common disinfecting agents or...
