X-FLOW COMPACT 27 ULTRAFILTRATION MEMBRANE MEMBRANE ELEMENT DATASHEET 8 INCH 8.0 MM Compact 27 ARTICLE CODE : 7821KPC99R 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 FILT

X-FLOW COMPACT 27 ULTRAFILTRATION MEMBRANE MEMBRANE ELEMENT DATASHEET MEMBRANE CHARACTERISTICS OPERATING SPECIFICATIONS • • To avoid mechanical damage, do not subject the membrane module or element to sudden temperature changes, particularly decreasings. Do not exceed 60 • °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 Structure asymmetric Mean...

X-FLOW COMPACT 27 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 biocidal...
