The ULP-4040\u00a0 is identified as a high-rejection reverse osmosis membrane element for brackish water treatment. The supplied specifications state a permeate flow of 2,600 GPD (9.8 m\u00b3\/day), 99.0% salt rejection, and 98.5% minimum rejection under test conditions of 500 ppm NaCl, 100 psi applied pressure, 25\u00b0C, 15% permeate recovery, and pH 7.5. Actual performance depends on feedwater composition, temperature, pressure, recovery, and system configuration.<\/p>\n
For industrial water treatment solutions, this membrane element may be evaluated for brackish water desalination, process water preparation, and RO system maintenance. Before purchasing, buyers should verify whether 4040 is the correct model, confirm the manufacturer’s performance datasheet, and check dimensions and pressure-vessel requirements. NSF’s listing includes 4040 as a 4 \u00d7 40-inch RO element, but the exact performance figures provided should be confirmed against the corresponding manufacturer’s documentation.<\/p>","protected":false},"excerpt":{"rendered":"
