RO Membrane AK Series – Màng RO Veolia (Suez)

A reverse osmosis membrane is also used for processing desalted and/or Ultra Pure Water (UPW) for various industrial and other uses, such as making up water from power plants, manufacturing of electronic chips, food industry, pharmaceutical, medical, and others. An Vi Group is a proud supplier of high quality membranes from top-rated reverse osmosis membrane manufacturing brands such as Dupont/Dow Filmtec, Nitto Denko Hydranautics, Veolia (Suez), Veolia (Suez), LG Chem H2O, Aquaporin… These membranes come in sizes ranging from 4″, and 8″ for brackish water and seawater applications. An Vi Group introduces to customers RO membrane Veolia (Suez) AK Series designed and manufactured by Veolia (Suez). This type of Reverse osmosis plant managers and operators dealing with controlled-pre-treatment waters and seeking advanced membrane treatment with good water purity. 1. General Information about Veolia (Suez) AK Series RO membrane: The AK Series of thin-film reverse osmosis (RO) elements provide high performance in brackish water applications, helping customers balance low energy consumption with high rejection requirements. Veolia optimizes chemistry and manufacturing advancements to enhance the performance of AK Series elements throughout their lifespan. Unlike the ultra-low energy AK H Series, the AK Series elements help control flux in applications with a higher risk of fouling, such as those using surface water sources. All AK Series elements carry NSF/ANSI/CAN 61 certification. 2.

General Information about operating for Veolia (Suez) RO elements: Please consult the latest Veolia (Suez) technical bulletin, design guidelines, computer design program, or call an application specialist for the recommended design range. Not strictly following the operating limits stated in this bulletin will void and nullify the Limited Warranty. The manufacturer wet-tests all RO elements and treats them with a 1 percent by weight sodium bisulfite storage solution. After the treatment, they vacuum-pack the RO elements in oxygen barrier bags or treat them with a tested feed water solution before vacuum-sealing them in oxygen barrier bags with a deoxidant inside. Veolia (Suez) advises flushing Veolia (Suez) RO elements for 30 to 60 minutes every two days using sufficient quality flushing water, such as pre-treated feed water, to prevent biological growth during system shutdown. Please consult the Veolia (Suez) RO Handling Manual for recommended flushing water quality. The presence of free chlorine and other oxidizing agents under certain conditions, such as heavy metals that act as oxidation catalysts in the feed water, will cause unexpected oxidation of the membrane. Veolia (Suez) strongly recommends removing these oxidizing agents contained in feed water before operating the RO system. Permeate from the first hour of operation shall be discarded. The customer is fully responsible for the effects of chemicals that are incompatible with the elements. Maximum operating pressure will vary depending on feed temperature.
