Precautions

① The product water from the system should be discarded one hour before the first startup;

② During startup and shutdown, excessive fluctuations in flow and pressure pose a risk of membrane element rupture. The system should gradually increase/decrease pressure and flow during startup and shutdown, with a pressure rise/fall rate ≤0.07 MPa/s;

③ The feed water SDI value must be below 5.0;

④ It is strictly prohibited for grease to enter the reverse osmosis system;

⑤ If the pressure on the product water side is higher than the feed water pressure, it can cause physical damage to the membrane, so back pressure on the product water side of the membrane element should be avoided at all times.

General Information

① Each membrane element is equipped with a concentrate sealing ring, a connection adapter, and corresponding O-rings at the time of shipment; specific contents are subject to the actual product;

② Once the component is wetted, it should always be kept moist;

③ When the system is out of service for a long time, the membrane element should be immersed in a protective solution to prevent microbial growth. The standard preservation solution contains 1.0% (weight) sodium bisulfite (food grade) and 1.0% (weight) sodium citrate (food grade);

④ Users should avoid using any chemical agents that may affect the membrane element. If such chemical agents are used, Jiangsu Aidemans Technology Co., Ltd. will not bear warranty responsibilities;

⑤ Due to the inability to control the user's methods and conditions of use, Aidemans Company does not bear any consequences arising from the use of the information and data in this sample, nor guarantees the safety and applicability of the product, whether used alone or in conjunction with other products. Users are advised to conduct tests to determine its safety and suitability for their specific purposes;

⑥ Due to technical improvements and product updates, technical data may change at any time without prior notice.

AAD-UW reverse osmosis membrane is used in the chip industry.

                

Product Features: The UW series reverse osmosis membrane elements developed for the preparation of ultra-pure water have high TOC rejection rates and low TOC leaching characteristics. The ultra-pure water produced is suitable for industries such as electronics, semiconductors, and pharmaceuticals. The design of high-flow elements reduces the cost of ultra-pure water preparation. The high-fouling-resistant UW series membrane elements are specifically designed for wastewater reuse processes in the semiconductor industry, improving water efficiency. Mainly used in the production process of ultra-pure water for chip manufacturing.
