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 operations, with a pressure rise/fall rate ≤ 0.07MPa/s.
③ The inlet SDI value must be below 5.0.
④ It is strictly prohibited for grease to enter the reverse osmosis system.
⑤ Higher pressure on the product side than on the feed water side can cause physical damage to the membrane, so back pressure on the product side of the membrane element must 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 element 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 liquid to prevent microbial growth. The standard preservation liquid 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 assume warranty responsibility.
⑤ Due to the inability to control the user's methods and conditions of use, Aidemans Company does not assume responsibility for the consequences caused by the use of the information and data in this sample, nor for the guarantee of 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 whether it is suitable for their specific purposes.
⑥ Due to technical improvements and product updates, technical data may change at any time without prior notice.
