Description
Vontron Reverse Osmosis Membrane ULP21-2540
The LP (low pressure) series of aromatic polyamide compound membrane elements developed by Vontron Technology Co., Ltd. has the properties of low-pressure operation, high permeate flow, and excellent desalination and is applicable to the desalination of brackish water. Besides, it is particularly applicable to the fabrication of high-purity water for the electronic industry and electric power industry owing to its excellent performance in removing soluble salts, TOC, SiO2, etc. Being suitable for desalting such water sources as surface water, underground water, tap water, and municipal water, etc., the LP series is mainly applicable to the treatment of various industrial water such as industrial-purpose pure water, boiler water replenishment in power plants, and can be also applied to such brackish water applications, such as treatment of high-concentration saline wastewater and production of beverage-purpose water.

Important Information
1. Any specific application must be limited within the Operating Limits and Conditions. We strongly recommend you to refer to the latest edition of the technical manual and design guide prepared by Vontron Technology Co., Ltd., or consult experts proficient in membrane technology. In case the customer fails to follow the operating conditions as specified in this manual, Vontron Technology Co., Ltd. will assume no liability for all results.
2. The permeate flow listed in the table is the average value. The permeate flow of a single membrane element is within a tolerance not exceeding ±20% of the nominal value.
3. All wet-type membrane elements have been strictly tested before leaving the factory, and have been treated with the solution of 1.0% sodium hydrogen sulfite (an antifreeze solution of 10% propanetriol required in winter) for storage purposes, then sealed with a plastic bag in a vacuum, and further packed in carton boxes. In order to prevent the breeding of microbes during short-time storage, transportation, and system standby, we recommend you soak the membrane elements with the protective solution (prepared with RO filtered water) containing 1.0% sodium hydrogen sulfite
(foodstuff-purpose).
4. Discard the RO-filtered water produced during the first one hour after system start-up.
5. During storage time and run time, it is strictly prohibited to dose any chemical medicament that may be harmful to membrane elements. In case of any violation in using this kind of chemical medicament, Vontron Technology Co., Ltd. assumes no liability for any outcome incurred therefrom.
Points of Attention
1. All data and information provided in this manual have been obtained from a long-term experiment by Vontron Technology Co., Ltd. We confirm that these data and information are accurate and effective. Vontron Technology CO., Ltd. assumes no liability for any aftermath caused by the user’s failure in abiding by the conditions specified in this manual in the use or maintenance of membrane products. It is strongly recommended that the user shall strictly abide by the requirements for the design, use, and maintenance of products and keep relevant records.
