Vontron Low Pressure Industrial RO Membrane LP21-4040 for Reverse Osmosis System
Brief Introduction
The LP (low pressure) series of aromatic polyamide compound membrane element developed by Vontron Technology Co., Ltd. has the properties of low-pressure operation, high permeate flow and excellent desalination and are applicable to desalination of brackish water. Besides, it is particularly applicable to fabrication of high-purity water for 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., LP series is mainly applicable to treatment of various industrial water such as industrial-purpose pure water, boiler water replenishment in power plant, and can be also applied to such brackish water applications as treatment of high-concentrated saline wastewater and production of beverage-purpose water.

Complete Series of VONTRONTM Dry Membrane Elements

Vontron Technology Co., Ltd. is capable of supplying complete series of dry-type membrane elements.
Compared with wet-type membrane elements, the dry-type elements have the advantages of easier transportation and installation as well as longer terms of preservation. Complete series of membrane elements are available in both dry type and wet type from Vontron technology Co., Ltd.
  Comparison between Dry-type and Wet-type Membrane Elements
 
Items of ComparisonDry-type ElementWet-type Element
Preservative SolutionNot required 1.0%(W) sodium hydrogen sulfite required as preservative solution, which shall be replaced after 90 days of storage.
Preservative Temperature
 		Not higher than 45ºC
 		0ºC~45ºC
 
Breeding of MicrobeFree from breeding of any microbeProne to breeding of microbes (in case the preservative solution is not replaced in time)
Transportation, etc.Easier for transportation thanks to light weight, thus decreasing the delivery costs.Not easy for transportation owing to heavy weight of preservative solution, thus increasing the delivery costs.

Precautions for Use of Dry-type Membrane Elements
 Storage of Dry-type Membrane Elements
1. The membrane elements must be stored in cool and dry place, and shall not be exposed to direct sunlight.
2. The dry-type elements shall be stored in the place with temperature not higher than 45, below which temperature the elements can be stored for unlimited period.
 General Information of Dry-type Membrane Elements
1. The dry-type membrane elements shall be always kept in wet condition once been moistened.
2. Only after being operated for at least 6 hours can the dry-type membrane elements be disinfected with formaldehyde.

3. The dry-type membrane elements work under the Operating Limits and Conditions and design guide identical to the wet-type elements of same specifications.
4. Once a dry-type membrane element is moistened to become a wet-type element, it shall be disposed of according to the methods of storage, preservation and cleaning indicated in this Manual corresponding to equivalent wet-type membrane element.
5.The initial adjustment and running of RO system shall be conducted in accordance with the procedures indicated in "Chapter 4 - Operation and Maintenance of RO System", and the filtered water and rejected water produced in the first one hour shall be discarded.
