8-Inch Sea Water Desalination Element Vontron RO Membrane SW8040HR-400
Brief Introduction

SW series of aromatic polyamide compound membrane element developed by Vontron Technology Co., Ltd. is applicable to desalination of seawater. By optimizing the structure of membrane element, the SW series increases the permeate flow, and requires fewer elements for same permeate flow. It is characterized by low operating pressure, low investment in equipment, excellent rejection rate and reliable performance, and its high salt rejection can ensure producing the drinking water from seawater simply through one-pass RO design.

Applicable to treatment of seawater and high-concentration brackish water, the SW series of membrane element is designed for various industrial water treatment, such as seawater desalination, high-concentration brackish water desalting, boiler water replenishment for power plant, etc., and is also applicable to various fields such as recycling of wastewater, concentration and reclamation of such substances with high additional value as foodstuff, pharmaceuticals, etc.

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.
