Brief Introduction

Vontron's fouling resistant elements include FR series and PURO series.

FR (fouling resistant) series of aromatic polyamide RO membrane element developed by Vontron Technology Co., Ltd. is applicable to desalination of brackish water. It is characterized by low-pressure operation, higher water productivity and excellent desalting performance. Moreover, special treatment has been made to the surface of membrane with unique technology to change its electrical charge and smoothness, increasing the hydrophilicity of membrane surface, thus decreasing the adhesion of contamination and microbe so as to lessen the pollution and extend the service life of elements.

Newly developed by Vontron, the PURO-I is specially designed for treatment of water reclamation and surface water treatment where the water source contains high contamination. This brand-new element contains a new fouling resistant coating, and the membrane surface is treated with special technology to modify the electrical charge and smoothness of membrane surface so as to increasing the hydrophilicity of membrane surface, thus decreasing the adhesion of contamination and microbe so as to lessen the pollution and extend the service life of elements. Besides, the wider 34mil feed spacer channel can provide better fouling resistance and washability. Vontron's fouling resistant products are designed for desalting treatment of such water with salt concentration less than 10,000 ppm as surface water, underground water, tap water and municipal water, etc. It is mainly applied to treatment of various industrial water applications, such as reuse of industrial reclaimed water and boiler water replenishment for power plant, etc., and is particularly applicable to treatment of those water containing slight organic pollutants such as industrial wastewater, municipal sewage and other slightly contaminated 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.
