gd55光大彩票1、 Equipment name: hydantoin nanofiltration membrane element

2、 Specification and model: esna1-k1

3、 Equipment brand: heidaneng hdn

4、 Product Description:

The esna1-k1 series is a high-performance nanofiltration membrane produced by the company, which can effectively remove the hardness, iron, chroma and trichloromethane (THM) and other substances, and also can obtain high water flux under very low pressure, not only saving energy consumption, but also the related auxiliary equipment such as water pump, pipeline and pressure vessel is cheaper. 　

Industrial water, food, beverage, pharmacy, catalyst and chemical processing, electric power, municipal water, desalination, mining, hydrometallurgy, domestic and commercial water treatment.

gd55光大彩票6. Maximum inflow turbidity: 1.0ntu

gd55光大彩票7. Maximum inflow sdi15:5.0

8. Maximum inflow: 75gpm / 17m 3 / h

gd55光大彩票9. Ratio of minimum concentrated water and water yield: 5:1

10. Maximum pressure loss of single element: 10psi / 0.07pma

gd55光大彩票7、 System analysis:

1. The retention rate of the system is very stable, which makes the treatment effect of the system relatively stable.

2. In order to ensure the long-term stable operation of the system, the imported stainless steel multi-stage high core pump is used, and the driving force of the pump is very stable.

gd55光大彩票3. All kinds of imported nanofiltration membrane materials are used to maintain the stability of the automatic operation of the system.

4. The whole process of membrane separation can be controlled by online monitoring of the parameters of the system, such as temperature, pH, flow and pressure.

8、 Precautions:

The deviation range of Esna 1-k 1 water yield is generally within ± 15%, and the deviation range of effective membrane area is within ± 4%. Each module is delivered with a concentrated water seal ring, a connection adapter and a corresponding O-ring. All membrane elements are vacuum sealed in polyethylene plastic bags and added with sodium bisulfite of no more than 1.0% concentration as the protective liquid. The membrane elements under vacuum protection are finally stored in cartons.

1. The system equipment is entitled to one-year free warranty, the warranty date is calculated from the date of product acceptance, and the consumable filter material is not listed here.
2. In case of any equipment quality problem (except caused by misoperation or unforeseen factors) during the warranty period, the supplier shall repair it free of charge and replace the damaged parts.
3. After the expiration of the warranty period, only a certain material fee and appropriate technical service fee will be charged.
4. In case of system operation failure which cannot be solved by itself or by telephone, our technical maintenance personnel shall make solutions (including temporary measures) and schedule within 24 hours after receiving the written notice from the demander and report to the competent leaders of both parties.
5. After the delivery of the equipment, our company will have engineers to pay a return visit to understand the operation of the equipment and provide technical services in a timely manner. Users are welcome to ask any technical questions, and we will reply in time.
