| Brand Name : | SINOMEMB |
| Model Number : | SNU-HO-2-660 |
| Certification : | NSF |
The core SINOMEMB ® series SNU-HO-2-660 hollow fiber UF membrane element membrane module is ideal for systems with a capacity of 50 m 3 /hr (220 gpm) and below. The 60-inch length of this module is more effective at treating a variety of feedwaters than longer modules. In addition, the diameter of the membrane module is 6 inches , and the size is small, which can realize a relatively compact design , which is very suitable for occasions with limited space . The excellent performance helps customers to achieve a more economical membrane system design , and can be widely used in surface water , well water, seawater , industrial wastewater, secondary and tertiary treatment of sewage and other water treatment applications.

During the operation of the UF system, it is necessary to avoid sudden changes in pressure during system start-up, shutdown, operation, cleaning, maintenance, etc., as well as exceeding the maximum pressure specified in this manual, to prevent possible membrane breakage, sealing, etc. End fall off, membrane shell cracking and other serious damage consequences; this series of products have been treated with anti-corrosion and membrane wire protection before leaving the factory, and the inner membrane wire of the module is in a semi-dry state. For manual operation, the water production rate should be set to 50% of the design water production rate, and the initial water production must be discharged directly and cannot be used as product water.
The normal start-up and normal cleaning and maintenance of the UF system are the key to ensure the long-term normal use of membrane products. Before starting the system, it should be ensured that the parameters of each valve, instrument, pre-processing equipment, signal transmission equipment, power equipment, etc. meet the design specifications and requirements, so as to ensure the safe, stable and up-to-standard operation of the overall system. Please refer to the product technical manual for the debugging and testing work of the system in the early stage.
Failure to operate in strict accordance with the operating limits and guidelines set forth herein voids our limited warranty. If the UF system is out of service, please inject protective liquid inside the membrane module for anti-corrosion treatment, so as to avoid the increase of maintenance cost caused by the large number of microorganisms in the system.
