SNU-HM type hollow fiber submerged curtain UF adopts a special patented technology in the spinning process and adds a reinforced reinforced lining, so it has all the advantages of PVDF material membrane filaments, but also has high strength and toughness. specialty. This feature fundamentally makes up for the biggest shortcoming of the traditional PVDF membrane, which is low in strength, easy to break, and cannot be well adapted to high-intensity aeration environments. It is of great milestone significance for the application of PVDF membrane in the MBR process. At the same time, since the design flux of the SNU-HM hollow fiber submerged curtain UF membrane is generally set to an appropriate value according to different water qualities, its online cleaning cycle is relatively long, about 7 to 17 days.

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 withstand 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.
