40 40 High performance RO membranes for industrial filed

Product Description

FFM4040-OHR
Performance Characteristics      
●FFM ins  anti-oxidation series are mainly used in municipal large-scale desalted water system and industrial wastewater treatment system.
●It has the characteristics of low operating pressure, not easy to be polluted and blocked, stable technical performance, good water quality, high water yield, good pollution resistance, etc., and shows extremely high comprehensive and superior performance in the use process.
●Membrane components have higher oxidation resistance, higher adaptability in special fields and longer service life of membrane.

Important Information
1. Before the installation of membrane components, the system and pipelines shall be completely cleaned to ensure that there is no mechanical impurity causing damage to the membrane.
2. Before the operation of the system, it shall be ensured that the pre-treatment is completed.
3. During the start-up, shutdown, cleaning and other processes of the system, the water inflow shall be slow, from low pressure to high pressure, from low flow to large flow, so as to avoid the impact damage to membrane components caused by the instantaneous rise of pressure and flow. 
4. The membrane element should always be kept wet once water enters.
5. Back pressure on the water producing side should be avoided at all times.
