How to perform fault diagnosis of RO membrane module of small and medium-sized automatic ultrapure water equipment? Author: SMEs operating principle of automatic ultra-pure water equipment is the use of selected RO membrane permeability, so the RO membrane problem of course will affect the water quality of the device. So how to diagnose the fault of the RO membrane module? Let me introduce the fault diagnosis of the RO membrane module to the environmental protection editor to help you better use the pure water equipment. Failure symptoms of RO membrane elements other than the RO membrane element itself are often also present on the membrane elements of the reverse osmosis system. Therefore, when investigating the reasons, the attention is always focused on the performance analysis of the membrane elements of the pure water system. When it is found that the RO membrane system of the small and medium-sized automatic ultrapure water equipment is malfunctioning, it is indispensable to obtain the correct judgment through the inspection of the operation records and the analysis of the raw water quality. The fault diagnosis can be carried out in the following order: 1. Refer to the operation record. On the premise that daily operating data records are saved, confirm the operating conditions and conditions of the system, and investigate whether there are abnormal operating conditions; 2. Add necessary data. Determine whether the overall performance of the system is degraded or partial performance degraded. If the performance of the reverse osmosis system is reduced, you can disassemble the membrane element that has the problem, check its appearance and the sealing ring of the connection; 3. Investigation and analysis of the characteristics of the raw water; 4. The membrane removed from the pure water equipment device Component performance inspection, membrane component disassembly inspection (membrane analysis, cleaning test).
