Abstract

Aiming at the problem of redundant symptoms and incomplete information when diagnosing the fault of reverse osmosis system for chemical water treatment in power plant using the result of failure mode and effect analysis. A fault diagnosis method of RO system is proposed based on rough set theory. By analyzing the classical failure modes of RO system, fault diagnosis decision table is built, then fault symptom attributes reduction is made, and the fault diagnosis rules are gained. An instance analysis of a RO system is made, the result shows that this method is feasible and effective and can fulfil the fault diagnosis of RO system and can be a support for making decision for cleaning and maintenance
