Abstract
This invention relates to a reverse osmosis treatment process, particularly a stable reverse osmosis treatment process which prevents a lowering in throughput capacity by carrying out treatment while keeping the permeate flux of a reverse osmosis membrane constant through the time of use of a module. The process of this invention can keep the throughput capacity constant, can prevent adhesion and pollution onto membrane surfaces and fouling thereon, and moreover can maintain stable operation in a continuous run.
