Abstract: An object of the present invention is to provide a method for operating a reverse osmosis membrane filtration plant which enables operations including addition of bactericide, chemical cleaning, pre-treatment, and the like which are carried out for the purpose of preventing biofouling of a reverse osmosis membrane module of a reverse osmosis membrane filtration unit highly reliably, highly sensitively, rationally, rapidly and conveniently in a reverse osmosis membrane filtration plant, and the reverse osmosis membrane filtration plant. For this objection, the present invention provides a method for operating a reverse osmosis membrane filtration plant having a raw water intake unit, a pre-treatment unit, and a reverse osmosis membrane filtration unit having a reverse osmosis membrane module in this order, the method including: disposing a biofilm formation base material under conditions that reverse osmosis membrane supply water and/or reverse osmosis membrane non-permeated water in the reverse osmosis membrane filtration unit are/is flowed at a linear speed equal to a non-permeated water linear speed in the reverse osmosis membrane module of the reverse osmosis membrane filtration unit; evaluating a biofilm amount on the biofilm formation base material at a frequency of from once a day to once in six months; and controlling the method for operating a reverse osmosis membrane filtration plant based on results of the evaluation.

Abstract: PROBLEM TO BE SOLVED: To provide a method to obtain fresh water from raw water with high efficiency by a membrane treatment. SOLUTION: The method for making the fresh water includes a turbidity removing process to remove the turbid substance in the raw water to obtain the fresh water free from the turbid substance, a nano filtration process to remove scale components in the water by a nano filter membrane to obtain a filtrate, and a reverse osmosis process to subject the filtrate to the treatment by a reverse osmosis membrane. The microfiltration membrane or ultrafiltration membrane is used in the turbidity removing process and the recovery rate of the fresh water is controlled to ≥90%. COPYRIGHT: (C)2003,JPO
