Abstract

The invention discloses an on-line reverse osmosis system, which is characterized by the following: modifying original forward cleaning reverse osmosis system; connecting reverse osmosis discharge valve in the entrance of original water of reverse osmosis film component; setting partition valve between each segment of original water entrance of reverse osmosis film component and cleaning valve except the first segment.

Description

technical field [0001] The invention belongs to the technical field of reverse osmosis water treatment systems, and in particular relates to a reverse osmosis system that uses a reverse osmosis system cleaning device to realize online backwashing. Background technique [0002] At present, the reverse osmosis system is an important equipment for desalination of water quality worldwide, and is widely used in the field of water treatment technology. Generally, the reverse osmosis system is used for a period of time, and the reverse osmosis membrane elements will be fouled. This is a common thorny problem in the reverse osmosis system. During normal operation, this requires the use of chemical cleaning agents to clean the reverse osmosis membrane elements in the system. After the reverse osmosis membrane element is chemically cleaned, most or part of its performance can be restored. When the cleaning is no longer effective and the function does not meet the requirements of use,...
