Embodiment Construction

[0015] Exemplary embodiments of the present invention are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0016] In this embodiment, a waterproof adhesive tape (hereinafter referred to as "adhesive tape") is applied between the diversion net of the reverse osmosis membrane element and the reverse osmosis membrane. The tape can be applied on the diversion net, and then bonded to the reverse osmosis membrane, or vice versa. figure 2 is a schematic diagram of one way of coating...

Abstract

The invention provides a sidestream reverse osmosis membrane element which has a simple water way. A side surface of the sidestream reverse osmosis membrane element is a water outlet and one end of the sidestream reverse osmosis membrane element is a water inlet, or the side surface is the water inlet and the end is the water outlet. According to a technical scheme provided by the invention, the reverse osmosis membrane element only has one water inlet, so the water way is simple, convenient installation is realized, and advantages of the sidestream reverse osmosis membrane element are reserved, e.g., easy rolling and a great flow velocity on a membrane surface.

Description

technical field [0001] The invention relates to a side flow reverse osmosis membrane element. Background technique [0002] The common application form of reverse osmosis technology in water treatment is to make a spiral-wound reverse osmosis membrane element, also known as a spiral-wound reverse osmosis membrane element, which has a central tube with multiple holes and a coil wound on the central tube. Alternately stacked multi-layer reverse osmosis membranes and diversion nets. It generally has a cylindrical pressure vessel as the shell, and the central pipe is connected with the two ends of the shell through connectors. [0003] figure 1 It is a schematic diagram of the shape of a side flow reverse osmosis membrane element according to the prior art. Such as figure 1 As shown, there is a central pipe 12 in the casing 11 of the side flow reverse osmosis membrane element. When in use, raw water enters the casing from both ends of the casing, and under the action of pres...
