Abstract
A reverse osmosis (RO) dedicated alkaline detergent is composed of the following raw materials in parts by weight: 5 to 10 parts of sodium tripolyphosphate, 1 to 2 parts of sodium dodecyl benzene sulfonate, 1 to 5 parts of sodium silicate, 1 to 2 parts of trichloroethylene, and 80 to 90 parts of purified water. The detergent is mainly composed of sodium silicate, sodium tripolyphosphate, surfactant, and the like, can effectively organic pollutants such as remove grease, dirt, organic colloid, microbes, and the like on the surface of an RO membrane by using the strong penetrating and dispersing performance of alkali. The detergent can carry out saponification reactions with fatty glyceride to generate primary soap, and thus the oily dirt is converted into water soluble substances and removed. The cleaning effect of the detergent is good, the operation situation of a system is improved, and the operation time of the system is prolonged. The membrane cleaning effect is improved, the membrane service life is prolonged, and the detergent is in a liquid form and is user-friendly.
Description
Technical field
The present invention relates to a kind of water treatment agent, be specifically related to the water treatment agent of the special alkalescence cleaning of a kind of reverse osmosis membrane.
Background technology
Counter-infiltration is a kind of membrane separation technique grown up the sixties in 20th century, and because it is compared with traditional ion-exchange desalting technology, simple to operate, almost do not have discharge of wastewater, operating cost is low, therefore obtains and develops rapidly.
But reverse osmosis membrane surface is very easily subject to the attachment that mud, colloid, oil, biological mucosa, bacterium etc. are insoluble to the various organic pollutions of acid, affects the normal operation of reverse osmosis unit, causes scrapping of reverse osmosis membrane time serious.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide the special alkaline cleaner of a kind of counter-infiltration, the efficient mud, colloid, oil, biological mucosa, bacterium etc. removing reverse osmosis membrane surface is insoluble to the various organic pollutions of acid.
In order to achieve the above object, the technical scheme that the present invention takes is:
The special alkaline cleaner of a kind of counter-infiltration, the parts by weight of its raw material are:
Sodium phosphate trimer 5 parts-10 parts
Neopelex 1 part-2 parts
Sodium metasilicate 1 part-5 parts
Trichloro-ethylene 1 part-2 parts
Pure water 80 parts-90 parts
Main component of the present invention is sodium metasilicate, sodium phosphate trimer, surfactant etc., the strong penetrating power of alkali and dispersibility is utilized effectively to go to eat to the organic pollution such as grease soils, organic colloid, microorganism on reverse osmosis membrane surface, their action principle be can and greasy dirt in fatty acid glycerine generation saponification formation nascent soap, make greasy dirt become water miscible material and be removed.Cleaning performance is good, improves the operation conditions of system, makes the duration of runs of system longer; Improve the cleaning performance of film, extend the life-span of film; Liquid preparation, easy to use.
detailed description of the invention:
Below in conjunction with specific embodiment, the present invention is described in detail.
