Abstract
A reverse osmosis (RO) dedicated acidic detergent is composed of the following raw materials in parts by weight: 5 to 10 parts of ammonium citrate, 1 to 2 parts of oxalic acid, 1 to 5 parts of EDTA, 2 to 5 parts of ammonium hydrogen fluoride, and 70 to 90 parts of purified water. The detergent is mainly composed of organic acids, and does not harm the membrane elements on the basis that the cleaning effect is not affected. The detergent is suitable for most RO materials including aromatic polyamide, cellulose acetate, and the like, and can be dissolved in water. The operation is simple, the addition is convenient, the toxicity is low, the application concentration is completely harmless, no residue is left, no accumulated environmental pollution is generated, and the detergent can be widely used in the RO membrane treatment systems in various water treatment industries.
Description
Technical field
The present invention relates to a kind of water treatment agent, be specifically related to a kind of water treatment agent for the special acidity cleaning of counter-infiltration.
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 the fouling of metal hydroxides, calcium carbonate and other types, can cover the surface of film, if irregularly cleaned, just can not maintain normal production, increase energy consumption and pollutant, the safe operation of equipment can not ensure, and service life also can shorten.
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 acidic cleaner of a kind of counter-infiltration, utilize the oxidisability of himself, acidity and the sequestering power with active group, by covering the strippings such as the dirty scale and corrosion product of metal surface, infiltration, dispersion, chelating in washing lotion, to reach the object of cleaning.
In order to achieve the above object, the technical scheme that the present invention takes is:
The special acidic cleaner of a kind of counter-infiltration, the parts by weight of its raw material are:
Citric acid ammonium salt 5 parts-10 parts
Oxalic acid 1 part-2 parts
EDTA 1 part-5 parts
Ammonium acid fluoride 2 parts-5 parts
Pure water 70 parts-90 parts
Main Ingredients and Appearance of the present invention is organic acid, under the prerequisite obtaining good cleaning performance to membrane component without any injury; Be applicable to most of counter-infiltration material, comprise aromatic polyamides, acetate fiber etc.; Miscible with water, simple to operate, add conveniently; Toxicity is low, and working concentration is completely harmless, and discharge noresidue, can not cause pollution of circulation to environment; Be widely used in the reverse osmosis membrane treatment system of all kinds of water treatment field.
detailed description of the invention:
Below in conjunction with specific embodiment, the present invention is described in detail.
Embodiment 1
The special acidic cleaner of a kind of counter-infiltration, the parts by weight of its raw material are:
Citric acid ammonium salt 6 parts
Oxalic acid 2 parts
EDTA 2 parts
Ammonium acid fluoride 2 parts
Pure water 88 parts
Main Ingredients and Appearance of the present invention is organic acid, under the prerequisite obtaining good cleaning performance to membrane component without any injury; Be applicable to most of counter-infiltration material, comprise aromatic polyamides, acetate fiber etc.; Miscible with water, simple to operate, add conveniently; Toxicity is low, and working concentration is completely harmless, and discharge noresidue, can not cause pollution of circulation to environment; Be widely used in the reverse osmosis membrane treatment system of all kinds of water treatment field.
