Abstract

The invention discloses a reverse osmosis membrane off-line cleaning agent which is mainly prepared by mixing the following raw materials in percentage by weight: 0.3-0.7% of bactericide, 0.01-0.03% of surfactant, 0.05-1% of sodium citrate, 1-3% of caustic soda flakes, 3-6% of citric acid and the balance of water. The reverse osmosis membrane off-line cleaning agent disclosed by the invention has the advantages of good cleaning effect, no corrosion, environmental friendliness, high efficiency and increase of cleaning rate.

Description

technical field [0001] The invention relates to an off-line cleaning agent for a reverse osmosis membrane, which belongs to the technical field of water treatment. Background technique [0002] my country attaches great importance to the purification of industrial water, drinking water and discharged sewage to prevent sewage from polluting soil, rivers, lakes and other wetlands. In addition, more attention is paid to the purification of drinking water. Therefore, water treatment technology and water treatment equipment have emerged as the times require. RO membranes, DOW membranes and other membrane elements currently used in water treatment equipment and various reverse osmosis membranes will breed some microorganisms, deposit colloidal debris particles, oxides, organic matter and salts and other pollutants during the water treatment process. Scaling is formed, which seriously affects the safe operation of equipment. Therefore, regular cleaning is required to ensure that...
