Preventive maintenance and reverse osmosis pure water equipment, RO desalination membrane method

RO membrane is pure water equipment commonly used reverse osmosis membrane, can in most domestic use is Hyde and dow brand, reverse osmosis pure water is commonly used in water treatment equipment, the introduction to the RO reverse osmosis pure water equipment, RO pure water machine can also be referred to as reverse osmosis pure water machine. Reverse osmosis pure water equipment, reverse osmosis membrane was mainly used for water desalination processing, so everyday use this pure water equipment, how to master the use of reverse osmosis pure water machine skills? We source water treatment filter simple list several kinds of methods:

using the method of chemical cleaning RO pure water machine film

1. Enzymatic detergent with enzymatic detergent processing film, the organic matter pollution, especially for protein, oil and other organic pollutants are particularly effective, if in 50 ℃ - Cleaning effect better under 60 ℃, average after running for ten days or half a month with 1% of the enzyme detergent to a membrane cleaning under low pressure, due to the enzymatic detergent concentration is low, so requires dipping time is longer.

citric acid solution, under high pressure or low pressure, with 1% 2% of citric acid aqueous solution for continuous or circulation of membrane, the method of Fe ( 哦) 3 pollution has good cleaning effect.

2。 Strong brine, the body pollution serious membrane used in concentrated brine cleaning is effective, this is due to the high concentration of salt water can decrease the interaction between colloidal, promote colloidal condensed to form micelles.

3。 Hydrogen peroxide solution, such as 0. 5 l, with 30% H2O2 with 12 l deionized water dilution, and then clean the membrane surface, this method is particularly effective to organic pollution.

4。 Water-soluble emulsion, used for cleaning contaminated with oil and iron oxide film is very effective, 30 - general cleaning 60 minutes.

using the principle of physics for cleaning

the simplest physical cleaning method is to use low pressure high velocity through the water flushing 30 minutes into the membrane, it can make the waterproof performance of membrane have a certain degree of recovery, but in the long run, permeable rate drop, still can be mixed with water and air fluid in low pressure washing membrane surface for 15 minutes, cleaning polluted by organic matter in the early years of the film in this way is effective.

the above is our my simple filter source water treatment equipment category, if you have any other question can be directly call the filter source water treatment equipment technical consultation.
