Specific maintenance precautions for membranes in purified water equipment

In the purification water equipment, the maintenance of the membrane is the main, and the membrane is the core component
of the purified water equipment.

After the equipment has been running for a period of time, a large number of pollutants have been adsorbed and deposited on the membrane of the purified water equipment that need to be removed in time for the next efficient operation
.

If filtration is carried out each time the cleaning is not in place, the contamination will further accumulate, accumulating to the phenomenon that
the flow channel on the membrane surface is blocked and the cleaning agent cannot penetrate into it.

At the same time, due to the long-term pressure operation, the contaminants will be densely realized, which will lead to the cleaning and recovery of the membrane is extremely difficult, and eventually lead to the scrapping
of the membrane.

The following is to introduce the specific maintenance precautions of the membrane in the purified water equipment: generally there is a decrease in water production; The quality of the produced water and the desalination effect have become poor; When the pressure difference between the various sections of the system becomes larger, it means that the membrane pollution is more serious and needs to be cleaned up
.

The chemical cleaning liquid used in general is citric acid, hydrochloric acid, sodium bisulfite, etc.
, and different solutions
are used for different pollution.

The tools are simple, water tanks, pumps, filters, preferably with a pressure gauge flow meter
.

If reverse osmosis is not used for a long time (3 days upwards), sodium bisulfite solution needs to be injected into the reverse osmosis membrane module to inhibit microbial growth
.

If the previous membrane has not been efficiently cleaned, it has been polluted to a very low flux, it must be the result of accumulation over time, do not expect to use a certain efficient membrane cleaner to remove all the pollutants at once, as if a serious illness, expect to take a medicine to immediately restore health, that is completely impractical
.

The reverse osmosis membrane should be cleaned regularly so as to ensure the health and safety
of our water.
