The filter element flushing frequency of ultrafiltration water purifier and reverse osmosis water purifier is different in many aspects
The conventional flushing frequency is different
Ultrafiltration water purifier: under normal use, it is generally recommended to wash once every half a month
to a month. If the local water quality is good and the water impurities are less, it can be appropriately
extended to wash once every 1-2 months; If the water quality is poor, containing more sediment, rust, colloids,
organic matter and other impurities, you need to wash once every 7-15 days. In addition,
if the ultrafiltration water purifier is not used for more than three days, it needs
to be rinsed for about 3-5 minutes when used again; If the deactivation time is more than
10 days or longer, you need to rinse for more than 15 minutes.

Reverse osmosis water purifier: a chemical cleaning is usually carried out after 3-6 months of operation,
depending on the pollution situation. In daily use, the pre-filter
element can be simply washed and replaced regularly to reduce the burden of the reverse osmosis membrane.

The factors affecting the flushing frequency are different
Ultrafiltration water purifier: Water quality is one of the important factors, poor water quality,
flushing frequency needs to increase. The frequency of use also has an impact,
in the case of a large family population and large water consumption, the ultrafiltration water purifier
is used frequently, and the flushing frequency should be appropriately increased, which can be washed every

in the case of a large family population and large water consumption, the ultrafiltration water purifier

10-15 days. In addition, if there are seasonal changes such as algae and microorganisms in the local water source,
the number of washing times should be appropriately increased in the corresponding season.
the number of washing times should be appropriately increased in the corresponding season.
Reverse osmosis water purifier: The pollution of reverse osmosis membrane mainly includes dissolved salt scaling,
organic deposition and microbial breeding, etc. These pollutants are relatively slow to form, but once they occur,
they have a greater impact on the filtration effect. Therefore, the flushing frequency is mainly
related to the hardness of the inlet water quality and the organic content. If the inlet water quality is high
in hardness and the organic content is high, the risk of scaling and pollution of the reverse osmosis membrane

related to the hardness of the inlet water quality and the organic content. If the inlet water quality is high
in hardness and the organic content is high, the risk of scaling and pollution of the reverse osmosis membrane
is large, and the corresponding flushing cycle may need to be shortened to about 3-4 months.
The frequency of use also has a certain impact on it, and the use of frequent reverse osmosis water purifiers may require a flushing in about 5-6 months.
The purpose of irrigation is different
Ultrafiltration water purifier: It is mainly to remove the accumulated particles, colloids and organic
pollutants on the surface of the membrane to prevent it from blocking the membrane hole and affecting
the water flow and water quality. Through regular flushing, membrane flux can be maintained and the
transmembrane pressure difference can be reduced.

transmembrane pressure difference can be reduced.
Reverse osmosis water purifier: In addition to removing impurities, it is more important to restore the desalting rate,
remove scaling, and ensure stable water quality. Because the filtration accuracy of reverse osmosis membrane is very high,
once there is impurities scaling or pollution, it will seriously affect its removal effect on heavy metals, dissolved solids, etc.

Ultrafiltration water purifier: The commonly used washing methods are physical cleaning methods such as forward washing,
backwashing and gas scrubbing, as well as chemical cleaning methods such as pickling and alkali washing. Physical cleaning
backwashing and gas scrubbing, as well as chemical cleaning methods such as pickling and alkali washing. Physical cleaning
methods can be carried out regularly, such as backwashing can be carried out once every 1-2 weeks;
Chemical cleaning is carried out every 2-3 months or more depending on the contamination.
Reverse osmosis water purifier: mainly forward cleaning and deep chemical cleaning, reverse cleaning
is supplemented, and reverse cleaning is only suitable for serious pollution, it is necessary to control
the backwash flow to prevent damage to membrane elements. Due to its relatively complex internal structure,
chemical cleaning requires professional operation, and it is generally recommended to carry out a professional deep chemical cleaning every 1-2 years.
