How To Extend The Flushing Cycle Of Ultrafiltration Water Purifier Filter Element?
Install pre-filter: The pre-filter installed in front of the ultrafiltration water purifier can effectively
filter out large particle impurities in the water, such as sediment, rust, etc.,
reduce the filtration burden of the ultrafiltration filter element, thereby extending its flushing cycle.
The screen accuracy of the pre-filter is generally about 40-100 microns, which can intercept most visible impurities.
Adding coagulants or softeners: If the raw water contains more suspended matter or colloids,
you can consider adding coagulants, such as polyaluminum chloride (PAC), aluminum sulfate or polyferric sulfate,
etc., to promote the flocculation of particles, so that it is easier to be intercepted by the pre-filter.
For areas with hard water quality and high calcium and magnesium ion content in water,
softeners can be added or water softening equipment can be installed to prevent
scaling on the surface of ultrafiltration membrane and extend the service life of filter element.
Optimize the use environment and habits
Pay attention to the inlet water quality: pay attention to the local water quality changes, in the period of poor water quality,
such as after heavy rain, pipeline maintenance, etc., appropriately increase the flushing frequency.
If the water source is found to be contaminated or smelly, the ultrafiltration water purifier should be washed in time,
and the pre-filter element should be replaced if necessary.
Control the frequency of use: reasonably arrange the use time of the ultrafiltration water purifier to avoid excessive
fatigue of the filter element caused by long-term continuous use. When no need to use,
timely close the water purifier power supply and water inlet valve to reduce the pressure of the filter element.
Regular maintenance and monitoring
Physical cleaning: Regular physical cleaning of the ultrafiltration water purifier, such as backwashing, positive washing,
etc. Backwashing can loosen the impurities on the surface of the filter element and discharge them from the system;
Positive flushing further removes residual contaminants. In general, backwashing
can be performed once a week or every two weeks, and positive washing can be performed once a month.
Chemical cleaning: According to the material and pollution of the ultrafiltration membrane,
choose the appropriate chemical cleaning agent, such as dilute acid, dilute alkali, oxidizer,
etc., and regularly carry out chemical cleaning to remove stubborn dirt and microorganisms.
The cycle of chemical cleaning is generally 2-3 months or adjusted according to the actual situation.
Monitor the performance of the filter element: Regularly check the performance indicators
of the ultrafiltration filter element, such as flux, pressure difference, etc. When the flux
drops significantly or the pressure difference increases, it indicates that the filter element is seriously polluted and needs to be cleaned or replaced in time.
Install and save correctly
Ensure correct installation: Install in strict accordance with the installation instructions
of the ultrafiltration water purifier to ensure that the filter element is installed in place, no leakage,
no loosening, etc., to ensure that the water flow is uniform through the filter element,
to avoid excessive local pressure caused by improper installation and accelerate the damage of the filter element.
Properly store the filter element: If the ultrafiltration water purifier needs to be disabled for

a long time, the filter element should be removed, cleaned and soaked in the protective liquid to
prevent the filter element from drying, deformation and breeding bacteria. When used again, the filter element should be fully washed.
Optimized operating conditions
Control pressure and flow: Ensure that the ultrafiltration water purifier operates within the specified
pressure and flow range to avoid impact and damage to the filter element caused by too high pressure or too large flow.
The working pressure of the general ultrafiltration water purifier is between 0.1-0.4MPa,
which can be adjusted according to the product instructions.
Stable operating environment: Keep the operating environment of the ultrafiltration water purifier stable and avoid drastic changes in temperature,
humidity and other factors. The temperature is too high or too low may affect the performance and life of the filter element, and the appropriate operating temperature is generally between 5℃-35℃.
