How does the backwash water filter work?

The backwash water filter is a highly efficient water treatment device. Its working principle is based on reverse water flow technology, which aims to achieve automatic cleaning of the filter element. The core of this technology is to effectively remove impurities accumulated on the surface of the filter element by changing the direction of water flow, thereby maintaining the efficient operation of the filter.
Under normal working conditions of the equipment, the water source containing impurities flows into the filter through the water inlet. The water flows through the multi-layer filtration of the filter element, which can effectively intercept suspended matter, particulate matter, colloids, bacteria and some soluble pollutants in the water, ensuring that the final outflowing water quality meets the user's use standards. However, as time goes by, impurities will gradually accumulate on the surface of the filter element, resulting in a decrease in filtration efficiency. In order to solve this problem, the backwash water filter has the function of automatically starting the backwash program to maintain its filtration performance.
The backwash process usually includes the following key steps:
Stop normal water supply: Before the backwash program is started, the system will first close the normal water supply channel. This measure ensures that the user's daily water needs will not be affected during the backwash process, thereby avoiding unnecessary interference.
Start backwash mode: The system then switches to backwash mode, where the filter element is reversely flushed with a clean water source (such as tap water or water from a water tank). The reversal of the water flow direction causes the water to flush from the bottom of the filter element to the top, effectively flushing away impurities attached to the surface of the filter element. This process not only improves the cleanliness of the filter element, but also extends its service life.
Impurity discharge: During the flushing process, the water flow will flush out the impurities through the drain port to automatically clean the filter element. Through this mechanism, the system can effectively remove the contaminants accumulated on the surface of the filter element, ensuring the high performance of the filter in subsequent use.
Restore normal filtration mode: After the backwash is completed, the system automatically switches back to normal filtration mode and continues to provide users with clean water. This series of automated operations not only improves the user experience, but also reduces the need for manual maintenance.

What are the common faults of backwash water filter?

Power supply and control system failure
The backwash water filter is equipped with an advanced intelligent control system designed to monitor water quality in real time and effectively manage the filtration and backwashing process. However, power failure or control system failure is a common technical problem that may cause the equipment to fail to start, abnormal indicator lights, or the backwashing program to fail to execute normally.
To solve such faults, users should first ensure that the power plug is firmly connected to ensure that the equipment is powered normally. In addition, check the indicator lights and display screen on the control panel to observe whether there are abnormal displays or alarm messages. If the control system fails, it is recommended to contact Tianqin Water Purification Equipment's professional after-sales service team for troubleshooting and repair. Tianqin Water Purification Equipment has an experienced technical team that can quickly and accurately locate the problem and provide practical solutions.
Filter element blockage and aging
The filter element is the core component of the backwash water filter, responsible for effectively intercepting impurities and pollutants in the water. As the use time increases, the filter element may lose its filtering effect due to blockage or aging.
To ensure the performance of the equipment, users should regularly check the status of the filter element and pay attention to whether there are obvious signs of blockage or aging. Replace the filter element in time according to the instructions for use or changes in water quality. Tianqin Water Purification Equipment provides a variety of filter elements for users to choose from to ensure that the equipment always maintains the best filtering effect. If the water quality does not improve after replacing the filter element, it is recommended to contact the technical support team of Tianqin Water Purification Equipment for further inspection and repair.
Failure of backwash function
The backwash function is a core advantage of the backwash water filter, which can automatically clean the filter element and thus extend its service life. However, if the backwash function fails, the filter element will not be effectively cleaned, resulting in a significant decrease in the filtering effect.
To solve this problem, users should check the settings of the backwash program, including whether the parameters such as the time, frequency and water volume of the backwash are correct. If the settings are correct but the function still fails, it may be that the backwash solenoid valve or related components are faulty.
Pipe connection and water leakage problems
The pipe connection part of the backwash water filter is prone to looseness or water leakage, which not only affects the filtering effect of the equipment, but also may pose a potential threat to the water safety of homes or commercial places.
To prevent such problems, users should regularly check the pipe connection part to ensure that it is not loose or leaking, and tighten or replace damaged parts in time.
