Common Issues and Solutions for Integrated Water Purifiers

Integrated water purifiers are widely used for their efficient and convenient features, but they may also encounter some typical issues during operation. Here are common faults and their solutions:

1. Turbid water exceeds standard purity levels

Reasons are often due to clogged or damaged filter media layers, or inadequate backwashing. At this point, check if the multi-media filter has clogged, and perform manual forced backwashing promptly; if there is significant loss of filter media, it is necessary to replenish and replace quartz sand and activated carbon. Meanwhile, monitor the changes in raw water turbidity, and increase the pretreatment unit if needed.

2. Water production volume decreased

It could be due to insufficient water pressure, fouled membrane components, or leaks in the piping. It is necessary to investigate the pump's operating status and valve openings, clean the surface contaminants on the ultrafiltration/reverse osmosis membranes, and check and repair any seal issues at the pipe joints. Regular calibration of pressure sensors can prevent erroneous shutdowns caused by misjudgment.

3. Inconsistent Disinfection Effectiveness

Ultraviolet light tubes that age or lack sufficient dosage can affect sterilization rates; it is recommended to test intensity and record usage time every six months. Employing a composite disinfection method (such as ozone + UV) can enhance reliability. Additionally, high levels of organic matter in water can consume disinfectants; pre-treatment with activated carbon can improve the fundamental water quality conditions.

4. Automatic Control System Failure

PLC programming anomalies are often caused by power fluctuations; equipping with a voltage regulator module can effectively prevent them. In cases of lost sensor signals, clean the probe surface and re-calibrate the parameter range. Establishing a habit of regular data backups is conducive to quickly restoring the default mode under factory settings.

Regular inspections, periodic maintenance, and timely response to alarm notifications ensure the stable operation and prolonged lifespan of the integrated water purifier.
