The reasons for the decrease in water quality of ultra pure water equipment during use are as follows:

1. Pretreatment filter element: Some users use raw water with poor quality, with a large amount of impurities or sediment, which are not treated through bag filters. The pre-treatment effect is not ideal, and long-term use can lead to blockage of membrane components in the equipment, resulting in a decrease in the quality of water produced by pure water equipment.

2. Reverse osmosis membrane: Reverse osmosis membrane components are one of the core components in pure water equipment, with a general service life of 2-3 years. If the inlet water quality is unqualified or used continuously for a long time, the service life of the membrane components will be shortened. Once the reverse osmosis membrane components are contaminated or blocked, it will inevitably affect the water quality of the equipment's output. Therefore, we must regularly clean and maintain the membrane components reasonably.

3. Purification column: Purification columns are commonly used consumables for pure water equipment and have a certain service life. We need to replace them regularly. If the filter element grows bacteria or has become ineffective, and we do not replace it in a timely manner, it will cause the quality of the produced water to deteriorate.

4. Operation error: The operation requirements of pure water equipment are very strict. If we use it improperly, it can cause damage to the core components of the equipment, and even shorten the service life of the equipment, thereby affecting the water quality of the equipment.

The above is an introduction to the reasons for the decrease in water quality during the use of ultra-pure water equipment. Therefore, in order to avoid the phenomenon of water quality decrease during the use of ultra-pure water equipment, we need to constantly monitor the operating status of the equipment, so that when equipment malfunctions, they can be detected in a timely manner, resolved as soon as possible, and losses can be reduced.
