1, membrane pollution: the reverse osmosis membrane in ultra-pure water equipment will be polluted with the increase of use time, resulting in the decline of water quality and equipment performance, so it is necessary to clean and replace the reverse osmosis membrane regularly.
2. Unstable water quality: When the water quality of ultra-pure water equipment is unstable, there will be problems, so it is necessary to check the inlet water quality regularly to ensure the water quality is stable.
3. Insufficient water pressure: When the water pressure in ultra-pure water equipment is insufficient, the equipment cannot operate normally, so it is necessary to check whether the water inlet pipeline is blocked or leaking.
