During the use of ultrapure water machines, the decline in water quality and shortened lifespan have become common problems that plague researchers. In order to save scientific research costs and improve scientific research efficiency, it is imperative to find out the causes of the above problems and solve them in time.
1. The water quality of the ultrapure water machine declines
1. Objective factors
①Raw water problem The raw water quality is not good, and the TDS value is too high, resulting in a large filtration load of the equipment, resulting in a lot of impurities passing through the membrane elements by chance. It is recommended to install pretreatment equipment to effectively reduce the organic content of raw water.
② Absorption of impurities Although the ion concentration of pure water is low when it is first made, it has a strong ability to absorb impurities. If it is not ready-to-use, but stored in a water storage tank or exposed to the air, it is very easy to absorb bacteria, ions, particles and other impurities from the air or the exhaust port of the water storage tank. It is recommended to configure a filter at the exhaust port. If the water storage tank is made of low-grade plastic, the material is not good enough, and the dissolved organic matter will also lead to a decline in water quality. Youpu sterile Water Tank has a double-layer structure design, and the inner layer is made of medical-grade clean plastic, which is non-polluting to pure water.
③The flow rate is too fast. Due to the excessive water pressure or the air resistance of the filter element, the flow rate of the water body is too high, and the filter material layer is quickly penetrated without being exchanged with the resin, so that impurities cannot be filtered out. It is recommended to add a pressure reducing valve to reduce the water pressure, find out the cause of air resistance and solve it in time.
2. Human factors
① Improper use Some operators will use pure water stored for more than 24 hours, and the cleanliness of the water container is not guaranteed. It is recommended that you use clean containers to avoid secondary pollution of pure water.
② Improper maintenance If the water in the water storage tank is not drained regularly, bacteria will easily breed. It is recommended that you use sterile Water Tanks and regularly disinfect the equipment. After the filter element is used for a period of time, the filter material layer may be blocked or even produce mud balls, and the filtering effect will be greatly reduced. If it is not cleaned or replaced regularly, it will inevitably lead to a decline in water quality. It is recommended that you clean and replace the filter element regularly.
Second, the life of the ultrapure water machine is shortened
1. Objective factors
①Environmental factors If the equipment is exposed to direct sunlight for a long time, the aging of the equipment will be accelerated; if the temperature is not suitable, such as extreme low temperature in winter, the pipes will freeze and crack and the filter element will be damaged. It is recommended to place the device in a dark place indoors. When the temperature is low in winter, insulation materials can be used to isolate the cold air.
②Equipment quality There is no doubt that the quality of equipment will directly affect its service life. When purchasing, it is more secure to choose a big brand with a large number of users, high familiarity, and perfect service.
2. Human factors
① Excessive use When there are many scientific research tasks, the frequency of use of the ultrapure water device will increase accordingly. If the equipment is overloaded for a long time, it will accelerate the wear and aging of various components and shorten the service life. The daily operation time of ultrapure water equipment should be controlled within 8 hours.
②Insufficient maintenance Many users have mastered the scientific method of use, but neglected the regular maintenance of the equipment. We should check and maintain the equipment regularly, descale and clean the inside and outside of the equipment, and replace the corresponding parts in time.
The reasons for the decline in water quality and shortened life of ultrapure water machines are introduced here. I believe that through the above sharing, everyone has greater confidence and grasp of equipment maintenance and use.
